Panasonic has achieved the world’s highest energy conversion efficiency of 16.09% for a perovskite solar module (aperture area 802 cm2: 30-cm x 30-cm x 2-mm thick) by developing lightweight technology using a glass substrate and a large-area coating method based on inkjet printing. This was carried out as part of the project of the New Energy and Industrial Technology Development Organization (NEDO), which is working on the “Development of Technologies to Reduce Power Generation Costs for High-Performance and High-Reliability Photovoltaic Power Generation” to promote the widespread adoption of solar power generation.

This inkjet-based coating method that can cover a large area reduces manufacturing costs of modules. In addition, this large-area, lightweight, and high-conversion efficiency module allows for generating solar power highly efficiently at locations where conventional solar panels were difficult to install, such as façades.

Going forward, NEDO and Panasonic continue to improve perovskite layer materials, aiming to achieve high efficiency comparable to that of crystalline silicon solar cells and establish technologies for practical application in new markets.

By focusing on the inkjet coating method that enables the raw material to be coated precisely and uniformly, Panasonic applied that technology to each layer of the solar cell including perovskite layer on glass substrate and realized high power conversion efficiency for a large-area module.

The new Cerbo GX, along with the optional GX Touch 50 display, were announced and demonstrated at METS, November 2019. GX products are Victron Energy state-of-the-art monitoring solution. The family consists of the different GX products, and their accessories.

The GX-device lies at the heart of the system – providing monitoring, and operating as the communication-centre of your installation. All the other system-components – such as inverter/chargers, solar chargers, and batteries – are connected to it. Monitoring can be carried out locally and remotely – via our free-to-use Victron Remote Management portal (VRM). The GX-device also provides Remote firmware updates and allows inverter/charger settings to be changed remotely.

Personally I’m a great fan of GX devices, the Color Control GX, Venus GX and more – all being a part of the Victron GX product range.

Detailed introductory blogpost by Panbo

However, my 6 years personal experience is with the Color Control GX model – so I’d be doing you the reader a disservice by reviewing the Cerbo GX. Also, as I blog for Victron, I admit to a natural and faithful bias. It seems only right and proper then to let an independent reviewer give you their take on this exciting new product. What I can say though – is that going by the review on Panbo, the product will be in great demand.

For a detailed introduction, I recommend reading the Panbo blog post by Ben Ellison:

Victron Cerbo GX, good AC/DC power monitoring gets better.

Introductory video

GX Touch 50 display

The GX Touch 50 is the optional display for the Cerbo GX. Its water proof, thin, and easy to mount. There is a cable coming out on the back with two plugs on it: the HDMI goes into the HDMI port on the Cerbo, and the USB (used to power the display) goes into one of the USB sockets. For all details, including dimensions and the manual, see the GX Touch 50 product page.

Optional DIN rail adapter

The optional DIN rail adapters are to easily mount the Cerbo GX on a DIN-Rail. Dimensions and details are available on its page on our website.

Conclusion

When you consider just how far GX devices have come in the last 6 years (just take a look back to 2014), then the Cerbo GX is to my mind the ultimate GX turbo charged device for connectivity.

Tesla model 3 cars,now made in China.Tesla has delivered its first cars made in China, marking a major milestone for the electric vehicle maker.

Fifteen Tesla Model 3 cars were handed over at the company’s so-called “Gigafactory” near Shanghai.

It comes as Elon Musk’s company aims to secure a significant slice of the world’s biggest car market.

Tesla’s move into the country comes as the trade war has forced other American companies to shift production out of China.

During a ceremony at the company’s multi-billion dollar plant in Shanghai, 15 of its employees received cars they had purchased.

The event means deliveries of cars have started a little over a year after construction of the factory got underway.

http://https://www.youtube.com/watch?v=olUBAIvoLpo

California-based Tesla said that it wanted to start handing over vehicles before the Lunar New Year beginning on 25 January, and now plans to scale up deliveries from the start of 2020.

The Chinese-made Model 3, priced at $50,000 (£38,000) before subsidies, will compete with local electric car makers, including NIO and Xpeng Motors, as well as global brands such as BMW and Mercedes-Benz.

US technology giants Apple, Google, HP, and Dell have all reportedly started the process of moving production from China to other Asian countries.

That’s as US tariffs on Chinese-made goods make them more expensive when they are imported into America, or companies have to absorb the cost themselves.

It also comes after intense pressure from US President Donald Trump for American companies to bring back manufacturing to the US. In August Mr Trump issued a demand for all US firms to move production out of China.

However, Tesla doesn’t plan to export the cars it makes in China to the US, where they would be hit with tariffs. Instead it wants to sell these Tesla Model 3 cars in China itself.

Previously Tesla was exporting all of the cars it sold in China from the US, which meant they were hit with tariffs in China.

The company isn’t just expanding its manufacturing into China. In November, it revealed plans to build a huge European production facility on the outskirts of Berlin in Germany.

Everybody wants the best solar battery in Ghana.There are certain specifications you should use when evaluating your solar battery options, such as how long the solar battery will last or how much power it can provide. Below, learn about all of the criteria that you should use to compare your home energy storage options, as well as the different types of solar batteries.

LITHIUM VS AGM Ghana

How to compare your solar storage options

As you consider your solar-plus-storage options, you’ll come across a lot of complicated product specifications. The most important ones to use during your evaluation are the battery’s capacity & power ratings, depth of discharge (DoD), round-trip efficiency, warranty, and manufacturer.

Capacity & power

Capacity is the total amount of electricity that a solar battery can store, measured in kilowatt-hours (kWh). Most home solar batteries are designed to be “stackable,” which means that you can include multiple batteries with your solar-plus-storage system to get extra capacity.

While capacity tells you how big your battery is, it doesn’t tell you how much electricity a battery can provide at a given moment. To get the full picture, you also need to consider the battery’s power rating. In the context of solar batteries, a power rating is the amount of electricity that a battery can deliver at one time. It is measured in kilowatts (kW).

A battery with a high capacity and a low power rating would deliver a low amount of electricity (enough to run a few crucial appliances) for a long time. A battery with low capacity and a high power rating could run your entire home, but only for a few hours.

Depth of discharge (DoD)

lithium vs AGM ,DEPTH OF DISCHARGE GRAPH,GhanaMost solar batteries need to retain some charge at all times due to their chemical composition. If you use 100 percent of a battery’s charge, its useful life will be significantly shortened.

The depth of discharge (DoD) of a battery refers to the amount of a battery’s capacity that has been used. Most manufacturers will specify a maximum DoD for optimal performance. For example, if a 10 kWh battery has a DoD of 90 percent, you shouldn’t use more than 9 kWh of the battery before recharging it. Generally speaking, a higher DoD means you will be able to utilize more of your battery’s capacity.This has always been an issue in Ghana .Most people have erroneous impression that batteries need to be completely drained for batter performance.

Round-trip efficiency

A battery’s round-trip efficiency represents the amount of energy that can be used as a percentage of the amount of energy that it took to store it. For example, if you feed five kWh of electricity into your battery and can only get four kWh of useful electricity back, the battery has 80 percent round-trip efficiency (4 kWh / 5 kWh = 80%). Generally speaking, a higher round-trip efficiency means you will get more economic value out of your battery.

Battery life & warranty

For most uses of home energy storage, your battery will “cycle” (charge and drain) daily. The battery’s ability to hold a charge will gradually decrease the more you use it. In this way, solar batteries are like the battery in your cell phone – you charge your phone each night to use it during the day, and as your phone gets older you’ll start to notice that the battery isn’t holding as much of a charge as it did when it was new.

Your solar battery will have a warranty that guarantees a certain number of cycles and/or years of useful life. Because battery performance naturally degrades over time, most manufacturers will also guarantee that the battery keeps a certain amount of its capacity over the course of the warranty. Therefore, the simple answer to the question “how long will my solar battery last?” is that it depends on the brand of battery you buy and and how much capacity it will lose over time.

For example, a battery might be warrantied for 5,000 cycles or 10 years at 70 percent of its original capacity. This means that at the end of the warranty, the battery will have lost no more than 30 percent of its original ability to store energy.

Manufacturer

Many different types of organizations are developing and manufacturing solar battery products, from automotive companies to tech startups. While a major automotive company entering the energy storage market likely has a longer history of product manufacturing, they may not offer the most revolutionary technology. By contrast, a tech startup might have a brand-new high-performing technology, but less of a track record to prove the battery’s long-term functionality.

Whether you choose a battery manufactured by a cutting-edge startup or a manufacturer with a long history depends on your priorities. Evaluating the warranties associated with each product can give you additional guidance as you make your decision.

Automotive companies are jumping on the energy storage bandwagon

Home energy storage technology and electric vehicles are a lot alike: they both use advanced batteries to create more efficient, sustainable products that can reduce greenhouse gas emissions.

As electric vehicles become more popular, more companies are dedicating significant research and development funds to developing batteries, and they’re expanding into the energy storage business. Tesla is the first mainstream example (with their Powerwall battery), but Mercedes-Benz and BMW are also bringing standalone batteries to the market in 2017.

How long do solar batteries last?

There are two ways to answer this question and the first is to determine how long a solar battery can power your home. In many cases, a fully charged battery can run your home overnight when your solar panels are not producing energy. To make a more exact calculation, you’ll need to know a few variables, including how much energy your household consumes in a given day, what the capacity and power rating is for your solar battery and whether or not you are connected to the electric grid.

For the sake of a simple example, we’ll determine the size of a battery needed to provide an adequate solar plus storage solution with national average data from our research at Nocheski Solar. The average Ghana household will use roughly 15 kilowatt-hours (kWh) of energy per day and a typical solar battery can deliver some 5 kWh of capacity. Thus a very simple answer would be, if you purchased three solar batteries, you could run your home for an entire day with nothing but battery support.

In reality, the answer is more complicated than that. You will also be generating power with your solar panel system during the day which will offer strong power for some 6-7 hours of the day during peak sunlight hours. On the other end, most batteries cannot run at maximum capacity and generally peak at a 90% DoD (as explained above). As a result, your 5 kWh battery likely has a useful capacity of 4.5 kWh.

Ultimately, if you are pairing your battery with a solar PV array, one or two batteries can provide sufficient power during nighttime when your panels are not producing. However, without a renewable energy solution, you may need 3 batteries or more to power your entire home for 24 hours. Additionally, if you are installing home energy storage in order to disconnect from the electric grid, you should install a few days’ worth of backup power to account for days where you might have cloudy weather.

 

Solar battery lifespan

The general range for a solar battery’s useful lifespan is between 5 and 15 years. If you install a solar battery today, you will likely need to replace it at least once to match the 25 to 30 year lifespan of your PV system. However, just as the lifespan of solar panels has increased significantly in the past decade, it is expected that solar batteries will follow suit as the market for energy storage solutions grows.

Proper maintenance can also have a significant effect on your solar battery’s lifespan. Solar batteries are significantly impacted by temperature, so protecting your battery from freezing or sweltering temperatures can increase its useful life. When a PV battery drops below -1.1 ° C, it will require more voltage to reach maximum charge; when that same battery rises above the 32.22 ° C threshold, it will become overheated and require a reduction in charge. To solve this problem, many leading battery manufacturers, like Tesla, provide temperature moderation as a feature. However, if the battery that you buy does not, you will need to consider other solutions like earth-sheltered enclosures. Quality maintenance efforts can definitely impact how long your solar battery will last. Temperatures in Ghana range between 25-35 deg Celsius.

What are the best batteries for solar?

Batteries used in home energy storage typically are made with one of three chemical compositions: lead acid, lithium ion, and saltwater. In most cases, lithium ion batteries are the best option for a solar panel system, though other battery types can be more affordable. Order you Lithium batteries in Ghana here

  1. Lead acid

    Lead acid batteries are a tested technology that has been used in off-grid energy systems for decades. While they have a relatively short life and lower DoD than other battery types, they are also one of the least expensive options currently on the market in the home energy storage sector. For homeowners who want to go off the grid and need to install lots of energy storage, lead acid can be a good option.This is the most common solar battery type in Ghana.

  2. Lithium ion

    The majority of new home energy storage technologies, such as the , use some form of lithium ion chemical composition. Lithium ion batteries are lighter and more compact than lead acid batteries. They also have a higher DoD and longer lifespan when compared to lead acid batteries.  However, lithium ion batteries are more expensive than their lead acid counterparts.This is the least common solar battery type in Ghana

  3. Saltwater

    A newcomer in the home energy storage industry is the saltwater battery. Unlike other home energy storage options, saltwater batteries don’t contain heavy metals, relying instead on saltwater electrolytes. While batteries that use heavy metals, including lead acid and lithium ion batteries, need to be disposed of with special processes, a saltwater battery can be easily recycled. However, as a new technology, saltwater batteries are relatively untested, and the one company that makes solar batteries for home use (Aquion) filed for bankruptcy in 2017.This battery type is virtually non existent in Ghana.


Solar Power ,energy excitement in Nigeria.The market at Sabon Gari in Kano state, Nigeria, has 12,000 shops where you can buy everything from vegetables to visual arts. It’s so big they call it ‘Mini Africa’. Several kilometres of bustling passageways and roads, packed with shoppers and the shouts of traders calling attention to their bargains, makes for an exhilarating atmosphere …you simply can’t visit Nigeria and not go there!

However until recently there’s been something else in the atmosphere, too: quite a lot of smoke!

Noise and fumes

Grid electricity supply problems resulted in 72% of the shops which needed electricity deciding to generate their own power using petrol and diesel generators – a survey found. Apart from the pollution and the noise, the market regularly experienced destructive fires causing damage estimated in the millions of Naira.

Survey, design, install

The Nigerian based off-grid energy specialist Rensource – who aims to build West Africa’s largest portfolio of electricity micro-grid utilities using best-in-class technologies – were asked to carry out the installation.

Rensource recruited and trained 100 engineers, administrative staff, and craftsmen. Like so many countries, Nigeria has a large jobless population – new recruits were drawn from amongst Nigeria’s unemployed.

The first goal was to win the confidence of market stall holders that reliable power provision could be a reality – it was something no one had experienced before. A ‘needs’ survey provided the team with information essential to their system design …some shops needing only lighting; others had  air-conditioning and refrigeration units.

How was it achieved

Working from survey results, a colossal 1.6MWh bank of Lithium-iron Phosphate batteries from hybrid battery manufacturer and technology partner BOS AG, based in Germany was selected as the power storage solution. The power installation was zoned into 160 10kWh systems – each providing power for between 60 and 80 shops.

800kVA of power is made available using 160 Victron MultiPlus inverter/chargers. These inverters have a peak power capability equal to double their continuous output – which ensures smooth power supply even as air conditioning units, for example, cycle on-and-off.  320 Blue solar MPPTs 150/70 units harvest the power from a 1.6MWp solar array, optimising the charge current to the Lithium iron battery bank.

The system allows for future expansion – which is just as well because business is booming and demand for power is growing.

This clean electricity – made affordable by smart meters – brings only benefits it seems: Whereas the price of generator-produced electricity was around 1000 Naira per day, smart energy has brought that cost down to 116 Naira, typically.

International recognition

The success of this huge project has received deserved international recognition – Rensource won the Excellence in Climate Solutions award at the Transformational Business Awards ceremony (also known as ‘the Oscars of the renewables world’) which was held in June 2019, hosted by The International Finance Corporation (World Bank Group and Financial Times.

Since the completion of this project, four more markets now benefit from renewable electricity with a further fourteen scheduled. These developments are bringing welcome employment and training to enthusiastic young people who are really enjoying being involved with such a worthwhile scheme.

Veeresh Anehosur of BOS AG says: The key to these mini grids and micro utility projects is that they need to be commercially attractive and sustainable in long-term. This is possible only if the technology works flawlessly over the years. ‘Low’ or ‘No’ system downtime and good system-level performance helps win customer confidence in the project – which decreases non-payment risk …a perfect scenario to recoup the initial investment. How do you ensure an efficient and cost-effective mini grid over time? One key element is to include lithium. Lithium has one of the least LCOE [Levelized Costs of Energy] compared to Lead acid. For projects where an initial low-capital investment is critical, a combination of Lead acid and Lithium can be used which gives a cost-effective high-performance solution.

Let’s have a look around the market, and hear how market traders are getting on with their new clean power:


How the Digital Inverter Compressor Has Transformed the Modern Fridge.For decades, Refrigerators or Fridges  had single-speed compressors that were always either off or on. A compressor is the engine that powers the refrigeration cycle, moving refrigerant through the inner and outer heat exchange pipes. With a single-speed compressor, when the temperature inside the fridge reaches above a certain temperature, the compressor suddenly switches on – a noise almost everyone is familiar with. The single-speed compressor operates at full power, producing enough cool air until the temperature has sufficiently decreased before abruptly shutting off.

Enter the digital inverter compressor (a compressor that can operate at variable speeds because it is operated with a digital inverter). Unlike the standard single-speed compressor, which is either off or operating at full speed (typically about 3,600rpm), the digital inverter compressor is almost always on, but can operate at different speeds – from 1,100 to 4,300rpm. This ensures high efficiency and consistent temperature inside the refrigerator. It also results in significant cost savings, a reduced carbon footprint, less noise and a longer lifespan for the compressor. The digital inverter compressor is one of the most important innovations in the history of Fridges and food preservation and Samsung has led the way.

Today, digital inverter compressors are the main technology used in Samsung’s signature appliances eg, air conditioners, washing machine & Fridges, including those that are part of the Chef Collection, the T9000, as well as food showcases and large-capacity premium Fridges. This has played no small role in Samsung’s ascent to become the world’s top refrigerator manufacturer.

In addition, Samsung has become a technical leader, as one of the world’s top manufacturers of this game-changing technology. Samsung produced more than 40% of the world’s digital inverter compressors in 2014 as other major manufacturers now use Samsung’s superior compressors in their Fridges.

Samsung really began its rise in this area in 1999 when the company pushed investment in BLDC (brushless direct current) inverter compressors. Since then, Samsung has continued to expand its investment in research and development, hiring a highly skilled team of researchers, which has enabled the company to remain on the cutting edge of technology. From 2000 to 2014, Samsung sold a total of 27.5 million BLDC inverter compressors, which are highly efficient and less noisy compared to a single-speed induction motor compressor. BLDC motors are also better in terms of reliability and longevity. The current Chef Collection refrigerator employs a fifth generation technology of BLDC inverter compressor.

The benefits are obvious. A fridge with a Samsung digital inverter compressor consumes up to 46.9% less energy than a single-speed induction motor compressor, and thus contributes far less in the way of greenhouse gases. Because the digital inverter compressor gradually speeds up and slows down, it does not have to work as hard to manage the temperature. This means that Fridges with digital inverter compressors suffer less wear and tear on components and are therefore far more durable than fridges with conventional compressors. This has allowed Samsung to offer a 10-year warranty on its digital inverter compressors.

The lack of abrupt starts and stops means no sudden, potentially startling disruptive noises interrupting your dinner. Digital inverter compressors are also far less noisy overall: up to 3 decibels quieter. And the consistent, uniform cooling that maintains the desired temperature means food lasts longer because changes in temperature can lead produce, meat, fish and dairy to spoil more quickly. It all means that consumers will save money on both their electric bills and food costs.

When Samsung sought input from its highly influential group of culinary experts, also known as the Club des Chefs, they emphasized that temperature uniformity is a crucial component of any fridge that may be used in a Michelin-starred kitchen. Chef Collection Fridges boast “Chef Mode,” which ensures that the temperature fluctuates no more than plus or minus 0.5 degrees celsius. The Chef Collection refrigerator is equipped with three evaporators and two compressors to control humidity. It is also made of stainless steel panels, which help to keep the temperature consistent.

These Digital Inverter technology based appliances are best used with solar power options for 2-5 bedroom homes from Nocheski


Interfacing for up to 25 charge controllers

Adding to Victron’s comprehensive range of Solar Charge Controllers, we can now announce new models with VE.Can connectivity. These currently include the SmartSolar MPPT 150/70 & 150/100 VE.Can with auto-select voltage for systems of 12, 24, 36 and 48 Volts.These new models are replacements for the BlueSolar MPPT 150/70 & 150/85 CAN-bus generation.The new VE.Can 150/70 and 150/100 models are now in stock and available for delivery. Further models will follow and are detailed later in this blog. Dealers can check availability and stock levels via E-Order.

Why VE.Can?

With the VE.Can interface up to 25 Charge Controllers can be daisy-chained and connected to a Color Control GX or other GX device. Each controller can be monitored individually, for example on a Color Control GX and on the VRM website.

VE.Direct and Bluetooth data communication are also features of these controllers.

To learn more about data communication such as VE.Can – see the PDF ‘Data communication with Victron Energy products’, in our Whitepapers section of the main website.

Comparison of VE.Can SmartSolar MPPT to the previous BlueSolar MPPT CAN-bus generation

  • Improved: each charger is displayed individually on a GX Device and on the VRM Portal; whereas with the previous models all units were operating synchronously and were seen as one; which made it impossible to see individual PV string performance.
  • Improved: supports ESS and control by Intelligent (canbus) batteries, just like today’s VE.Direct models; which was not possible with the previous generation. Note that this will require Venus OS v2.40, which is not yet released yet but is expected in October.
  • Synchronisation: the mechanism to operate synchronously is the same as before: equal device instances enables synchronised charging. Since they are all configured with Device instance 0 out of the box; they’ll automatically start synchronising as soon as you connect them together with the network cable.

Note: These new models cannot synchronise with the previous generation. They can of course still be used together in the same system; but will then operate autonomously.

Future developments & firmware

In addition to these new 150V, 70 & 100A models, there will also be a 150V, 85A plus 250V, 70A & 100A models. They are expected by the end of this year.

Furthermore some special and not commonly used features have not yet been released, but will come later as a firmware update. These are the virtual load output, street light, alternate TX/RX pin functions and the PAYG features.

Key product features & similarities

Key features are listed below, yet these new VE.Can SmartSolar MPPT is also very similar to the existing range of SmartSolar Chargers with a VE.Direct port; in that the hardware design is based on that reliable and proven range, they can be configured with the VictronConnect app and they support all the exact same charger settings and options.

  • Ultra-fast Maximum Power Point Tracking (MPPT)
  • Advanced Maximum Power Point Detection in case of partial shading condition
  • Outstanding conversion efficiency
  • Flexible charge algorithm
  • Extensive electronic protection
  • Bluetooth Smart built-in
  • Internal temperature sensor and optional Smart Battery Sense

  • Optional: SmartSolar pluggable LCD display

To read more about the features listed above, see the product page and PDF datasheet. The downloads section in that page includes all the usual certificates, product dimensions, photos, manuals and system schematics too.


EnGo – Smart Solar Street light pole is made by   EnGoPlanet ,the  sustainable solar lighting experts   recently launched a stylish new street light pole product which can even be retrofitted.The attachable design is of a solar cylinder module which can be quickly and easily mounted on any suitable pole for easy installation and disassembly.

Using 6 slim solar panels, with a solar cell efficiency of up to 21.2%, fixed to a hexagonal frame, ensures that half of them will face sun light at any time of the day.

The off-vertical cluster arrangement of the panels makes them less vulnerable to high-winds, less likely to accumulated dust and grime, and easier to clean.

The energy is harvested by a Victron SmartSolar MPPT 75-15. Bluetooth enabled, SmartSolar MPPTs include features which protect the battery from being too deeply drained, and have intelligent dynamic charge algorithms which work with the seasons to ensure the battery will at least periodically be returned to 100% charge.

EnGoPlanet use their own high-quality Lithium batteries, making the unit suitable for off-grid applications where night lighting is required. EnGo – Smart Solar Street light pole can also be used where a grid connection is present – in which case the units will run from their own batteries except where long-continued spells of poor weather require a power supplement to be drawn from the grid. This option is recommended for locations which are often cloudy, or shaded.

Alternatively, grid connected poles can be supplied without battery. Energy produced by the panels will be sent directly to the grid. Savings of up to 80% are possible.

EnGo – Smart Solar Street light pole  installations are also able to collect valuable environmental data which can be interrogated online. Other applications for the poles are for uses such as CCTV, sensors, wifi hotspots, and even phone charging points.

At Nocheski, we  look forward to installing  EnGo – Smart Solar Street light pole  soon

In the dark of night, students in a rural village in Ghana huddle around a kerosene lamp to complete their homework. Others shine flashlights to illuminate textbooks. The lack of electricity, nonetheless computers, dimmed the prospects of a bright future for students in the village of Kpantarigo. This was until Francis Abugbilla, a second-year doctoral student at the Henry M. Jackson School of International Studies at the University of Washington in Seattle, brought electricity to them in the form of solar power.

“The world is technologically-driven. I want to empower the children in my community by giving them a quality education,” he said. “I don’t want the children in my village [of Kpantarigo] to lag behind the world.”

Even though his village of over 1,500 had no electricity, computers, schools or clinics, he knew from his own experience that education is the impetus for change.

Making education matter
Born and raised in a small farming community, Abugbilla worked as a shepherd and began his formal education at 12. He was determined to excel. He walked nearly two hours a day to and from the elementary school in another village. The money his family scraped together paid for the kerosene to light the lamp for his studies.

“I was economically disadvantaged,” Abugbilla said. “Education was the key to change my family’s situation and my community.”

At 17, he participated in a French quiz competition in the regional capital of Bolgatanga. This day changed his life: It was the first time he saw a computer.

“At first, I thought it was a TV because of the desktop monitor,” Abugbilla laughed. “I needed to know how it worked and how I could use it.”

Later in high school, he looked over the shoulders of his classmates. He was mesmerized as they pounded keys and information magically appeared on the screen. He wasn’t confident enough to try. Until his instructor publicly shamed him.

“He said why can’t you do the basic things on a computer,” Abugbilla recalled. “My self-esteem was quite low.”

Determined to prove his instructor wrong, Abugbilla practiced typing with the help of a friend. Not long after, he bought his own Hewlett-Packard laptop as part of a scholarship he earned for his studies.

Becoming a global steward
Abugbilla excelled in his undergraduate studies at the University of Cape Coast, Ghana, where he earned a bachelor’s of education in French honors degree with a minor in English. But he had his sights on coming to America. He applied to the University of Arizona, Tucson and received a full-ride scholarship.

Francis Abugbilla

Francis Abugbilla, a Jackson School doctoral candidate, shares solar power with students in Ghana. Pictured is Francis giving a solar lamp to one of three winners of a global affairs competition that he initiated, September 2018.

As one of five to graduate from college in his village and the only one to obtain a master’s degree, Abugbilla was determined to climb the highest rung of education.

After completing his master’s degree in French, he applied for doctoral programs at 10 universities including the University of Washington’s Henry M. Jackson School of International Studies.

He received six acceptances with four full-ride scholarships. But the UW’s Jackson School stood amongst the crowd.

“I chose the Jackson School because of the accelerated nature of the program. It is not like the traditional doctoral program. I wanted to experience academia and the practical side of the policy world,” he said.

Abugbilla also received the Henry M. Jackson Doctoral Fellowship, funded by the Henry M. Jackson Foundation, that annually supports a deserving doctoral student with promising potential.

Finding a meaningful solution
Despite all his accomplishments, Abugbilla didn’t forget about the young people in his village.

“I had this idea of bringing electricity to my village through solar panels,” he said. “It was this daunting task. I didn’t know who to reach out to, where to turn, how would I fund this?”

Abugbilla shares a Ghanaian proverb: “The gods that look for yams for a child in the forest, will look for a hoe for digging the yams.” Where there is a vision, there is a provision, he explained.

In 2018, he found that chance thanks to the UW Marcy Migdal Fund for Educational Equality, a $1,000 fund supporting exceptional students engaged in finding meaningful solutions to global problems. With the support, Abugbilla installed a solar panel in the village school, allowing teachers to prepare lessons and students to have computer lessons and return to the school in the evening to do their homework. He also initiated an annual global studies competition in the school.The equipment installed include the Victron Energy Phoenix Inverter VE.Direct 500VA and  Victron Energy BlueSolar MPPT 75/15 

The Marcy Migdal fund is administered by the Center for Global Studies, which is housed at the Jackson School and is also a U.S. Department of Education National Resource Center. Students from all three campuses are encouraged to apply for the fellowship in February, with awardees announced in June.

Joel Migdal, professor of international studies who set up the Migdal fund in his late wife’s name said: “I couldn’t think of a project that my late wife, Marcy, who was an educator and social justice activist, would have found more meaningful than that of Francis’s. It brought tears to my eyes.”

Abugbilla continues to fundraise on GoFundMe to expand the solar panel project. He said he has been overwhelmed by the support he received from UW students, professors and others in the community.

“The Marcy Migdal fund was the tool to get me to dig the yam,” Abugbilla beamed. “It was the opportunity that opened more opportunities for me.” Tamara Leonard, Managing Director of the Center for Global Studies, added that the project exemplifies the kind of work that the Fund is intended to support.

Teaching others at UW and beyond
Shortly after initiating his solar power project, Abugbilla was invited to and participated in the Clinton Global Initiative University Annual Conference at the University of Chicago, an event honoring student leaders dedicated to addressing pressing challenges in the world. He also recently served as the keynote speaker for the 2019 Africa Now Youth Leadership Conference, an organization based in Seattle dedicated to inspiring African youth. In June 2019, he will attend the Global Youth Advancement Summit at the Michigan State University to talk about his solar power project.

Thanks in part to support from Carnegie Corporation of New York, in winter 2020 Abugbilla will help teach a course in the Donald C. Hellmann Task Force Program, an experiential learning capstone for undergraduate international studies majors. The Task Force, on energy interventions in Sub-Saharan Africa, will be led by Danny Hoffman, a professor in anthropology at the UW.

While Abugbilla plans on continuing his research at the Jackson School with a focus on peace, violence and security, his heart is still in Ghana.

“The goal is to electrify the schools  with solar power and then scale it up to the entire community,” he said. “It is important that people take their destiny into their own hands and effect the needed change in their lives. I want to spur them into thinking innovatively and outside the box.”

As just one of five in his village and in his family to graduate from college, and the only one to earn a master’s degree, Abugbilla is well on his way to propelling his community with solar power and the world forward.

Intersolar Europe 2019 is almost upon us and will be held at Neue Messe München from May 15-17, 2019.

As ever Victron Energy will be exhibiting. Our stand this year is number B2.480, where many new and updated products will be on display. Four key new products and one new product range are:

  • EasySolar-II 48/3000/35-32 MPPT 250/70 GX
  • MultiPlus-II 48/3000/35-32 230V GX
  • MultiPlus-II 48/5000/70-50 230V
  • Inverter RS 48/6000 230V Smart Solar
  • SmartSolar MPPT VE.Can range

These new products will be launched at Intersolar, however in this preview blog we can delve into a little more detail and compare the new models above with previous models where appropriate.

EasySolar-II 48/3000/35-32 MPPT 250/70 GX

Building on the existing EasySolar (which contains a MultiPlus Inverter/Charger and BlueSolar MPPT Solar Charge controller) this new model has a number of improved features and brings other welcome changes.

The EasySolar-II 3000VA GX (when compared to the earlier EasySolar) is based upon the Multiplus-II, giving the whole unit a more compact and modern design, along with improved standby power efficiency, reduced weight and volume.

The GX suffix indicates that there is a GX device for control and monitoring built-in. A GX device is usually a standalone device such as a Color Control GX, Venus GX, Octo GX or a CANvu GX – but in this instance it is a new integrated GX device, which is already connected to the internal Multiplus-II and MPPT charge controller.

In addition there is a small two line display showing what the unit is doing, and if relevant it can also show a detailed error code  – no more counting blinking LEDs!

The EasySolar-II 3000VA GX allows connection to CAN-bus battery management systems, the VRM remote data monitoring portal via Ethernet or built-in WiFi, enables ESS functionality, and much more.

Another update is the AC and DC rated circuit breaker protection is no longer supplied. This change is based on feedback from our customers who are now able to connect the EasySolar-II GX to their own AC and DC fuses or circuit protection – in other words that which is best suited to a particular application and any regional requirements.

The integral MPPT has had the input voltage increased from 150V to 250V, giving greater flexibility when choosing solar panel configurations. In addition, because the MPPT is Victron Smart, there’s all the usual VictronConnect App functionality people have come to expect from Smart enabled products.

If paralleling and using three phase with the EasySolar-II 3000VA GX, there can only be one GX device in such a system. Indeed one GX device is enough and therefore it does not make sense to buy three of the EasySolar-II 3000VA GXs and put them in a three phase installation. Instead what you do is buy one and then buy two normal MultiPlus-IIs with the same rating.

MultiPlus-II 48/3000/35-32 230V GX

This model is the existing MultiPlus-II 3000, with the addition of built-in GX features. It has all the advantages that you’ve come to expect from GX devices. We’ll keep both products in stock after intersolar Europe 2019.

Like the EasySolar-II 3000VA GX there is a small two line display showing what the unit is doing, and if relevant it can also show a detailed error code  – no more counting blinking LEDs!

Building a split- or three-phase system, or parallel system, with the MultiPlus-II GX models can be done. But there can only be one GX device in such a system. Indeed one GX device is enough and therefore it does not make sense to buy three of the MultiPlus-II 3000VA GXs and put them in a three phase installation. Instead what you do is buy one and then buy two normal MultiPlus-IIs with the same rating.

Another option is of course to use multiple normal MultiPlus-IIs, and then choose a GX device to your liking.

Below you can see the plethora of available connection options available on the GX version. Click the image to enlarge it.

MultiPlus-II 48/5000/70-50 230V

This new MultiPlus-II is simply a larger version of the existing 3000 version. See the product page and choose the datasheet to compare the new MultiPlus-II 48/5000/70-50 to the MultiPlus-II 48/3000/35-32.

Inverter RS 48/6000 230V Smart Solar

Yet another exciting new product, Victron Smart too.

Here are some key features of the RS 6000:

  • Built-in solar charge controller with 450V max PV input. Previously the highest max PV voltage of Victron Energy products was 250V. PV specification limits are 450V, 18A in, 4000Wp
  • Victron’s first all in one inverter+solar charge controller
  • HF inverter – a first for Victron Energy
  • Excellent voltage stability
  • Handy 4 x 20 character display display

The image below shows the bottom cover removed, to reveal various connections which include 1 x VE.Direct and 2 x VE.Can connections. Click the image to enlarge it.

Note: The Inverter RS 6000 cannot be configured for parallel operation nor three phase at present.

SmartSolar MPPT VE.Can

Last in the list of new products presented today is the SmartSolar MPPT VE.Can series.

There will be a series of 150V models available, as well as 250V. More detailed news will be shared in a future blog post after Intersolar Europe 2019 .

More information, pricing and availability

More technical information will be made available in the coming days and weeks: product pages, datasheets, and other documentation is being finished and made available on our website.

Conclusion

As is often the case Intersolar  Europe 2019 serves as a launchpad for many new Victron Energy products. That doesn’t mean other new products aren’t released throughout the year – it’s simply that Intersolar Europe 2019 is one of the best places to see, learn and try the latest Victron products.

Oh! – And of course there’s Victron’s infamous Intersolar Stand Party to attend…
