The Kruger National Park is home to a third of the world’s remaining Rhino – a fact which makes the park attractive to poachers who kill Rhino just for their horns.Rhino Poaching Surveillance in the Kruger National Park

In order to try to prevent the Rhino from becoming extinct – Park Rangers have to be constantly on the lookout for poachers in a wilderness which extends to 2 million hectares. That’s an area equivalent to a box whose sides measure 140km/90miles – you can’t be everywhere at once, so the Rangers have installed some discreet technology to help.

Saving the Rhino is a race against time because the growth in poaching has been alarming: In 2007, 13 Rhino were poached in South Africa …by 2014 that figure had increased 9000% –  1215 animals were illegally slaughtered in that year alone.

Powdered Rhino horn has become more valuable than cocaine – fuelled by the misguided belief, particularly in the East, that it has medicinal value. When prices rose recently, Rhino became a target-interest of international organised crime – turning what was then localised illegal activity into something of global industry.

In order to maximise their policing, Kruger National Park Rangers have set up a number of radar detection systems, strategically installed to offer wide area surveillance, both day and night. Three or four units allow them to cover half the park area. The radar detects movement and plots it on a map. Remotely operated camera’s allow the operators to distinguish between  ‘Animal’ and ‘Human’ movement. Suspicious activity is then intercepted by truck or helicopter.

Financed mainly by charitable donations the surveillance installations are highly mobile, frequently moved, and can be packed for deployment by truck – or even slung under a helicopter and flown-in to new surveillance sites.

These mobile installations need reliable off-grid power source – for which Lithium battery specialist BlueNova located in Cape Town led the system design. Lithium Batteries are an ideal solution to frequently-relocated installations – amp for amp they’re almost 80% smaller and lighter than their Lead/Acid equivalents. And amongst a topography of scrub and boulder, PV panels offer discreet power-generation. They do not impinge on the visual amenity which is so important to wildlife tourists on safari; and they remain undetected by would-be poachers.

The power plant features 26V-8kWh BlueNova Lithium Ferro Phosphate battery (LiFePO4)

24V 3kVA Victron Multiplus

2 x BlueSolar Victron MPPTs  Solar Chargers to regulate the six-panel PV array.

 

Currently, three Rhino’s are killed illegally every day. At that rate the animals will soon face extinction. All that can be done to slow the decline should be done. Against armed poachers, the Kruger National Park Rangers are carrying-out a dangerous job with utter commitment to conservation – this technology helps them reduce the slaughter.


When it comes to the buying decision for solar inverters, some buyers might be inclined to only look at pricing and spec sheets. While these are certainly buying criteria that should not be neglected, it is just a small portion of the bigger picture that needs to be looked at when choosing an inverter brand – because an inverter is more than what’s in the box.But why should you even consider Fronius Solar inverter?

As the solar inverter industry is becoming more commodified every year, inverter spec sheets are starting to look a lot more similar. Many inverter capabilities are driven by the same market requests and NEC code regulations, making features and pricing very similar across all inverter brands in the market. Therefore, a buyer could think that the only thing to look at is the price tag. However, it’s crucial to actually look past the spec sheet and the initial purchase price. When picking an inverter, you not only chose a piece of equipment, you are choosing a partner to work with for the next 20+ years. Thus, you might want to look into more than just “the box” and its price.

So what specific buying criteria is there beyond specs and price? The inverter is a critical component of a solar system, as it is not just responsible for DC to AC conversion, but also for the safety of a system, maximum power point tracking, grid interconnection and system monitoring. It is obvious that the inverter and its performance have a big impact on a system’s Levelized Cost of Energy (LCOE) and profitability – inverter uptime, operation & maintenance (O&M) programs and warranty matter in that regard, and this is where the company behind the inverter plays a crucial role.

When choosing an inverter partner for the long term, it is crucial that this partner is around beyond the lifetime of a system. Therefore, financial stability and bankability, as well as a global footprint with a local support infrastructure are key aspects to look at. There is no doubt that the fairly fragmented inverter market will see further consolidation, given the ongoing price pressure. This increases the risk of certain manufacturers going out of business and leaving both installers and system owners in the lurch.

Furthermore, an easy to reach manufacturer support hotline and personal, long-lasting relationships on manufacturer’s level help installers through the entire process from designing systems to after-sales service for 20+ years – ensuring uptime and quick service. Since all power electronics can fail at some point, customer-friendly warranty terms and an easy RMA process are making a big difference. Power electronics manufacturers from advanced industries even offer spare part kits among certifications for contractors to conduct repairs cost-effectively in the field and within one truck-roll – a big impact on the profitability of a system.

All these aspects make a big difference and cannot be found on a spec sheet or on the price tag. Make a smart choice. Do not just look at the spec sheet and the price tag, when picking your  solar inverter. It’s a decision that will impact you over the next 20+ years and you want to be sure that your considerations are aimed at this period of time too.That is why Fronius solar inverters is a great choice.
