Ok, let’s talk about a solar PV system and why setting up a solar PV system in South Africa is a good idea. We will demystify some information around a solar PV system set up and, specifically, refer to the RCT Axpert 5K MK2.

We recommend a simple RCT Axpert 5K MK2 as you do need a little bit of extra capacity to handle surge loads for things like: general appliances and basics like personal computers.  A really simple installation would be to wire this up to your existing DB board,  then split the board, one off-grid and one on-grid connected or, generator power auto restart.  This is easy enough to set up with a qualified electrician, who can connect through prepaid DB boards as well.

If you’re in South Africa, the RCT Axpert 5K is a lifesaver

Here in South Africa, we have an additional complication called load shedding.  Having a RCT Axpert 5K inverter and MPPT solar charger and battery charger to offer uninterruptible power supply connecting system allows you to have a seamless lifestyle.  Another added advantage? You may have noticed that the price of electricity continues to go up – on average, we are seeing price increases of up to 25% per year in South Africa.

RCT AXPERT 5K information and specifications

Pure Sine Wave Technology will keep your voltage steady

That means the payback on your RCT Axpert 5K mk2 pure sine wave inverter becomes better and better! Before you start, we recommend buying a consumer meter to understand how much electricity you will be using, what appliances/devices you will need to cover and then, calculate your acceptable input voltage based on multiple applications.

I've had some major computer (RAM) problems that I was convinced were unfixable. Luckily, I found this company and not only did they fix my issue's but also made my laptop run faster than ever before. Plus dealing with the staff is like having access to a solid IT company. Friendly, professional, helpful, and knowledgeable about the products and their work. Would definitely recommend!
