I fully understand that it is difficult to identify legitimate installers and also, I am sure there are other installers who also try their best to adhere to quality and legislative requirements. It has become hard in the solar industry to compete on price with other installers. Luckily, legislation and standards bodies is trying to address this problem. One initiative was for the establishment of a solar industry ombud who can assist with disputes. AREP (The Association for Renewable Energy Practisioners) of which we subscribe to was party to the establishment of the Ombud's office. To log a dispute, the ombud can be reached at [email protected].

@Modina, would you like to answer the second question too?

The solution to your question is a simple one. Use a shielded cable and ensure that the shield is earthed at the same potential as the system. If I am right, the CT has a ratio of 2000:1, therefore the maximum current in the secondary coil can be calculated and combined with the electrical properties for the UTP cable you use, a simple calculation will show the power loss over the distance using multiple numbers of wires. If calculated correctly, secondary effects such as capacitance in the wire can be ignored.

Please refer to my previous post. We all carry huge responsabilitiy in the comments we make about others. Please find attached a pictures of just two installation we have done recently for customers. Dare I ask whether you recognise the brand and the architecture associated with each and explain the difference between the two on this forum for others to admire your knowledge of PV solutions.

I find it hard to comprehend that there are always a couple of people who spend so much time to prove that others are not to be trusted. Have a look at this article which was published in a local newspaper after we installed a 160kW solar system in the Brits area: Top SA energy company LessWatts switches Brits to solar (mypr.co.za)

I agree, it is way too low. I assue this is something which came out in the short time they have been in the market. In an attempt to limit the influx of repair requests, they have now limited the breaker sizes.
