SOLAR PANEL ISOLATOR SWITCH SKIN

Yesterday (23 January) we noticed that the isolator switches are even hotter (rated to 63A at 240V AC), so hot that if you were to hold it for more than 3 seconds, it would most likely burn your skin considerably. Jump forward to 19 January, the electrician has still not come through, we sent a follow up message.

The electrician got back to us that he would come by as soon as he is back from holiday. We then noticed the few next day of full sun that the cables are getting extremely hot, hot enough that the sheathing is able to slip on the copper cable. We bought exact replacements to what was installed, and replaced the destroyed isolator switches and fuses. Thinking he is on holiday we left it and decided to sort it out ourselves. We called and whatsapped the electrician who installed the system with no response on 22 December. We shut down the system and pulled out the switch which was completely destroyed due to arcing. Shortly after that the smell became worse and I noticed what looking like melting on the 1 isolator switch. We replaced it thinking it was a manufacturing defect. 1 of the 30A fuses inline with the solar feed had blown. Suddenly solar power was lost and I investigated further. In December I noticed a burning smell in the garage where the solar system is (isolator switches, batteries, inverters and DB boxes).Īs I was soldering that day, I assumed I accidently burnt something with the soldering iron and just left it. So we've had a solar system for just about a year now.
