    Solar isolator (to distribution board)

    I don't do PV, so not overly familiar with specific regulations. Yesterday I was changing a consumer unit, and the isolator for the PV was adjacent to the consumer unit. Due to needing a bit more space, I had to move this isolator a few cm and noticed it was single pole, switching L only. A...

    Solar iboost not working

    We have a solar iboost which was working fine then suddenly stopped. If you turn it off at the mains and then on again, it says low voltage and heats via solar initially with a high reading then this drops until zero and it states heating off. Amy ideas on what the problem could be? Thanks

    Hello everyone, I have a fairly technical question. I wonder what will happen to the efficiency of the PV system when we shade the bottom of one solar module (HCC) connected in series? Will the performance of the entire string decrease by half because only the top works in this module? Isn't it...
