Hello All

Our solar system consisting of 2 x 6Kw inverters and 4 x 5.1kwh batteries set up in a slave/master config has developed a rather odd issue. The MCB connecting 2 of the batteries to one inverter randomly trips. I can immediately reset the MCB without issue until it randomly trips the next time. This is usually around once a day and I think occurs when the batteries are discharging. We use the batteries to load shift as we are on Octopus Cosy having 2 ASHPs.

Any ideas ? The system is Skyline made by CYG, who are helpfully no longer trading in the UK.

Cheers

Alan
