    I have 2 arrays on 2 SMA inverters. One is 500v single string and the other is paralleled 2 x 300v strings. I have just lost one of my arrays via SMA 2500. It is lit but no power generation. I replaced with spare Steca which would not work as it needs more PV voltage so I had to swop over the...

    Inverter

    Just a quick one before taking the inverter back. Recently we got an 12v to 230v inverter but started getting a shock off the casing. Tested it and around 80v but sometimes up to 120v. Is there something that can be done or is the inverter faulty
