Hello Everyone
I was wondering if anyone has had the same experience with these inverters. I have a Growatt SPF5000ES and get error 51 'Over Current or Surge' when connecting the EARTH from the Eskom supply. I have disconnected everything from the inverter except the batteries, and as soon as I switch on the Eskom power to the inverter it gives me this error. When I disconnect the EARTH from Eskom's side and power it up there is no problem and the inverter works fine.
Regards
