Brandon Williams Posted May 28, 2023 Share Posted May 28, 2023 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 Quote Link to comment Share on other sites More sharing options...

Regards I suggest if you have a multimeter to measure the voltage between neutral and earth on the Eskom side. It should not the higher than 2 Volts TaliaB 1 Quote Link to comment Share on other sites More sharing options...
Brandon Williams Posted May 29, 2023 Author Share Posted May 29, 2023 Hi Antonio, thanks for the suggestion. I see that I have 98 Volts between Neutral and Earth. I imagine I should add bonding at my main DB box to fix this? Quote Link to comment Share on other sites More sharing options...
