March 24, 20197 yr Hi all I have a 3 phase system and trying to install a Mecer 3Kva inverter( + 2 x 12v 200ah batteries). My electrician has tried a few configurations and just cannot get it to work.When I turn my Changeover switch to inverter mode(switch position 2) , the earth leakage on the main DB drops IF eskom power is on, but if Eskom power is OFF then the earth leakage stays on and my batteries power the phase.When I turn my changeover to Eskom supply (Position 1) , earth leakage stays up and I'm getting supply from eskom.Problem is , I've got to go manually change the switch during loadshedding.Can the experts please have a look at the way it is connected and advise.
