Good day I have a LV 5KVA-48V INVERTER / CHARGER and I'm only installing 1 and running it in single phase. But I'm keep getting this code the manual does not show how to set it in single phase . Also it I'm not getting my solar to charge my battery when it powers on it beeeeeps stay on for a few seconds then peeps screen blinks and repeat with said error code. Any help in this matter would be appreciated thanks
