Asked to attend to LED lights that would glow when not switched on.
On the DB there are 2 Neutral bars. They were not connected. After connecting them the glowing issue went away.
The DB wasn't partitioned for AC and DC but the sytove circuit breaker was powered directly from the Main Isolator (bypassing the earth leakage)
After sorting the neutrals out the inverter throws an error and alarm when coming out of loadshedding. When only on AC or only on DC the thing is fine. It's when crossing over.
Error code is F18 - AC overrun
Checking the manual there is a L, N and a "PE" cable.
Existing wiring is L and N from the Main switch to the Inverter, and then a blue and yellow connected to the power in on the Earth leakage - Blue to N and Yellow to Live.
I'm sure this is incorrect but don't know enough about inverters.
Can anyone assist?
