Ground relay causes generator overload

I’ve found out that the ground relay of the EasySolar 12/1600 causes the generator to go into overload as soon as PowerAssist kicks in.

If I switch one of the two off, the problem disappears.

Does anyone know of a solution? Putting a load on the generator’s second output helps too, but that’s not a permanent solution.

The ground relay should not be active when there is a grid/generator source connected. The relay should disconnect when the primary relay closes in normal operation this is to be compliant with many grid codes that the neutral ground bonding is done at source

I don’t understand it myself either.

Could it be that the relay switches on when PowerAssist needs to kick in? Could that then cause a sort of short circuit that the generator can’t handle?
