Hi,
I have gone over old answers but I tried their answers and still have a nuisance tripping RCD.
We upgarded an off grid system from a 12v 3000w 120 Multiplus to a 48v 5000w 50 Multiplus ll.
I also installed an RCD immediately after the Victron which it didn’t have before. The RCD is nuisance tripping under high loads from motors (hoover, washing machine etc).
I removed an unnecessary secondary earth rod from the houses which seemed to stop it, but it began again.
I’ve tested the RCD and it’s functioning correctly.
I’ve upgraded the earth to the earth rod to 16mm and installed an earth on the negative from the battery (it didn’t have this before).
I’m not sure if there is a setting on the Victron I haven’t set correctly or it’s an issue with the electrics which the new RCD as reacted to. The old RCD’s in the house we about 5-10yrs old.
All help is appreciated
Thanks
Rob
