Hi all
I have a system setup on my boat where I have shore power coming in via onboard MCB (16A) and a RCD type C as specified in the Victron instructions. The earths are in separate terminal, so I’m separated from the shore earth. Then wired directly to the AC Input on the Multiplus.
After installation I plugged in the AC from shore and everything was fine but after the first time I disconnected I have a strange phenomenon where I have a RCD trip either in the shore supply system or the one installed before my inverter AC input every time I plug into shore power. At first I thought it was because there were another RCD type C in the shore supply so tried to Bypass the one installed onboard but with the same result.
I found a procedure that worked for connecting to shore AC supply but I does not seem right that I have to go through that every time. The procedure is as follows:
-turn off the main 12V distribution switch
-turn off my multiplus on the front or via remote
-turn off the AC output loads via the AC out MCB/RCD
-Pull my main 12V system fuse (125A) out
-then in able to connect the shore cable, turn the inverter back on, insert the main 12v fuse and reconnect the 12V and 230V loads from the distribution panels internally.
I can’t get my head around why this happens?
anybody have any ideas?
