Onboard, i have a split phase generator (which i did no know) and i recently installed a Multiplus II 24/3000. The generator zero is connected to the hull, since i only use 230v. There is 120v between L1 and N and L2 and N there is 230v between L1 and L2.
Here in NL the shore connection is 230v ac single phase. On the output of the victron i have a GFCI breaker installed and 4 breakers after the GFCI.
The Shore connection is connected to a 5000Va isolation transformer. secondary is connected to a high current three way switch. (L1 & N) in the isolation transformer secondary side N is connected to the hull. There is no shore ground
When i put the switch on 1 the shore is connected to the Victron input. (Single Phase)
on imput 2 of the switch i would like to connect L1 & L2 of the generator for a 240v input
When i put the swich in pos 2 the generator is connected to the victron input (Split phase L1 & L2)
Can his be done? (Safe) so i can use the Victron and charge the lifepo4 battery from the genset when sailing? And will my GDCI still work.
The victron Neutral relais need to be disabled i think, otherwise 115v will be on the victron casing when genset in running.
When disabling ground relay using 230v from battery, there is no closed ground relay which is also a problem. Maby make a external ground relay which connect victron output N to ground when there is no ext power source?
What are my options? I am struggling with this question for some time, and affraid to start my genset at the moment.
