I’m planning to install a new charger/inverter in my boat, with future plans to upgrade to a lithium house bank.
Currently, I have two 120V 30A shore power cords feeding my AC panel — AC1 and AC2 are completely separate. The DC system is also split, with DC1 coming from starter battery #1 and DC2 from starter battery #2.
My old charger (powered from a breaker on AC1) needs replacing, and I’d like the new inverter/charger to power both AC1 and AC2 when shore power or the generator isn’t connected.
Has anyone set up a similar system? Any examples or wiring approaches would be appreciated.
If you have a generator as well as the shore powwer connector, then look at the Quatro, as it will avoid an external transfer switch, and the issue of changing the max draw current from the AC source. Also, do not forget to fit an isolating transformer to the shore power cable - neither the Multiplus2 or the quatro are galvanically isolated (as far as I’m aware). If the isolating transformer is of the 120-0-120 type, then the charging can be split, even on a single leg of 120v.
