No way to charge the 12v batteries from the alternators as a backup?

My thoughts on that are if underway the gen set is feeding ac voltage and if at dock hooked to shore power. Either way the converter/charger is maintaining the 12v system. if worse came to worse in any case would have more batteries available than fuel.

Where are you located?

12 volt as a subsystem leaves a big question for charging.

If you dont have a 12v alternator then you need a way to keep the 12 volt stuff running wi th h 9i UV running AC.

PM me if your interested in getting it designed correctly.

Theres a lot to be considered. Especially on a tear our where the insurance company will want it up to modern standards.

I appreciate all input, there will be lots of things to work out in the system.
