Thanks Goodnewsboy and Sailingdog.
I will look into the isolator issue. Thanks for the links.
This is where I am going now.
Without a system level controller for the six charging sources (alternator 1, alternator 2, generator, shore power, solar, wind) I assume that I can only use one charging source at a time. Otherwise, I assume that the alternators will shut down the smart controllers or vice versa.
Main Engine Alternators
The alternators on the main engine are the single wire universal type with built in regulators. To avoid the lazy alternator problem from two regulators charging a common battery set I am considering having one charge the house and the other charge the start batteries.
I found a 5000 watt 220 to 110 coverter with some level of power conditioning. This could feed the 110 AC bus and a couple of smart chargers (one house/one start) that operate when the generator is used and the main engine is off.
Feeds AC bus and smart chargers when shore power is selected.
Probably product specific but these are common add-ons and the integration problems have probably been sorted out.
