If you tie your alternator output to your charger output to share an isolator, you are braver than I am.
Is that statement still correct if the AC charger has the capability of charging up to 3 banks? Like the Xantrax Truecharge 40?
I should have been clearer:
If you tie your alternator output to your charger output to share an isolator ISOLATED FROM THE BATTERY, you are braver than I am. The battery absorbs any voltage spikes that could cause damage. They should go through the isolator and be absorbed indirectly, but I don''t tempt fate.
The drawings are correct representations of what I was talking about. Reading the Xantrex install manual, it appears the drawing with two isolators and the one wiht the Xantrex are electrically the same, except that the Xantrex has a 40-amp 3 port isolator hidden inside the housing,
