fish90909: Looks the box with the fan is an inverter or charger right above that is the on/off switch. Continue up the looks like a solenoid then a voltage regulator. Next it’s just have a small bus then a breaker. Some of these are just guess with out being about to look at in person.
Mrsjonsmith: Thanks yeah I looked up the model number on that box, I think it converts ac to dc to re charge the batteries or at least run the dc lights and outlets when on shore power.
I’m looking to incorporate a large inverter to get ac from the batteries. Not sure if they make inverters that do both.
