1512 inverter charger, if it's working and charging the batteries
And you have no 12v power in the RV , lights , water pump etc
Battery disconnect is off ? Or bad,
Main fuse at dc distribution fuse center is out ?
What do you mean power to batteries from outside source?
I can explain it to you.
But I Can Not understand it for you !
