Gerald,
That makes sense, it has both. The other question I have is that I cant get the charger side of the inverter to start since we plugged into the pedestal at the campground. When Iturn off/on charger I hear an inter "clunk" sound. The LED lights on the panel show 12v and the inverter button blinks green. The batteries show only 10.5 volts on command center. When I start the rig the alternator charges at 14.5 volts and battery charges to 12.8 volts. When I plug into our shore power, battery voltage starts to drop immediately and settles back at 10.5 volts.
Thanks
