Hi SkiMore,

Ah, but...after 85% state of charge acceptance rate drops to about 12.5 amps per 100 amp-hours of storage (at 12 volts). Thus generator run time becomes excessive. At 95% it is about 3 amps per 100 amp-hours.

There are 120 volt led bulbs but I'm not sure if they like inverters. What inverter do you have?

Unfortunately if you wish the battery bank to last, of the 5500 watts only 2750 should be used (i.e. 50%).

You speak of eight batteries. What are they? How many amp-hours?

So, even with two batteries I wouldn't get past 90% charge unless I burned a lot of gas.

How are people in RVs without solar effectively charging their batteries? Are they dumping massive amounts of energy into them while connected to the wall? Do people with TTs or FWs run extra heavy wires from the alternator all the way back?

I forgot about the 50% thing. Even at 2750 watts that is a huge amount of power especially if I had a 300watt panel charging it while I was there. It's more than I would know what to do with at the cabin. I guess I could buy an induction hot plate and save the propane and get a 5000BTU AC unit. Sounds like I won't need so many batteries when it comes time to replace them.

Thanks for mentioning the possible issue with 120V LED bulbs and some inverters. I'd hate to buy a bunch of expensive bulbs and have them not work or fail early. Do CFL bulbs have the same problem?

The inverter is triplite PV-2400 2400watt 24V input.

We have 8 NAPA 8144 batteries. They are probably 5 years old. I'm having a problem finding the AH spec. It says 115MINS@75A on them. Does that mean it is a 144AH?
