Why go solar?
Why go solar if generator/propane is still a must? After looking seriously at fitting rv (when we get it) with solar I am beginning to realize that solar cant keep up with what I want it to do. I want...

IMO GordonThree has a serious problem with his monitoring system not telling him the truth.
We know that 1550w approx. "goes with" about 75 amps output with a non-PF corrected charger. We know that a 100 amp PF corrected charger pulls about 1900VA. We assume this charger is PF corrected and is pulling about 1550, so output amps must be somewhere under 100,
1550/1900 x 100 = about 82 amps. If you do the calculation I did with 82 amps instead of 100, it all takes more time out of that 4.5 hours and becomes even more impossible.
I don't understand what is going on here, but it appears to me that the set-up is not giving GordonThree the information he needs to properly look after his battery bank.
It looks very much like the 800AH bank has been undercharged regularly and is sulfated. In use, it may perform "just fine" when not being pressed hard where a smaller bank would do the job just fine too. It will also take less time to recharge since it is now at a lower capacity
Since 800AH worth of batteries must cost quite a bit, IMO the whole situation needs to be cross-checked with as many different measurements as possible and get to the truth of what is really happening.
Do a serious "recovery" of those batteries (if it is not too late) and arrange for a proper monitoring system that tells the truth. Or else be ready to buy new batteries more often.
