Each of the 6 volt batteries is 220 amp-hours, when connected in series you get 220 amp-hours. The effective amp-hours is from the fact you should not discharge standard lead acid batteries more then 50% leaving only 110 amp-hours for your use. If you are using generator to charge batteries you can only get back to about 80% charge with reasonable generator run times leaving you with only 66 effective amp-hours.
Of course these effective amp-hours can be extended if you run generator longer or are willing to sacrifice battery life with deeper discharges.

We are running with 2 6-volt batterys for the house bank, about 220 amp-hours giving about 110 usable.
Pardon me stepping in here for info. I am beginning a study of solar to get more in depth with what I already know and to study other peoples set ups. I am particularly interested in the operation of the smaller set ups such as yours.
When you say you have a house bank of 220 amp hours, are your batteries 110Amp hour rating?
When two 110 amp hour batteries are connected in series, you get the 12v increase but the amp hour stays the same at 110 amp hour.
thanks for any help.

Dan,
Your post suggests that an important component for a full battery charge is time. This makes me think that solar is very well suited to keeping the batteries up, as they produce energy for many hours each day. Otherwise in order to top up the batteries properly you would need to plug the coach into grid power, run the generator, have wind or squirrel-cage power running for a few hours each day. Wind and squirrels are not to be relied on, the Onan is stinky, noisy, and expensive, and if you've got the grid, well then, you are not boondocking.
The length of time it takes to fully top up the batteries is not something I had considered.

I do carry my Kipor around with me and it is so small, quiet and unobtrusive that I have no qualms about using it to top off the batteries when nature doesn't do the job.
