more batteries mean less amps charge PER battery from the solar, but it also means less ampHrs pulled from each batttery while discharging, i do not expect my USE amount to change as we are NOT doing ultra conservation right now, this is OUR HOME and we use power accordingly as needed to be comfortable, I have florescent lighting NOT LED and expect to stay that way for the immediate future, compact FL for 120v fixtures and 12v FL for the ceiling fixtures, we will not be using more OR less with more batteries or more solar, only the load will be spread and possibly OCCASIONALLY extend the NON-op time period being generator runs, but then the runtime will have to be extended to restore the larger battery bank, its all a matter of trade off's
Yes the. Onan is 6.5kw
but i try NOT to run "that one" too much and prefer to run the 3k champion
I will run the onan when raining, or when i need both A/C units or the A/C and something else
