Boondocking --- Average AH consumption/day?
I'm going to be adding solar to my 2015 Class C Majestic 28a. I currently have 2 lead acid batteries that state they have 122AH capacity each (from Walmart). I'm trying to figure out if I should add...

Multiple charging sources only affect battery amperage acceptance as voltage rises. Saturation charging means adding more chargers set at the same voltage as the saturation voltage won't yield one more amp. The monster ferroresonant charger is reconnected to provide 29.10 volts. The Trace is set to 30 volts maximum and the voltage regulator on the Lambordini Delco is maxed at 30.
When I put the big charger online it may put out 480 amps and bring voltage to 26.7. The Trace inverter has a charging capacity of 120 amps but not if it is trying to dump into 26.7 volts which is the same as 13.. volts on a six cell system. The Lombardini is air cooled so sometimes I share principal load with the Kubota. This knocks amperage down to less than 300x2 amps (shared). Voltage remains saturated because I hand adjust each charger. Finals are 28.8 volts. Tweaking back from 30. When you reach regulated voltage even at low gravity start points that I deemed as "Saturated Charging" Not recommended for thin plate batteries.
My own rule is the use solar when the highest potential generating power proves to be lower than maximum saturated charging acceptance. For me it means generator charging in the early morning then solar at mid morning to sundown.
