so I am upgrading the battery in my camper from a 280AH to a 304AH (moved the 280 into the 5th wheel with the other two) and for the last three years I have not plugged it in at home and just let the solar cycle it at a partial charge when not in use. now the wife wants some more creature comforts when camping like 120V appliances and plugs so I am looking at a 2000 watt inverter and wiring a couple more plugs. so I started looking at inverter/chargers and found that renogy makes one for a decent price that in Li mode it will charge to a specific voltage then it will shut off the charge until the batteries hit the bottom voltage. at this point it will turn the charge back on. so there is no charging in between the two voltages. also in custom LI settings you can set the two voltage setpoints to what ever you desire so you could set the upper to 13.6ish V so you can do a top Ballance when it charges up, and the bottom to 12V.
so what I am getting at is if I say, use those two values then set my max voltage in my solar controller to say 13.3V so when actually camping the solar will keep it charged up to 90% max, is this a good idea? or is there some potential issues I am missing?
