I have a solar generator I am building/upgrading. I am putting a 2000 watt pure sine inverter, 40 amp MPPT charge controller, and one 4S 12volt 120Ah battery bank inside one pelican case. This will work well for my truck camper, 4H events and similar activities.
I would like to make another battery bank to have more capacity. What would be the cons of building one box with 2P4S 12volt 120Ah cells (total of 240Ah in one box).
I've considered going to a 280Ah cell and just building one bank of 4 cells.
I could wire the generator so the 120Ah bank (inside the pelican case) is not used and we could use the 280 Ah bank exclusively.
I am specifically wondering how this will wear on the 240Ah bank (with 120Ah cells) if I use it in parallel with the internal 120Ah bank.
