Below are three pieces of equipment that I’m considering for a solar power system in my bus.
My real power needs are in the 4500 Whr range. I want a bunch of head room above the 4500 range so I can run a space heater in the winter and lots of fans, even off-set some time on my generator in the heat of summer. I’ve been running a killawatt for about a year.
No solar panels planned at this time(have room for 6). Will be charging the battery bank from shore power and generator until I buy panels in late spring 2020.
Am concerned with mismatched components and am wondering how long it will take for the 24v 400Ah battery bank to charge to up to 90% with this 80A charger.
Here’s the list: 1 each - 2400w Pure Sine Wave Power Inverter; 80A MPPT Solar Charger; DC 24V; AC Output 110V 120V; 60A Utility Charger; 60HZ.
