May be a stupid question but

Would have a large battery bank cover your power usage when you have roof panels that are less than what you need if you only use more than you make occassionally? For example, you have a washer that eats power but you do a load or two a week and the rest of the time you have your fridge, basic pulling power only. If you make enough solar to cover basics plus some to recharge, would having the extra batteries do the trick? Also, can you charge the batteries from shore power if you are low and camping out?

Yeah what you want is a three stage converter charger hooked up to your battery bank for when you're on shore or a generator. I might put a solar panel on top but it will only serve me on the road or in my parking lot to sort of trickle charge my batteries. We always camp in the shade to be a heat. I'll be fully recharging them with a converter and by generator for a couple hours.
