Electrical System Planning with Generator
We are looking at a bus that the owners had setup for tailgating. It comes with a 7500w Onan diesel generator tied into the main fuel tank, inverter, electrical panel, and interior and exterior outlets. We want to mainly camp in national/state park campgrounds that usually don't have hookups and have limited hours for generator use. We plan to travel with the bus for road trips once or twice a year, not live in it full time.
There's no doubt the generator could run anything we wanted to plug in and would be easy enough to run for an hour or two mornings/evenings, but how do we size a battery bank for the hours we're not running the generator?
Ideally, we'd like to run a 110v apartment size fridge (we're a family of 5, so we use a fair amount of food), 1-2 burner induction stove, small electric water heater, a few fans, LED lighting, possibly occasional microwave use, and cell phone chargers/possibly a laptop charger without firing up the generator more than once or twice a day. Is that possible on a fairly small system (size recommendations welcome!!), or do we need to look at different appliances/propane setup instead?
