What I want to accomplish is an electrical system that will allow me to run some outlets (phone chargers, computers etc, no appliances) and the AC off the bus batteries and alternator (with a inverter) while the bus is running and then power all that same stuff with the generator when not running the bus.
My plan was to run a cord from the generator and a cord from the bus batteries to a central box between my seats in the bus. These would run into a selector switch where I could turn it to Battery power, generator power, plug in 50amp power, and an off switch/selector. Not sure if a 4 way selector exist but at least the 2 or 3 would be nice.
My question is, am I going to need a separate battery bank while running the AC and outlets while using the bus batteries or could I hook directly into the 3 existing batteries used to start the bus. Will a 15,000btu heatpump and some small phone chargers run the batteries dead (over say 15 hours) or will the alternator be able to keep up?
I bought a EU7000is Honda generator,
super awesome generator. Been using it on the road and it is beastly. Ran a refrigerated beer truck, 4 industrial fans, and a full PA for a band all at the same time. I think this thing could run a neighborhood if it needed to, and needless to say will be more than enough got the #BRAGeorgia bus. I plan to weld some mounts to the bottom of the bus and mount it there. It is ~ 261lbs and will need significant amount of supports holding it.
I also bought this 15K btu heat pump
, as the bus is a sweat box here in the summer and AC is needed.
Advice on how to set this up, inverters to buy or selector switches would be GREATLY appreciated.
