I've attached my schematic for my electric plan. The main goal is to be able to run at least one roof AC unit while driving.
I just installed a 320A Leece-Neville 40SI in the bus, so it should be able to keep up with the calculated demand of 142A for one AC unit. The calculation still works out, but both ACs might be pushing it for any serious length of time. My understanding is these big alternators have a much higher duty cycle than regular automotive ones, but I'm not sure it's 100% at max output.
I also want to isolate the starting batteries from the alternator. I assume a 150A battery isolator would work fine? The stock alternator was 150A, so that should be able to handle the remaining bus 12V loads (ECM, lights, blower fan, etc).
Basically everything 120v inside the bus is connected to the main panel and the input to that if fed from a 50A shore power outlet. I am able to pick which power source feeds the main breaker panel by which cord is plugged into the shore outlet. I have one 50A cord for when we are parked at a campsite, one 30A cord to connect to my 3500w generator and the inverter output is wired to a 30A plug. So when I'm driving, the inverter will be plugged into the shore outlet and power everything inside the bus.
I'm going with either four or six 6V golf cart batteries wired in series and parallel to make 12V and either 420Ah or 630Ah.
I do not plan to add solar at this moment.
Does anyone have any suggestions or critiques for this plan? My biggest question is with the battery isolator. Will a solenoid type be sufficient to keep the starting batteries charged while driving? It's a DT466E, so I can't be without power to them.
