i have a question.
i have a skoolie with a 12.5kw generator hanging from it. all of my 120v needs are covered. i want to install a 12v converter, so that i can charge my battery while parked and camping with the generator.
another forum advised me to install a battery bank, inverter, fusing, before i think about adding my rv loads. i do not want an inverter at this time. i do not wish to plug into shore power.
how do you know if the truck can handle the load?
to the vehicle's current load.... i wish to add:
12v water pump
12v macerator pump
12v rv furnace (in the future)
instead of installing a new battery bank and moving all my rv loads off the truck battery, whats wrong with just wiring my 80 amp converter/charger from the genny to the truck battery? that way i can recharge the truck / house battery when the genny is running.
now... my bus uses 2 group 31 batteries for a truck battery (220ah rated)
the gen uses a seperate grp 31 battery (110ah rated) for starting
the 1 gen start battery would be isolated to never drain.
that may not give my the reserve ah i was looking for originally......but it is the set up i commonly see on skoolies.net.
my predicted daily battery use is between 80- 120 ah per day..... normal is the low number, max is the high number.
currently the bus has a 12v fridge running on the truck battery. i currently recharge the battery with an auto 120v battery charger plugged into the outlet of my genny.
of that 80ah load..... the already running fridge is about 60ah (guestimate).
i want to run a hybrid system..... 120v large loads run when cooking, and small 12v loads the rest of the time.
thanks for your help
