its own battery and a pure sine wave inverter to run the computers for it.. I regularly run a server rack in my Bus. with a GoPower 1500 Pure sine wave inverter.. im using 2 group 31 AGM batteries. and charge the whole mess with the bus running when im driving.. it all works well.. even the switchover when the isolator kicks in when I start the bus doesnt affect the machines.
