ive got a single phase ac motor that runs on 110V and i'd like to run it on a 12v dc source. basically its a transfer pump for a school bus that runs on vegetable oil, and we currently have to find an outlet to plug the pump into every time we go behind restaurants to fill up our tank. id like to just hook it up to the bus battery but don't know exactly how to do so. we have a 5000 watt inverter which oddly doesn't work, it can't handle the draw from the pump. there are six 12v batteries wired in parallel that the inverter is hooked up to but of course i'd prefer to just wire those batteries somehow directly to the pump. there is more info on the pump here http://transfer.tuthill.com/Products/OilPumps/LTKoilmore.asp and LP50P36Q115 is the model number. any thoughts? thanks!
