1) If it draws 12 amps at 120 Volts (I don't know for sure just using your numbers), that's 1440 Watts and to allow for inefficiency and heat losses etc. I sure wouldn't trust a 1500 watt Inverter to do the job long term, Id consider a bare minimum 2000 Watt OR MORE, which might possibly (subject to surge and duty cycle and actual capacity) work. As an example one Inverter I'm currently using has a rating of 2000 Watts Continuous and 4000 Watts Surge
ALSO a motors initial surge start up current may be 3 to 5 times its run current, so an Inverter would have to have sufficient short term surge capacity to get the motor started.
2) If an Inverter were to supply lets use that 12 amps of 120 VAC, that means it would draw something like 11 x 12 or 132 Amps from a 12 Volt DC battery, so you have to have enough battery capacity and/or it being charged via say the trucks alternator PLUS big enough cables from the battery to the Inverter.
Not having any specs or data Id venture a pure GUESS a 2000 Watt Continuous, 4000 Watt Surge rated Inverter just might??? possibly do the job (while Id feel better if it were bigger) and remember you have to have enough battery and/or it being charged so you don't discharge the battery
BOTTOM LINE 2000 Watt MAYBE??
NOTE have you looked into ViAir portable 12 VDC compressors ?? They are popular in the RV community NO INVERTER NEEDED !!!!!
Its electrical so you should get plenty of opinions

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
