power inverter question

[usmc1217]

I have a rigid 5hp shop vac its specs are: 235 air watts 120 volts and 9amps
Can anyone tell me what kind of inverter to get in order to properly run this vac? I use it about once every two weeks to vacum out my truck.

9 x 120 = amount of continuous watts needed. I would probably get a 1500 watt continuous to be on the safe side. Not sure what the starting wattage would be for the shop vac, but im sure something like a 1500 watt continuous with a 2500 watt surge capacity woul be enough.
