- Want to run an electric motor from a petrol generator but the startup load of the motor is too large. Could a car battery supplement the generator to start the motor?

Hi All,

So i am looking to buy a petrol generator to run a 2.2KW electric motor. I was thinking of getting a 3KW model which under normal conditions this should be ok - but on start up I've been told an electrical motor draws 6 to 10 times the normal load, which is way too high for the generator. So I am wondering if I could could hook up as well a car battery on a 12v- 230v invertor?

My logic is when the motor starts it draws on both the generator and battery, then once started only draws on the generator.

Is this possible and how complex would the wiring be? On a sidenote getting a more powerful generator is not feasible as it would require around 18KW which costs thousands!!!

Many thanks,
