Sine Wave Inverter

Out of curiosity I ran the aircon in the van , it ran for fifteen minutes before cutting out for low battery , on the road when stopping for a cuppa could do toast , microwave and boil the kettle but alas I let the unit go with the van when I sold it .

Do the numbers. There is a 20 fold amp draw at 12v to 240v, and i am sure the aircon draws a heap, so not surprised your unit went out on low voltage, even with the engine running. You would need a fast idle at least I suspect.

Yeah I know , only two batteries , one not so good , and that power hungry aircon was always going to trip the inverter .
I only did it to see if the inverter could handle the load , which it did in spades .
Did put brand new gel cell batteries in it to sell it .

On start up, without soft start technology, electric motors can eat up to 8 times their normal running current.
