i had a 3kva inverter - over 1kw you need to power off the battery direct- bear in mind tho pulling 4amp at 240v ac is around 80amp on the 12v dc side- so your batterys arent gonna last long

I use a flying lead from the outdoor unit supply to a 3 pin extension socket via RCD when on a roof when power is available to the outdoor unit (or adjacent unit).

Never thought about using an inverter in the van as the lengths to the roof may be a little too far

There are small generators, petrol operated and 1000W, just over 1HP is very helpful at operating all our machines.

Its also good for home emergency power brakes.
