Thread: I've gone and done it.

Sounds like you could do it on a Tesla Powerwall 2, only 110kg and 13.5kWh usable capacity...

RRP is $A8000 plus installation costs....

Hmmmm, might have to revert to the waterbed, with ice cubes.
An auxiliary generator was always in the plan.
I have heard of a fellow who has three tonnes of batteries in a similar conversation, he can run two aircon units overnight.
Another option is to run the existing compressor from a small engine, instead of the 360 HP it is currently driven by.

Are you trying to a/c the whole shebang or just your bunk overnight ?

The whole show Paul, it's just a tad over 40 m3.

The Tesla power wall would certainly come into its own in your application Ian.

You could run a generator - and probably get an installation to be very quiet if you spent some time making a custom enclosure in the cargo area for it as well.

Certainly to future proof the setup, buy an inverter that can take both a genset and battery bank so one or both can be hooked up into it. I think you'd get about 3KW of solar panels on the roof of the coach which would run everything easily during the day unless you parked under a tree, so you could sit there in the sun with the engine off and have the whole place as cool as a cucumber.

You'd still need some batteries to run smaller item over night, but you could start small and add as you go.

It looks the goods Gav, but I'll have to change my lunch order from bacon, egg and cheese roll to Vegemite, until I've saved eight grand.

What I've often said, it's too warm up there.

Move down here. Park under a shady tree and open a window.
It cools down most nights down this way.

None of the windows open, Mick.
