Big battery question

[Rough Hewn]

I'm not great with electrickery,

But I was wondering how to get 3phase power from lithium batteries?

Is it possible?

Transformers?

Serious question.

3phase used to drive big motors, think yr battery cost will outweigh project. A 1000w motor is a chuffing big pull of juice. K

Needs to be 3kw.
Even if I get 30 seconds run time.

Going 240v to 3 phase is a massive pull, your battery bank would be shot in seconds, non starter, roughy.

Oooo dunno, 3000w at 12 volts = @240amp per hour so yr inverter from DC to AC gotta be that big. Depends on wot batteries voltage you use, must be a way around it but its cost an benefit mate, k

Try find a big automotive jump pack n big inverter but get CO2 fire extinguisher whilst at it ?  K

Sounds about right, my box has got 2 110ah batteries, without killing them it's recommend that they aren't drained below 50% of their capacity. A hairdryer or microwave would kill them in a matter of minutes. No chance of getting 3 phase out of them.

Does this mean it runs on single phase at 12 amps?
