Big battery question

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

No it means that connecting the 3 phases in delta (instead of star) it will draw 12A. 

Simply put the star and delta refers to how the 3 coils / windings of the motor are connected to the supply, so in star one end of each winding is connected together, in delta you could say they are daisy chained with the end of one coil getting connected to the start of the other.

Milwaukee are releasing their new batteries soon that they claim you can run TVs and microwaves on. The tools look very good but they'll be in the thousands.

No it's 3ph and draws 12 amps when switched as delta and  7 when switched as star. I think that means you start it star and then once it's running switch to delta although both those voltages time Amps give the same ~2.7kW

 

it makes 2.7 kW with a power factor of .8 so you need to supply 1.25 as many amps at the voltage to get that power.

 

A 3ph Tesla powerwall perhaps might run it.

No problem.

 

weighs about 1200kg & holds about 52kWh of energy

 

Currently connected to 2 x 5000 paralleled inverters but if I add a third one I can set it up as 3 phase.

Thanks fir the replies.
I still don't see any technical issues other than a huge transformer?
One day a tesla wall will fit in the palm of your hand.

What are your trying to do or test ??

Is this what you need

There's an old 3ph Saw on eBay.
Thought about using fir milling.
Then thought hmmmmmm.
5kg battery and transformer.
10-30 seconds run time is proof of concept?
Just don't want it to explode....

Pm me the link and i will look at the plate rating for you

Its also duty cycles on stuff. Try arc welding heavy metal. You wont do it all day. Have a rethink mate- there is always a (safer ) work around in ( electrical ) engineering. K
