Quattro 24/5000 3 phase amperage vs single phase output?

Hi,

I'm trying to find information on the 3 phase amperage output of the Quattro 24/5000. In single phase, single unit operation it will output 4000w at 230v = 17.3amps.

In 3 phase operation 3 will push out 12,000w (12kw). Is this 12,000/230vac or 12,000/400vac?

Is the circuit protection and cable rating for the wiring from the 3 unit cluster going to be 52amp (230vac) or 30amp (400vac)?

Any help is really appreciated.

In a star- connected ( 4 wire) three phase system the phase current equals the line current.

So the same current value as if it was single phase for a 4 wire system.

(P = SQRT(3)*Vline * Iline for a three phase system).

it's 12000/230/3

circuit protection and wiring depend on a lot of things, maximum input fusing is the rated throughput current.

But -please- consult an electrician (or Victron installer) for these kind of systems.

@Boekel thank you, will be getting it all verified, just trying to put together a bill of materials for budgeting and trying to understand what cabling and protection cost to estimate.


@Phil_Gavin thank you, makes sense.
