battery storage and 3 phase power

[rxd]

g'day gurus

we have obviously AGL channelled current at home, and 5 Kw of solar on the roof

we have 3 phase power in to the house off the grid 'cos we have an oven/induction hot plate set in the kitchen, and a condenser pump in the floor heating system, that both use 3 phase

as i understand it, the rest of the house's kit just draws the single phase (tho' that is an assumption)

i am contemplating putting in a storage battery [the Sunverge large looks just the thing]

so, the question to which my primitive (matriculation 1964) physics cannot fathom an answer:  how does such a battery storage system cope with, supply current to, kit that draws 3 phase?

thanks in advance for, i hope, some enlightenment

Hi I have a Tesla powerwall 2 installed on my property which is 3 phase, Im going to try and simplify how the Tesla works with 3 Phase system with solar. There are several configurations that can be done. I have a 3 Phase solar inverter, when the grid goes off the inverter will not work as the supply from the powerwall is single phase unless you have 3 powerwalls on different phases. For the sake of the explanation, 1 powerwall and 3 phase inverter, the tesla uses CT clamps around all three phases which measures the power on all 3 phases. Let say the powerwall is connected to the red phase and you are using power on the blue phase the powerwall will put power onto the grid the same amount you are using, but the meter is a net meter which means instead of giving you a low export meter rate it effectively cancels out power used.

Nice one @rivrydree. thanks for sharing that!
