What 3P inverter

Hi,

I own 24 (310wp) solar panels split over 3 phases on Enphase. So... no DC. Grid tied 230V AC only.

Now i would like to attach a 10-15 kw LiFoPo4 Home battery.

Could i use one inverter to combine the 3 phases to charge one battery? Or do i have to buy 3 inverters (one for each phase) and 3 batterys?

I would like to run my home appliances by solar power.

The "house" has 2 heavy loads. One 3P (6kw max) heatpump and an EV charger. (22kw reduced to 8kw so i can mostly charge within the solar curve.)

Could someone please tell me what inverter would be suitable?

I just would like to figure out the costs.

If i need to triple everything....

:'-(

Very expensive!


Ben

best solution is to look at a 3 phase set of inverters - this would be easiest to integrate, the good news is that they can share a common battery - though this does have to be sized appropriately. with 7kW solar, and various loads you could make the system as small as 3 x 3kW, or better 3 x 5kW.
