36.16 kWh home battery with hybrid inverter, 3-phase

With four SigenStor Battery 10.0 modules you hit the maximum of the three-phase Sigen Energy Controller 8.0 kW: 36.16 kWh usable capacity, a scale at which you're really building an energy home rather than adding a battery. That inverter spreads 8 kW of power across three phases, even when the heat pump and the car are both asking for power at the same time.

This package is for a large house with a heat pump, a car that charges at home and annual consumption well above average, on a home with a three-phase connection. With four modules you get through a number of dark days without having to buy in much from the grid, depending on how many solar panels you have. For an average household without a heat pump this is generously oversized; take a look at one of the smaller packages above instead.

For this combination too, Sigenergy tests it themselves with the SigenStor BAT 10.0 on a three-phase Energy Controller, as stated in the datasheet of the Sigen Battery. Four modules on this inverter isn't an arrangement of our own making, but a setup within what the manufacturer itself describes.

For the largest package in this range the same rule applies as for the smallest: inverter plus all the modules added up separately, rounded down. With four modules that saves you most of the calculating yourself, without costing you more than ordering separately.
