25.5 kWh home battery with hybrid inverter, three-phase

A three-phase connection calls for a SolaX X3 Hybrid 5.0-G4 inverter with five Triple Power modules of 5.1 kWh, 25.5 kWh of storage together.

This combination suits a household with both a heat pump and an electric car charging at home through a three-phase charger, usually paired with a roof with enough panels to run both largely on its own power through the season. For a family without those two heavy users this quickly becomes more battery than needed.

SolaX itself describes this setup as one of the possible configurations for the X3 Hybrid G4, well within the limits the inverter can handle according to the manufacturer.

The price is the sum of inverter and five modules, rounded down, with certified installation to the Dutch NEN 1010 standard included. You pay no more than ordering separately.
