About this battery installation in Hillbank

Take off the Fronius inverter and put a Sigenergy battery in the garage. That was the brief at this Hillbank home.

The new inverter is a Sigenergy SigenStor EC 20.0 TP, 20 kW and three phase, with five SigenStor BAT 8.0 modules. Each is 8.06 kWh, or 7.8 kWh usable, so 40.3 kWh in total and 39 kWh usable. The old Fronius AC cable is reused for the inverter supply. A three phase Sigenergy gateway sits next to the switchboard and provides house backup.

The tall white battery stands against a brick wall, with the one bollard installed beside it, white and red. A Fronius inverter with a labelled isolator box appears in the photos, wall-mounted on red brick under the carport.

We are a Sigenergy certified installer.
