About this battery installation in Waterfall Gully

The Sigenergy battery at this Waterfall Gully home was installed where its Tesla Powerwall 2 had been.

The inverter is a Sigenergy SigenStor EC 15.0 TP, 15 kW and three phase, with six SigenStor BAT 8.0 modules. Each is 8.06 kWh, or 7.8 kWh usable, so 48.36 kWh in total and 46.8 kWh usable. The three phase Sigenergy gateway for house backup went into the wall behind the battery, as it did for the Powerwall 2. The system is AC coupled to the existing Enphase solar, and the switchboard was upgraded.

The tall white battery stands on the floor against a dark brown wall in a covered entry, with a white bollard in front of it. A neat grey conduit run goes into a junction box beside it. We are a Sigenergy certified installer.
