About this battery installation in Prospect

Prospect already had solar, from both Fronius and Enphase systems. The job was to add a large battery and tie the setup together.

A Sigenergy SigenStor EC 15.0 TP inverter, 15 kW and three phase, went in with six SigenStor BAT 8.0 batteries, 48.36 kWh in total. We restrung the existing Fronius system to the Sigenergy controller for DC coupling, hardwired ethernet to the Sigenergy and Enphase controllers and supplied a network switch.

A three phase gateway gives whole home backup. The underfloor heating came off the controlled load.

The tall battery stands against red brick under the veranda, with a smaller wall-mounted unit beside it. We are a Sigenergy certified installer.
