About this solar installation in Prospect

Battery and backup first, panels later. That was the plan for this Prospect home, and the customer elected zero export with the network for now. We explained that changing this later would involve a network application when panels are added.

Five Sigenergy SigenStor BAT 8.0 modules make up 40.3 kWh, paired with a Sigenergy SigenStor EC 20.0 TP three phase inverter. The inverter is 20 kW, sized to back up as much of the house as possible, and a three phase Sigenergy gateway provides the house backup.

The battery is wall mounted on a side wall along a passage, with a new isolator board and a tidy switchboard on the same wall. We are a Sigenergy certified installer.
