About this solar installation in Virginia

The Fronius stays. This Virginia home already had an 8 kW Fronius solar inverter, and the new Sigenergy battery system was built to work with it. The Fronius is AC coupled to the new Sigenergy inverter.

That inverter is a Sigenergy SigenStor EC 8.0 SP, single phase, rated at 8.8 kW. Four Sigenergy SigenStor BAT 8.0 modules stack on a clean garage wall, 31.2 kWh usable, with a small isolator box above them and a bollard beside them for protection.

A Sigenergy single phase gateway gives backup to the circuits that can be backed up, so selected circuits stay powered through an outage. Sigenergy is a brand we are certified to install.
