About this solar installation in Mount Barker

This Mount Barker home already had panels on the roof. We kept them, took the old inverter off the wall and restrung the existing array into a new GoodWe ESA inverter rated at 10 kW.

Then the roof got more. Fourteen LONGi Hi-MO X10 Explorer panels at 475 W each, 6.65 kW in total, now sit on the same dark corrugated iron. Inside, on the left as you walk into the garage, three GoodWe GW8.3 battery modules stack up with 8 kWh usable in each.

The switchboard was upgraded so the whole house stays on in a blackout, not just a few circuits. A GoodWe EV charger went in as well, placed where the owners wanted it.
