About this solar installation in Mannum

At this Mannum home the switchboard work came with the solar. The main switchboard and a sub board were upgraded, outdoor and indoor, and a Hager EH010 timer was fitted to the hot water so that controlled load is no longer always on.

Then the system itself: 33 LONGi Hi-MO X10 Explorer panels of 475 W each, a GoodWe ESA GW9.999K-EHA-G20 inverter rated at 10 kW, and four GoodWe GW8.3-BAT-D-G20 battery modules, 32 kWh usable. Full house backup is included.

The panels are on the south-east face of an older corrugated roof, fixed with Klip-Lok brackets. The battery tower stands against a garage wall, with conduit running up to a DC isolator box.
