9.9 kW solar + Sigenergy battery install in Craigieburn — day on the tools

This is a sample "daily work" post showing the format — replace with your first real job write-up and video.

Today's job: a 9.9 kWp system with a Sigenergy battery and essential-circuit backup on a single-storey home in Craigieburn.

What we did

  • 22 × 450 W panels across the north and west faces — west array catches the evening peak
  • Sigenergy SigenStor battery with backup module
  • Essential circuits (fridge, lights, internet, garage) wired to the backup supply
  • Switchboard tidy-up and labelling while we were in there

What we learned

The west-facing array decision is worth a note: the customer works from home and uses most power from 3–7pm, so we traded a little total generation for a lot more self-consumption. Design from the bills, not the compass.

The numbers at commissioning

System switched on at 2:40pm, immediately generating 6.1 kW under light cloud. Monitoring set up on the owner's phone before we left.
