Overview

For this Mt Tamborine homeowner, the goal wasn't just to lower a bill — it was to eliminate the anxiety of unreliable grid power during Queensland's storm seasons. We installed a robust 13.3kW solar array paired with a 10kW Sigenergy inverter and modular battery stack, creating a custom energy ecosystem that turns the home into its own power station.

The Sigenergy system sits just 150mm off the wall and features AI-enabled monitoring via the mySigen app. The integrated Off-Grid Gateway automatically "islands" the home during grid failures — the transition is so seamless the family might not notice the street has gone dark. The oversized array ensures enough generation even on overcast mountain days to fully charge the batteries before sundown.

Execution

To deliver complete energy independence for this mountain property, LMS Electrical implemented the following steps:

• Custom Energy Assessment – Evaluated the property's energy needs and solar potential for mountain conditions.
• 13.3kW Solar Array Installation – Installed high-efficiency panels sized for overcast mountain days.
• Sigenergy Battery Integration – Paired with a 10kW inverter and modular stackable battery system.
• Off-Grid Gateway Setup – Configured automatic home islanding during grid failures.
• Smart Monitoring System – Set up AI-enabled mySigen app for real-time energy tracking.

Result

• Complete energy independence during grid outages and storm seasons.
• Seamless automatic transition to battery power during blackouts.
• AI-enabled monitoring via mySigen app for optimised energy management.
• Oversized array ensures full battery charge even on overcast mountain days.
• Compact wall-mounted design sits just 150mm from the wall.
