The Story
This Brookwater house now makes 97 percent of its own power. We hooked up a massive 48.4kWh battery to their existing solar. They will save over $117,934 over the life of the system. It pays for itself in under 9 years.
They just moved up from Northern NSW. Summer aircon bills in Brisbane get brutal. This huge battery means they run the house all night on stored sun. We also scored them $6,412 in government rebates.
A massive solar setup needs a massive battery. Otherwise you just send good power back to the grid for pennies. Now they dodge peak Energex tariffs completely. They make the power and they keep it.
“We had Brett & the Team do a few upgrades at our place. Installed a Sig Battery, DC EV Charger & Gateway Backup, then we had them add another 11kw of Panels some months later. We could not be more pleased with their workmanship & communication throughout both projects. The system is amazing … we’ve lost power from the grid a couple of times, the system has switched over to the backup without losing power. Our EVs now have the ability to be charged at incredible speeds & we’ve not needed to purchase power. If you have solar & battery needs, I’d highly recommend Connect Energy, the support they’ve provided is outstanding.”
We integrated 48.4kWh of battery storage into their existing 15kW solar setup. The system uses two 15kW Three Phase inverters split across two battery stacks. We also installed a 25kW vehicle to grid bidirectional DC charger. A Three Phase backup gateway handles any grid outages.

The Solution
Connect Energy added 48.4kWh of battery storage to this Brookwater home’s existing solar system.
System Performance
The battery stores surplus solar generation for evening and overnight use, covering 97% of the household’s annual energy consumption.
Financial Impact
This system significantly reduces the household’s electricity costs, with savings that grow as energy prices rise.
Government incentives applied to this project included Small-scale Technology Certificates (STCs) and the federal Cheaper Home Batteries Program, which together reduced the upfront cost by over $6,412.
