The Story
This Wishart household is on track to save more than $89,510 in power bills. We originally installed a solar system here in 2017. The owners recently wanted to add a battery to utilise government rebates. We claimed $4,162 upfront for them.
The subtropical sun now fills a massive 18.1kWh battery every day. They generate 9,244 kWh annually. This covers their summer aircon completely. They pull zero grid power overnight.
The payback period on this upgrade is under 3 years. Energex tariffs keep climbing but this home is covered. They keep the savings in their pocket.
“The new battery is awesome and the monitoring app is great. The solar charges it to full every single day. I am not using any grid power overnight at all.”
We originally installed a SolarEdge system for this client in 2017. They reached out to add battery storage and use the available government rebates. The Sigenergy system is highly versatile. We simply AC coupled their existing SolarEdge inverter directly to the new Sigenergy Gateway.

The Solution
Connect Energy installed a complete solar and battery solution for this Wishart home, selecting premium equipment suited to the site’s generation profile.
System Performance
The system generates 9,244 kWh per year, with the battery storing excess daytime generation for evening and overnight use.
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 Queensland Cheaper Home Batteries Program, which together reduced the upfront cost by over $4,162.
