Battery in Riverhills: Case Study Snapshot

This battery in Riverhills installation shows what genuine energy independence looks like for a Brisbane household.

The Story

This Riverhills household wanted more than panels — genuine energy independence, with enough storage to power through the evening.

Connect Energy designed a 15.2kW system with 27.1kWh of battery storage, matched to the home’s energy profile.

“Absolutely outstanding from start to finish! I couldn’t be happier with Connect Energy and the installation of my Sigenergy system. From the initial discussions through to the installation, commissioning and getting everything up and running, the whole experience has been exceptional. Brett and the team were fantastic to deal with — they clearly know their stuff when it comes to Sigenergy and took the time to understand what I actually wanted to achieve, rather than simply trying to sell me the biggest or most expensive setup. My system consists of a 10kW Sigenergy inverter, 27kWh of battery storage and 15kW of LONGi Ultra Black panels, and the finished installation is absolutely fantastic. The workmanship, attention to detail and cleanliness were outstanding. There was no pressure, no nonsense and no cutting corners — just honest advice, excellent communication, quality equipment and exceptional workmanship. I would have no hesitation recommending Brett and the Connect Energy team to anyone considering solar, batteries or a Sigenergy system.”
