Is SigEnergy a good battery?
Owners like the modular stack and the app. It's a newer brand than Tesla, so ask any installer how many they've fitted and how they handle warranty claims. We're happy to answer both on the call.
SigEnergy vs Tesla Powerwall 3 vs Sungrow
SigEnergy suits people who want to grow capacity in steps. Powerwall 3 is the simplest single box with strong backup. Sungrow is often the value pick. See the comparison on our batteries page.

“My power bills are virtually non existent now”
Amazing service!!! Michael and his team showed up on time and delivered everything they promised. They cleaned up after themselves and all the team were so polite. Getting solar and batteries was a bit of a struggle to navigate, however once i spoke with michael I had peace of mind. We did have an issue with the app connecting which micheal sorted out straight away. Highly recommended. Thanks you so much. My power bills are virtually non existent now🙌

From the initial consultation to the final walkthrough, the entire process was seamless, transparent, and completely stress-free. The highlight of the experience was definitely the installation team. They were professional, efficient, and incredibly respectful of our property from start to finish, completing a flawless job ahead of schedule. Highly recommended! Thank you Micheal and team!
