Inverters

#4 of 9 inverter brands
Excellent, modern hardware that installers rate highly. It's a young company and had a recall in 2025, handled with replacements, so the track record is still building.

#1 of 9 home battery brands
Our top-rated battery brand. SigenStor is the installers' favourite and Australia's most-installed home battery, with top specs and an easy path to expand. The 2025 controller recall was handled with replacements, but it's a young company.
