Sigenergy and Sungrow are two of the more popular Chinese-made battery brands in Perth right now, and they're often shortlisted against each other. Both are modular, but they take different approaches: Sigenergy's SigenStor is a high-power DC tower with strong backup options, while Sungrow's SBR/SBH range pairs with its own widely-installed hybrid inverters at competitive value. Here's a fair, spec-led comparison for WA homes. Sigenergy's SigenStor line spans two CEC-approved hardware generations — modules first approved Jan 2024 and a newer generation from Jan 2026 — both remain CEC-active and individually resolvable; see the generation breakdown for what changed.
Quick answer
The choice mostly comes down to whether you prioritise Sigenergy's higher power and backup capability or Sungrow's lower cost per kWh and longer market track record. Pick Sigenergy if you want high power output and strong three-phase or whole-home backup from an all-in-one stack. Pick Sungrow if you want a lower cost per kWh and a longer, well-established track record. For either brand, WA Battery Scheme eligibility comes from the system's Synergy SSL listing, with up to $1,300 off an eligible battery.
