WA Solar Battery Rebate: Growing List of Eligible Systems

Will Solar Battery Prices in NSW and ACT Rise Due to Stock Shortages in 2025?

Big Savings Ahead for WA Households

The WA Solar Battery Rebate is creating a buzz across Western Australia, making solar storage more affordable than ever. The rebate program not only reduces upfront costs but also ensures households choose systems that are safe, efficient, and ready for the future. The exciting part? The list of eligible inverters and batteries continues to grow—though slowly.

At Stag Electrical, we’re here to guide you through the maze of approved systems, rebate requirements, and the best inverter-battery combos available in WA.

Understanding the WA Solar Battery Rebate

The WA Government’s Residential Battery Scheme offers rebates for homeowners who install a compliant solar battery system. The rebate ensures households benefit from reliable technology while supporting grid stability.

  • Synergy Area (Perth & SW WA): Up to $1,300 ($130 per kWh, capped at 10 kWh).

  • Horizon Power Area (Regional WA): Up to $3,800 ($380 per kWh, capped at 10 kWh).

Better still, these rebates can be stacked with the Federal “Cheaper Home Batteries” program, allowing households to save up to $5,000–$7,500 on a new system (SolarQuotes, WA Government).

Why Eligible Systems Matter

Not every solar battery setup qualifies for the rebate. To be eligible:

  • Inverter must be on WA’s Supported Solutions List (Synergy).

  • Battery must be CEC-approved (see the Clean Energy Council’s approved battery list).

  • System must be VPP-ready (Virtual Power Plant capable).

This ensures your investment is safe, future-proof, and contributes to a smarter grid.

The Growing List of Eligible Systems

The WA Government and Clean Energy Council update the list regularly. While the process has been slow, more solutions are being added as manufacturers gain approval.

Here are some of the most notable options:

Sigenergy SigenStor - H3

  • Now listed on Synergy’s Supported Solutions List.

  • Known for modular design, fire safety features, and advanced AI management.

  • One of the most popular rebate-eligible choices in WA (SolarQuotes).

Growatt ALP LV Series

  • CEC-approved, modular, and cost-effective.

  • Expected to gain full eligibility on WA’s list soon.

  • A great choice for homeowners seeking affordability without compromising performance (Solar Power Nation).

Other Contenders

  • Select hybrid inverters from Fronius, Sungrow, and Huawei.

  • Battery systems from BYD and Tesla that meet CEC standards.

The bottom line? The list of eligible inverter + battery combos is expanding, giving WA homeowners more flexibility in system design.
