February 2026 Smashes Battery Records: 1.2 GWh Installed in a Single Month
Record-Breaking Month
February 2026 saw 1.2 GWh of small-scale battery storage registered — the highest single month on record. The surge is being driven by homeowners racing to complete installations before the 1 May 2026 rebate reduction. Rooftop solar also rebounded to its largest February total ever.
A Record Month Driven by Urgency
Data from solar industry analyst SunWiz confirms that February 2026 was the biggest month ever for home battery registrations in Australia. A total of 1.2 GWh of small-scale energy storage capacity was registered — a 24% increase from January 2026.
SunWiz Managing Director Warwick Johnston explained the surge: “The pressure to complete installations before rebate changes on 1 May pushed registrations to a record month.”
Johnston also noted that “this continues the volatile start to 2026 after a strong finish to 2025, with demand remaining robust despite signs of market maturity.”
February 2026 at a Glance
Rooftop Solar Rebounds Alongside Batteries
It wasn't just batteries setting records. February 2026 also saw 281 MW of new rooftop solar capacity registered — up 57 MW from January and the largest February total on record. Year-to-date solar installations are running 6% ahead of 2025 volumes.
The data shows Australians are increasingly opting for combined solar-plus-battery systems. The average battery system size was 10.34 kW, with the 40-50 kWh segment dominating installations as households invest in larger storage capacity to maximise self-consumption and grid independence.
Every State Saw Growth — Some Exceptional
The February record was a nationwide phenomenon. All states and territories recorded increased battery registrations, with some regions seeing dramatic growth.
State Highlights: February 2026
Why the May 1 Deadline Is Driving the Rush
The record demand is directly linked to the Cheaper Home Batteries Program undergoing significant changes on 1 May 2026. The federal STC factor drops from 8.4 to 6.8, immediately reducing the rebate value for new installations. Rebates will then decline every six months instead of annually — accelerating the cost increase for homeowners who delay.
For a typical 13.5 kWh battery system, the difference between installing before and after the May 1 deadline can be $2,000 to $3,000 in lost rebate value. This financial reality is pushing homeowners to finalise installations now rather than waiting.
Larger Systems Are Becoming the Norm
An emerging trend in the February data is the growing popularity of larger battery systems. The 40-50 kWh segment dominated installations, reflecting a shift toward whole-home energy independence rather than partial backup. While the average system size dipped slightly to 10.3 kW (from 10.34 kW in January), the industry is moving toward battery-centric installations where the battery is the primary investment, with solar designed to support it.
