Which Battery Should You Buy with the Federal Battery Rebate 2025? – Complete Guide
If you're planning to take advantage of the 2025 Federal Solar Battery Rebate, you're already making a smart move toward lowering your power bills and increasing your energy independence. But the next big question is: Which solar battery should you buy?
With so many options on the market — and your eligibility for thousands in government rebates — it’s important to choose a system that fits your energy needs, budget, and long-term goals.
This complete guide will walk you through the best types of solar batteries available in Australia in 2025, what to consider before buying, and how to get the most value from the solar battery rebate.
Federal Battery Rebate 2025: What It Is
The Federal Battery Rebate is a government-backed financial incentive introduced to make home battery storage more affordable for Australian homeowners. It reduces the upfront cost of installing a solar battery, allowing more people to store excess solar power for use at night or during blackouts.
Depending on your system size and eligibility, you could receive between $1,000 to $18000 off your installation. This rebate may also be combined with state-based incentives in some areas.
Why Your Battery Choice Matters
Not all solar batteries are created equal. While the rebate makes things more affordable, it’s still a major investment — so choosing the right battery will affect your:
1. Energy savings
2. System lifespan
3. Backup capacity
4. Return on investment (ROI)
The best battery for your home will depend on your energy usage, system setup, and goals (e.g., bill reduction, blackout protection, grid independence, etc.).
Key Factors to Consider When Choosing a Solar Battery
Before you look at specific brands, it’s important to understand the main things that affect a battery’s performance:
1. Battery Capacity (kWh)
Measured in kilowatt-hours (kWh), capacity tells you how much energy the battery can store. Most homes benefit from a battery size between 10kWh to 30kWh, depending on energy use.
2. Usable vs. Total Capacity
Not all the battery's capacity is usable. Some batteries have a depth-of-discharge (DoD) limit — meaning only part of the stored energy is available. Look for batteries with 90–100% usable capacity.
3. Warranty and Lifespan
A good battery should last 10 years or more, with at least 70–80% capacity retained for 10 years. Choose models with comprehensive warranties covering performance and defects.
4. Hybrid Compatibility
If you don’t already have solar panels, consider buying a hybrid inverter and battery combo. This ensures everything works together seamlessly and can increase rebate eligibility.
5. Virtual Power Plant (VPP) Ready
Some battery rebate programs prefer or require systems that can join a Virtual Power Plant. This means your battery can support the local grid — and you may earn credits in return.

Should You Go With a Hybrid System?
If you’re just starting out with solar, a solar + battery bundle might give you a better deal and access to more rebates. Hybrid systems are typically more efficient, easier to monitor, and may be required for some federal and state rebates.
Can You Claim the Rebate for Any Battery?
No. To be eligible for the Federal Battery Rebate, your battery must:
1. Be on the Clean Energy Council (CEC) approved battery list
2. Be installed by an SAA accredited installer
3. Meet certain safety and performance standards
Ask your installer for a list of rebate-eligible products before making your purchase.
