Best Solar Batteries to Buy With the New Federal Battery Rebate
The Australian Government is taking action to make home batteries more accessible. They initiated the new federal rebate under the Cheaper Home Batteries Program to cover up to 30% of the home battery cost. This program is a significant push to help more households afford clean, reliable energy.
If you’ve been waiting for the right time to install a battery, this rebate could be the turning point. However, not every battery on the market qualifies, and not all are created equal. This blog will discuss the best solar battery options under the new rebate, what makes them stand out, and how to choose the right one for your home.
Key Takeaways:
Rebates Make Home Storage More Affordable
Australia’s new federal rebate covers up to 30% of the cost of a home battery system, making clean energy storage more accessible than ever.
The Best Battery for You Depends on Your Needs
Your ideal battery depends on your energy goals, home size, and solar setup. From modular to all-in-one designs, different systems offer unique benefits like VPP readiness or full backup power.
Top Battery Brands Offer More Than Just Storage
Leading models like 1KOMMA5°, Tesla Powerwall 3, Sungrow, and SolarEdge offer smart energy features, app integration, and future-proof designs. These extras help maximise energy savings and enhance grid resilience.
Acting Early Locks in the Highest Rebate
Battery incentives are often capped or phased down over time. Installing early gives you the best chance to secure the full rebate amount and avoid potential delays from high demand.
What Batteries are Eligible for the New Federal Battery Rebate
To access the rebate, there are a few key criteria your battery system must meet. We have covered the federal battery rebate in a previous blog:
Cheaper Home Batteries Program Guide
But here’s a quick refresher on what your battery setup must include to qualify for the program:
CEC-approved battery
Must be listed on the Clean Energy Council’s (CEC) approved battery list.
Installed by an accredited installer
Your installer must be an approved solar professional with the right certifications.
Paired with a rooftop solar system
The battery must be connected to a new or existing rooftop solar system.
Battery capacity requirements
Eligible battery systems must have a nominal capacity between 5 kilowatt-hours (kWh) and 100 kWh. The rebate applies to the first 50 kWh of usable capacity.
Meets minimum safety, warranty, and performance standards
The battery system must comply with relevant Australian standards and have at least the set minimum warranty.
One rebate per household
You can only claim this rebate once, so choosing the right product is essential.
VPP ready (but not required to join one)
If you have an on-grid system, your battery must be VPP-ready. This feature enables participation in energy sharing networks and enhances grid stability.
Best Batteries to Install with the Federal Battery Rebate
Only CEC-approved batteries are eligible for the rebate, and for good reason. These batteries meet rigorous safety and performance standards set for the Australian market. We've made it easy for you by including only CEC-approved models in our list, provided they will be installed in a solar panel system.
Tesla Powerwall 3
All-in-One Simplicity for Energy Independence
Unlike other battery setups, Powerwall 3 does not need separate inverters and extra wiring and rolls everything into one sleek, compact unit. But it’s more than just convenience. The all-in-one design helps you save more and worry less.
Tesla’s ecosystem manages the hard stuff so you don’t have to. It automatically stores excess solar, powers your home when energy prices surge, and keeps the lights on during blackouts. The app shows you what’s happening in real time, and software updates continue to unlock new features long after installation.
Scalable Energy Storage
Allows a total storage capacity of 40.5 kWh, which is expandable with up to three additional units to meet growing energy needs.
High Continuous Power Output
Tesla Powerwall can deliver up to 11.5 kW of continuous power and back up your home, including high-demand appliances, during an outage.
Advanced Solar Optimisation
With six integrated Maximum Power Point Trackers (MPPTs), Powerwall 3 can handle solar panels facing multiple roof directions or partial shading, improving overall system efficiency.
Local Presence and Global Innovation
Tesla is a global brand, it’s well-supported in Australia through a large network of accredited installers and service providers.
Sungrow SBR Series
A Popular and Affordable All-Rounder
Sungrow has built its reputation on engineering solar systems that are reliable, affordable, and without unnecessary complexity. The SBR Series battery is no exception. It’s a solid choice for Australian households that want dependable energy storage without overspending.
Scalable, Compact, and Neat
Each battery module stacks vertically, taking up less floor space. Systems start at 9.6 kWh and can scale up to 25.6 kWh, making it easy to grow as your energy needs change.
Engineered Simplicity
The SBR Series avoids the overcomplicated tech found in some high-end batteries. Instead, it delivers streamlined performance, low maintenance, and high reliability
Safe and Stable LFP Battery Chemistry
Made with lithium iron phosphate (LFP), the battery is thermally stable, non-toxic, and safer in extreme temperatures.
Backed by Global Engineering
Sungrow is one of the world’s largest inverter and battery brands, with 25+ years in the clean energy industry. Their systems are installed in over 150 countries and are popular across Australia.

How to Maximise Your Battery Rebate
Start with an accredited solar installer.
Aside from being CEC-approved, your battery must also be installed by an accredited installer to qualify for the rebate. This isn’t just a paperwork requirement. It ensures your system is safe, compliant, and eligible for warranty support. Working with an accredited installer also gives you access to trusted advice on which batteries qualify, how to size your system, and how to avoid delays in the approval process.
Since you’re already here, why not start with us? 1KOMMA5° is a fully accredited solar installer and has helped thousands of homeowners across Australia on their solar journey. We’ll help you make sure that your battery setup is eligible, optimised, and built to last.
Check if your battery qualifies for both federal and state rebates.
Some states offer additional battery incentives on top of the new federal rebate. In some cases, you can claim both. However, stacking these rebates can involve complex rules and administrative steps. If not handled properly, it could lead to delays or complications. It is advisable to consult your solar installer about how different rebates interact. Your installer will help you navigate the process, ensure compliance, and maximise your savings.
Don’t just go for the cheapest system, but look for long-term value.
Some batteries may seem budget-friendly upfront, but lack features that will help you save in the long run. Look for systems that are:
VPP- ready – Can the battery connect to a Virtual Power Plant and earn extra income?
Has smart energy apps – Does it come with a mobile app to track usage and savings?
Has long warranties – Are you covered for at least 10 years of performance?
If you can install now, don't wait too long.
Battery rebates aren’t guaranteed to stay at the same value forever. STCs are already set to phase down each year until 2030, and your total savings could shrink the longer you wait.
Additionally, government rebates are often released in stages or capped by the number of applications. The longer you wait, the greater the chance you’ll miss the rebate entirely or end up with a lower subsidy amount. By acting early, you can lock in the highest available rebate and beat the rush.
