Ultimately, choosing the right battery depends on factors such as energy requirements, budget, available space, and individual needs. Consult with solar and energy storage experts and stay informed about market trends and new technologies for best results.
Best Solar Batteries in Australia
For Australian homeowners with solar panels—or those planning to install them—one big question comes to mind: Should I add a solar battery? Solar batteries let you store excess energy generated during the day, offering greater energy efficiency, lower electricity bills, and peace of mind during blackouts.
Australia has a wide range of solar batteries available. But which one is right for you? That depends on your specific needs, from capacity to budget. Here’s everything you need to know to make an informed choice.
How to Choose the Best Solar Battery for Your Home
Selecting the right solar battery requires understanding key performance factors. Here’s what to consider:
Battery Capacity
- Measured in kilowatt-hours (kWh), capacity determines how much energy your battery can store.
- Plan for the future: If you’re adding an EV charger, you’ll need more storage.
Power Rating
- Power rating (kW) indicates how much energy a battery can deliver at once.
- Higher power ratings allow you to run more devices simultaneously.
Depth of Discharge (DoD)
- DoD represents how much of a battery’s capacity can be used before recharging.
- Higher DoD = More usable power per charge.
Backup Power Capabilities
- Not all solar batteries provide blackout protection.
- Choose a battery with built-in backup features if energy security is a priority.
Warranty & Lifespan
- A battery’s warranty indicates its expected longevity.
- Look for a 10-year warranty from a trusted brand.
Top Solar Batteries in Australia
Tesla Powerwall 2 & 3
The Tesla Powerwall 2 & the Tesla Powerwall 3 are one of the most popular and advanced solar batteries in Australia, offering high storage capacity, smart energy management, and seamless backup power.
Designed as a fully integrated AC battery, it comes with a built-in inverter, allowing for easy integration with new or existing solar systems. Its 5 kW continuous power output ensures it can handle multiple appliances at once, while the 7 kW peak power output provides extra energy when needed (e.g., starting large appliances).
With Tesla’s world-class monitoring app, you can track energy production, consumption, and storage in real-time. The Powerwall automatically detects blackouts, ensuring your home remains powered when the grid goes down.
SonnenBatterie Evo – Built for Safety & Longevity
The SonnenBatterie Evo is a German-engineered solar battery designed with longevity, safety, and reliability in mind. Using Lithium Iron Phosphate (LFP) chemistry, it is non-flammable, thermally stable, and capable of 10,000+ charge cycles—one of the highest in the market.
Its modular design allows for a customisable storage capacity, and it offers both AC and DC coupling, making it compatible with a wide range of inverters.
The SonnenBatterie is one of the few batteries built with rugged Australian conditions in mind, featuring IP56 weatherproofing, allowing outdoor installation without additional housing.

Sungrow SBR HV – Best Value for Money
The Sungrow SBR HV is a high-quality, cost-effective solar battery that offers great performance at a lower price than Tesla. It features a modular design, meaning you can start with a smaller capacity and expand up to 12.8 kWh by stacking multiple 3.2 kWh battery units.
Unlike some budget batteries, Sungrow uses Lithium Iron Phosphate (LFP) technology, known for safety, longer lifespan, and thermal stability.
It integrates seamlessly with Sungrow hybrid inverters, making it a great option for new solar installations. However, if you already have an existing solar system with a different inverter, you’ll need to check compatibility.

Enphase IQ Battery – Best for Smart Monitoring & Enphase Users
The Enphase IQ Battery is perfect for homeowners already using Enphase microinverters. It provides seamless integration, meaning you can monitor your entire solar system and battery storage through the Enphase App.
While it has a smaller individual capacity (3.5 kWh) than other batteries, it can be stacked to 10.5 kWh for more storage.
It also uses Lithium Iron Phosphate (LFP) chemistry, making it safer and longer-lasting than older battery types.
BYD Battery Box Premium – Best for Scalability & Large Homes
The BYD Battery Box Premium is a highly modular solar battery that provides unmatched scalability, making it ideal for both small homes and large-scale solar storage needs.
Unlike fixed-capacity batteries, BYD’s modular design allows users to start with a 4 kWh unit and expand up to 256 kWh—making it one of the largest expandable home battery systems available.
Its LFP chemistry ensures safety and longevity, and it’s compatible with a range of inverters, including Fronius, Sungrow, and GoodWe.

Sigenergy – The Future
Sigenergy’s SigenStor is an innovative 5-in-1 home energy storage system that integrates a solar inverter, power conversion system (PCS), energy management system (EMS), EV DC charging module, and battery pack into a single, streamlined unit. This comprehensive design simplifies installation and enhances energy efficiency for homeowners.
The SigenStor’s combination of modular design, advanced safety features, AI optimisation, and EV integration makes it a compelling choice for homeowners seeking a comprehensive and future-proof energy storage solution.
