What are the Best Solar Batteries to Choose?

They have a high energy density and can be recharged quickly, but they are also the most expensive type of battery. Enphase Energy is the leading supplier of microinverter-based solar and battery systems that enable people to make, use, and save. There are a number of rebates and incentives available for solar batteries, depending on where you live. Be sure to research these rebates and incentives before you purchase to maximise your savings.
It is capable of charging multiple devices simultaneously, making it ideal for a variety of situations. With flexible recharging options, including solar panels, AC power, or a car charger, the EP500Pro ensures you have a continuous and sustainable power supply at all times. Its smart touchscreen and app remote control feature make it convenient government grant for battery storage and easy to use, putting control at your fingertips.

Affordability does not mean a compromise on quality with the B2 series. The Tesla Powerwall 2 14kWh, priced between $12,000 and $14,000 in Australia, stands out as our top choice for AC-coupled batteries. Now that we’ve seen the overview of our top 9 picks, let’s dive deeper into each brand and model.
Renowned for its high quality, this battery excels in offering compatibility with various inverter options. Some battery systems require a separate hybrid or battery inverter, adding to the cost. When it comes time to reset the system, a panel must be removed to access the switchboard. This means the system looks great, but it can be daunting for some battery owners. At Plico, we assist our members manage their system for optimal performance.
The Tesla Powerwall is one of the most trusted and reliable solar batteries currently on the market, offering an energy capacity of 13.5 kWh per unit. With the ability to scale up to 3 battery units per inverter (with the help of a branch connector), you can store up to 30kWh of energy with SolarEdge in Queensland. SigenStor is AI-optimised, and the mySigen App is proven to provide intelligent optimisation suggestions on your system’s mode, battery capacity, and energy usage. MySigen App, like the Tesla App, also offers an excellent UI that’s easy to use and understand.

That includes matching system size to daily use, choosing components that work well together, and ensuring your investor and battery setup can handle future upgrades. A rushed installation might beat the rebate deadline, but a well-planned one  beats the market. As incentives taper off, system performance, durability, and customer support will define long-term savings far more than short-term discounts ever could. Choosing a reputable solar battery brand is crucial for long-term performance, safety, and support. In 2025, Australian homeowners have access to a growing range of high-quality batteries, each with different chemistries, warranties, and pricing.
This guide introduces the best solar batteries in Australia for 2024, helping you make an informed decision for your energy needs. The Australian government and some state governments offer various incentives, rebates, and subsidies to encourage the adoption of solar energy and storage systems. These can significantly reduce the upfront cost of purchasing and installing a 10kW solar battery. The Smile-B3 Plus comes jam-packed with advantages like expansion, compatibility, and easy installation. The Smile-B3 Plus works with all solar inverters and comes Virtual Power Plant ready, meaning its performance and safety make it suitable to participate in VPPs. Ideal ForThe GoodWe Solar Battery is ideal for homeowners seeking an efficient, reliable, and cost-effective energy storage solution.
A few factors can affect the DoD that  can be used in Australia, such as the type of battery, the climate, and how the battery is used. For example, lead-acid batteries are typically discharged to a lower DoD than lithium-ion batteries. Batteries used in hot climates will also need to be discharged to a lower DoD than those used in cold climates. And batteries used for short bursts of power, such as starting a car, can typically be discharged to a lower DoD than batteries used for a steady stream of power, such as powering a solar panel system.

A solar system that is capable of exporting excess energy back to the grid requires SAPN approval, while a new bi-directional electricity meter will need to be installed (or your existing one re-programmed).

They are made up of lead plates immersed in a mixture of sulfuric acid and water, commonly known as an electrolyte. This battery stores electrical energy through chemical reactions involving lead, water, and sulfuric acid. With modular designs, high efficiency, and robust safety standards, Solax batteries offer dependable performance tailored to Australian homes and long-term energy needs.
Solar batteries generally cost around $1,000 to $2,000 per kilowatt hour (kWh) of storage capacity in Australia. For example, for a 4kWh battery, you’ll spend between $4,000 to $8,000. If you have a high daily electricity consumption or want to store more energy for backup purposes, you may need a larger battery.

Typically, solar batteries will cost between $4,960 to $12,400, depending on the battery size. However, the  price can differ based on brand and can increase with a larger battery size. The cycle life of a solar battery refers to how many times it can go through a full charge and discharge cycle and get to a specific discharge level.
Larger systems (10+ kWh) offer better value, with costs as low as $440/kWh for 25.6 kWh batteries. Learn more about battery-ready solar systems and how solar battery installation work. Safety is a common concern for homeowners considering a battery storage system. Whether you’re retrofitting a battery to an existing solar setup or installing a completely new solar and battery system, this guide has everything you need to make an informed choice. I will have to have another look at where the solar panels connect in but probably can’t access. Unfortunately the batteries are in a dreadful place under the seat in the van, after removing an awkward cushion.
