Solar Battery Costs: Are They Worth It?

Most high-quality solar batteries in Australia last between 10 to 12 years, depending on usage and brand. Premium options are backed by strong warranties, ensuring your investment is protected for years to come. The size of your solar battery depends on your household energy consumption—specifically, how much electricity you use during the day versus at night. The SolarEdge intelligent inverter solution maximises power generation while lowering the cost  of energy produced by the PV system, for improved return on investment. SolarEdge released its first energy storage solution in 2021 with the announcement of the SolarEdge Home Battery. Since its founding in 2006, SolarEdge has been at the forefront of whole-home energy technology - from solar panels to micro optimisers to solar inverters to EV chargers to batteries.
Based in Silicon Valley, FranklinWH aims to  enhance home energy resilience and efficiency through its advanced, all-in-one smart energy storage systems. Like the Powerwall 2, the Franklin system is an AC-coupled battery system, meaning it can seamlessly connect to almost any existing solar inverter or microinverter system. However, Franklin has integrated several smart load control and power management features to get an edge over adelaide solar battery the competition.

Known for their high-performance and cost-effective products, Sungrow’s batteries and inverters are designed to meet the needs of both residential and commercial customers. Founded in 2017 by the leading engineers from Huawei group, Sigenergy was relatively unknown until the launch of the innovative, all-in-one Sigenstor energy storage system in 2023. The highly scalable rack mount batteries are available in various sizes and voltage options to suit all kinds of on-grid or off-grid installations. The latest offering in the 48V range is the Life4838P battery featuring 3.8kWh of storage, a new smart BMS, a 63A dual pole circuit breaker and an improved warranty. Tesla is one of the leading solar companies globally which is known for its advanced lithium-ion battery technology, sleek designs, and tremendous performance. It’s designed to maximize solar energy usage in homes with an impressive energy storage  capacity that can power your home during the night or grid failure.
Our online quote comparison tool compares some of the leading options in your area and you can transparently browse through their quote and company information on our portal. Enphase’s IQ 5P battery comes in 5 kWh units that can be added to at any point in time. The Enphase solar battery also boasts one of the longest warranties in the industry. While they are a high-performing battery, they don’t represent the same sort of value as other popular batteries.
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.

Operating independently of the solar inverter, the Powerwall 2 is an excellent fit for both new installations and upgrades to existing solar setups. One of its key features contributing to an enhanced user experience is the user-friendly energy monitoring app. This list offers a straightforward comparison of leading batteries, focusing on performance, reliability, and value for Australian consumers. Whether you’re a homeowner looking to reduce your carbon footprint or a business seeking energy independence, this guide is for you.
If you already have Enphase microinverters—or just want bulletproof reliability—the Enphase IQ Battery 5P is hard to beat. Each 5 kWh pack has its own microinverter, eliminating a single point of failure and letting you start small. The 15-year / 6,000-cycle warranty is among the longest on the market, and performance data from thousands of Aussie rooftops shows degradation under 2 %  per year. The Tesla Powerwall 3 (13.5 kWh usable) folds a 20 kW, three-MPPT solar inverter into its slim casing, making it an elegant single-brand package for new builds.
Rhea’s excellent customer service skills greatly contributed to my positive experience with Arise Solar. It’s clear that they prioritize customer satisfaction and employ individuals who are dedicated to upholding these values. I highly recommend Arise Solar for anyone in need of their services, and I am confident that their team, especially representatives like Rhea, will go above and beyond to meet your expectations.

At his rate, using an electric heater could completely drain a full 10 kWh battery in around 3 hours. If you are looking for a brand that really stands apart in the current Australian solar market, Alpha ESS really does it. Founded in 2012, this company is known  to manufacture some of the most efficient batteries out there.
Alternatively, you can leave space on the side for wall-mounted expansion. Not all batteries are capable of providing power to your home during a power outage. For brand-level cost breakdowns, visit our Solar Battery Price Index for a more detailed look. All these Solar blankets with MPPT controllers come with Anderson plugs. I don't know how else to connect to the battery except through the Anderson Plug. I am concerned that if I connect it there without the controller I might cause battery damage.

Keep in mind, a more complicated installation will bump up costs considerably, given architectural and technical factors can increase the time, work and components a job requires. Most households are likely to benefit from a battery with a decent amount of capacity, about 10kWh or more. But a smaller battery can be sufficient for small households with low energy usage. With the launch of the federal government's $2.3 billion Cheaper Home Batteries Program in July 2025, interest has gotten even hotter. Commonly known as the solar or home battery rebate, this new incentive offers around 30% off the total cost of installing a battery in eligible homes and small businesses.
Enphase IQ Battery 5P takes the top spot based on warranty, tech features, fire safety, and flexibility. There are new names popping on the battery market and many have fallen away too. Tesla throughput warranty higher if only used for basic functions like self-consumption.
