Solar batteries store excess electricity generated by your solar panels, allowing you to use more of your own solar energy when your panels are not producing power. Instead of sending all your unused daytime energy back to the grid, a battery system stores it for use later in the day.
A home battery storage system can help you make better use of the solar energy your home already generates. Stored energy can be used in the evening, overnight or when production is low, helping reduce your reliance on electricity from the grid.
If you already have solar panels, you may be able to add a battery to your existing system. The right solution depends on your panels, inverter, household electricity consumption and battery capacity. For new installations, a solar and battery package can combine generation and energy storage into one complete system.
Choosing the right battery is about more than selecting the largest capacity. Battery size should match your household’s energy usage and when you typically use electricity. Understanding battery cost and comparing battery prices can help you choose a system that suits both your energy needs and budget.
For homeowners, battery storage can be a practical way to use more of the electricity generated by your solar panels during the day. Instead of relying entirely on the grid after sunset, stored energy can be used when your household needs it most.
A battery can also provide backup power during a grid outage, depending on the battery, inverter and system configuration. This can help keep selected essential appliances and circuits operating when the electricity supply is interrupted.
Professional solar battery installation is important to ensure the system is correctly designed, installed and commissioned. An experienced installer can assess your existing system, check battery compatibility and recommend the right configuration for your property.
Here at Easy Solar, we offer quality battery solutions from leading brands including Sigenergy, GoodWe and Fronius. We can recommend the right battery option based on your energy needs, existing solar system and the level of storage and backup power you require.

The right battery size depends on your household’s electricity usage, solar system capacity and how much energy you use in the evening. Easy Solar can assess your energy needs and recommend a suitable battery capacity for your Perth home.
Battery prices vary depending on the brand, storage capacity, installation requirements and compatibility with your existing solar system. Contact Easy Solar for a tailored quote based on your home’s energy needs and installation requirements.
A battery may be worthwhile if you generate excess solar electricity during the day and use more power in the evening. The financial benefits depend on your energy consumption, solar generation, electricity tariffs, battery cost and available incentives.
Yes, many existing systems can be upgraded with battery storage. Compatibility depends on your current inverter, solar panels and system configuration. Easy Solar can assess your existing equipment and recommend a suitable battery solution.
Battery lifespan depends on the brand, the battery chemistry and how the system is used. Manufacturer warranties vary by brand — for example, the Growatt ARK XH battery carries a 10-year warranty. On top of that, Easy Solar provides a 10-year workmanship warranty on its installations.
Yes, many modern battery systems are modular, so extra capacity can be added later as your household’s energy use grows. For example, Growatt’s ARK XH system grows by adding 2.56 kWh modules. Whether your system can expand depends on your battery and inverter configuration, and Easy Solar can assess this for you.
In most cases a battery installation is completed in a day. Installations are generally scheduled within 14 working days of approval, following a free site assessment.
