Home > Solar Batteries
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 solar 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 solar 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 solar panels, inverter, household electricity consumption and battery capacity. For new installations, a solar and battery package can combine solar 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 solar battery cost and comparing solar battery prices can help you choose a system that suits both your energy needs and budget.
For Perth homeowners, solar 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 solar energy can be used when your household needs it most.
A solar 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 solar system, check battery compatibility and recommend the right configuration for your property.
Here at Easy Solar, we offer quality solar 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.
