A solar battery is a battery that stores energy from a solar PV system when panels absorb energy from the sun and convert it to electricity through the inverter for your home to use. A battery is an additional component which allows store energy produced from your panels and use the energy at a later time, such as in the evening when your panels are no longer producing energy.

For an off-grid system, your solar PV system is connected to the electricity grid, which allows your home to continue to receive electricity if your panels aren’t producing enough to meet your energy demands. When your system production is more than your energy consumption, the excess energy gets sent back to the grid, you will get a credit on your next electricity bill which will reduce your payment amount with hybrid inverter system. But for those who are off-grid or would rather store the excess energy themselves instead of sending it back to the grid, solar batteries can be a great addition to their solar PV system.

When choosing the type of battery to use for energy storage, consider the following:

Battery life and warranty
Power capacity
Depth of discharge (DoD)
Widonpower is working with the longest cycles Lifepo4 cells and generally battery lifespan from five to 15 years, warranties for batteries are stated in years or cycles. ( 10 years or 6,000 cycles )

Power capacity refers to the total amount of electricity that the battery can keep.Widonpower Solar batteries are usually stackable, meaning you can have multiple battery storages at home to increase capacity.

Battery DOD measures the degree to which a battery can be used relative to its total capacity. If a battery has a 100% DoD , means you can use the full battery storage amount to power your home. Widonpower battery encourages with 80% DOD for the purpose of longer battery lifespan cycles while lead acid battery has quite a low DOD and outdated.
