The selection of battery type and capacity is related to the power supply capacity and economic benefits of the system. The choice of battery capacity needs to consider the different demands of specific application scenarios.
If you use 8 kilowatt hours (kWh) per day, then you’ll need a battery with a capacity of at least 8 kilowatts (kW) to provide all of your energy needs during the day. Keep in mind that you won’t always be at home though, so you could get away with a smaller battery. What size solar battery for solar panels?
This capacity will allow the solar system to efficiently charge it. 5 kW solar system with a battery — If your home has a 5 kWp solar system, you’ll want a battery capacity of between 9.5–10 kW. Keep in mind that you’ll want to use most of the electricity you generate during the day for charging your battery
That’s because you don’t want to actually use a battery’s entire capacity, as this can damage it. The usable capacity is called depth of discharge (DoD), and most modern batteries have a DoD of between 90 and 95%. Most storage battery capacities range from 1–13 kilowatt hours (kWh) and you’ll typically spend more money for larger capacity.
