How to choose the capacity of home energy storage battery?

The capacity selection of household energy storage batteries should be determined according to household electricity consumption and expected power outage time. Generally speaking, the energy storage battery capacity of a household can be selected to be 1.5 to 2 times the average daily electricity consumption of the household. For example, if the daily electricity consumption of the household is 10 kWh, then the energy storage battery capacity can be selected from 15 to 20 kWh. In addition, factors such as daylight hours and light intensity need to be considered to ensure that the energy storage battery can be fully charged during charging and provide enough power when needed. It is best to consult a professional solar system installer for customized advice based on your specific circumstances.
