What is the Battery Storage Sizing & How does it work?
Battery storage sizing is crucial for ensuring that your home has a reliable power supply during outages or when renewable energy sources like solar panels are not generating electricity. The size of the battery depends on several factors, including the daily energy consumption of your household, the desired hours of autonomy (how many hours you want to be able to operate without charging), and the efficiency of the battery system.
The formula to calculate the required battery capacity in watt-hours (Wh) is:
Capacity\ (Wh) = Daily\ Energy\ Consumption\ (Wh/day) \times Hours\ of\ Autonomy
Capacity = Battery capacity in watt-hours
Daily Energy Consumption = Total energy used by the household in a day
Hours of Autonomy = Desired hours of power supply without charging
Daily Energy Consumption = Total energy used by the household in a day
Hours of Autonomy = Desired hours of power supply without charging
For example, if your daily energy consumption is 30 kWh and you want to have 24 hours of autonomy, the required battery capacity would be:
