Home batteries can help keep the lights on when the power goes out, but you'll need to find the right size battery for your home. Your battery's capacity tells you how much energy it can.
Home battery storage capacities are pretty varied, but the average home battery capacity is likely going to be somewhere between 10 kWh and 15 kWh. Home batteries can help keep the lights on when the power goes out, but you'll need to find the right size battery for your home.
What is a good battery capacity?
Medium Households (3-4 People): For families of three to four, aim for a capacity between 10-15 kWh. This accommodates additional energy demands from appliances like washing machines and microwaves. Large Households (5+ People): Larger families often consume more energy. A battery capacity of 15-20 kWh or more is recommended.
You'll also need to factor in the length of the outage. The average American household uses around 30 kWh per day, so 10 kWh should meet many of your energy needs for a good portion of the day unless you are running large appliances. What is the average size of a home battery?
Large Households (5+ People): Larger families often consume more energy. A battery capacity of 15-20 kWh or more is recommended. This covers extensive use of electronics, heating, and cooling systems. Every household has unique energy demands. You may require a tailored approach based on specific circumstances.
What size solar battery do I Need?
Small Households (1-2 People): If you live alone or with one other person, a solar battery with a capacity of 5-10 kWh typically suffices. This size handles daily energy consumption from essential appliances like refrigerators and lights. Medium Households (3-4 People): For families of three to four, aim for a capacity between 10-15 kWh.
How are batteries sized?
Batteries are "sized" based on their energy storage capacity. Battery capacity is the amount of energy your battery can put away into storage to be used for later. The larger the capacity, the more energy you can stash away. It's measured in kilowatt-hours (kWh), which is a measurement of energy used over a period of time.
