Battery capacity directly impacts how long your solar batteries can power your home. Measured in kilowatt-hours (kWh), capacity indicates the amount of energy a battery can store. For example, a battery with a capacity of 10 kWh can supply a household with sufficient energy for several hours, depending on usage.
If you're researching solar batteries, you probably want to know how much of your house you can power and for how long. The short answer? A typical 13 kWh battery (the size of a Tesla Powerwall 3) can keep your refrigerator, lights, WiFi, phone chargers, and TV running for nearly a full day.
Whole home backup is possible, but it takes a large solar system with around 30 kWh of battery storage. Let’s run through an example scenario of powering essential systems during a 24-hour power outage to get an idea of how much solar and battery capacity you’ll need.
Capacity — the amount of energy a battery can store — is one of the main features that influence how long a battery can power a house during a power outage. Battery capacity is measured in kilowatt-hours (kWh) and can vary from as little as 1 kWh to 18 kWh.
