The capacity of a typical home battery is measured in kilowatt-hours (kWh). Kilowatt-hour is a unit of electrical energy and indicates how much energy the battery can store or supply over one hour. Therefore, the capacity of a home battery determines how many kilowatt-hours of electrical energy it can contain.

The capacity of home batteries can vary and is dependent on the specific model and brand. Small home batteries typically have a capacity of a few kilowatt-hours, while larger models can have capacities ranging from tens to even hundreds of kilowatt-hours.

The capacity of a home battery is a crucial factor when choosing the right system because it determines how long the battery can supply electrical energy before it needs to be recharged. It is an important consideration to meet the energy needs of a household and to ensure autonomy during power outages.
