A home battery can vary in storage capacity depending on the specific model and its power. Home batteries are used to store excess electricity generated by solar panels or other renewable energy sources, so it can be used later when energy demand is higher or when there is no direct energy production.

The storage capacity of a home battery is usually expressed in kilowatt-hours (kWh). The range can vary from a few kilowatt-hours to several dozen kilowatt-hours, depending on the battery system chosen. Larger batteries generally have a higher storage capacity, but they can also be more expensive.

It is important to note that the storage capacity of a home battery is not equal to the amount of energy it can deliver. The usable energy that can actually be drawn from a home battery can vary depending on various factors, such as the system settings, the efficiency of the battery, and the load connected to it.

It is advisable to look up specific information on the storage capacity and performance of a particular brand and model of home battery to obtain a more accurate estimate of how much energy it can store.
