A home battery can vary in storage capacity, depending on the specific model and its power. Home batteries are used to store excess electricity produced 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 chosen battery system. 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 extracted from a home battery can vary depending on several factors, such as the system settings, the battery's efficiency, and the load connected to it.

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