The capacity of your battery storage system can affect whether it qualifies for the federal tax credit, but it does not impact the amount of the tax credit you can claim. To qualify for the tax credit, the battery storage system must have a capacity of at least 3 kilowatt hours, which became a requirement starting in 2023. However, most residential battery installations are larger, typically around 10 kilowatt hours or more, so this minimum capacity requirement is not a concern for most users.
The federal tax credit for qualified battery storage systems from 2022 to 2032 is 30% of the eligible costs, without any maximum size or cost limit. Therefore, the size of the system beyond the minimum capacity does not affect the percentage of the tax credit you can claim. The focus is on ensuring that the system meets the minimum capacity threshold and is used in a dwelling unit in the United States.
