The U.S. federal tax credit for battery storage requires a minimum capacity of 3 kilowatt-hours (kWh) to qualify for the Residential Clean Energy Credit. Here’s how this requirement impacts eligibility:
- Threshold for qualification: Batteries below 3 kWh cannot claim the credit. Most residential systems (often 10+ kWh) exceed this minimum, but smaller installations must verify capacity.
- Cost considerations: While the credit itself is uncapped (30% of total eligible costs, including labor), the 3 kWh minimum ensures only substantial storage systems qualify, preventing very small or incidental installations from benefiting.
- Eligibility scope: Systems must be installed in U.S. residences (primary or secondary homes), but rental properties are excluded.
The capacity rule ensures the credit supports meaningful energy storage investments without arbitrary size limits, while labor costs and equipment qualify for the same percentage. Taxpayers must subtract rebates/incentives from the total cost before calculating the credit.
