To qualify for federal tax credits, battery storage systems must meet the 3 kWh minimum capacity requirement. While the tax credit amount (currently 30% through 2032) applies regardless of brand, some top-performing systems recognized in 2025 include:
Bluetti EP900
Named CNET’s best solar battery of 2025, this modular system offers high power output (9.6 kW continuous) and flexible capacity expansion. While tax credits depend on IRS eligibility criteria, its capacity options (up to 19.8 kWh with expansion) easily exceed the 3 kWh threshold.
SunPower SunVault
Features a standout unlimited cycle warranty and large capacity options (13-39 kWh). As a product from a solar industry leader, it’s often bundled with solar installations that maximize combined tax credits.
Savant Power Storage 20
Designed for smart home integration with 12.5 kW continuous output, though it’s pricier and less modular than competitors.
Key Tax Credit Requirements:
- Eligibility: Must be installed in U.S. homes (primary or secondary residences; rentals excluded).
- Documentation: Requires IRS Form 5695 for claim processing.
- Capacity: Minimum 3 kWh (all listed brands meet this).
Always confirm system specifications with manufacturers and consult tax professionals for credit compliance. Current top brands combine adequate capacity with performance features that enhance long-term savings when paired with tax credits.
