The FranklinWH aPower 2 is an all-in-one AC-coupled home battery system combining a 10kW inverter and 15kWh lithium iron phosphate (LFP) battery in a single wall-mounted cabinet. Designed for professional solar installers, it integrates into new or existing grid-tied solar systems without requiring a DC-coupled inverter swap, making it one of the most versatile whole home battery backup solutions available today.
The aPower 2 handles heavy residential loads including HVAC, electric ranges, and EV chargers, and delivers seamless automatic transfer during grid outages. Its AC-coupled architecture means it pairs with virtually any string inverter brand on the market, eliminating the need for complete system redesigns on retrofit jobs.
- Inverter Output: 10kW continuous AC output
- Battery Capacity: 15kWh usable (LFP chemistry)
- Scalable Storage: Expand up to 225kWh by stacking additional aPower units
- Applications: Grid-tied, off-grid, self-consumption, and time-of-use optimization
- Transfer Time: Seamless automatic backup switching during outages
- Certifications: UL 9540, UL 1741, IEEE 1547
- Warranty: 15-year limited warranty
- Installation: Wall-mounted, indoor or outdoor-rated enclosure
The aPower 2 supports self-consumption optimization and time-of-use rate management, helping homeowners reduce utility bills in NEM 3.0 markets. Its closed-loop communication with the aGate X energy management device provides precise load control, generator integration, and smart circuit management — all configurable via the FranklinWH app.
For installers, the AC-coupled design means simplified permitting, no string inverter compatibility issues, and the ability to add storage to existing solar installations in a single trip. LFP chemistry provides a safer, longer-cycle-life alternative to NMC batteries, with the 15-year warranty backing long-term project confidence.

Frequently Asked Questions — FranklinWH aPower 2
What battery chemistry does the aPower 2 use?
The FranklinWH aPower 2 uses Lithium Iron Phosphate (LFP / LiFePO₄) chemistry — the safest, longest-lasting lithium chemistry for home energy storage. LFP is thermally stable, rated for thousands of cycles, and safe for indoor installation in living spaces.
Does the aPower 2 require the FranklinWH aGate X?
Yes. The FranklinWH aGate X energy management gateway is required to operate the aPower 2. The aGate X manages all communication between the aPower 2 battery, solar inverter, grid, and loads. It is sold separately.
How many aPower 2 units can I connect?
Up to 5 aPower 2 units can be connected to a single aGate X, providing up to 75kWh of total storage capacity. This makes the aPower 2 one of the most expandable residential battery systems available.
How loud is the aPower 2?
The aPower 2 uses passive cooling with no fans, operating at just 30 dBA — quieter than a refrigerator. It can be installed in living areas, garages, or utility rooms without noise concerns.
Can the aPower 2 be installed indoors?
Yes. The aPower 2 is designed specifically for indoor installation. Its passive cooling, LFP chemistry, and quiet operation make it suitable for garages, utility rooms, and even finished living spaces. Always follow local code requirements for clearances.
What warranty does the FranklinWH aPower 2 carry?
The FranklinWH aPower 2 carries a 12-year warranty — one of the longest in the residential battery market. As an authorized FranklinWH distributor, Solwel supports warranty claims directly. Call us at (346) 432-4228.
