FranklinWH Complete Energy Ecosystem

FranklinWH delivers two distinct 15kWh battery solutions: the aPower S integrates solar inverter and battery in one unit with four independent MPPTs for direct DC connection, while the aPower 2 provides AC-coupled flexibility for retrofit installations and grid-tied applications. Both scale to 225kWh and deliver whole-home backup power.

aPower S Hybrid Integration: Integrated 11.5kW inverter with 4 MPPTs
aPower 2 Flexibility: AC-coupled design for retrofitting existing solar systems
Extreme Climate Performance: operates reliably from -4°F to 131°F
Scalable Energy Storage: Expand from 15kWh to 225kWh per aGate
Whole-Home Backup Power: 10-11.5kW continuous output handles 5-ton A/C startup plus simultaneous home loads

FranklinWH aPower S Hybrid Battery System

FranklinWH aPower S Hybrid Battery System

15 kWh all-in-one battery with built-in 11.5 kW inverter and 20 kW direct solar input

The aPower S integrates 15 kWh of lithium iron phosphate storage with a built-in 11.5 kW inverter and four independent MPPT charge controllers in a single unit. Supporting up to 20 kW of direct solar input, this hybrid system delivers 90.5% round-trip efficiency while powering your entire home including HVAC, well pumps, and major appliances. Front wiring access and IP67-rated outdoor enclosure simplify installation, while integrated thermal management with heating blankets ensures reliable operation from -4°F to 131°F.

Direct Solar Integration

Four independent MPPT charge controllers with 20 kW total capacity connect solar arrays directly to the battery, eliminating external charge controller equipment and simplifying system design.

High Power Density

Delivers 11.5 kW continuous output with 15 kW surge capability from a single 15 kWh unit, providing whole-home backup for HVAC systems, well pumps, and major appliances.

Simplified Installation

Front wiring access and all-in-one integrated design reduce installation complexity and labor time compared to separate battery and inverter component systems.
