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.
