FranklinWH aPower Solar Battery Review 2026: High-Capacity Whole-Home Backup

The FranklinWH aPower series is a standout choice for installers needing high-capacity, reliable residential energy storage. At SunsUpPV, we stock the aPower line because it delivers strong continuous and peak power, excellent scalability, and robust performance — especially for whole-home backup and AC-coupled retrofits.

Key Specifications & Features

• High Capacity — ~13.6–15 kWh usable energy per unit
• Strong Power Output — 5–10 kW continuous with high peak capability for demanding loads (HVAC, appliances)
• Scalability — Stack up to 15 units per aGate for large systems (200+ kWh)
• LFP Chemistry — Safe lithium iron phosphate with long cycle life
• AC-Coupled Design — Ideal for retrofits on existing solar arrays

The aPower works well with compatible automatic backup switches like the EQB Energy Quarterback for seamless operation.
