FranklinWH Home Energy Management System is an innovative smart home energy solution. It allows customers to store energy, manage their energy sources more efficiently, and take full advantage of their solar systems. The three primary components of the FranklinWH system are aGate, aPower Sand FranklinWH App .
System bundle includes:
- 1 x aPower S
- 1 x aGate
Application scenarios:
- New solar project: solar + battery
- Existing solar add solar energy storage for retrofit
- Backup power for outages
- Time-of-use optimization
- Off-grid living (with appropriate system design)
The aPower S + aGate solution can connect PV up to 20kW, 15 units parallel per one aGate to get maximum 225kWh.
aPower S product review
The aPower S combines a 15 kWh LFP battery, 11.5 kW continuous output, 20 kW direct solar input, and four built-in MPPTs in an integrated All-in-One solar and storage system . Expandable up to 225 kWh per aGate, the system supports DC-coupled solar, AC coupling with the FranklinWH System, generator or V2L integration, and indoor or outdoor installation. The load start capacity up to 185A LRA, which can provide whole home backup with a single battery or parallel units. It provides a 60 MWh throughput or 15-year warranty, helping users to easily achieve reliable energy independence and freedom over the long term.
aPower S delivers a unified energy ecosystem with unmatched efficiency, higher return on investment (ROI), and lower lifetime costs compared to conventional systems. Its fully integrated design enables direct solar connection, maximizing solar energy capture, storage, and utilization.
