FranklinWH
FranklinWH has engineered a highly capable ecosystem centered around their aGate smart controller. By processing the entire home's load through the aGate, the aPower battery appears suitable for true whole-home backup, intelligently shedding non-essential loads during an outage. The 5.0 kW continuous output is solid, and its ability to seamlessly integrate generators alongside solar sets it apart from many competitors in the premium tier.
Because it is AC-coupled, it works with almost any existing solar inverter (SolarEdge, Enphase, SMA), making it a versatile retrofit option. The 13.6 kWh capacity provides a robust baseline, but managing heavy loads during a blackout still requires careful circuit prioritization via the app.
The aPower unit is extremely heavy at 185 kg, requiring robust mounting hardware and a coordinated installation crew. The IP67 rating offers excellent environmental protection, but extreme temperatures will still affect long-term cell health. Verify clearance requirements for ventilation.
