Source data reviewed 2026-08-12
Suitable Scenarios
  • Whole-home backup scenarios without a critical loads panel
  • Retrofitting battery storage to any existing solar inverter
  • Integration with standby generators
May Be Less Suitable When
  • Small apartments or tight utility rooms
  • Users looking for native DC-coupled efficiency

Planning Analysis

FranklinWH utilizes the aGate smart controller to process home loads, making the aPower battery suitable for whole-home backup scenarios where it can shed non-essential loads during outages. The 10.0 kW continuous output provides a high baseline capability, and it integrates generators alongside solar input.

Practical Considerations

As an AC-coupled unit, it works with most existing solar inverters (SolarEdge, Enphase, SMA), making it a versatile retrofit option. The 15.0 kWh capacity provides a robust baseline, but managing heavy loads during a blackout requires circuit prioritization.

Installation Notes

The aPower 2 unit is heavy at 185 kg, requiring robust mounting hardware and a coordinated installation crew. The IP67 rating offers environmental protection. Verify clearance requirements for ventilation.
