What actually differs

  • More usable capacity: the FranklinWH aPower 2 offers 15 kWh vs 10 kWh, so at that size it carries more of your home for longer per charge.
  • More continuous power: the FranklinWH aPower 2 sustains 10 kW vs 7.08 kW, which matters for running big loads like an AC at once.
  • Efficiency is not apples to apples here: the FranklinWH aPower 2 quotes 90% (grid to battery to load (AC round trip)) and the Enphase IQ Battery 10C quotes 90% (AC round trip (DC round trip is 96 percent)), so do not read the raw numbers as a direct ranking.

Which one pays off is a numbers question.

Neither spec sheet tells you the payback in your home. That comes from your rate plan and incentives.
