What actually differs

  • More usable capacity: the Enphase IQ Battery 10C offers 10 kWh vs 5 kWh, so at that size it carries more of your home for longer per charge.
  • More continuous power: the Enphase IQ Battery 10C sustains 7.08 kW vs 3.84 kW, which matters for running big loads like an AC at once.

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.
