The Enphase
Storage System

A smart battery meets powerful software.

Welcome to smarter storage, powered by the new Enphase AC Battery​

Our high-performance energy storage solution brings you intelligence and better value than anything else, with the industry’s safest and lowest cost of entry. It pairs seamlessly with Enphase microinverters and other solar technologies to help you make the most of your energy.

Enphase storage solutions

Like bread and butter, black and white, sun and sand — solar and storage are a perfect pair. Storage addresses a fundamental problem of solar energy: while solar production peaks during midday, energy consumption is highest in the morning and evening. With storage, you can save the energy you produce for when you need it most.

The energy storage solution you've been waiting for.

Modular with low upfront cost

  • More affordable than other storage options
  • Simple installation keeps extra costs low
  • Modular for a solution that’s exactly what you need

High performance

  • 96% round-trip efficiency
  • Optimized for predominent application of 1 cycle per day
  • Most usable capacity (100% D.O.D.)
  • TOU application: Multiple time of use cases supported

High reliability

  • Lithium iron phosphate chemistry from A123 for long cycle life
  • Minimum 10-year expected life
  • No single point of failure
