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

Safe

  • Highly stable pouch cells from A123
  • Safety certified by TUV Rheinland
  • No high-voltage DC in system

A solution that’s just right.

The AC Battery’s modular architecture means you’ll get a storage solution that’s exactly what you need: no more, no less, no wasted costs. The system is easy to expand on as your needs change, as your family grows or you add an electric vehicle. Plus, flexible configurations work for any garage.

Installation is as easy as it gets.

The Enphase Energy Solution

Proven technology delivers the most reliable, high-performing system to provide the best return on your investment. Enphase is the smarter choice in solar.

Enphase Microinverters

Located beneath each panel, microinverters convert power right at the source, maximising energy harvest without high voltage power on your roof.

Enphase Envoy

The brains of the system, the Envoy monitors its performance and enables regular software updates, just like with your phone or computer. If you already have solar, you can install the Envoy-S Metered and get AC Battery-ready.

Enphase AC Battery

AC Batteries store excess energy produced during the day so you can use your own electricity when you need it at night or on cloudy days. You can install just one AC Battery to start off with and add more later, and that works with any solar system.

Enphase Enlighten

MyEnlighten provides insight into your electricity production and consumption, shows your CO2 savings and you can share all of it on social media.

Some of the key benefits with Enphase

Reliability, inside and out

Enphase products are designs to deliver more power

Solar your home will love

Every part of the Enphase system is designed to have minimal impact on your home. Wiring and equipment stay out of sight, and the low voltage design boosts safety.

More power from your panels

Enphase microinverters get more power from the same solar panels. This means greater savings for you, and greater environmental impact. Each microinverter connected to a single solar panel so, unlike other types of inverters, if there is a dirty, shaded or problem panel, the rest of the system keeps running smoothly

See your solar savings

You can learn how much power your system is producing at any time from your phone or computer. Watch it work and know you’re saving money, as well as the planet.
