The Enphase AC Battery is an integrated energy storage system that delivers high performance, superior reliability, modular architecture, and connects safely with standard AC wiring.
Solar production peaks during midday, energy consumption may be highest in the morning and evening. Storage saves the energy you produce for when you need it. Many homeowners find it makes more financial sense to store their extra energy and use it themselves.
Battery chemistry is progressing, allowing higher energy density in smaller, lighter batteries that are also less expensive, safer, cycle better, and are longer-lasting.
Enphase high-performance energy storage solution brings you more intelligence and better value than anything else, with the industry’s lowest cost of entry and best lifetime value. It pairs seamlessly with Enphase microinverters and other solar technologies to help you make the most of your energy.

Storage systems come in two varieties: AC-coupled or DC-coupled. AC-coupled systems connect to a solar array on the AC side, while DC-coupled systems connect on the DC side. DC-coupled systems allow both the solar array and battery to be served by a single inverter. AC-coupled systems offer equivalent efficiency to DC-coupled systems with advantages of flexibility to be more incrementally scalable, more reliability solution can be retrofitted to existing solar installations, and safety with no high-voltage DC indoors. The Enphase AC battery is an example of an AC-coupled system, while Tesla’s Powerwall is an example of a DC-coupled system.
