Enpower™ smart switch

In stock

Enpower™ smart switch is a part of the Enphase Ensemble™ energy management system which consolidates interconnection equipment into a single enclosure and streamlines grid-independent capabilities of PV and storage. It provides a consistent, pre-wired solution for residential solar + storage applications. During outages, it isolates your solar system from the grid and connects the storage. 

Note: The prices here are for equipment only. They do not include installation, permitting and possible panel rewiring costs. Energy storage installations require a significant amount of electrical work, and a significant amount of time from your installer. While equipment costs typically account for 50-60% of the cost of an energy storage system, the installation itself – i.e., the amount of electrical work required and where you find your installer – also plays a large role in the overall cost of the system.

A complete storage system consists of Encharge 10, Encharge 3, Enpower smart switch, Enpower main and circuit breakers, communication kit with cell modem, and soft starters. Each need to be procured separately.

Enphase Storage systems should be installed by a trained and certified Enphase Installer. All self-installers are required to complete an Enphase Storage certification course and system design review in order to successfully commission a system.
