Enpower smart switch
The Enpower smart switch senses when the grid goes
down and seamlessly transitions the home from grid
power to backup power. Enpower disconnects the grid
and powers the backup loads using the Encharge storage
system, PV system, and the electrical service panel that
houses the circuits that are powered during a grid outage.
Enpower serves as the microgrid interconnect device (MID)
as required by the National Electric Code (NEC) to operate
without grid power. And its neutral forming transformer
(NFT) provides the neutral required for electrical
operations in North America to support 120V and 240V
appliances. Enpower communicates with the Envoy
through wireless signals.
Encharge batteries
The Encharge storage system performs two critical
functions in your system. The batteries, internal to
Encharge, store energy for later use or for use during
a power outage. The IQ 8X-BAT microinverters in the
Encharge units provide the voltage and frequency
necessary for the operation of your solar array and the
electrical circuits in your home during an outage. The IQ
8X-BAT microinverters converts your harvested energy
into usable AC electricity for your house. Encharge
communicates with the Envoy through a mesh network
of wireless signals.
