QUICK INSTALL GUIDE (Models ENCHARGE-3-1P-NA and ENCHARGE-10-1P-NA)
Install the Enphase Encharge Storage System
To install the Enphase Encharge 3™ storage system or Encharge 10™ storage system and the Enphase wall-mount bracket, read and follow all warnings and
instructions in this guide. Safety warnings are listed on the back of this guide. These instructions are not meant to be a complete explanation of how to design
and install an energy storage system. All installations must comply with national and local electrical codes and standards. Only qualied electricians shall
install, troubleshoot, or replace the Encharge 3 or Encharge 10.
The Encharge™ storage system includes the Enphase Encharge Battery(ies) with integrated Enphase IQ™ Microinverters. The Enphase IQ Envoy™ commu-
nication gateway measures PV production and home energy consumption. The Encharge storage system senses when it is optimal to charge or discharge
the battery so that energy is stored when it is abundant and used when scarce. Encharge storage systems are capable of providing backup power when an
Enphase Enpower™ smart switch is installed at the site.

Whole home backup with Enpower
as service entrance and PV combiner
connected to Enpower. This is the preferred
conguration for back up of the entire main
load panel. This conguration supports up
to an 80A breaker for the PV circuit and an
80A breaker for battery storage.
Whole home backup with Enpower
as service entrance and PV combiner
connected to main load panel. This is the
preferred conguration when you back up
the entire main load panel, and the size of
the PV combiner circuit is more than 80A. In
this conguration, the PV combiner circuit
connection space in Enpower is left vacant.
When existing PV combiner circuits are
connected to the main load panel, and you
want to add battery storage to the system,
you can keep the PV combiner connected
to the main load panel and connect only the
battery storage system to Enpower.
