enphase IQ Battery 3T User Manual

QUICK INSTALL GUIDE (Models Encharge-3T-1P-NA and Encharge-10T-1P-NA)
Install the Enphase IQ Battery System
To install the Enphase IQ Battery 3T system or IQ Battery 10T 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, trouble-
shoot, or replace the IQ Battery 3T or IQ Battery 10T.
The IQ Battery system includes the Enphase IQ Battery(ies) with integrated Enphase IQ™ Microinverters. The Enphase IQ Gateway measures PV produc-
tion and home energy consumption. The IQ Battery 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. IQ Battery systems are capable of providing backup power when an Enphase IQ System Controller is installed at the site.
Five unique installation
scenarios are shown:
Whole home backup with IQ System
Controller as service entrance and
PV combiner connected to IQ System
Controller. 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 IQ System
Controller 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 IQ System
Controller 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 to IQ
System Controller.
Partial home backup with main load panel
as service entrance and PV combiner
connected to IQ System Controller. When
PV circuits breaker size is less than 80A,
this is the preferred conguration for partial
home backup with subpanel.
