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.

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.

Partial home backup with main load panel as service entrance and PV combiner connected to subpanel. This is the preferred connection configuration for partial home backup using a subpanel when the PV circuit breaker size is more than 80A. The space available in IQ System Controller for combiner (solar) connection is left vacant. (optional) Self consumption, no IQ System Controller.

INSTALLATION 1 Plan a location for the IQ Batteries The IQ Battery housing is NEMA type 3R and can be installed indoors or outdoors. The terminal blocks accepts copper conductors of No. 14 - 8 AWG. A ) Following local standards, choose a well-ventilated location where the ambient temperature and humidity are within -15° C to 55° C (5° F to 131° F) and 5% to 100% RH, non-condensing, preferably out of direct sunlight.

Install the IQ Battery 3T (single width) or IQ Battery 10T (triple width) wall mount bracket Follow the instruction below for the bracket style (single-width or triple-width) you are installing. * WARNING! Risk of injury and equipment damage. Attach the wall mount to the wall so that it is no more than five percent from vertical.
PAGE 5
6 Prepare for field wiring Mount the IQ Battery(ies) on the wall * WARNING: Risk of injury. Take care when lifting. Each IQ Battery base unit is heavy (40.5 kg/ 89.3 lbs) and requires two persons to lift. * WARNING! Risk of injury and equipment damage. Avoid dropping the IQ Battery(ies). Doing so may create a hazard, cause serious injury, and/or damage the equipment. * WARNING! Risk of injury and equipment damage. Protect the IQ Battery(ies) from impact damage and improper use.

7 Install conduit and field wiring (continued) C ) Connect each wire in the field wiring compartment to its corresponding conductor (Lines and Ground). Each terminal accepts two 14-8 AWG conductors (11mm/7/16 inch strip length). Tighten to 1.6 Nm (14 lb-in). 2 1 Tab 1 and 2 to be broken Tab 2 to be broken D ) If installing an IQ Battery 10T, secure the inter-connection cable assembly between the IQ Battery units.

8 Cover and energize the system (continued) B ) Turn ON the AC power first (branch circuit protection) and then turn ON the DC switches of the IQ Batteries. NOTE: Do NOT leave the IQ Battery unit’s DC switch in the ON position for any extended period of time (such as overnight or for more than 24 hours) unless IQ Battery is commissioned (communicating with IQ Gateway), connected to AC, and has passed functional testing and is operational.

9 Disassembly of the IQ Battery Cover (continued) CONFIGURE and ACTIVATE A ) Use the Enphase Installer App to commission the IQ Battery(ies). Once connected to the IQ Gateway, refer to the Enphase App help topics for more information. B ) After the IQ Gateway has detected the IQ Battery(ies), the IQ Battery LEDs operate as described in the following section. OPERATION a IQ Battery 10T Cover NOTE: Only for reference purpose, the IQ Battery 10T Cover image is shown above for unlocking.

SAFETY IMPORTANT SAFETY INSTRUCTIONS. SAVE THESE INSTRUCTIONS. This guide contains important instructions that you must follow during installation and maintenance of the Enphase IQ Battery(ies). Failing to follow any of these instructions may void the warranty (enphase.com/warranty). In Case of Fire or Other Emergency In all cases: • If safe to do so, switch off the AC breaker for the IQ Battery circuit, and if an isolator switch is present, switch off the AC isolator for the IQ Battery circuit.
