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™ or Encharge 10™ 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 Enphase Storage System includes the Enphase Encharge Battery(ies) with integrated Enphase Microinverters™. The Enphase IQ Envoy™ gateway

measures PV production and home energy consumption. The Enphase 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 Enphase Enpower™ is

installed at the site.

Five unique installation scenari-

os are shown:

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.

Partial home backup with main load

panel as service entrance and PV

combiner connected to Enpower.

When PV circuits breaker size is

less than 80A, this is the preferred

conguration for partial home backup

with sub-panel.

Partial home backup with main load panel as service entrance and PV combiner connected to sub-panel. 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 Enpower for combiner (solar) connection is left vacant. Self consumption, no Enpower smart switch.

INSTALLATION 1 Plan a location for the Encharge batteries 2 The Encharge housing is NEMA type 3R and can be installed indoors or outdoors. The terminal blocks accepts copper conductors of No. 12 - 8 AWG. Following all local codes and standards: 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 Encharge 3 (single width) or Encharge 10 (triple width) wall mount bracket Follow the instruction below for the bracket you are installing. Encharge 3 — single-width bracket Encharge 10 — triple-width bracket A ) Place the wall-mount bracket on the wall so that the mounting holes in the middle of the bracket align with the center of the stud.

Mount the Encharge Battery(ies) on the wall * WARNING: Risk of injury. Take care when lifting. Each Encharge Battery is heavy (47 kg/ 104 lbs) and requires two persons to lift. * WARNING! Risk of injury and equipment damage. Avoid dropping the Encharge 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 Encharge Battery(ies) from impact damage and improper use.

Install conduit and field wiring 6 Install conduit and field wiring, continued + DANGER! Risk of electric shock. The DC switch must be in the Locked position before performing this step. A ) Remove the sealing plug for entry into the field wiring compartment. If installing only one battery or when installing the last battery in the array, seal up the hole with the supplied sealing plug. B ) Size the conductors (Lines and Ground) to account for voltage rise and to conform to the tables below.
PAGE 7
Cover and energize the system * WARNING: Before energizing, make sure that ALL Encharge Batteries in the system are properly installed and conductors terminated. NOTE: Check the Cover Kit box for updates on cover installation instructions. A ) Check that the field wiring compartment cover(s) for all Encharge Batteries in the system are closed and secured.
