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.

Five unique installation

scenarios 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 subpanel.

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 Enpower for combiner (solar) connection is left vacant. Generator (reserved for future use¹) 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 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
Mount the Encharge Battery(ies) on the wall * WARNING: Risk of injury. Take care when lifting. Each Encharge battery base unit is heavy (44.2 kg/ 97 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 ) If not already done, use a Phillips screw driver to loosen the screws securing the field wiring compartment cover and remove the cover. Keep the cover and screws handy as you will need them later. E ) Using the conductors and suitable conduits, connect the AC disconnect and the first adjacent Encharge Battery.
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 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.
