hazards. The f ll wing safety pr cedures sh uld be f ll wed:
Only c nnect the PCS cabinet t a c mpatible electrical service as defined in the m del specificati ns. The PCS must be
c nnected t a dedicated branch circuit in the main electrical panel.
An external disc nnect switch shall be pr vided in the end installati n by thers f r the AC Grid utput circuit.
CAUTION! This e uipment contains high energy lithium batteries. Qualified and trained pers nnel sh uld
wear pr tective cl thing and equipment when w rking inside the battery cabinet and/ r with battery m dules.
CAUTION! The batteries provided with this system must be charged only by the PCS included as part of the
energy storage system. D n t attempt t charge batteries with any ther charger device r c nnect any
devices directly t the DC battery bus.
Ensure pr per electrical gr unding in acc rdance with c de requirements.
Ensure pr per airfl w path f r active c ling.
Never perate system in a manner n t described by this manual.
Only qualified pers nnel sh uld service this pr duct.
Ensure all c vers are securely fastened after installati n is c mplete.
This pr duct must be st red ind rs in an envir nmentally c nditi ned l cati n pri r t installati n, pr tected fr m rain
and exp sure t any hazard us chemicals.
D n t attempt t perate this pr duct if there is any physical evidence f damage t any f the cabinets r internal
c mp nents.
CAUTION! This e uipment is heavy. Mechanical lifts are rec mmended f r safe installati n.

3 Installation Site Preparation
Bef re installing the pr duct, read all instructi ns and warnings in this manual. This pr duct is wall-m unted nly, and can
be installed b th utd rs (in c mpliance with NEMA Type 3R installati ns) and ind rs, either attached r detached
garages, and ind r l cati ns m re than 5 feet fr m dwelling units. This pr duct is n t t be installed in habitable spaces.
C nsult l cal building c des f r m re details.
AUTION! All electrical installation work should be performed in accordance with local building and electrical codes.
WARNING! Isolate the PCS from all energy sources prior to electrical installation by means of disconnects, breakers
or connectors. Failure to properly isolate either AC or C sources may result in serious injury or death. This system
will generate an AC voltage at the off-grid terminals when C source is applied.
AUTION! The P S cabinet weighs up to 145 lbs. (65 kg), and the battery cabinet weighs up to 320 lbs. (145
kg) with four battery modules installed. Handle with care. The wall t which the system is m unted must be
l ad-bearing rated acc rding t the l cal building c de. Mechanical lifts are rec mmended t p siti n cabinets n the wall
bracket.
NOTE: All interc nnecting cables are limited in length, and designed specifically f r adjacent cabinet m unting using
the manufactured wall brackets.
CAUTION! o not install in direct sunlight. Battery performance is dependent upon operating ambient temperature.
Radiant heat absorbed in direct sunlight will greatly reduce the performance of the battery, and will prematurely
cause degradation of the display indicator panel on the PCS cabinet. The battery modules are rated for operating
temperature range between -10C to +50C.
NOTE: ESS systems installed ind rs may require the installati n f a sm ke alarm r heat detect r specific f r ESS
use. C nsult the l cal building c de f r m re details.
NOTE: This pr duct was n t evaluated in seismic envir nments.
NOTE: All external wiring must be pr tected by metallic c nduit, and all c nduit fittings installed n the ESS
cabinets must be rated Type 3R r better.
3.1 Overview of PCS and Battery components
1. The f rced air c ling f the PCS cabinet is designed t fl w air fr m b tt m t t p.
2. Wall m unting hardware n t
included. The l ad-bearing
wall bracket is pr visi ned f r
M8 hardware. Levelling
brackets are pr visi ned f r
M5 hardware.
3.2 Installation Area Required
to Wall Mount the ESS:
The physical installati n f the cabinets
requires lay ut planning and installati n
f the system c mp nents in the
available installati n space. The
rec mmended installati n height is
driven by the viewing angle f the
display panel n the PCS cabinet.

system. The sl ts acc mm date a M8 (5/16”) b lt diameter.
IMPORTANT! Wall-stud m unting: A minimum f three wall
studs spanned within the width f the m unting rail are
required. A minimum f tw m unting b lts are required per stud
(t p/b tt m).
2. (n t sh wn) Rem ve the battery cabinet fr m the packaging, and
stand the cabinet upright. Rem ve the fr nt c ver.
3. M unt the tw leveling brackets t the back side f the cabinet.
Each side f the cabinet must have a rubber washer in direct
c ntact with the cabinet wall.
4. Lift the battery cabinet nt the wall m unt bracket, aligning the

fasten with the l ck nuts. T rque t 10 – 15 in-lbs.
WARNING! The mounting bolts of the flange
assembly are required to be fully secured, as
they provide the chassis grounding for the battery
cabinet. Torque nuts as shown in the specification
tables provided in this manual.
16. Continuity test: Check the c ntinuity
between the cabinets using an Ohm meter. The
test reading must be zer Ohms at a bare metal
p int inside each f the PCS and battery cabinets.

5.5.3 PCS to BMS communication cable
This cable is specific t the battery m del. Refer t the instructi n that applies nly t the battery m dule suppled.
Terminate the PCS-BMS cable in battery #1 as sh wn bel w. This battery is herein referred t as the “Master” battery
m dule. All ther m dules sync t the master.
1. Terminate the PCS – BMS / C ns le Y cable jumper in the [A/CAN] and [C ns le] p rts f battery #1.
2. R ute the ther end f the cable thr ugh the PCS p rt h le and terminate in the cable in the [BMS OUT] p rt.

6 System Electrical Wiring
Note: This pr duct is capable f pr viding utility interactive and
islanded back up p wer, and can be AC c upled t a utility interactive
ph t v ltaic inverter. Wiring meth ds must be in acc rdance with
l cal electrical c des. The installer is resp nsible f r ensuring that ver-
current pr tecti n is installed and sized appr priately f r the AC grid
and ff-grid utput circuits, in acc rdance with the Nati nal Electrical
C de, ANSI/NFPA 70, Canadian Electrical C de and l cal c des.
All field wiring c nnecti ns t the battery system are at the PCS cabinet nly.
The kn ck ut l cati ns f r c nduit entry int the PCS are categ rized as AC
p wer and signal level circuits.
IMPORTANT! Drilling holes anywhere in the battery or PCS cabinet
renders the warranty null and void. Use the kn ck uts pr vided at the
b tt m face f the PCS cabinet nly! D n t drill h les anywhere in the
battery system. Use c nduit fitting reducers, if applicable.
6.1 AC power connections
Note: The PCS pr vides galvanic separati n between AC and
DC S urces.
AUTION! To reduce the risk of fire, connect only to a
dedicated circuit provided with appropriate branch circuit over-
current protection in accordance with local electrical codes.
WARNING! Improper connection of the wiring panel may
result in equipment damage and cause personal injury.
isconnect all AC and C Sources prior to installation.
Note: The AC utput’s Neutral terminal is n t b nded t
gr und. The Neutral is c nnected t gr und when perating in
backup (stand-al ne) m de.
AC Grid Port:
1. Terminate the AC grid c nnecti n wires as f ll ws:
L = Line
N = Neutral
PE = Gr und.
6.2 External AC Circuit Protection Device
An external AC circuit pr tecti n device, either breaker r fused disc nnect, that is lates all ungr unded c nduct rs, shall
be pr vided by thers f r the AC Grid utput circuit. F r utd r wall m unt installati ns, the disc nnect must be rated f r
utd r use and include fuse pr tecti n f ungr unded c nduct rs (2 p le). The maximum fuse / breaker rating f r the
external disc nnect is determined by the use applicati n f the ESS:
Grid interactive nly perati n (with ut backup): 50 Amp
Grid interactive & backup perati n: 60 Amp
