INSTALL MANUAL
Inverter Communicaon Cable Aachment
a) Run the end of the communicaon cable labeled
“BATTERY” through the smaller compression seal on
the BMS (Master BMS in a parallel install)
b) Plug the communicaon cable into the INV-CAN port
on the baery.
c) The other end of the communicaon cable is labeled
“INVERTER” and connects to the CAN port of the
inverter.
e) Aach the included lugs onto the ends of both posive
and negave 4/0 baery cables (not included) and slide
through the large compression seals. It may be easier to
slide the baery cables through the compression seals
rst and then aach the baery lugs to the baery
cables.
f) Fasten the M8 bolts connecng the baery cable lugs
to the baery terminal busbars using a torque wrench
set to 12 ± 1.2 N.m (106.21 in-lb ± 10.62 in-lb).
g) Reaach the clear plasc covering over the posive and
negave terminals.
h) Screw caps back on the compression seals.

The cable provided has had its pins specically
adjusted for a Sol-Ark inverter. If you need to make
your own cable, you must alter the pin sengs
on the inverter end. Please see pg. 29 for wiring
conguraons for other compable inverter COM
cables.
Baery cables may be installed before or aer steps 3-5. In
all cases, ensure that the baery modules and BMS are all
powered OFF. Bus bars, lugs, bolts, and nuts are included in
each BMS box. You must use the provided hardware.
a) Remove the clear plasc covering from over the
posive and negave terminals.
b) Remove all screws (M8 * 16) from each terminal.
c) Aach the included shorter bus bar on the posive
terminals and reaach the screws (M8 * 16) securing it
into place on the BMS.
d) Aach the included longer bus bar on the negave
terminals and reaach the screws (M8 * 16) securing it
into place on the BMS.

Aer all the baery modules have been successfully recognized
using the “detecon” mode (steps 4 and 4A), change the DIP
switches on the red “Invert set” on the side of the BMS to
match your paired inverter.
