INSTALL MANUAL
This step only applies to installs ulizing mulple Stack’d Series
baeries running in parallel. Aer compleng step 4 for each
baery stack and detecng the number of baery modules, it is
now me for the master BMS to detect the number of paralleled
systems running together. Follow the order of operaons below
in careful detail. At this point, all power buons should be
pressed ON and step 4 should be completed for each individual
stack.
a) On all baeries running in parallel (except for the
master baery), set the red invert set DIP switches to
#1 UP, with DIP switches #2-6 DOWN.
b) On the master baery, set the red invert set DIP
switches to #1 DOWN, with DIP switches #2-6 UP.
c) Turn the power buon of the BMS ON, starng with
the furthest paralleled system from the master baery.
Wait 5 seconds. Then turn the next system in parallel
BMS ON and wait 30 seconds. Repeat and nish by
turning ON the master baery’s BMS last.
d) Aer what can take up to 3 minutes, the BMS display
of the master baery will ash the total number of
paralleled systems detected.
If this number is not correct, check that you’ve powered on
all modules and set their DIP switches correctly. Addionally,
check that the DIP switch sengs on all BMS’s in parallel
are correct. Check that communicaons cables are correctly
inserted between Link A to Link B.
4c. PARALLEL ONLY: Parallel Detecon Mode
This step only applies to installs ulizing mulple Stack’d Series
baeries running in parallel. At this point, all power buons
should be pressed OFF.
a) Use a standard Ethernet cable to connect the stacks.
There is an extra Ethernet cable included in the
packaging for this purpose.
b) Connect the cable to the “Link A” port of the master
BMS
c) Connect the other end of the cable to “Link B” port of
the paralleled BMS
d) For installs with more systems in parallel, repeat the
paern of Link A to Link B
