Now, for the BMS of the system, we need to run a detecon of
how many baery modules have been stacked. Follow the order
of operaons below in careful detail.
a) On the BMS, ip the red “invert set” DIP switches all
UP, #1-6 (this puts the BMS in detecon mode).
b) Power ON the baery modules, starng from the
boom baery module to the top. (Aer you power
ON, a green light should appear)
c) Power ON the BMS. The BMS display will show various
informaon as the system boots.
d) Aer what can take up to 3 minutes, the BMS display
will ash the number of baery modules it detected
within the stack (2-8). Wait 30 seconds aer all
modules are detected before proceeding to the next
step.
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 the BMS are correct.

4a. PARALLEL ONLY: Seng the “Address Set” DIP Switches
This step only applies to installs ulizing mulple Stack’d Series
baeries running in parallel. As menoned in the last step, the
DIP switches on the modules should be set depending on how
many baery modules are within the stack. Those seng do
not change for the baery modules. Note however, that the
address set DIP switches on the master baery stack are set to
#1 UP, with the rest DOWN (#2-6), while the second baery in
parallel’s address set is according to its posion in parallel (#2 is
UP, while #1 and #3-6 are DOWN).
If you are installing more than two stacks in parallel, use the
chart on page 15 for the address set DIP switches. At this point,
all power buons should be pressed OFF.
