Included Package Contents
After receiving the system, please ensure that all the following components are not lost or damaged. Contact HomeGrid Support if any components are missing or damaged.
Battery Cable Guide
Each system will include positive and negative battery terminal lugs (measuring 3/8 inches, suitable for 4/0 cable). These terminal lugs do not come connected to a cable. Make sure to use the correct cable gauge for the intended system configuration being installed (Use 4/0 cable to anticipate potential system expandability), along with the supplied battery terminal lugs. While the distance limits may vary per installation, anticipate a drop in voltage after 20 feet.
This guide is specifically for a Gen 3 (3″” generation) Stack’d Series system. The easiest way to tell if your system is a Gen 3 is to look for the gold Wi-Fi antenna port on the side of the BMS. All Gen 3 BMS’s have a Wi-Fi antenna port.
1. Unpack and Identify Included Hardware a) Keep the hardware
• Each BMS ships with a packet of cables and hardware (see above).
• Each battery module ships with a bag of brackets (see above).
b) Open the BMS/Base box first. Have the base on the ground and in position before you start unboxing and stacking your battery modules.
2. Stack Modules + Remove Side Panels a) Lift the battery modules with two people (each module is 110 lbs).
b) Remove the protective black covers off each of the battery modules and stack the first battery module on top of the gray base.
c) Stack the battery modules on top of each other. As you stack, remove the side panels on each battery module, giving access to the power buttons and DIP switches for future steps. Be careful with the pins of the connection port on each module when stacking.
d) Stack the gray BMS on top of the battery modules and remove the side panel, giving access to the battery cable terminals, DIP switches, and various ports necessary for installation.
e) The smallest configuration possible is (2) 4.8 kWh modules, for a total of 9.6 kWh. The maximum configuration within a single stack is (8) 4.8 kWh modules, for a total of 38.4 kWh. (You can parallel up to
(15) 38.4 kWh systems, for a total of 576 kWh’s)
Initial DIP Switch Settings The BMS and battery modules use DIP switches to operate and perform several functions- without certain DIP switch settings, the system will not operate as intended. These DIP switches are utilized to identify and orient each module in the stack, facilitate communication between components, connect to Wi- Fi, check installed firmware, and connect to specific inverters. Please make sure when setting each DIP switch, that the DIP switch is completely pushed to the up or down position. Power cycling the BMS is required whenever the DIP switch settings are changed when the BMS is ON. This is to ensure that the BMS is operating in the intended mode configured for, as indicated by the position of the DIP switches.
Incorrect DIP switch settings in general can cause:
• Error codes
• Incorrect number of batteries icons blinking on BMS
display screen
• Modules not powering on
The DIP switches on the BMS have many functions, including:
• Enabling ‘Hardware Detection Mode’ for detecting # of
battery modules installed.
• Enabling ‘Firmware Detection Mode’ for checking
currently installed firmware on the stack (BMS, Battery
Modules)
• Enabling ‘Wi-Fi Connection Mode’ to allow completing
setup for remote monitoring via the HomeGrid App
(Code 56).
Enabling ‘Connection Status Mode’ for checking the
‘online status’ (Code 60).
• Enabling ‘Parallel Detection Mode’ for systems being
configured in parallel (Stacks 2-15).
The DIP switches on the battery modules function to:
• Identify and orient the module according to its position
in the stack.
Set the Module Address Set DIP Switches
The DIP switch settings on the battery modules should be set
according to their position in a stack. For ease of simplicity, we
recommend that you address the bottom-most module on the
base as battery Module 1 and continue upward in this format
until the last module for your given configuration. This method
makes future expansion of the system easy, as additional
modules can be added to the top and addressed accordingly,
without having to move or change the DIP switch address of
the original modules. See chart for recommended numbering
sequence and the associated DIP switch settings for each
module.
The DIP switches on the modules should be set depending on
how many battery modules are within the stack. Ensure that
the battery modules and BMS are not powered on as you are
making these DIP switch changes. Once you have set the DIP
switches to the correct position for every battery module (see
Address Settings diagram on Install Manual page 11) and set the
correct DIP switches on the BMS’s address set (all down, except
1- see Detection Mode diagram on page 11), you can move to
step (4).
At this point, all power buttons should be pressed OFF.
a) On the BMS, flip the red “invert set” DIP switches all
UP, #1-6 (this puts the BMS in detection mode).
b) Power ON the battery modules, starting from the
bottom battery module to the top. (After you power
ON, a green light should appear)
c) Power ON the BMS. The BMS display will show various
information as the system boots.
d) After what can take up to 3 minutes, the BMS display
will flash the number of battery modules it detected
within the stack (2-8). Wait 30 seconds after 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. Additionally,
check that the DIP switch settings on the BMS are correct.
4a. PARALLEL ONLY: Set the “Address Set” DIP Switches
This step only applies to installs utilizing multiple Stack’d Series
batteries running in parallel. As mentioned in the last step, the
DIP switches on the modules should be set depending on how
many battery modules are within the stack. Those setting do
not change for the battery modules. Note however, that the
address set DIP switches on the master battery stack are set to
#1 UP, with the rest DOWN (#2-6), while the second battery in
parallel’s address set is according to its position 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 Install Manual page 13 for the BMS address set DIP
switches. At this point, all power buttons should be OFF.
