    Custom RJ45 cable
    No custom cable is needed. 

    BMS00
    Connect the master battery’s “CAN” port to the inverter’s “Battery CANBus” port (outdoor-rated only) or the “CAN” port (indoor-rated models).

    Turn on Batteries
     Turn on the batteries using the breaker labeled “Master Switch.”

    BMS_Err_Stop
    if you wish the system could fault on battery communications loss.

    Alert
    IMPORTANT NOTICE:
    The battery module is NOT weight bearing and is not designed to support the weight of other battery modules. Do not place battery modules on top of one another without using proper racking or cabinet
    solutions. 

    Battery Module Terminations
    Battery Module Terminals Torque: Max of 7.5 Nm (5.5 ft/lbs)
    There are two positive and two negative terminal connectors on the module. A 400A busbar connects the positive and the negative terminals on the inside of each 
    battery module.

    Home Run Wiring
    It is recommended to land the home run conductors in the following orientation.


    Battery Communication Wiring
    The can-bus port on the HOST battery shall be connected with the corresponding connection to the CAN bus on the PCS/inverter (blue cable). There are two RS485 connectors on each module for module to module connections.  When connecting the communications cables they shall be connected as seen by the black cables drawing in Figure 3. Continue down the string with alternating port connections. 


    Improper Connection Methods:
    DO NOT REVERSE POLARITY BY CONNECTING POSITIVE TERMINALS TO NEGATIVE TERMINALS.
    DO NOT CONNECT MODULE TO MODULE USING A SINGLE TERMINAL CONNECTION.


    SINGLE MODULE THROUGH 8 MODULE INSTALLATION
    NOTE: PRIOR TO THE INITIAL INSTALL, SET THE TOGGLE SWITCHES APPROPRIATELY  
    BEFORE TURNING ON THE BREAKER.  WHEN ADDING MODULES TO AN EXISTING INSTALLATION, TURN OFF THE BREAKER, SET THE TOGGLE SWITCHES APPROPRIATELY, WAIT 20 SECONDS, TURN THE BREAKER ON. 
    Alert

    NOTE: WITH THE 8-BIT LFP MODULES, DO NOT CONNECT MORE THAN 16 MODULES IN PARALLEL. IF YOU ANTICIPATE NEEDING MORE THAN 16 MODULES IN PARALLEL, USE  ONLY THE 6-BIT LFP-LV MODULES





    PRE-COMMISSIONING CHARGING
    Battery may arrive at a low state of charge. It is a good practice to individually charge all batteries to a full charge using a 48V charger that is capable of CC/CV (Constant Current / Constant Voltage)

    CHARGE VOLTAGE AND CURRENT
    The Recommended Charge Voltage for the modules are as follows


    MULTI-MODULE EQUALIZATION RECOMMENDATION 
    In circumstances where the modules are not able to get to a full charge for a few days, the modules may become slightly unbalanced. Over time the SOC of each module may drift. In order to mitigate these situations, Powersync recommends setting the battery system to perform an equalization for 60 minutes at least once every 7 days.  The recommended voltage for the 60 minute equalization are as follows
