  • Page 4: Contents Of The Box

    Contents of the Box Inside each box is the 5.14 kWh battery (51.2 V , 100 A capacity), negative and a positive DC cable with amphenol connectors (battery side) and M8 lugs (inverter / DC busbar side). Each box also contains a pin-to-pin CAT cable for communication to either the inverter or between the battery units.

  • Page 5: Stacking

    Stacking The Z-Range battery can be stacked in 3 different configurations: • Standing on its back • Stacked with brackets • Stacked in a cabinet (each battery is 3U in height) Figure 2: 4 Stacked Z-Range Battery Modules A maximum of 4 units can be stacked when using the brackets. It is recommended to use two or more stacks when more than 4 units are installed.

  • Page 6: Wiring

    Wiring Before connecting the DC cables, please ensure the polarity of the connections are correct. Note that it is required to have a DC disconnect between the battery and the inverter. DC Connections The Amphenol connections on the battery can only sustain 100 A output. There are two different ways to connect the battery in parallel.

  • Page 7: Communication

    Wiring methodology #2: Daisy chain the DC connections, from bottom to top. This wiring methodology limits the current output to the maximum recommended output of a single battery, but increases the available capacity. Figure 5 illustrates how to connect the batteries with this method. For this configuration we recommend that the provided cable from the master box be connected to the top unit and the DC disconnect.
  • Page 8 The communication cables between the units must follow the address of the units. Address 1 needs to be connected to Address 2, and Address 2 is connected to Address 3, as mentioned in Table 3. The CAN connection between the GX device and the battery connects on the CAN port of the master unit.

  • Page 9: Master Configuration

    Master Configuration The configuration of all the Z-Range units can be set to either be the master or a secondary in a stack. The dip switches are used to change the address of the unit in the stack. Table 3 illustrates the arrangement of dip switches to configure each individual unit in a stack.

  • Page 10: Startup Procedure

    Startup Procedure Refer to Table 1 and Figure 1 for the port and switches layout. Double-check polarity of the DC connections between the battery and inverter. Ensure the fuses to the battery are completely open or removed. The communication cable to the GX device/inverter must also be removed.
