Contents of the Box
Inside each box is the 5.14 kWh battery (51.2 Vnom , 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.
Handling the Battery
Work on the battery should be carried out by qualified personnel only.
Please use the provided handles to lift and move the battery. Please handle the battery with
care as the battery is sensitive to mechanical shock.
Ports used During Operation of the
Battery
Figure 1 shows the ports that are used during the operation of the battery. Please pay close
attention to which ports are used and connected during operation. The Figure should be read
in conjunction with Table 1.

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 3: Z-Range Battery Module dimentions
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. Figure 2 illustrates the stacking
methodology of the Z-Range using the brackets.
The battery voltages need to be within +- 0.5 V to be integrated. The batteries are shipped at
100%, and tend to settle around 53.5 V during transport. If an additional battery is added to the
system, it is recommended that the existing units be charged to 100% and allowed to settle (be
without loads or charging) to integrate the new battery.
Figure 3 shows the Z-Range dimentions

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.
It is recommended that the disconnect be 1.25 x Rated current.
Wiring methodology #1:
Connect all the batteries to a common busbar. Each battery can produce its maximum
recommended output current, with this methodology. This methodology allows each battery
unit to produce its maximum recommended output current. Connect the provided DC cables
to the top DC post of each unit, and the M8 lug to the common busbar. Figure 4 depicts the
connection methodology.

Communication
The communication cables start from the master unit’s Link A port to Link B on the second
unit. This A -> B loop continues, in sequence, up to the last unit. No termination plug is
necessary on the final Z-Range unit. Figure 6 shows the connection of the communcation
cables between the batteries.
Figure 6: Communication connections between the battery
modules
Figure 5: Illustrating daisy chain DC connections from top
to bottom
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. The interconnecting cables can be made from the
other batteries’ DC cables by cutting the lug side cable, and crimping the provide amphenol
connecter. The recommended length of this interconnecting cable is 150 mm.
8Z -RANGE INSTALLATION MANUAL
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. The battery has a baud rate of 500 kbps.
Table 2 below shows the pin outs of the inverters that the Z-Range battery is compatible with.
These are the only cables that are necessary to connect.

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.
Table 3: Assignment of Addresses to Z-Range Battery
Address Dip Switch Position Unit Stack
1 2 3 4 5 6
1 1 0 0 0 0 0 Master unit / individual unit
2 0 1 0 0 0 0 First secondary
3 1 1 0 0 0 0 Second secondary
4 0 0 1 0 0 0 Third secondary
5 1 0 1 0 0 0 Fourth secondary
6 1 1 1 0 0 0 Fifth secondary
… … … … … … … …
63 1 1 1 1 1 1 Sixty third secondary
Note that the 1 indicates that the dip switch needs to be in the “up” position, while the 0
indicates a “down” dip switch.

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.
1. Ensure the fuses to the battery are completely open or removed. The communication cable
to the GX device/inverter must also be removed.
2. Before switching on the battery ensure the wiring of the battery is done correctly, according
to this manual
a. Communication cable
b. Electric cables
3. Start by switching on the Master unit (using switch 3).
a. The battery will go through a boot up procedure where the SoC, Alarm and Run
lights flicker on
b. The Run light will flicker on for 1 second and off for 3 seconds if the start up procedure is
done correctly and the SoC lights are on
4. The next unit can be switched on if the previous unit’s Run light flashes as mentioned in
step 3b
a. The next unit’s Run light must flash at the same tempo as the master unit before any
additional unit can be switched on
b. The lights will not flicker simultaneously, but at the same tempo
5. Repeat step 4 for all the additional units
6. Connect the communication from the GX device to the CAN port on the master unit once
all the units in the stack have been switched on and the Run lights flash correctly
7. Close the fuses
The battery bank might indicate an Alarm event when the fuses are closed. If the bank does
not recover on its own, it is recommended to first energize the DC busbar with the inverter
before start by switching on the Master unit.
The battery bank might indicate an Alarm event, when the fuses are closed. Especially when
the inverter:Battery ratio is lower than 1:1. If the battery does not recover on its own, it is
recommend to energize the DC busbar with the inverter or PV (if present) before closing the
fuses.
