Z -RANGE INSTALLATION MANUAL
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.
