MULTI CLUSTER CONNECTION WITH HIGH VOLTAGE HUB
Installation of a High Voltage Multi-Cluster System.
1. Install clusters with the same number of modules. Each module of each cluster must have the same voltage. Each cluster must
have the same total voltage.
2. Set the DIP switches of each HV Box with the addresses starting from ID 01 and continue in progressive sequence up to the last
HV Box.
3. The last HV Box must be connected to the HV HUB device, placed above the last tower.
4. Connect all the communication cables between the various HV BOXES using the CAN PORT 1A and 2A and proceed as shown in
the diagram below.
5. Connect the last HV BOX with the HV HUB device by connecting the CAN PORT 1A or 2A of the HV BOX with the CAN INPUT
PORT located on the HV HUB.
6. Connect the CAN BMS PORT of the HV HUB device to the CAN PORT of the inverter following the inverter manufacturer PIN.
7. Power the HV HUB device with two high voltage cables from the parallel connection between the various clusters. The HV
HUB device is powered with a minimum of 100V (max 1000V).
Attention: Do not turn on the HV HUB device (power key kept off)
8. After checking all high voltage power connections and making sure polarity is correct, visually check all connections by double-
checking the manual.
9. Press the HV HUB power button.
10. Activate the first switch of the HV BOX ID01 and wait for the total start-up of the first cluster. Only when the first cluster is
fully operational is it possible to proceed with the start-up procedure of the second cluster.
11. Wait for the complete start-up and then proceed with the same methodology for each cluster.
12. At this point, the start-up procedure is completed and the HV HUB device will initiate the control procedure of each single
cluster by activating the HV HUB contactors one by one to prevent voltage spikes.
13. The start-up procedure foresees the deferred switching on of the various clusters with a delay of at least 5 seconds from each
other.
ATTENTION:
In a multi cluster system, only the HV BOX with address ID01 will close the circuit in order to power the HV HUB from the common
bus bar. All the remaining HV BOXES will receive the input of closing the HV BOX contactor only when the entire cluster procedure
is completed by the HV HUB.
HUB HV logic includes a voltage control algorithm that controls the consistency of each cluster before allowing the closing the HV
BOX contactors.
The PC software will indicate any discrepancies that prevent installation.
