3.6.3 HV Box and Battery Module Power Connection

Step 1: Keep the power box main breaker OFF (located on the side).

Step 2: Connect the positive terminal of the HV Box to the Positive terminal of the 1

Battery Module.

Step 3: Proceed with the serial connection between all the modules.

Step 4: Connect the negative output from the last module to the negative input of the HV Box.

Step 5: Connect the Inverter Input Channels to the inverter (follow the inverter manual).

Step 6: Turn on the HV Box breaker and wait for the start-up automatic procedure.

Step 7: The HV Box will end the startup procedure within 60 seconds by closing the input circuit. The RED and the GREEN

light will turn on, confirming the working status of the HV Box.

Step 8: Each module will turn on automatically and the side button will blink for 3 seconds, then a fixed GREEN light will

confirm the run status of each module.

If one or more modules do not turn on automatically, it is necessary to check all the COM connections and restart the START UP

procedure.

ATTENTION: In the event of missed communication between the inverter and HV BOX for more than 60 seconds, the HV BOX

will enable the safety procedure by opening the POWER CONTACTOR.

During the commissioning phase the installer must ensure that the communication between the HVBOX and the Inverter is

correctly connected.

Do not leave the system powered in absence of communication between the HV BOX and the Inverter, a prolonged standby of

the cluster could cause an imbalance caused by the natural self discharge.

Information: Arrange the cables according to the specific installation requirements, always paying

attention to minimize the length of the cables to avoid voltage drops.

Note: if the system is composed of more than 6 modules, it is required to arrange them as per the image.

Alternate arrangements are strictly prohibited.
