6.4 PV Connection
Please ensure the follows before connecting PV strings to the inverter:
•
Make sure the open voltage of the PV strings will not exceed the max. DC input voltage (580
VDC). Violating this condition will void the warranty.
•
Make sure the polarity of the PV connectors is correct.
•
Make sure the PV-switch, breakers of battery, AC-BACKUP and AC-Grid are all in their off-
states
•
Make sure the PV resistance to ground is higher than 200 kΩ.
The inverter includes Staubli MC4 PV connectors.
Please follow the picture below to assemble the PV connectors.
PV conductor cross section requirements: 4-6mm²
