5.7.3 Installing PV Connector
step 1 Ensure that the DC switch is in "OFF" position. Otherwise, manually turn it to "OFF".
step 2
Check the cable connection of the PV string for polarity correctness and ensure that the open circuit
voltage in any case does not exceed the inverter input limit of 1,100 V.
NOTICE
The multimeter must have a DC voltage range of at least 1100 V. If the voltage is a negative
value, the DC input polarity is incorrect. Please correct the DC input polarity. If the voltage
is greater than 1100 V, too many PV modules are configured to the same string. Please
remove some PV modules.
step 3
Connect the PV connectors to corresponding terminals until there is an audible click.
