5.4. Connecting of the PV Modules
For connecting DC input of one single Inverter, connected strings must consist of modules of the same type.
Do not share the DC input connection with other Inverter. The number, orientation, and tilt of panels may differ
for different application.
The input terminals on the Inverter are Multicontact MC4
DC connectors. Appropriate cable couplers from the
same manufacturer should be used for DC input connection.
The following table lists those connector pairs:
Advice before connecting of PV module
To obtain optimal result from PV inverter, please consider the following guidelines before connecting the PV
modules to the device:
1. Firstly make sure the maximum open circuit voltage (Voc) of each PV string does not exceed the related
specification as below table listed in all condition.
2. Check short-circuited current of the PV string. The total short-circuits current ( I
sc
) of the PV string should
not exceed the Inverter
’s maximum DC current.
3. Always connect PV modules positive (+) terminal to PV inverter DC positive (+) terminal; negative (-)
terminal to PV inverter DC negative (-) terminal.
4. Each group of terminals of the DC 'inverter converts a DC current of maximum 24A.
