DC Connection
6.6.1 Checking before Connection
Check the following items before cable connections.
•
Check the open-circuit voltage of the PV array to ensure the open-circuit voltage is
less than the max. DC voltage of the module.
•
Mark the negative and positive polarity of the cable.
•
Check the PV modules for possible ground fault.
•
Open-circuit voltage of the PV array should not exceed the max. DC voltage
of the module. The module may be damaged if otherwise.
•
If a ground fault is detected, remove it before performing any DC connection.
Strictly follow all the instructions when connecting the cables.
Observe all the safety rules specified by the PV array manufacture.
Start DC connection only when all checks and measurements meet requirements.
