maximum system short circuit current (Recommended cross section area of cable is 4mm2 for a
single module and rated current of a connector is larger than 10A), otherwise the cable and
connector will be overheated under large current. Please note that the upper limit temperature of
cable is ≥85℃, and the connector is ≥105℃.
The junction box has a breather port. The breather port must be mounted facing down and can
not be exposed to rain. Therefore, the junction box must be on the higher side of the module
when it is mounted.
Commission and Maintenance
First, check all wiring connections to make sure it is not open-circuit or is not connection well.
Check the open-circuit voltage of each module:
Fully cover the modules with an opaque material.
Disconnect the wiring at both terminals of the modules.
Remove the opaque material from the module to be checked and measure the open-circuit
voltage at its terminals.
If the measured voltage is only half of the rated, this indicates a defective bypass diode. Refer to
‘Testing and replacing bypass diodes’.
