6.8 Arc fault current interrupt (AFCI) function
The Canadian Solar Three Phase inverter series can be supplied with an integrated AFCI module
which can detect and interrupt a serial arc in the DC circuit(s). If an arc fault occurs, the AFCI
module will detect the arc and interrupt the circuit. The fault can only be cleared manually.
This setting is for export power control. Please don’t change settings in this item.

6.7.9.4 10mins Voltage Set
This function is disabled and
not used for the US.
6.7.9.6 Initial Settings
In initial settings it will reset each work mode back to default.
This function is applicable by maintenance personnel only, wrong operation
will prevent the inverter from reaching maximum power.
6.7.9.5 Voltage PCC Set
Set the voltage at the PCC point.
This setting is required by RULE 21 requirements.
PCC: Point of Common Coupling, the point where a Local EPS is connected to an Area EPS.
This function is applicable by maintenance personnel only, wrong operation
will prevent the inverter from reaching maximum power.
An arc fault indicates an irregularity in the DC portion of the PV system. This could be a faulty
PV panel, a bad DC connector or even a short circuit in the DC cabling. Check the entire DC
portion of the system to ensure there is no evidence of an arc fault.
After confirming the DC portion of the array or effecting repairs of the array, press <ESC> for
three (3) seconds, after which the inverter will restart. If the fault happens again, turn off and
restart the inverter. If the fault still happens, contact Canadian Solar Support Service.
