This function can be enabled to detect whether arc occurs in the DC circuit of the inverter.
• AFCI self-test
This function is intended to detect whether the AFCI function of the inverter is normal.
• Clear AFCI Alarm
When the inverter detects the AFCI alarm, it stops working. Clear the AFCI alarm so that
the inverter can restart the detection.
Optimizer Functions
• Module-level MPPT
Increase the power generation of the PV system by continuously tracking the maximum
power point of the PV module.
• Module-level shutdown
Quickly reduce module voltage.
• Module-level monitoring
The optimizer can monitor the performance of modules.
• Module-level IV curve diagnosis
The optimizer can scan the module IV curve and judge whether a module fault occurs.
And in this case the inverter cannot perform string-level IV curve scan.
The Module-level IV curve diagnosis function can only be used on iSolarCloud Web. At
most six modules can be selected in one round of Module-level IV curve diagnosis.
