6.9 AFCI(Optional)
6.9.1 Arc-Fault Circuit Interrupter (AFCI)
In accordance with the National Electrical Code R, Article 690.11, the inverter has a
system for the recognition of electric arc detection and interruption. An electric arc
with a power of 300 W or greater must be interrupted by the AFCI within the time
specified by UL 1699B. A tripped AFCI can only be reset manually. You can deactivate
the automatic arc fault detection and interruption (AFCI) via a communication product
in "Installer" mode if you do not require the function. The 2011 edition of the National
Electrical Code R, Section 690.11 stipulates that newly installed PV systems attached to
a building must be fitted with a means of detecting and disconnecting serial electric
arcs (AFCI) on the PV side.
6.9.2 Danger information
Danger of fire from electric arc
Only test the AFCI for false tripping in the order described below.
Do not deactivate the AFCI permanently.
If an "Error 200" message is displayed, the buzzer alarms, an electric arc occurred in
the PV system. The AFCI has tripped and the inverter is in permanent shutdown.
The inverter has large electrical potential differences between its conductors. Arc
flashes can occur through air when high-voltage current flows. Do not work on the
product during operation.
When the inverter error 200, please follow the steps:
6.9.3 Operation step
6.9.3.1 Turn the DC & AC Switch to position "OFF".
6.9.3.2 Perform troubleshooting on the PV system:
Wait for the screen be off.
Check the PV strings' open circuit voltage is normal or not.
6.9.3.3 After the fault is rectified, restart the inverter:
Turn the DC & AC Switch to position "ON".

7 Debugging
1.Close the DC switch on the inverter.As long as the input DC voltage is greater
than 140V,the inverter display will show the following information:No mains
connection error,the inverter LED will turn red.
If other information is displayed,please refer to Chapter 13.If you encounter any
problems during the debugging process and cannot solve it,please contact customer
service.
2.Close the circuit breaker or switch between the inverter and the grid, the inverter
will start a countdown to the self-check,and after the self-check is normal,it will be
connected to the grid.
3.In normal operation,the leaves of the inverter indicator window will turn green.
4.Finish debugging.
