6.8 AFCI(Optional)
6.8.1 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 300Worgreatermustbe interrupted bytheAFCI within
the time specified by UL 1 699B. 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" modeifyoudonotrequirethefunc-
tion.The2011 editionofthe 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.
Danger of fire from electric arc
Only test theAFCI for false tripping in theorder 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 per manent 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:
6.8.3 Operation step
6.8.3.1 Turn the DC & AC Switch to position "OFF
11
.
Wait for the screen be off.
6.8.3.2 Perform troubleshooting on the PV system: Check-
the PV strings' open circuit voltage is normal or not.
6.8.3.3 After the fault is rectified, restart the inverter:
Turn the DC & AC Switch to position “ ON “.
