6.10 Electric arc hazards
6.10.1 Arc-Fault Circuit Interrupter(AFCI)
In accordance with the National Electrical Code R, Article 690.11, the inverter has
asystem 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.
6.10.2 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.
The inverter has double MPPTs, it is recommended for each MPPT to work independently,
do not use parallel wiring at DC side (Parallel wiring can make 2 MPPTs become 1 MPPT,
this can improve the efficiency in some cases). If the MPPTs are parallel wired at inverter it
may cause the AFCI trigger mistakenly.
If an "Error 200" message is displayed, the red LED is permanently lit and 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.
6.10.3 Operation step
When the inverter error 200, please follow the steps:
Step1: Cut off all power supply connection of the inverter. Turn off the BDC Box's battery
input switch, turn off the inverter's AC output breaker, Turn the inverter's PV input DC
Switch to position “OFF”, wait for the display to go out;
