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;
Step2: Perform troubleshooting on the system, Check all PV strings for the correct open-circuit
voltage;
Step3: After the fault is rectified, restart the inverter. Turn on BDC Box’s battery input switch, turn
on the the inverter’s AC output breaker, turn the inverter’s PV input DC Switch to position “ON”,
Waiting for the system to work properly;
