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 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.
6.8.2
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:
6.8.3
Operation step
6.8.3.1 Turn the DC & AC Switch to position "OFF".
6.8.3.2 Perform troubleshooting on the PV system:
Wait for the screen be off.
Check the PV strings' open circuit voltage is normal or not.
6.8.3.3 After the fault is rectified, restart the inverter:
Turn the DC & AC Switch to position "ON".

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
8.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
