6.5 Grounding the inverter
The inverter must be connected to the AC grounding conductor of the power
distribution grid via the ground terminal (PE) .
Because of the transformerless design, the DC positive pole and DC negative
pole of PV arrays are not permitted to be grounded. WARNING
According to the relevant provisions of IEC 61643-32 “Connecting to
photovoltaic devices surge protectors – selection and use of guidelines”,
whether for household or commercial photovoltaic power plants, it is necessary
to ensure the implementation of lightning protection measures for photovoltaic
systems.
WARNING
The lightning protection measures for photovoltaic systems shall be carried out in accordance with the corresponding national standards and IEC standards. Otherwise, photovoltaic devices such as components, inverters and power distribution facilities may be damaged by lightning. In this case, the company does not carry out warranty and assumes any responsibility.

1It is generally recommended to install lightning protection devices (such as
lightning rods / lightning protection belts and down conductors) to prevent
lightning from hitting the PV array. 2Lightning protection devices and down-
conductors and related equipment in photovoltaic systems (including
photovoltaic panels, inverters, cables, power distribution equipment) should
maintain a safe separation distance S. Suggested value of S: According to the
general 5 storey height (about 15m) building roof, S takes 2.5m enough, this
distance can be simplified according to the inverse relationship of the floor
height.
23
A. When the safety distance S is satisfied: The position of the figure should
be equipped with a lightning protection module. In general, it is recommended
to install Type II in position and Type I in position . B. When the safety and
safety distance S is not met: In addition to position 3, Type I lightning
protection module should be installed in Figure . 3The lightning down
conductor and the equipment ground wire eventually sink at a total ground
point, but the two cannot share the wire. That is, the equipment grounding
wire should be pulled separately, and the wire diameter requirement >6mm² when
the safety interval distance S is satisfied. 4About the above lightning
protection lightning receptor system related design reference GB/T

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”.
Fig 6.18 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”.
Fig 6.19 28
6.8.4 Earth Fault Alarm The inverter complies with AS/NZS 5033.When the Earth
fault occurs, the Red LED will light up.The buzzer in the inverter will keep
ringing unless the fault condition is cleared(This function is only avilable
for Australia and New Zealand). ·If there is PV isolation low alarm, there
might be some fault for the inverter case ground protection,please do not
touch the inverter case.

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.
Working Mode 8
8.1 Normal mode
In this mode, the inverter works normally. Ø When the DC voltage is greater
than 250V, the energy is sufficient, and the grid
voltage frequency meets the grid-connected requirements, the inverter will
convert the energy of the solar panels into AC power and export to the grid,
and the green LED will light up. Ø When the DC voltage is lower than 180V, the
inverter will automatically disconnect from the grid and exit the normal
operation mode. When the input voltage reaches the requirement again and the
grid voltage and frequency return to normal, the inverter will automatically
connect to the grid.
8.2 Failure mode
The inverter controls the chip monitors and adjusts the state of the system in
real time. When the inverter monitors any unexpected conditions,such as system
failure and inverter failure,the display will show the fault information.In
the failure mode,the inverter will indicate The leaves of the window will turn
red and the inverter output will be disconnected from the grid.
8.3 Shutdown mode
When the sunlight is weak or there is no sunlight,the inverter will
automatically stop running.When in shutdown mode,the inverter basically does
not consume energy from the grid or solar panels,and at the same time,the
inverter’s display screen and LED lights will be turned off.
