5.4 Wi-Fi Reset & Wi-Fi Reload
These functions are only available for Wi-Fi model inverters.
Wi-Fi reload function is used to change the Wi-Fi configuration to default value. Please configure
the Wi-Fi again after using the function.
Short press the button until the LCD displays "Wi-Fi Reset", then long press the button until the
LCD displays "Wi-Fi Resetting�". Stop pressing and wait for the screen to display "Wi-Fi Reset OK"
or "Wi-Fi Reset Failed".
6 Troubleshooting
In most situations, the inverter requires very little maintenance. However, if the inverter is not
working properly, please try the following troubleshooting solutions:
• When a problem occurs, the red (fault) LED indicator on the front panel will light up and the
LCD screen will display the type of fault. The following table lists error messages and solutions
for associated faults.
1. Check the impedance between ground and PV (+) & PV (-) . The impedance
value must be greater than 100kΩ. Make sure the inverter is earthed.
2. Contact local service office for help if the problem still persist.
1. Not connect to the grid.
2. Check if the power grid is connected to cable.
3. Check the availability of power grid.
1. Check if the PV open circuit voltage is higher or too close to the maximum
input voltage or not.
2. If the problem still persist when PV voltage is less than the maximum input
voltage, contact local service office for help.
1. The internal temperature is higher than normal value specified.
2. Reduce ambient temperature.
3. Move the inverter to a cool place.
4. If the problem still exists, contact local service office for help.
1. The ground current is too high.
2. Unplug the inputs from the PV generator and check the peripheral AC
system.
3. When the problem is cleared, reconnect the PV panel and check the Inverter
status.
4. Contact local service office for help if the problem still persist.
1. The PV Inverter will automatically restart within 5 minutes if the grid returns
to normal.
2. Make sure grid voltage conforms with the specification.
3. Make sure neutral (N) wire and PE wire are connected well.
4. Contact local service office for help if the problem still persist.
1. Grid is not connected.
2. Check grid connection cables.
3. Check availability of grid.

5.5 Precaution For Initial Startup
1. Make sure the AC circuit is connected and AC breaker is turned off.
2. Make sure the DC cable between inverter and PV string is connected, and the PV voltage is
normal.
3. Turn on the DC switch, and set safety country according to the local regulation.
4. Turn on the AC breaker. Check the inverter work normal.
5.6 Special Adjustable Setpoints
The inverter has a field where the user could set functions, such as trip points, trip times, recon-
nect time,active and inactive of QU curve and PU curve. It is adjustable through special software,
if you want to use it, please contact with after sales.
To achieve manuals for using the software, you can download them from official website or
contact with after-sales.
Short press the button until the LCD displays "Wi-Fi Reload", then long press the button until the
LCD displays "Wi-Fi Reloading�". Stop pressing and wait for the screen to display "Wi-Fi Reload
OK" or "Wi-Fi Reload Failed".
