The two 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 as 3.4.5 after using
the function.
Press the key until the LCD displays "Wi-Fi Reset", then long press (2S) until the LCD displays "Wi-Fi Resetting...". Stop pressing and
wait for the screen showing "Wi-Fi Reset OK" or "Wi-Fi Reset Failed".
Press the key until the LCD displays "Wi-Fi Reload", then long press (2S) until the LCD displays "Wi-Fi Reloading...". Stop pressing
and wait for the screen showing "Wi-Fi Reload OK" or "Wi-Fi Reload Failed".
5 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 the solutions for associated faults.
Display
1.Disconnect DC switch, take off DC connector, Check the impedance between PV (+)
& PV (-) to earth.
2.If impedance is less than 100 kΩ, please check the insulation of PV string wiring to

the earth.
3.If impedance is larger than 100 kΩ, please contact local service office.
4.Take off AC connector, measure the impedance between neutral and PE. If it is
larger than 10 kΩ, please check AC wiring.
1.Disconnect DC switch, check the insulation of PV string wiring to earth.
2.Reconnect the DC switch again.
Ground I Fail
3.If the problem still exits, please call the local service office.
1.Disconnect the DC switch, taking off AC connector, measuring the voltage between
line and neutral in connector, make sure if it conforms to the grid-connected

specification of inverter.
2.If it does not, please check grid wiring.
3.If it does, please connect AC connector, reconnect DC switch, inverter will connect
grid automatically. If the problem still exits, please call the local service office.
1.The PV Inverter will automatically restart if the Fac returns to normal.

1.Disconnect the DC switch, taking off AC connector, measure the voltage between
line and neutral n connector, make sure if it conforms to the grid-connected
specification of inverter.
2.If it does not, please check if the distribution switch is connected and the grid is

normal.
3.If it does, reconnect AC connector and DC connector; If the problem still exits,
please call the local service office.

Troubleshooting
Display
1.Disconnect the DC switch, take off DC connector, check PV string voltage, make sure if
it exceeds the input voltage in inverter specification.
PV Over Voltage
2.If it does, please reconfigurate PV panel string.
3.If the problem still exits, please call the local service office.
System
1.Please check if installation position conforms to the specification.

2.Try to lower the surrounding temperature.
Over Temperature
3.Move the inverter to vents or alter the installation position.
4.If the problem still exits, please call the local service office.
Relay-Check Fail
1.Disconnect the DC connector.

3.If the problem still exits, please call the local service office.
EEPROM R/W Fail
SPI Fail
1.Disconnect the DC connector.

2.Reconnect the DC connector.
DC Bus High
failure
3.If the problem still exits, please call the local service office.
GFCI Fail
1.Disconnect the DC switch, take off DC connector, measure the voltage of PV string.
2.Plug in DC connector, and reconnect DC switch.
3.If the voltage is less than 70V, please check the PV string configuration.
No display
4.If the voltage is higher than 125V and still no display, please contact local service
office.
Note: When sunlight is insufficient, the PV Inverter may continuously start up and shut down automatically due to insufficient
power generated by the PV panels, which would not lead to inverter damage. If the problem still exits, please call the local
service office.
