4.4 Wi-Fi Reset & Wi-Fi Reload

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

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.

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.

3.Move the inverter to vents or alter the installation position.

4.If the problem still exits, please call the local service office.

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.
