Step 1: Location of the inverter

  • The inverter has operating lights indicating its operating state.
  • The latter is located at the end of the 230V cable and must be installed under one of the solar panels
  • Unscrew both screws from the inverter support to extract the inverter.
  • Be careful not to drop the inverter.
  • Depending on the outside sunshine, the inverter can be very hot.
  • Handle the inverter carefully, the latter is connected to the 230V.
  • The inverter has only one light. It can be blue or red color. It can be fixed or flashing.

Step 2: Meaning of the light

Seeant extinguished

  • The inverter is not powered by solar panels.
  • It is normal for this light to be extinguished at night, at dawn or dusk

Solution: Make sure all solar panels are connected to each other and that each plug is well pressed.

Fixed red light

  • The inverter is powered by solar panels and is connected to WIFI but is not connected to a 230V socket

Solution: Make sure the inverter is plugged into a 230V socket and there is a lot of current in the socket.

Flashing red light

  • The inverter is powered by solar panels but is neither connected to Wi-Fi nor connected to a 230V socket.

Solution: Make sure the inverter is plugged into a 230V socket and there is a lot of current in the socket. Connection to wifi can be done once this problem is solved.

Fixed blue light

  • This is the normal operation of the inverter. The inverter is powered by solar panels at its best MPPT point, is connected to WIFI and is connected to a 230V socket.
  • The solar kit produces current in this configuration.

Blue light flashing

  • The inverter is powered by solar panels, is connected to WIFI and is connected to a 230V socket. Nevertheless, he is looking for his best MPPT point.
  • The solar kit produces current in this configuration, but it produces less than normal.

Solution: The Maximum Power Point Tracking (MPPT) adjusts en permanence the voltage and intensity produced by the solar panels in order to adapt them to the electrical network.

If the blue light does not stabilize, it means that sunlight is not stable or that the power grid is not stable. Please orient your solar panels all in the same direction as well as control the stability of your power grid by your supplier.

Fixed blue light + flashes in red every 3 seconds

  • The inverter is powered by solar panels has its best MPPT point and is connected to a 230V socket. But it is not related to Wifi.
  • The solar kit produces current in this configuration.
