Significance of the inverter LED

Your solar kit doesn't want to work or is experiencing operating difficulties, here's a tutorial to help you understand the warning lights and make a pre-diagnosis.

This tutorial is applicable for:

Difficulté : Easy
Temps nécessaire : 5 minutes
Nombre d’étapes : 5
Mise à jour : February 2025

Tutorial steps:

Step 1: Locating the inverter

  • The inverter is equipped with operating LEDs to indicate its status.
  • This is located at the end of the 230V cable and must be installed under one of the solar panels.
  • Unscrew the two screws on the inverter support to remove the inverter.
  • Be careful not to drop the inverter.
  • Depending on the amount of sunshine outside, the inverter can be very hot.
  • Handle the inverter with care, as it is connected to 230V.
  • The inverter has only one LED. It can be blue or red. It can be fixed or flashing.

Step 2: Meaning of indicator light

Indicator off

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

 

Solution: Make sure the solar panels are all connected to each other and that each plug is fully inserted.

Steady 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 that there is power in the socket.

Flashing red light

  • The inverter is powered by solar panels, but is neither connected to WiFi nor to a 230V socket.

 

Solution: Make sure that the inverter is plugged into a 230V socket and that there is power in the socket. Once this problem has been solved, you’ll be able to connect to wifi.

 

 

Steady blue light

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

Flashing blue light

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

 

Solution: MPPT (Maximum Power Point Tracking) continuously adjusts the voltage and current produced by the solar panels to match the electrical grid.the voltage and current produced by the solar panels to adapt them to the electrical grid.

If the blue LED does not stabilize, this means that the solar panels are not receiving stable sunlight, or that the power grid is not stable. Please orient your solar panels all in the same direction, and have your electricity supplier check the stability of your grid.

 

 

Steady blue light + flashes red every 3 seconds

  • The inverter is powered by the solar panels at its best MPPT point and is connected to a 230V socket. But it is not connected to Wifi.
  • The solar kit generates power in this configuration.

 

Solution: Simply connect your solar kit via wifi to your internet box, guided by the avidsenHome application.
