Installation manual
8. Troubleshooting
This is a guide to help resolve any problems which may arise when installing and operating the Ingecon
You will also find information on how to perform simple component replacement tasks or adjust equipment settings.
CAUTION
Any problems occurring in the Ingecon
observing the general safety conditions set out in this manual.
8.1. LED indications
Some LED indicate a particular problem in the PV installation.
8.1.1. Green LED
This LED should be on when the start-up process and operation is normal, whilst the other LEDs should be off. There
are three ON modes.
Flashing every 1 second
This flashing indicates that the PV array is providing sufficient voltage to the inverter for delivering energy, and it is
preparing to start-up. In this situation, the inverter checks the grid parameters in order to deliver current to the grid
at the exact grid voltage and frequency. This process lasts about 5 minutes.
Flashing every 3 seconds
Flashing every 3 seconds indicates on-hold status due to low radiation. This alarm is triggered when the PV array is not
receiving sufficient radiation to provide the inverter with the minimum voltage required to deliver energy to the grid.
This situation is typical between sunset and sunrise or at a time when rain, clouds or other atmospheric phenomena
cast a dark shadow over the PV array area.
If this situation occurs on a day which is not particularly dark, check that the panels are clean and correctly connected.
LED remains on
The inverter is connected to the grid.
8.1.2. Orange LED
This LED indicates that an inverter alarm has been triggered.
Flashing every 0.5 seconds
The external fan is not functioning correctly.
Check that no foreign bodies have got into the fan and are preventing it from rotating. Check that the air supply to
the fan is sufficient.
Flashing every 1 second
The internal fun is not functioning correctly.

Flashing every 3 seconds
Inverter auto-limitation, due to the fact that it has reached the maximum allowable temperature.
In this situation, check that the fans are operating, that the air inlets and outlets are free from obstacles and that there
are no intense heat sources close to the inverter. If the error persists, contact Ingeteam Inc
LED remains on
This LED indicates that an alarm has been triggered in the inverter. Listed below are some of the alarms which could
indicate a problem in the inverter and which can be checked and/or corrected:
