4. Troubleshooting

This is a guide to help resolve any problems which may arise when installing and operating the Ingecon
TL.
It also explains how to perform simple component replacement operations and how to adjust the equipment settings.
Any problems detected in the Ingecon
observing the general safety conditions set out in this manual.

4.1. LED indications

Some of the LEDs indicate a particular problem in the PV system:

4.1.1. Green LED

This LED should be on when the start-up process and operation is normal, whilst the other LEDs should all be off.
There are three ON modes:
Flashing every 1s
This flashing indicates that the PV array is providing adequate voltage to the inverter in order to then deliver energy
to the Grid, and the inverter is preparing to start-up. In this status, the inverter checks the grid parameters in order to
deliver current to the grid at the exact grid voltage and frequency. This process takes about 1 minute.
Flashing every 3s
This is the on-hold status due to low irradiance. The LED flashes every 3 seconds. This alarm is triggered when the
PV array is not receiving sufficient irradiance to provide the inverter with the minimum voltage required to deliver
energy to the grid. This is a typical situation between sunset and sunrise, or when rain, clouds or other atmospheric
phenomena are casting a dark shadow over the PV array area.
Should this situation occur on a day that is not particularly dark, check that the panels are clean and connected cor-
rectly.
LED remain on
Inverter connected to the grid.

4.1.2. Orange LED

This LED indicates that an inverter alarm has been triggered.
Flashing every 0,5s
The external fan is not operating correctly.
Check for the presence of foreign bodies in the fan, preventing it from rotating. Check for sufficient air flow.
Flashing every 1s
The internal fan is not operating correctly.
Contact your installer.
Flashing every 3s
The inverter is limiting the power delivered to the Power grid due to the fact that it is at the maximum permitted
operating temperature.
If the ambient temperature is below the maximum temperature, then check that the fans are operating correctly, 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 your installer.
LED remains on
This LED indicates that an alarm has been triggered in the inverter. Listed below are some of the alarms that could
indicate a problem in the inverter and which can be checked and / or corrected:
0400H Manual Stop. The inverter has been shutdown manually. Check that the Manual Stop is not activated and,
if it is, deactivate it on the display.
0001H Vin out of range.
0002H Power grid frequency out of range.
