Troubleshooting
8.
This is a troubleshooting guide to help resolve problems that may arise with regard to
the Ingecon
It isexplained how to replace some components or make some adjustments too.
Any probelms arising with the Ingecon
qualified personal, observing the general safety conditions set out in this manual.
8.1
LED indications
Some LED indicate a particular problem in the PV installation:
green
ESC
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:
8.1.1.1 Flashing slowly
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.
8.1.1.2 Flashing quickly
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 1 minute.
8.1.1.3 LED remains on
The inverter is connected to the grid.
