8.1.2.3 3 second flashing
The inverter is in self-limiting mode because it has reached the maximum permissible temperature.
In this situation, check that the fans are running, that the air inlets and vents are free from obstacles, and that there
are no sources of intense heat near the inverter. If the problem persists, contact Ingeteam Energy S.A.
8.1.2.4 Steady light
This LED indicates that an alarm has occurred in the inverter. Shown below are some of the alarms which can indicate
problems in the inverter which can be checked and/or resolved.
0400H, Manual stop. The unit has been stopped manually.
Check that the manual stop is not activated. If it is,
release it from the display.
0001H, Vin out of range.
0002H, Grid frequency out of range.
0004H, Grid voltage out of range.
Chances are that the problem is a power failure. It must be borne in mind that the alarms are additive, hence when
this fault occurs, the alarm shown will be 0006h, which is the sum of 0002H + 0004H.
When power returns, the inverter will restart. If not, check the connections to the grid.
If the grid has the appropriate grid quality parameters, check the grid connections.
If the problem persists, contact Ingeteam Energy S.A.
0020H, Insulation fault in DC circuit.
Possible causes are:
- There is an insulation fault on the circuit panels.
- The varistor-thermal fuse protection has tripped.
- The fault current or differential current protection has tripped.
An insulation fault can pose a hazard to personnel.
The repair of an insulation fault must be carried out by qualified personnel.
Procedure for determining which of these two conditions caused the insulation fault.
- Check that the insulation fault is not in the solar panel circuit by disconnecting the different circuits.
- If possible, connect the inverter to an alternative panel circuit which does not have this problem.
- If the fault persists, measure the voltage between each panel array branch and ground.
- If the voltage measured is constant and coincides approximately with open circuit current, there is a ground fault
in this branch. Each branch must be checked.
- If the fault persists after fixing the ground fault, check varistor-thermal fuse protection.
For the following check, take careful note of the following warning:
There are electrical capacitances in the unit which can maintain high voltages even
after having disconnected the inverter from the solar panels and the grid. Always wait
10 minutes after disconnection before opening the inverter.
