Installation manual Ingeteam Power Technology, S.A.
Code Description
4000H
Overvoltages in the panel inputs.
This alarms indicates an out-of-range voltage at the PV input.
A voltage greater than 900 VDC will cause the equipment to shut down. Voltages greater than 1000 VDC
will damage the equipment.
8000H
Very low voltage on the input from the panels.
This alarms indicates an out-of-range voltage at the PV input.
The equipment will be on standby until the panel voltage reaches the necessary value for a connection.
0020H
Temperature alarm in the power electronics.
The temperature of the unit is too high and has stopped feeding current to the grid. When the tempera-
ture drops, the unit will reconnect.
9.4. Action protocol for responding to incidents
If the unit should stop interacting with the network due to the emergence of issues relating to the installation and/or
the inverter, the fastest way to resolve the issue is as follows:
1. Check on the display the alarm and the reason for shutdown reported by the unit. Search in this guide’s index
to see if the alarm or reason for shutdown is indicated. If it is covered, proceed to step 2; if on the contrary it is
not covered, take note of the unit’s serial number and contact Ingeteam’s telephonic technical service, the number
of which is listed on a sticker on the document pocket behind the door.
2. Disconnect the unit from the supply. This will disconnect both the AC and auxiliary connections by opening
the thermomagnetic circuit breaker and the DC section by opening the PV array breaker. After AC and DC power
is switched off, wait 10 minutes before opening the unit, to ensure that their internal capacitance is discharged.
IMPORTANT
Only in the event of an insulation fault triggered by alarm 0400H will the AC power be switched off
and the DC power be left.
3. Open the unit and find the section in this guide that deals with the alarm or reason for shutdown recorded
in the first step.
4. Use a category III, 1000 V
DC
multimeter which can measure continuity, resistance and capacitance, and
proceed to carry out the checks listed here.
5. If unable to solve the problem using this guide, take note of the unit’s serial number and contact technical
service.
Below is a list of possible reasons for shutdown, their associated alarms and troubleshooting guidelines. If more than
one alarm takes place, the alarm on the display will be the sum of all active alarms.
E.g.:
Code Alarm
0001H Grid frequency
0002H Voltage
0003H Grid fre voltage
9.4.1. Voltage and/or frequency out of range
One reason for shutdown associated with out-of-range voltage and/or frequency features the alarm codes listed below:
Code Alarm Reason for shutdown Description
0001H Grid frequency Grid frequency Grid frequency out of range
0002H Voltage Voltage Voltage out of range
0003H Grid fre voltage Grid fre voltage Grid frequency out of range + Voltage out of
range
In the event of a “0001H” and/or “0002H” alarm, you must check the status of the Q4 breaker protection and all the
