9.3. Inverter alarms due to protections
Code Description
0100H
This alarm goes off when an AC protection element is triggered.
The items monitored are:

Which are the protections for the filters and AC intakes and DC intakes and contactor.
In normal operation, all contacts should be closed, except for the contactor circuit. Check the signalling circuit to
see where it is broken. The causes may be broken cables in the circuit, a triggered protection, fused arresters or a
connector out of its base.

In normal operation all contacts must be closed. Check the signalling circuit to see where it is broken. The causes
may be broken cables in the circuit, fused arresters or a connector out of its base.
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 temperature 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.
