8.3 Inverter alarms caused by protections
0100H,
AC circuit protections.
It appears when an AC protection has shotdown.
Monitorised elements are:

Which are Surge Arresters and contactor Protections.
In normal operation, every switch has to be closed except of contactor circuit. If there
is and alarm, signal circuit has to be checked to verify where the circuit is opened.
There may be several causes, as broken circuit cables, shotdown protection, fused
Surge Arrester, connector.

AC
(OPTIONAL)
If the equipment has AC surge arresters, check the status indicator. If it is green they
are correct; if it is red, replace it. Check it´s wires too.
0200H,
DC circuit protections.
It appears when an DC protection has shotdown.
Monitorised elements are:

DC
- RV
DC
(OPTIONAL)
If the equipment has DC surge arresters, check the status indicator. If it is green they
are correct; if it is red, replace it. Check it´s wires too.
8.4 Disconnection from the Grid
If the unit has been disconnected from the Grid as a result of the triggering of one of
the surge arresters or protection fuses, the corresponding «Motivo de Paro» (reason for
shutdown) and «Alarma» (alarm) will be displayed (see the monitoring section).
Proceed as follows:
Disconnect the equipment from the power grid and PV array.
Wait at least 10 minutes for the internal capacitance to discharge
Open the inverter and check the status of the various MT breakers mentioned in the
previous section «Prior to start up»and that the AC varistors are closed (over-voltage
arresters)
Check the AC surge arresters and the AC fuses.
Replace any faulty elements if necessary.
Close the inverter, reconnect the equipment to the power grid and PV array.
Check that the inverter correctly connects to the Grid.
