INVERTER ALARMS
Code
Alarm
Description
A01
External Shutdown Activated
Inverter switched off by means of a remote tripping command. Remote trip-
ping enabled. Check whether the remote tripping command is enabled.
A03
GFCI Fault
Fault in the system measuring current to earth (GFCI sensor). Contact the
Support Service.
A07
AC Connection System Fault
Fault in the AC output connection system. If the contactors are not working
properly, the inverter will not connect to the mains network for safety reasons.
If the alarm persists, contact the Support Service.
A14
Digital System Fault
Internal error. If the fault occurs frequently, contact the Support Service.
A70
Maintenance Mode
The inverter is in maintenance mode. Contact the Support Service.
A72
Inverter Fault
The internal check has detected a hardware malfunction. If the fault persists or
occurs frequently, contact the Support Service.
A78
Autotest Failed
Fault in the interface protection system. Contact the Support Service.
A79
DC Current Injection
The direct current injected into the network has exceeded the permitted limit. If
the fault occurs frequently, contact the Support Service.
8.4. System
alarms
SYSTEM ALARMS
Code
Alarm
Description
A02
GFCI Alarm
Dangerous change in differential current or high discharge to earth. Integrated
monitoring of the differential current is important for the protection of individuals. If
the alarm persists for no reason, make sure the parasitic capacity of the photovol-
taic system is under 100 nF/kWp.
A04
Insulation Alarm
The insulation resistance (Riso) of the photovoltaic system to earth is insufficient.
Make sure there is no discharge to earth from the photovoltaic system, and that the
parasitic capacity of the photovoltaic system to earth is under 100 nF/kWp.
A58
IN1 External Alarm
Alarm indication associated with digital input IN1.
A59
IN2 External Alarm
Alarm indication associated with digital input IN2.
A60
IN3 External Alarm
Alarm indication associated with digital input IN3.
A61
IN4 External Alarm
Alarm indication associated with digital input IN4.
A68
High Temperature Alarm
Inverter temperature over the maximum operating limit. Make sure the inverter
is located in a cool, well-ventilated room.
A73
DC Over-voltage
Disconnect the photovoltaic field to avoid damaging the appliance. Check the
system configuration and make sure the maximum photovoltaic field voltage
falls within the acceptable range before reconnecting the inverter.
A76
Low Temperature Alarm
Ambient temperature below the minimum operating limit. Make sure the inverter
is located in a sheltered environment with a suitable operating temperature range.
A80
DC Over-current
Measured DC current above the operating range. Check the system configuration
and make sure the maximum photovoltaic field current falls within the acceptable
range before reconnecting the inverter. Contact the Support Centre if necessary.
