8. TROUBLESHOOTING AND DIAGNOSTICS
The display indicates the system status, making it possible to instantly diagnose faults, malfunctions and break-
downs of the inverter or the photovoltaic system.
The following events are indicated:
•
Warnings
: Non-serious fault which will not necessarily cause the inverter to stop running. The warning disappears
from view as soon as normal conditions are restored.
•
Alarms
: Potential breakdowns of the inverter or system which cause the inverter to stop running. The indication is
removed as soon as the causes of the malfunction are diminished, except in the case of serious problems which
require the intervention of qualified personnel before normal operation can be restored.
Alarms and warnings are divided into two categories:
•
System Alarms/Warnings
: these affect the parts outside the inverter, such as the mains power network, the pho-
tovoltaic field and the ambient temperature. Corrective actions can, in general, be performed by the user (system
installer or operator).
•
Inverter Alarms/Warnings
: indications regarding the inverter itself. Corrective actions are, in general, performed
by the Support Service.
When running, the current inverter status appears on the display to inform the user as to the procedure in progress.
The standard statuses, however, are only outlined within the menu
HISTORY
.
The following tables summarise the indications which may appear on the display.
8.1. Inverter
warning
INVERTER WARNING
Code
Warning
Description
W65
Derating
The inverter is reducing the power supplied to the mains network due to voltage/
frequency outside the range, or due to settings made via remote control commands.
W69
AC Voltage Out Of Tolerance
AC mains network voltage outside the tolerance range, the inverter waits for the
parameter to return to a value within the limits set. If the warning persists and the
mains network voltage is within the tolerance range, contact the Support Service.
W70
AC Frequency Out Of Tollerance
AC mains network frequency outside the tolerance range, the inverter waits for the
parameter to return to a value within the limits set. If the warning persists and the
mains network frequency is within the tolerance range, contact the Support Service.
W74
Clock Battery Discharged
Clock battery discharged or not working. Replace the battery.
8.2. System
warning
SYSTEM WARNING
Code
Warning
Description
W01
Over-temperature Derating
Limited power supplied to avoid appliance overheating. Make sure the inverter
is located in a cool, well-ventilated room.
W02
Under-temperature Derating
Limited power supplied due to low temperature. Wait for the inverter to reach
the proper temperature. Make sure the inverter is located in a sheltered envi-
ronment with a suitable operating temperature range.
W05
Sun low
The inverter is waiting for the photovoltaic energy level to become sufficient for
supplying to the network.
W07
External SPD Fault
One or more external over-voltage dischargers (SPDs) is/are faulty. Replace it/them.
W58
IN1 External Warning
Warning indication associated with digital input IN1.
W59
IN2 External Warning
Warning indication associated with digital input IN2.
W60
IN3 External Warning
Warning indication associated with digital input IN3.
W61
IN4 External Warning
Warning indication associated with digital input IN4.
