4.1 Troubleshooting
This guide provides tables showing messages appearing in
the inverter display, known as events. The tables contain
descriptions as well as which actions to take, when an
event arises. For the full event list, refer to the FLX Series
User Guide.
To view events, go to the Log menu and enter the
Eventlog menu. The latest event registered by the inverter,
as well as a list of the 20 most recent events, is shown
here. When the inverter enters the On grid mode, the most
recent event is cleared and is shown as 0.
The event code is made up of 2 elements: the group
classifier and the event ID. The group classifier describes
the general type of the event, while the event ID is used
to identify the specific event.
Table 4.1 is an overview of how the tables of inverter
events are constructed and how to use them.

Check the inverter is not covered and that the
ventilation duct is not blocked. If not, call installer.

Table 4.1 How to Read the Event Tables
Event Type Indicates whether the event relates to grid, PV, internal or fail safe issues.
ID The specific event ID.
Display Text shown in display.
Description Description of the event.
Action Description of which action to take prior to contacting any other parties.
DNO If the prescribed action has not identified the malfunction, contact the DNO for further assistance.
Hotline If the prescribed action has not identified the malfunction, contact the inverter hotline for further assistance.
PV If the prescribed action has not identified the malfunction, contact the PV supplier for further assistance.
Grid-related Events
ID Status
message Description Action DNO Hotline PV
1–6 Grid voltage too low. Call the installer and inform about the grid-phase voltage.
Check voltage and AC installation, if the voltage is zero
check the fuses.
x - -
7–9 Grid voltage average over 10
minutes too high.
Call the installer and inform about the grid-phase voltage.
Check that the installation is correct according to the instal-
lation guide. If so, then increase the mean voltage limit
according to section Functional Safety.
x - -
10–15 Grid voltage too high.
Call the installer and inform about the grid-phase voltage.
Check voltage and AC installation.
x - -
16–18 The inverter has detected a
voltage peak on the grid.
x - -
19–24 Grid frequency too low or too
high.
Call the installer and inform about the grid frequency.. x - -
25–27 Loss of mains, Phase-to-phase
voltages too low.
Call the installer and inform about the voltage on all three
phases.
Check the phase-to-phase voltages and the AC installation.
x - -
28–30 Loss of mains, ROCOF out of
range.
If the event reoccurs several times each day, contact the
DNO.
x - -
31–33 DC grid current too high. For occurrence several times daily, contact installer.
Installer: Perform on-site grid analysis.
