Cause Remedy
Err 9
Too many inverters are connected. If
too many inverters are connected to the
communications bus then correct func-
tioning can no longer be guaranteed.
Limit the number of interconnected
inverters per row to a maximum of 5.
Connect the remaining inverters to their
own monitoring unit.
1)
Err 10
More than 4 sensors are connected. Limit the number of sensors to a
maximum of 2 irradiation sensors and 2
temperature sensors.
Err 11
The total AC power exceeds the maxi-
mum permissible value.
Limit the number of interconnected
inverters per row to a maximum of 5.
Connect the remaining inverters to their
own monitoring unit. 1)
Err 12 –
Err 16
Internal fault This can be a temporary problem with an
external cause. Check to see if the mes-
sage disappears after 48 hours. If this is
not the case then notify the installer.
Err 17 –
Err 24
— Not used.
Err 25
No connection to the remote display.
In the case of atmospheric interference
and poor transmission conditions the
communication can be interrupted for
brief periods. In this case, wait until the
conditions have improved.
Battery fault
: Check the batteries; try a
new set of batteries.
No reception : Attempt to achieve a
connection with the remote display in a
different position. 2)

Err 26
The display has not been configured
for a monitoring unit. This means that
the display has not yet been installed
in a monitoring unit while the unit was
initially commissioned.

and perform initial commissioning on
this unit 3) .
Err 27
Internal fault Notify the installer.
Err 28
–
Err 39
Not used
Err 40
The grid voltage lies outside the permis-
sible tolerance range.
Grid frequency variations are rare In
Europe. The error message therefore
usually relates to a complete absence of
voltage.
No error : When switching on the
inverter, this message may be displayed
and then disappear after approx. 10
seconds.
Poor contact : Check that all plug con-
nections between the inverters and the
monitoring unit are correctly installed
and their pin contacts are ok. The in-
verter number provides an indication of
the location of the faulty connection.
The LED of the affected inverter does
not illuminate constantly but rather
flashes briefly.
