Status description
Generatorspannung und -leistung ist zu gering,
Zustand vor Übergang vom oder zum Standby.
Search for the cause in the plant if insufficient
power is being fed in despite this message be-
ing issued. If irradiation is sufficient, MPP con-
trols are used for feed-in to gain maximum
yield.
Self-test of the relays, check the line relay
prior to beginning grid feed. Should only be re-
garded as an error if one of the self-test
routines gets stuck.
Test mode is for internal operations only!

Action
The DC voltage is
too low or the
voltage is interrup-
ted under load (DC
output too low)
a) Is the web inter-
face showing the
correct voltage
measured on the
terminals? (Note
measured values)
b) XL version: Check
whether the DC isol-
ator switch is
switched off.
c) Check whether
DC polarity reversal
is present.
d) Check whether
the device software
has been installed in
full via the list of
versions in the
menu.
Check whether: -
Strings with differ-
ent voltage levels
are present on the
same tracker. - XL
version: a DC isol-
ator switch is
switched off. - DC
polarity reversal is
present - frequent
power limitation
due to inadequate
dimensioning -
check open circuit
voltage with multi-
meter - if constant
voltage mode is act-
ive: check whether
open circuit voltage
is lower than the set
constant voltage
If the device re-
mains in this status
continuously des-
pite adequate DC
voltage, this indic-
ates a device fault.
