Insufficient generator volt-
age / insufficient battery
voltage!
Insufficient generator voltage and power, sta-
tus before the transition to night shutdown.
The DC voltage is
too low or the volt-
age is interrupted
under load (DC out-
put 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 iso-
lator 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.

Feed in at max. MPP
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.
Check whether: -
Strings with differ-
ent voltage levels
are present on the
same tracker. - XL
version: a DC isola-
tor 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 ac-
tive: check whether
open circuit voltage
is lower than the set
constant voltage

Self-test in progress
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 rou-
tines gets stuck.
If the device re-
mains in this status
continuously de-
spite adequate DC
voltage, this indi-
cates a device fault.
