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 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

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
routines gets stuck.
If the device re-
mains in this status
continuously des-
pite adequate DC
voltage, this indic-
ates a device fault.

Temperature in device too
high
Possible causes: ambient temperature too
high, fan covered, device fault.
Cool off the area
around the inverter.
Uncover the fans.
Notify your author-
ized electrician!

Power limitation
The heat sink temperature or control board
temperature is too high. This is a safety func-
tion to prevent possible damage due to high
temperatures.
Query the temper-
ature via the web
interface. Are air
outlets covered? Is
there sufficient
space at the ventila-
tion openings of the
device? See Chapter
6, Assembly and
preparation. If ne-
cessary, see that the
room is cooled.
