Waiting for feed-in
The start voltage (pre-)set in the device is
higher than the actual voltage. The device
waits for the solar voltage to exceed an ad-
justable value and for a stable grid.
Check whether the
start voltage was
set too high in the
menu.

Insufficient generator voltage and power,
status before the transition to night shutdown.
Insufficient DC

fails under load (in-
sufficient DC power)
a) Compare the
voltage measured
with the no-load
voltage expected. b)
Check if the DC isol-
ator switch is
switched off c)

Constant volt. control
No MPP control occurs. When feed-in begins,
a constant generator voltage is fed in (85% of
the measured open circuit voltage) for a short
period
a) Does this status
appear in the morn-
ing and evening
when sunlight con-
ditions are poor? b)
Does this status ap-
pear when sunlight
conditions are
good? Please check
the constant voltage
control settings in
the menu. Internal

Yield counter for daily and
annual yields are displayed
In cases of sufficient sunlight, the unit feeds
into the grid with MPP control so as to maxim-
ise yields.
