Explanation
ž The fault relay releases again.
ž The device feeds back into the grid again after a country-
specific time period.
Status description
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.
Insufficient generator voltage and power,
status before the transition to night shutdown.
In cases of sufficient sunlight, the unit feeds
into the grid with MPP control so as to maxim-
ise yields.
During the self-test, the following sequence is
run through: 1. S7 (start-up) 2. S75 (load DC
link) 3. S8 (relay and buffer test) Inverter ob-
jective is to switch to S4
Self test of relays, testing of line relays prior to
beginning grid feed
culation, the device switches off. Cause: ambi-
ent temperature too high, device error.
Power limitation: If the generator power is too
high, the device limits itself to the maximum
power (e.g. around noon if the generator ca-
pacity is too large).
The activated grid and system protection has
been tripped.
AFI shutdown as a result of a sudden residual
current in the system
There is an insulation fault on the PV gener-
ator. The feed-in was interrupted.
Internal ramp limiting, e.g.: "Ramp Up" 10 %/
Min • After an overvoltage has been detected,
for example, the device limits its output and
slowly ramps up again (RampUp).
