< Check grid and fuses >
The inverter has detected an error in the
AC cabling and cannot connect to the
electricity grid. The reason for this could
be an incorrect country setting. • Check AC installation
• Adjust the connection as described in
Section 6.3 "Connection to the
Electricity Grid (AC)" (page 29).
• Check that the country setting is correct:
– Via the rotary switch: see Section
6.5.1 "Checking the Country Data
Set" (page 44).
– Via communication: setting the
parameter "CntrySet" or "Set
country standard"
1501 < Reconnection fault grid >
The measured voltage or frequency is
too high or too low for connection to the
electricity grid.
Possibly, a changed country data set or
changed parameters do not correspond
to the local requirements for connecting
to the electricity grid. • Check that the country setting is correct:
– Via the rotary switch: see Section
6.5.1 "Checking the Country Data
Set" (page 44).
– Via communication: setting the
parameter "CntrySet" or "Set
country standard"
• Check whether the voltage and
frequency of the electricity grid are
within the limits of the configured
country data set.
• If individual parameters within a
country data set have been changed,
re-select the original country data set
for the installation country.
3301 …
3303 < Unstable operation >
There is not enough power at the DC
input of the inverter for stable operation.
This may be caused by snow on the PV
modules. • Wait for more irradiation.
• If this event recurs at medium
irradiation, check the PV plant design
and correct the circuitry of the PV array.
