202:UAC1>10% If the voltage of the phase
feeding in was greater than
253 V for a period of ten mi-
nutes, the solar inverter stops
feeding and attempts to switch
on again when the grid vol-
tage is within the permissible
range. The mode of operation
is conformant with DIN VDE
0126-1-1. The cable cross-section in the
AC supply line to the solar
inverter is too small.
Your inverter feeds into a spur
line, which is insufficiently
dimensioned.
➡
Check the design of your
grid connection (energy
meter) or the grid feed point
to your Electric Utility.
➡
Ask your Electric Utility
about grid stability and de-
sign.

203:UCA1>15% Your solar inverter continually
monitors the voltage level of
the phase feeding in. When
the maximum permissible limit
is exceeded, the solar inverter
stops feeding and does not
start up again until the voltage
value drops below the maxi-
mum permissible limit. The cable cross-section in the
AC supply line to the solar
inverter is too small.
Your inverter feeds into a spur
line, which is insufficiently
