increased DC component is detected in the
fed-in current. The solar inverter only
attempts to feed again after a reset (the
next day).
Fault 12
· Isolated operation
Your solar inverter is equipped with high
quality redundant grid monitoring according
to DIN V VDE V 0126-1-1 and constantly
monitors the grid. If one of the monitored
phases drops out, or if the phase position
between the individual conductors changes,
the solar inverter stops the feed and only
restarts when the error has been eliminated.
Fault 13
· Grid overvoltage, 3-phase
Your solar inverter is equipped with intrin-
sically safe 3-phase grid monitoring accor-
ding to DIN V VDE V 0126-1-1. The voltage
level of phases L2 and L3 is constantly
monitored. If the level exceeds the maxi-
mum permissible limit value, the solar
inverter stops the feed and only restarts it
when the voltage value falls below the
maximum permissible limit value.
Fault 14
· Surge error
Your solar inverter constantly monitors the
quality of the AC grid. In the event of high
voltage peaks in the grid, the solar inver-
ter stops the feed and attempts to restart.
Fault 15
· Grid overvoltage > 10 %
If the voltage of the fed-in phase excee-
ded 253 V for a period of ten minutes, the
solar inverter stops the feed and attempts
to switch on again when the grid voltage
is in the permitted range. The mode of
functioning complies with DIN V VDE V
0126-1-1.
Fault 16
· Control error
Your solar inverter is equipped with a
self-monitored microcontroller. If an error
occurs in the control cycle, the solar inver-
ter stops the feed and only switches on
again when the error is eliminated.
