Error 027
· Grid overvoltage 3-phase
Your Solar Inverter is equipped with an
intrinsically safe 3-phase grid monitoring
system that complies with E DIN VDE 0126-
1-1. The voltage level of phases L1, L2, and
L3 is continuously monitored. If it rises
above the maximum admissible limit value,
the Solar Inverter will stop the injection
and only restart when the voltage value
drops below the maximum admissible
limit value.
Errors 028 to 030
· Surge fault
Your Solar Inverter continuously monitors
the quality of the AC grid. If there are high
voltage peaks in the grid, the Solar Inverter
will stop the injection and try to restart.
If such a surge impulse is detected at
energy unit 3, for example, «error 030»
will be flagged.
Errors 031 to 033
· Grid overvoltage > 10 percent
If the voltage of the injecting phase has
exceeded 253 V for more than ten minutes,
the Solar Inverter will stop the injection
and only try to restart when the grid
voltage is within the admissible range
again. The functioning method complies
with E DIN VDE 0126-1-1. If the applied
grid voltage at phase L2 is higher than
253 V for more than 10 minutes, for
example, «error 032» will be flagged.
Errors 034 to 036
· Control fault
Your Solar Inverter is equipped with a self-
monitored micro controller as a standard
feature. If a fault occurs in the control
sequence, the Solar Inverter will stop the
injection and will only restart when the
fault has been eliminated. If a fault occurs
in the control circuit board of the third
energy unit (upper energy unit), for exam-
ple, «error 036» will be flagged.
