Explanation
10
Temperature too
high in unit
If the inverter overheats due to a lack of air circulation, the inverter switches
off. This can occur if the ambient temperature is too high, the cooling fi ns
are covered, or if the inverter is defective.
29
Ground fault
Check the fuse!
A ground fault was detected on the DC side. Check the solar genera-
tor (can be switched on via a display entry) and notify your authorised
electrician.
30
Fault
in voltage transformer
The current and voltage measurements in the inverter are not plausible. This
can be caused by very dynamic weather conditions if quick changes between
low grid feed power and high grid feed power occur.
32
Error
Self test
The internal grid separation relay test has failed. If this internal error occurs
several times, notify your authorised electrician.
33
Error
DC grid feed
The DC grid-feed has exceeded the permitted value. This DC grid-feed can
be impressed from the grid on the Powador inverter so that no inverter fault
exists. If this error occurs several times, notify your authorised electrician.
34
Error
Communication
A communication error has occurred in the internal data transmission. Notify
your authorised electrician to check the data cable.
35
Protection shutdown (SW)
Protection shutdown of the software (AC overvoltage, AC overcurrent, DC
link overvoltage). This is not an error, but instead a grid-related shutdown.
36
Protection shutdown (HW)
Protection shutdown of the hardware (AC overvoltage, AC overcurrent, DC
link overvoltage). This is not an error, but instead a grid-related shutdown.
38
Error
PV overvoltage
The voltage of the PV generator is too high. The solar generator is incor-
rectly dimensioned. Notify your authorised electrician.
41
Line failure
Undervoltage
The voltage of a grid phase is too low, the grid cannot be fed into. The
phase in which the fault occurs is displayed in each case.
42
Line failure
Overvoltage
The voltage of a grid phase is too high, the grid cannot be fed into. The
phase in which the fault occurs is displayed in each case.
48
Line failure
Underfrequency
The line frequency is too low. This error can be grid-related.
49
Line failure
Overfrequency
The line frequency is too high. This error can be grid-related.
50
Line failure
Average voltage
The grid voltage measurement according to EN 50160 has exceeded the
maximum permitted limit value. This error can be grid-related.
51
Line failure
Overvoltage L1
Phase voltage L1 is above the set maximum permitted phase voltage.
52
Line failure
Undervoltage L1
Phase voltage L1 is below the set maximum permitted phase voltage.
53
Line failure
Overvoltage L2
Phase voltage L2 is above the set maximum permitted phase voltage.
54
Line failure
Undervoltage L2
Phase voltage L2 is below the set maximum permitted phase voltage.
55
Error
DC link
The voltage at the DC link is too high, or the DC link cannot be charged
(IGBT damage).
57
Waiting for
reconnect
After a fault, the inverter waits a defi ned country-specifi c time period
before it can switch back on.
58
Overtemperature
Control card
The temperature inside the unit was too high. The inverter switches off to
prevent damage to the hardware. Provide suffi cient ventilation.
59
Error
Self test
An error occurred during the buffer inspection.
Error (EEPROM)
No parameters
An error occurred in the EEPROM.
ERROR
No parameters
An error with no parameters.
