Explanation
10
Temperature inside
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 the inverter is defective.
18
Error current
switch-off
The residual current is too high. The integrated AC/DC-sensitive residual current
circuit breaker registered an impermissibly high leakage current going to PE.
19
Generator insulation fault
Insulation resistance from PV-/PV+ to PE is too low.
30
Error
Measurement
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 feed-in
power and high feed-in power occur.
31
RCD module error
An error has occurred in the AC/DC-sensitive residual current circuit breaker.
32
Fault
Self test
The internal grid separation relay test has failed. If this internal error occurs several
times, notify your authorised electrician.
33
Fault
DC feed-in
The DC feed-in has exceeded the permitted value. This DC feed-in 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
Fault
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
Fault
PV overvoltage
The voltage of the PV generator is too high. The PV array is incorrectly dimen-
sioned. Notify your authorised electrician.
41
Line failure
Undervoltage L1
The voltage of a grid phase L1 is too low, the grid cannot be fed into.
42
Line failure
Overvoltage L1
The voltage of a grid phase L1 is too high, the grid cannot be fed into.
43
Line failure
Undervoltage L2
The voltage of grid phase L2 is too low, the grid cannot be fed into (only for
active 3-phase monitoring).
44
Line failure
Overvoltage L2
The voltage of grid phase L2 is too high, the grid cannot be fed into (only for
active 3-phase monitoring).
45
Line failure
Undervoltage L3
The voltage of grid phase L3 is too low, the grid cannot be fed into (only for
active 3-phase monitoring).
46
Line failure
Overvoltage L3
The voltage of grid phase L3 is too high, the grid cannot be fed into (only for
active 3-phase monitoring).
47
Line failure
line-to-line voltage
The phase angle between the individual phases and the three-phase supply
network is not correct (only for active 3-phase monitoring).
48
Line failure: underfreq.
The line frequency is too low. This error can be grid-related.
49
Line failure: overfreq.
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 maxi-
mum permitted limit value. This error can be grid-related.
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 board
The temperature inside the unit was too high. The inverter switches off to prevent
damage to the hardware. Provide suffi cient ventilation.
59
Self test error
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.
