Operating Instructions Powador 3200 / 4400 / 5300 / 5500 / 6600_EN
Explanation
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.
The residual current is too high. The integrated AC/DC-sensitive residual current
circuit breaker registered an impermissibly high leakage current going to PE.
Insulation resistance from PV-/PV+ to PE is too low.
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.
An error has occurred in the AC/DC-sensitive residual current circuit breaker.
The internal grid separation relay test has failed. If this internal error occurs several
times, notify your authorised electrician.
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.
A communication error has occurred in the internal data transmission. Notify your
authorised electrician to check the data cable.
Protection shutdown of the software (AC overvoltage, AC overcurrent, DC link
overvoltage). This is not an error, but instead a grid-related shutdown.
Protection shutdown of the hardware (AC overvoltage, AC overcurrent, DC link
overvoltage). This is not an error, but instead a grid-related shutdown.
The voltage of the PV generator is too high. The PV array is incorrectly dimen-
sioned. Notify your authorised electrician.
The voltage of a grid phase L1 is too low, the grid cannot be fed into.
The voltage of a grid phase L1 is too high, the grid cannot be fed into.
The voltage of grid phase L2 is too low, the grid cannot be fed into (only for
active 3-phase monitoring).
The voltage of grid phase L2 is too high, the grid cannot be fed into (only for
active 3-phase monitoring).
The voltage of grid phase L3 is too low, the grid cannot be fed into (only for
active 3-phase monitoring).
The voltage of grid phase L3 is too high, the grid cannot be fed into (only for
active 3-phase monitoring).
The phase angle between the individual phases and the three-phase supply
network is not correct (only for active 3-phase monitoring).
The line frequency is too low. This error can be grid-related.
The line frequency is too high. This error can be grid-related.
The grid voltage measurement according to EN 50160 has exceeded the maxi-
mum permitted limit value. This error can be grid-related.
After a fault, the inverter waits a defi ned country-specifi c time period before it
can switch back on.
The temperature inside the unit was too high. The inverter switches off to prevent
damage to the hardware. Provide suffi cient ventilation.
An error occurred during the buffer inspection.
An error occurred in the EEPROM.
An error with no parameters.
