Inverter Fault - Sunways NT 2500 User Manual

Display message Description
224:AC P. fail Your Solar Inverter has detected a mains
power failure.
225:UV excon You Solar Inverter is equipped with a
226:OV excon high-quality redundant grid monitoring
function according to DIN VDE 0126-1-1
and constantly monitors the grid. If one
of the phases fails, or if the phase posi-
tion between the individual conductors
changes, the Solar Inverter stops feeding
and does not start up again until the
error is eliminated.
227:L1 Your Solar Inverter continuously moni-
tors the output current. Excessive current
rise was detected.

Inverter fault

301:AFI over The integrated sensor for measuring
the residual current has been operated
outside its measuring range.
303:Overtmp. Your Solar Inverter is designed for an
ambient temperature of up to +45°C.
When a specified temperature threshold
of the heat sink is reached, the out-
put power is reduced linearly. Should
the heat sink temperature neverthe-
less continue to increase, feeding is
stopped. After the heat sink temperature
drops, the Solar Inverter starts up again
automatically.
Cause and possible remedies
· Ask your Electric Utility about grid
stability and design.
· Check phases L2 and L3.
· Ask your power supply company (PSC)
about grid stability and design.
· Ask your power supply company (PSC)
about grid stability and design.
A residual current was detected during
start-up.
· Restart the Solar Inverter.
If the error still occurs, please contact the
technical hotline. The phone number is
provided on the back of the manual.
The maximum permissible ambient tem-
perature has been exceeded.
· The installation location is not suit-
able. Please find another installation
location.
The necessary air circulation was not
taken into account during installation.
· Clean the Solar Inverter, if dirt pre-
vents cooling.
· Observe the installation distances
specified in the manual.
Objects were laid on the heat sink and
unimpaired convection was prevented.
· Remove the objects.
