Inverter Fault - Sunways AT 2700 User Manual

Display message Description
213:UAC1>10% The voltage of the phase feeding in is
(Warning) higher than 10% above the nominal
value. If this is the case for longer than
ten minutes, the inverter stops feeding
and does not switch on again until the
voltage drops below this limit again.
224:AC P. fail Your Solar Inverter has detected a mains
power failure.
225:ULL err Your Solar Inverter is equipped with a
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.

Inverter fault

301:AFI over The integrated sensor for measuring
the residual current has been operated
outside its measuring range.
302:Monit. The AT Solar Inverter is equipped with a
redundant monitoring device which con-
stantly checks the measured values of the
controller for plausibility. If a deviation
or an error is detected in the process, this
message appears. In addition, this mes-
sage can also appear in case of a power
failure.
Cause and possible remedies
The cable cross-section in the AC supply
line to the Solar Inverter is too small.
Your inverter feeds into a spur line,
which is insufficiently dimensioned.
· Check the design of your grid connec-
tion (energy meter) or the grid feed
point to your Electric Utility.
· Ask your Electric Utility about grid
stability and design.
· 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.
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.
