E022 Time taken to execute the au-
Self-Test Error 4 totest carried out on the relays of
Relay self- test the DC_AC circuit part (inverter)
timeout is too long. This may indicate
a problem associated with the
aforesaid relays.
E023 The error is generated if the di-
DC inj error rect component of the current
Dc-Injection out of supplied to the grid exceeds the
range threshold of 0.5% of the rated op-
erating current.
The error does not stop the in-
verter, instead tries to connect to
the grid again. Sporadic repetition
of the error is a sign of large grid
distortions or sudden changes in
sunlight, whereas systematic rep-
etition of the error warning will be
a sign of an inverter fault.
E024 Error inside the inverter
Internal error
Solution
Error inside the inverter that cannot be checked ex-
ternally. If the problem persists (after switching the
inverter off and then on again), contact customer
service.
If the grid voltage is strongly distorted, report this
anomaly to the utility company for the resolution of
the problem If there is an inverter fault, contact cus-
tomer service.
