Output OC
The error appears when the in-
verter output current exceeds the
internal inverter alarm threshold.
This may be caused by:
a) High impedance grid with sig-
nificant voltage variations, even
with small loads.
b) Internal inverter fault
a) Check that the grid voltage is stable,
mainly upon:
- loading with high current peak loads.
- maximum power generation of the
PV system
If the grid voltage is unstable, verify
the appropriate sizing of the line
cable/s, and, if correct, please con-
tact your grid operator to address the
problem.
b) If no problems are found when
checking the grid voltage, the alarm
may be caused by internal inverter
faults.

OverTemp
High internal temperature record-
ed by the inverter. This parameter
depends in part on the power that
the inverter must supply, as the
internal inverter temperature is
affected by the heat dissipated
internally by its components. This
may be caused by:
a) Failure to observe the installa-
tion conditions
b) Internal inverter fault
a) Verify the installation conditions
(exposure to sunlight) and check that
air flow to the MICRO inverter is not
obstructed, so as to permit cooling of
the device. Check that the ambient
temperature measured around the
MICRO inverter does not exceed the
limits set in the technical data.
b) Verify the MICRO inverter tempera-
ture readings (see the Internal Web
Server section in the CDD manual). If
one of the temperatures remains at a
value which is not compatible with the
environmental conditions (e.g. -40°C
internal temp. reading with 20°C effec-
tive ambient temperature), the alarm
may be due to internal inverter causes.
