mismatch The alarm is generated when the grid
standard (selected on the CDD during
installation) has not been correctly set
on the MICRO inverters. This may be
caused by:
a) communication problems while set-
ting the grid standard for the MICRO
inverter from the CDD:
b) poor irradiance while setting the grid
standard for the MICRO inverter from
the CDD: MICRO inverters are directly
supplied by the voltage generated at
the panel, and poor irradiance may
cause inverter shut downs

fault The alarm is generated when the CDD
device does not receive messages
from the MICRO-inverter for more than
15 minutes. This may be caused by
non-optimal positioning of the CDD. Consider a new installation position
that ensures better communication
between the CDD device and the MI-
CRO-inverters. Use the CDD Internal

Vpanel Problem
This alarm is displayed when the input
voltage generated at the PV generator
is outside the allowed range given in
the technical data. This may be caused
by:
a) Poor sunlight
b) Possible shadows that may darken
the module during part of the day.
b) PV module incompatible with the
MICRO inverter input parameters
d) Internal inverter fault

c) Verify that the PV module voltage

positive results, yet the error persists,
the malfunction may be caused by the
MICRO inverter.
