Ground fault The error is generated when a ground
leakage current is detected in the DC
section of the system. This may be
caused by:
a) PV module ground leakage
b) Internal inverter fault

DC Injection The error is generated if the DC
component of the current supplied to
the grid exceeds the threshold set by
the country of installation’s applicable
regulation. In any case, the inverter will
automatically try to reconnect to the
grid. This may be caused by:
a) Sporadic recurrence of this error is a
sign of large grid distortions or sudden
changes in irradiance.
b) Systematic recurrence of this error
may be due to an inverter fault. a) Verify the grid parameters and, if
the grid voltage is strongly distorted,
please contact your grid operator to
address the problem
If the grid voltage is stable, the error
may also be due to sudden irradiance
variations. In this case, the inverter
will automatically try to reconnect to
the grid and no actions are required to
solve the problem.
b) If the grid voltage is stable, yet the
error systematically persists, the mal-
function may be caused by an internal
inverter fault

Internal Error a) The alarm may occur during inverter
initialization and is caused by the
initialization of communication between
the CDD and the MICRO inverters.
b) Systematic occurrence of this error
may be due to an inverter fault. a) The alarm will automatically reset
upon connection of the inverter to the
grid, and no actions are required to
solve the problem.
b) If the error systematically persists,
the malfunction may be caused by an
internal inverter fault
