This alarm is generated when one or
more grid parameters lie outside the
permitted range set by the country of
installation’s grid standard. The er-
URUFRGHZLOOEHIROORZHGE\DVXI¿[LQ
brackets indicating the grid parameter
out of range:
(UV) Grid voltage below the set lower
limit
(OV) Grid voltage above the set upper
limit
(UF) Grid frequency below the set
lower limit
(OF) Grid frequency above the set up-
per limit
If the error is generated only on one of
the installation MICRO inverters, this
may be due to an inverter fault.
If the alarm is generated at multiple
inverters in the installation, check the
grid voltage for instabilities in any of
the 4 parameters monitored by the
inverter. If anomalous values are
detected, verify the sizing of the AC
line conductors. In case of correct
sizing, please contact your grid
operator to address the problem.

Blinking green
Pgrid limitation
MICRO is limiting AC power due to an
external condition; not an error but a
certain working condition
If problem persists check grid
connection condition.
:
Blinking green
Pgrid Fgrid
limitation
MICRO is limiting AC power due
standard frequency regulation.
If problem persists check grid
frequency condition.
:
Blinking green
Pgrid VAC high
limitation
MICRO is limiting AC power due to a
standard voltage regulation.
If problem persists check grid voltage
condition.
:
Blinking green
Fgrid problem
(UF) grid frequency below the set
lower limit
(OF) grid frequency above the upper
limit
