Grid Fail by the country of installation's
grid standard. The error code will

VAC OV (UV) Grid voltage below the set

Solution
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 de-
tected, verify the sizing of the AC line
conductors. In case of correct sizing,
please contact your grid operator to
address the problem.
Contact customer service.
If problem persists check grid connec-
tion condition.
If problem persists check grid frequen-
cy condition.
If problem persists check grid voltage
condition.
(UF) grid frequency below the set
lower limit
(OF) grid frequency above the upper
limit
