Trip
Settings
The
inverter
is
designed
to
operate
within
certain
voltage
and
frequency
ranges,
as
specified
by
the
utility.
When
the
inverter
senses
that
the
inverter
and/or
grid
is
outside
any
of
these
ranges
the
inverter
ceases
exporting
power
and
disconnects
from
the
grid.
This
action
is
referred
to
as
an
inverter
trip.
