The
first
two
messages
are
about
the
PV
array
and
output
voltages
and
power.
Vpv
is
the
incoming
DC
voltage
from
the
PV
array.
Wpv
is
the
incoming
power
of
the
PV
array
in
Watts.
Vac,
Pac,
Iac,
and
Fac
are
the
voltage,
power,
current,
and
frequency
at
the
inverter
output.

Power
Derating
Message
There
are
five
possible
derating
messages
which
will
be
shown
if
the
power
is
derated
during
grid
feeding
mode.
Only
one
de
‐
rating
cause
is
displayed
at
a
time.
When
“Temp”
message
is
present,
the
power
derating
is
caused
by
an
over
temperature
of
the
heat
sink.
The
“Ipv”
message
shows
that
the
power
derating
is
caused
by
restricting
the
DC
input
current
to
the
maximum
limit.
The
“Iac”
and
“Pac”
messages
illustrate
the
power
derating
is
caused
due
to
a
restriction
of
the
maximum
output
AC
current
and
power.
The
“VacH”
message
shows
that
the
power
derating
is
caused
by
high
AC
voltage.
