Introduction
The
PVI
6500
and
PVI
7500
are
single
phase,
grid
‐
tied
PV
inverters
designed
to
be
interconnected
to
the
electric
utility
grid.
By
following
the
instructions
in
this
manual,
the
PVI
6500
‐
PVI
7500
can
be
installed
and
operated
safely.
This
installation
guide
is
to
be
used
as
reference
for
commissioning
and
as
a
guideline
on
how
to
use
the
inverter
most
effectively.
Feeding
power
onto
the
grid
involves
conversion
of
the
DC
‐
voltage
from
the
PV
‐
array
to
grid
compatible
AC
‐
voltage
by
“inverting”
DC
to
AC.
This
unit
feeds
power
into
a
standard
240
VAC
split
phase
electrical
system
or
two
phases
of
a
208
VAC,
3
‐
phase
commercial,
industrial
or
institutional
facility’s
electrical
system
that
is
connected
to
the
electric
utility
grid.
The
inverter
can
also
be
connected
to
one
phase
and
neutral
of
a
277
VAC
electrical
service.
If
the
PV
system
and
inverter
are
providing
the
same
amount
of
electrical
power
that
the
facility
is
using,
no
power
is
taken
from
or
fed
onto
the
utility
grid.
If
the
facility
is
using
more
power
than
the
PV
system
is
providing,
then
the
utility
grid
provides
the
balance
of
power.
If
the
facility
is
using
less
power
than
the
PV
system
is
generating,
the
excess
is
fed
into
the
utility
grid.
Be
sure
to
look
into
local
regulations
regarding
net
metering
and
interconnection
in
your
local
area.
Note
that
some
utilities
need
to
change
their
revenue
kWh
meter
to
a
bi
‐
directional
type
for
proper
net
metering
measurement
or
incentives/billing.
