Microinverter System Introduction
This
integrated
system
improves
safety;
maximizes
solar
energy
harvest;
increases
system
reliability,
and
simplifies
solar
system
design,
installation,
maintenance,
and
management.
Microinverters
maximize
PV
energy
production
Each
PV
module
has
individual
Maximum
Peak
Power
Tracking
(MPPT)
controls,
which
ensures
that
the
maximum
power
is
exported
to
the
utility
grid
regardless
of
the
performance
of
the
other
PV
modules
in
the
array.
When
PV
modules
in
the
array
are
affected
by
shade,
dust,
orientation,
or
any
situation
in
which
one
module
underperforms
compared
with
the
other
units,
the
Microinverter
ensures
top
performance
from
the
array
by
maximizing
the
performance
of
each
module
within
the
array.
More
reliable
than
centralized
or
string
inverters
The
distributed
Microinverter
system
ensures
that
no
single
point
of
system
failure
exists
across
the
PV
system.
Microinverters
are
designe
-
d
to
operate
at
full
power
at
ambient
outdoor
temperayures
of
up
to
149°F
(65°C).
The
inverter
housing
is
designed
for
outdoor
installation
and
complies
with
the
IP65
environmental
enclosure
rating.
Simple
to
install
You
can
install
individual
PV
modules
in
any
combination
of
Module
quantity,
orientation,
different
type
and
power
rate
The
Ground
wire
(PE)
of
the
AC
cable
is
connected
to
the
chassis
inside
of
the
Microinverter,potentially
eliminating
the
installationof
grounding
wire
(check
local
regulation).
Smart
system
performance
monitoring
and
analysis
The
Energy
Collect
Device
(ECD)
is
installed
by
simply
plugging
it
into
any
wall
outlet
and
providing
an
Ethernet
connection
to
abroadband
router
or
modem.
After
installing
and
setting
the
ECD(see
ECD
manual),
the
full
network
of
Microinverters
automatically
reports
to
the
Energy
Monitor
and
analysis
(EMA)
web
server.The
EMA
software
displays
performance
trends,informs
you
of
abnormal
events,
and
controls
system
shutdown
when
it
is
needed.
(See
ECD
manual
for
instructions.)
