Microinverter System Introduction
This integrated system improves safety, maximizes solar energy harvest, and increases system
reliability. It also 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 transmitted 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 under performs compared with the other units, the
microinverter ensures peak performance from
the
array by maximizing
the
performance
of each
module.
More reliable than centralised or string inverters
The distributed microinverter
system
ensures that no
single
point
of
failure exists across the PV
system.
Microinverters are
designed
-
to operate
at maximum
power
within ambient outdoor
temperatures
, including
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
Individual PV modules can be installed 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 the
microinverter. This may potentially
eliminate the installation of a
grounding wire (check
this with local regulation).
Smart system performance monitoring and analysis
The
Data Monitoring Unit (DMU) is installed by simply plugging
it
into any
wall outlet,
and
providing
an Ethernet connection
to a broadband router
or modem. After
installing
and
setting-up
the
DMU
(see
DMU
manual), the full network of
microinverters
automatically reports
to the Energy
Monitor
and
Analysis (EMA)
web server. The
EMA
software
displays performance
trends, alerts the user to
abnormal events, and controls system shutdown when required (See DMU manual for instructions.)
