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
A
nalysis (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.)
