How the Microinverter Works

The Sunshine Microinverter maximizes energy production from your photovoltaic (PV) array.
Each Sunshine Microinverter is individually connected to one PV module in your array. This
unique configuration means that an individual Maximum Peak Power Point Tracker (MPPT)
controls each PV module. This insures that the maximum power available from each PV
module is exported to the utility grid regardless of the performance of the other PV modules
in the array. That is, although individual PV modules in the array may be affected by shading,
soiling, orientation, or module mismatch, the Sunshine Microinverter insures top
performance for its associated PV module. The result is maximum energy production from
your PV system.

System Monitoring

Indoors, you can install the Microinverter Energy collecting device by plugging it into the
same wire wall socket and providing an Ethernet connection to your broadband router or
modem. After installation of the ECD, the full network of Sunshine Microinverters
automatically begins reporting to the Sunshine Microinverter Energy monitoring and
analyzer web server. The ECD software presents current and historical system performance
trends, and it informs you when the PV system is not performing as expected.

Optimal Reliability

Sunshine Microinverter systems are also inherently more reliable than centralized or string
inverters. The distributed nature of a microinverter system ensures that there is no single
point of system failure in the PV system. Sunshine Microinverters are designed to operate at
full power at ambient temperatures as high as 65C (150F). The inverter housing is designed
for outdoor installation and complies with the NEMA6 environmental enclosure rating
standard: NEMA6 rating definition: Indoor or outdoor use primarily to provide a degree of
protection against hose-directed water, and the entry of water during occasional temporary
submersion at a limited depth, and damage from external ice formation.

Ease of Design

PV systems using Sunshine Microinverters are very simple to design and install. You will not
need string calculations, and you can install individual PV modules in any combination of
module quantity, type, age and orientation. You won’t need to install cumbersome centralized
or string inverters. Each microinverter quickly mounts on the PV racking, directly beneath
each PV module. Low voltage DC wires connect from the PV module directly to the
co-located microinverter, eliminating the risk of personnel exposure to lethal 600Vdc power.
