2 Plugreen Solar micro-inverter System
The Plugreen Solar micro-inverter extracts maximum energy from individual photovoltaic (PV) panels.
Each Plugreen Solar micro-inverter is connected to individual PV module. This enables unique intelligent
Maximum Peak Power Point Tracker (iMPPT) of each PV module. By doing so, the single point of failure can
be avoided compared to a string inverter system.
Communication Gateway Unit can be plugged into any two pin standard outlet. The power supply to this unit
is universal so it works from 85 to 265VAC. This unit needs to be installed indoors. Once you connect the
AC power, connect Ethernet cable between the units and your broadband router or modem. Once you
install the Communication Gateway unit, it automatically starts communicating with the centralized web
server. Please log in to the data monitoring web server though Plugreen webpage to understand the data
logging systems and displays.
This integrated system maximizes energy harvest, increases system
reliability, and simplifies design, installation and management.

To connect your PV modules:
: Completely install all solar micro-inverters and all system inter-wiring connections prior to
installing the PV modules.
Best Practice: Test AC first. Before you rack-mount the PV, pull and terminate all AC wiring, energize the
branches, and power up the solar micro-inverters to make sure that they all report into the
Communication Gateway unit and are operating correctly.
Mount the PV modules above their corresponding solar micro-inverters. Each solar micro-inverter
comes with two oppositely sexed MC4 multi-contact connectors.
First connect the positive DC wire from the PV module to the negatively marked DC connector (female
socket) of the solar micro-inverter. Then connect the negative DC wire from the PV module to the
positively marked DC connector (male socket) of the solar micro-inverter. Repeat for all remaining PV
modules using one solar micro-inverter for each module.
