2 Introduction

LG AC module consists of a DC module and a micro inverter. Without any additional equipment,
it converts the solar energy to AC power which can be consumed by electric appliances in a home
or can be supplied to the utility.
The Advantage of AC Module System
The AC module produced by LG Electronics is delivered after completing the connection
between DC module and a micro inverter, which eliminates installation steps connecting a micro
inverter to a DC module. Thus, steps for the connection of DC module and a micro inverter can be
excluded.
Also, the AC module provides better flexibility for building PV arrays. The AC module is
equipped with two separate AC cable connectors (male and female). Thus the two AC cable
connectors enable landscape or portrait orientation without requirement of any trunk cables. Even
though there are roof vents on the target site, there is no worry because AC cable connection is
possible for the AC module array circumventing the vent area.
The mentioned advantages will reduce total installation and labor costs. Also, total installation
time will be shortened.

In this diagram, AC modules will produce power during daytime. The produced energy can be
consumed by home appliances like a fridge, TVs, and etc. Or if the power generation is more than
total power consumption in the house, the power will flow to the grid. Power flow is described
as .
The EnerBox2 utilizes power line communication (PLC) method to collect data from each AC
modules. The PLC matters to communication between micro inverters and a EnerBox2. The PLC
signal is depicted as
The EnerBox2 sends data to the web server through a home router. Internet connection of the
EnerBox2 is possible with Wi-Fi or a LAN cable. Wireless communication is described as
