2 Introduction

LG AC module consists of PV(Photovoltaic) module and “Utility-Interactive” micro inverter. Without any additional equipment, it converts the solar energy to AC power used in electric appliances and supplies to the utility.

The Advantages of AC Module System

•The AC module system, unlike a central inverter system, operates with module MPPT. The AC module does not have any adverse effect on the other modules, allowing more power production in comparison to a central inverter system.

•Eliminates installations related to DC voltage, reducing total installation and labor costs.

•Maintenance is easy as the system can be monitored in real time.

1.AC module

-Consists of PV module and micro inverter.

-Performs MPPT function, maximizing power generation.

2.Communication gateway

-Collects information about AC module system via AC cable.

-Stores data inside.

-Uses wireless connection to transmit data to smartphone or tablet.

3.Monitoring

-Monitors and analyzes condition of the solar system.

-Transmits the condition of the system to the service center in case of a problem.

/MPPT : Maximum Power Point Tracking.
