2 General Introduction
Overview of AC-PLC KIT-800V/US
The AC-PLC KIT is widely applied in residential electricity information
collection, photovoltaic, smart home, industrial control and other fields.
The Grid-tied PV system is generally made up of PV modules, string PV
inverters, AC-PLC system, etc. as shown below.
Figure 2-1 The diagram of Grid-tied PV system
The AC-PLC KIT includes an outdoor cabinet, with RS485 signal lightning
arrester, PLC master module, intelligent communication gateway and relevant
power supplies and overcurrent protection devices. Together, they implement
and achieve the communication control function of the PV power station arrays,
collect the operating data of the inverters and other equipment in the system and
upload it to the remote monitoring system. Via the remote monitoring system,
users can access the WEB interface to view operation information and set
parameters.
