Abstract: With more and more global energy demand, and under the premise of advocating environmental protection, solar photovoltaic power generation will definitely occupy a major position in the world energy consumption in the 21st century. This paper mainly introduces the application of Acrel DC energy meter in a solar panel company in Italy.Acrel DJSF1352-RN DC energy meter is mainly used for measuring and monitoring of DC signal equipment such as batteries on the DC side of the PV project.

 

1. Project Overview

     This project is for the application of battery monitoring in Italian photovoltaic industry, mainly using our company’s DC energy meter DJSF1352-RN, DC voltage sensor ACTDS-DV and shunt to monitor and measure 1300V battery.

 

2.Introduction of DC Energy Meter Product

     Acrel DC energy meter DJSF1352-RN is designed for DC screen, solar power supply, telecom base station, charging pile and other applications. This series of meters can measure voltage, current, power, forward and reverse energy in DC system.Can be used for local display, and can be connected with industrial control equipment, computer, measurement and control system.At the same time, it has a variety of peripheral interface functions for users to choose: RS 485 communication interface, modbus-RTU protocol;With relay alarm output, switching input/output.According to different requirements, through the meter’s panel buttons, to set and control the ratio, communication.
