Application of DC energy meter in Photovoltaic battery project in Italy

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.AcrelDJSF1352-RN DC energymeter is mainly used for measuringand monitoringof DC signal equipment such as batteries on the DC side of thePVproject.

1.Project Overview

This project is for the application of battery monitoring in Italian photovoltaic industry, mainly using our company’s DC energymeter 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: RS485 communication interface, modbus-RTU protocol;With relay alarm output, switching input/output.According to different requirements, through the meter’spanelbuttons, to set and control the ratio, communication.
