This article describes the application of the Acrel DC meter in a photovoltaic system in Singapore. The device measures current, voltage and energy as well as the shunt.
Project overview
This company is based in Singapore and is the photovoltaic system installation company in Singapore. Mainly uses DC energy meter DJSF1352-RN and shunt, used to measure and monitor current and voltage in a PV system.
DJSF1352-RN Series DC Energy Meter
DJSF1352-RN series intelligent DC energy meter is designed for applications such as DC panels, solar power, telecommunications base stations and charging piles. This series of devices can measure voltage, current, power, forward and reverse power in a DC system. It can be used for local display and connected with industrial control equipment and computers to form a measurement and control system. And it has a variety of external excuse functions for the user to choose, RS485 communication interface, Modbus-RTU protocol, relay alarm output, digital input/output. According to the different requirements, through the instrument panel buttons, you can set the ratio, communication parameters. The product meets the relevant technical requirements of the standard Q/GDW1825-2013 DC power meter specification, GB/T29318-2012 non-vehicle charging electric energy measurement for electric vehicles, Q/GDW364-2009 single-phase energy meter specification.
