Abstract: This paper introduces the application of Acrel DJSF1352-RN DC energy meter in the DC side of a photovoltaic system in Nigeria. It is mainly used to measure the DC current in the photovoltaic system, and cooperate with hall current sensor to measure, communicate and co
1.Project Overview
The company is located in Nigeria and is a new energy company. Mainly engaged in photovoltaic power generation projects in Africa. The customer wants to use DC meters and hall sensors for monitor current and voltage at the DC side of photovoltaic system.
2. DJSF1352-RN DC Energy Meters
DJSF1352-RN rail-mounted DC power meter designed for telecommunications ba
The meter can have infrared communication interface and RS-485 communication interface, and supports Modbus-RTU protocol and DLT645-97 (07) protocol at the same time.The meter can have relay alarm output and digital input function;You can set the ratio, alarm, and communication through the meter panel keys according to different requirements.The meter can have event recording of switch (Modbus protocol), programming and event setting records (645 protocol), instantaneous and timing freeze function of data (645 protocol), maximum and minimum value recording function of voltage and current power.
3. Type and Function Des
Note：when dual DC input（D）function is selec
current channel,a power supply module shall be provided to supply power to the second Hall sensor;if D function is not provided,the built-in power supply of electric meter can be used.
4.Split Core Hall Current Transformer
5. Customer Requirement
The customer have a solar hybrid system. PV panel, battery storage and diesel generator for a telecom station，All the 3 systems are co
