Application Analysis of DC Multifunctional Electric Energy Meter in Photovoltaic System
With the increasing demand for global energy and on the premise of advocating environmental protection, solar photovoltaic power generation will surely occupy a major position in the world's energy consumption in the 21st century.
The photovoltaic power station DC detection meter is an intelligent and digital front-end acquisition element. The meter can have an RS-485 communication interface and use the Modbus-RTU protocol. Photovoltaic power station DC detection meter is designed for applications such as DC screen, large solar power supply, telecommunication base station, etc. This series of meters can measure the current in the DC system: voltage, power state and electric energy, which can be used for local display, and can be used with Industrial control equipment and computer connection to form a measurement and control system.
EM series DC energy meters are designed for applications such as DC panels, solar power supply, telecommunication base stations, charging piles, etc. This series of meters can measure voltage, current, power, forward and reverse energy in DC systems. It can not only be used for local display, but also can be connected with industrial control equipment and computer to form a measurement and control system. At the same time, it has a variety of peripheral interface functions for users to choose: with RS-485 communication interface, using DTL645/Modbus-RTU protocol; with relay alarm output, switch input/output. According to different requirements, set and control the transformation ratio and communication through the buttons on the instrument panel.
