What is a DC energy meter?

The DC energy meter is an instrument designed for applications such as DC panels, solar power supply, telecommunications base stations, DC charging station, and battery energy storage systems. It can measure the voltage, current, power, and forward and reverse energy in the DC system. The following is a detailed analysis of the DC energy meter:

Main functions and features

Wide measurement range: DC energy meter can measure DC current (such as 0~10A, an external shunt is required beyond this range), DC voltage (such as 5~1000Vdc), DC power and DC power, etc.

High precision: Its measurement accuracy can usually reach ≤±0.5%, ensuring the accuracy of the measurement results.

Multiple display modes: It uses a positive five-digit LED digital tube display, automatic range conversion, and automatic decimal point shift, which is convenient for users to read data.

Communication interface: Equipped with RS485 communication interface, supports Modbus-RTU protocol, can be connected to industrial control equipment and computers to form a measurement and control system, and realize remote monitoring and data transmission.

Multi-power adaptability: The working power supply can be selected from DC12V, DC24V, DC48V, DC110V, DC220V, etc. to meet the needs of different application scenarios

In energy storage systems, the application of DC energy meters in particular is very critical. DC energy meters are mainly used to measure and monitor the use of electricity in energy storage systems, and are essential to ensure the effective operation and energy management of the system. In container-type lithium battery energy storage systems, rail-type DC energy meters are particularly widely used because they are easy to install and can provide forward and reverse, 1-2-way energy metering and basic communication interfaces to meet the energy metering and monitoring needs of energy storage cabinets.
