DC metering is used in specific applications to measure, collect, and store real-time data for DC power systems. It is widely used in various industries such as solar systems, EV charging stations, battery energy storage systems 

EASTRON DCM230/232 series DC energy meters are designed for measuring and monitoring in DC systems.  They are an ideal solution for measuring and monitoring in DC systems. The din rail DC energy meters can measure of important DC parameters: Voltage, current, power and energy etc. It also support bi-directional measurement with pulse output. All data in the meter are accessible via RS 485 using Modbus RTU. The meter has two versions working with AC or DC power supply. Input voltage range up to 1000V DC, and current inputs are flexible with DC shunt. The multi-tariff version has a RTC equipped inside, it can provides multi-tariff information and monthly records.
