DC Energy Meter


HOP DJZ1737 is a 1-6 channel direct current smart energy meter designed with advanced energy metering chip and SMT technology. With RS485 port, the meter can communicate with the computer to exchange the data. The meter is widely used widely used for monitoring and controlling energy flow in DC systems such as solar PV energy, wind turbine power and other DC applications. The meters measure the voltage, current, power and energy parameters. Readings are displayed on the backlight LCD display and 3 months’ history data can be stored for energy analysis. The model DJZ1737 offers integration with external systems by MODBUS RTU protocol and an on-board RS485 serial communication port.


1. Multi-loop DC energy measuring with up to 6 loops.

2. Each loop meter can measure the current combined energy, individually measure current, voltage, energy,  power and electricity consumption of current month, 

3. Recording and alarming events like undervoltage, overvoltage, power failure , etc.

4. Meter will automatically do the energy settlement on the auto meter reading day of each month. Data of last 24 months will be saved.

5. Storing data of current, power, energy, time once every minute

6. Freezing data of current, power, energy, time once every hour

7. Storing monthly freezing energy of each month, the storage quantity is 24

8. Data inside the meter can be read through RS485 interface

9. Supporting broadcast time calibration. Remote time calibration can be realized through RS485 interface

10. Function of remote communication, telemetry, remote monitor, remote regulation
