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. Current combined energy consumption and current monthly consumption can be separately measured for each channel.

2. Measure current, voltage, consumption and power of each channel.

3. Record and alarm of under-voltage, over-voltage, power-failure, etc.

4. Automatic reading monthly with latest 24 months 'data stored

5. The data of current, power, consumption, time (year, month, day, hour, minute, second) will be stored once a minute and 1500 records can be stored for each item of each channel.

6. The data of current, power, consumption, time (year, month, day, hour, minute, second) will be frozen once an hour and 1500 records can be stored for each item of each channel.

7. Store monthly frozen energy with storage capability of 24 records

8. Record and store the latest 500 alarm records

9. Local storage function to avoid energy data loss

10. Data inside the meter can be read via RS485 port

11. Remotely broadcast time to the meter via RS485 communication port

12. With the function remote sign, remote measure, remote control, remote adjust

13. RS485 interface Baud rate can be set as 600-9600bps; Meter communication default parameter: 2400, N, 8, 1
