Product details
Description
The Eujgoov Peacefair PZEM-017 DC Consumption Meter is a modular energy monitoring device engineered for precision tracking of direct current electrical parameters. Lacking a built-in screen, this advanced communication module transmits real-time data seamlessly via an RS485 interface using the Modbus-RTU protocol, making it exceptionally versatile for integration with microcontrollers, computers, and custom monitoring systems like DIYBMS or Home Assistant.
It measures a wide DC voltage range from 0.05V to 300V and handles heavy-duty current requirements up to 300A depending on the external shunt specification chosen. Ideal for solar power installations, battery banks, electric vehicle projects, and DIY electronics hobbyists, this unit tracks active power, frequency, and cumulative energy consumption with a high 1 percent measurement accuracy.
The included USB adapter cable simplifies connection for configuration and data logging, giving engineers and technicians granular visibility into their power networks.
How to use
- Connect the module inline with your DC load path using the appropriate external shunt.
- Wire the RS485 communication lines to a host computer via the included USB adapter or a microcontroller like an Arduino or ESP32.
- Ensure an independent power supply is used if the test voltage falls below 7V, and configure your software using the Modbus-RTU protocol to read voltage, current, and energy data.

sach me badiya kaam kiya
was skeptical at first buying a screenless meter online coz setting up modbus rtu protocol can be headache sometimes. par bhai ye to ekdum mast nikla. apne home assistant system ke sath easily integrate ho gaya aur battery bank ka data exact bata raha hai. tension free hogya me.
FAQs
What is your intended shunts rating (50A, 100A, 200A, or 300A)?
The current measurement range depends entirely on the external shunt specification you select and connect to the device. You can choose from 50A, 100A, 200A, or 300A variants to match your specific power monitoring requirements.
What microcontroller or software (e.g., Arduino, ESP32, Home Assistant) are you using to read the RS485 data?
The PZEM-017 communicates via an RS485 interface using the Modbus-RTU protocol, allowing it to integrate smoothly with microcontrollers like Arduino and ESP32 or custom home automation software using standard serial libraries.
Does this meter have a built-in display screen?
No, this module does not feature a physical screen. All measurements must be read externally through a connected computer, microcontroller, or display device using the RS485 communication interface.
Are these imported USA products authentic when buying from Dropy India?
Yes, Dropy sources all products directly from the United States to ensure complete authenticity and high quality for Indian customers.
What power supply is needed if the test voltage is very low?
When testing DC voltages below 7V, you must use an independent power supply mode to ensure proper operation and accurate measurement by the device.
