The Peacefair PZEM-051 is a 4-in-1 DC multi-function meter designed to monitor voltage, current, active power, and energy consumption in real-time. Whether you are managing a solar array or a battery bank, this guide simplifies the often-confusing manual for quick setup and operation. Core Specifications & Measurement Ranges
The device is rated for high-precision (Class 1.0) monitoring within these ranges: Voltage: 6.5V to 100V DC.
Current: 0 to 100A (depending on the external shunt used, 50A or 100A). Active Power: 0 to 10kW. Energy Consumption: 0 to 9999kWh. Wiring and Installation
The meter requires an external 75mV shunt for current measurement. Important Safety & Usage Notes
The Peacefair PZEM-051 is a 4-in-1 DC digital multi-function meter designed to simultaneously measure and display voltage, current, active power, and energy consumption. Commonly used for monitoring solar panels, battery banks, and DC power systems, it features a large LCD with a blue backlight for high visibility in low-light conditions. Key Technical Specifications
The device is strictly for indoor use and handles a standard DC voltage range. Working/Test Voltage: 6.5 ~ 100V DC.
Measurement Range: 0 ~ 100A (depending on the external shunt used). Rated Power: Up to 10kW (10,000W). Accuracy: Grade 1.0.
Memory: Built-in storage retains energy data even during power outages. Wiring and Installation
Proper wiring is critical to avoid damaging the meter or your circuit. The
requires an external 75mV shunt resistor for measuring current above 10A.
Main Power: Connect the positive (+) and negative (-) terminals of your battery or power source to the voltage measurement terminals on the back of the meter.
Current Shunt: The shunt must be connected in series with the negative line to the load.
Signal Wires: Connect the two small terminals on the shunt to the corresponding current measurement ports on the meter.
B- (Battery side): Connects to the small bolt on the battery pack side of the shunt.
P- (Power side): Connects to the small bolt on the controller/load side of the shunt. Operating Instructions YouTube·Robojaxhttps://www.youtube.com Review of Peacefair PZEM-051 100A DC Current Power meter
One of the main advantages of the PZEM series is the ability to communicate with microcontrollers (Arduino, ESP8266, STM32, etc.).
5V, GND, RX, TX).The blue "donut" transformer (split-core current transformer) must be clamped around the Live (Load) wire of the circuit you wish to measure.
