The PZEM-051 is engineered specifically for direct current (DC) systems. It features a wide measurement range and requires an external shunt to measure current accurately without damaging the internal circuitry. Measurement Range Resolution 6.5V to 100V DC Current 0 to 100A (with included shunt) Power 0.1W ( Energy 0 to 9999kWh 1Wh ( Working Voltage: 6.5V DC to 100V DC Test Voltage: 6.5V DC to 100V DC Rated Power: 100A / 10000W Display Size: 51mm x 30mm Product Dimensions: 89.6mm x 49.6mm x 24.4mm Installation Cutout: 84.6mm x 44.6mm Screen Display and Layout
According to the Peacefair PZEM-051 manual: peacefair pzem-051 manual
: Supports up to 100A using an external 75mV shunt (often included). Rated Power : Up to 10,000W. Energy Metering : Tracks energy from 0 to 9,999kWh. Manual & Operational Guide The PZEM-051 is engineered specifically for direct current
This module is strictly for . Do not connect it to AC power. Rated Power : Up to 10,000W
Connect the positive (+) and negative (-) terminals of your battery or power source to the voltage measurement terminals on the back of the meter.
Connect to the source side of the external shunt (same physical side as Pin 2). Common Troubleshooting Steps Screen is completely blank Verify that the input voltage is above 6.5V DC.
