usually requires an external shunt (e.g., 50A or 100A / 75mV). The shunt is typically installed on the negative line to measure current. Measurement

To correct this without buying a new meter, you can desolder the internal sampling resistors or implement an external operational amplifier (Op-Amp) circuit to scale the millivolt output of your custom shunt back down to the 75mV maximum that the PZEM-051 expects at full load. 4. Comprehensive Wiring Diagrams

Because the PZEM-051 uses UART, you cannot simply plug it into Wi-Fi. You need a "bridge." The ESP8266 (like a NodeMCU or Wemos D1 Mini) is the standard choice. The shunt is typically installed on the negative
