The 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
Missing from manual: There is no "Reset Total Energy" button. You must disconnect power to the meter for 10 seconds to clear the internal EEPROM (undocumented feature). peacefair pzem-051 manual
