The PZEM-031 DC Energy Meter is a compact, panel-mount digital multimeter designed to give you total visibility into your DC electrical systems. Featuring a clear, backlit LCD screen, this all-in-one monitor simultaneously displays real-time voltage, current, active power, and total energy consumption, allowing you to track system performance at a glance.

Unlike models that require external components, the PZEM-031 features a built-in shunt, making it incredibly simple to wire inline with your load. It operates over a wide voltage range of 6.5V to 100V and can handle continuous currents up to 20A. It also includes smart features like a programmable voltage alarm and non-volatile memory that saves your accumulated energy data even if power is disconnected.

Perfect For:

  • Solar & Off-Grid Systems: Monitor the output of small solar panels, charge controllers, and 12V/24V battery banks in real-time.

  • RVs & Marine Applications: Keep a close eye on the power consumption of auxiliary 12V circuits, lighting, and appliances.

  • DIY Electronics Workbenches: Build a permanent monitoring panel for your custom DC power supplies and test stations.
