DC Energy Monitor – 300A, Bi-Directional Meter with Shunt for Voltage, Power & Monitoring

This DC Energy Monitor is a high-accuracy 4-in-1 watt meter designed to measure voltage, current, power, and energy consumption in DC systems. With a wide measurement range of up to 300V and 300A, it is ideal for solar panels, battery banks, inverters, EV systems, and DIY power projects.

The bi-directional measurement feature accurately tracks forward and reverse energy flow, while the built-in shunt ensures up to 99% accuracy without external components. A clear LCD with green backlight provides excellent visibility, and data storage ensures readings are saved even during power loss. Built with heat-resistant PBT material.
