Essential Info

The eze System WattNode® Modbus Wattmeter is a kilowatt hour (kWh) energy and power meter that offers precision energy and power measurements in a compact package. It enables you to make power and energy measurements within existing electric service panels avoiding the costly installation of subpanels and associated wiring. It is designed for use in demand side management (DSM), sub-metering, and energy monitoring applications. The WattNode uses a half-duplex EIA RS-485 interface and communicate with the eZEio Controller (sold separately) over an RS-485 network. The standard baud rates are 9,600 and 19,200 baud, and rates from 1,200 to 38,400 baud can be configured. The meter uses the industry standard Modbus RTU (binary) communication protocol, allowing up to 127 devices per RS-485 subnet. The WattNode Wattmeter can auto-detect RS-485 polarity on properly biased networks, simplifying installation. It has three power diagnostic LEDs (one per phase) that flash green for positive power, red for negative power, and yellow for low power.

The WattNode Modbus Wattmeter measures the following:
  • True RMS Power - Watts (Phase A, Phase B, Phase C, Sum)
  • Reactive Power - VARs (Phase A, Phase B, Phase C, Sum)
  • Power Factor (Phase A, Phase B, Phase C, Average)
  • True RMS Energy - Watthours (Phase A, Phase B, Phase C, Sum)
  • Reactive Energy - VAR-hours (Sum)
  • AC Frequency
  • RMS Voltage (Phase A, Phase B, Phase C)
  • RMS Current (Phase A, Phase B, Phase C)
  • Demand and Peak Demand
