EG4030 by eGauge


The eGauge EG4030 is a 30 channel energy meter with 0.5% revenue grade accuracy and measures residential or commercial circuit panels, up to 3-phase 277/480VAC and 6900A

  • This powerful combination of an energy meter, data logger, and a web server lets you measure, store and retrieve data directly from the device or from a remote location
  • Not only does it calculate power (V, A, VAr, kWh, etc), but also data from optional sensors that assess flow rate, temperature, wind speed, and more
  • Modbus RTU and BACnet MS/TP Require a USB485 converter
  • You can view historical and live data for up to 30 years with the unit’s convenient user interface (UI)
  • The UI can be accessed on a local network or via the internet from a computer, tablet, or smartphone
  • Once connected, you have access to real-time values, long-term reports, an interactive graphical interface, and many other tools
  • The best part is that you pay nothing for the user interface because you retrieve data directly from your own eGauge hardware, not a cloud or 3rd party host
  • EG4030 – 64E (eGauge sku)
