efergy e2 Energy Monitor

Affordable and easy-to-install solar array and energy use monitoring!

Efergy’s e2 is a revolutionary wireless power monitor that can be used for both monitoring solar array production, quantifying energy consumption in your home and displaying that information on a wireless display. The e2 is a renewed version of the eLite monitor and has 9 new features. Efergy’s e2 energy monitor allows you to quantify your solar array’s production or your energy use by updating every 10 seconds so you can instantly see the impact of turning a light on or off, using the stove top burner, or your electric clothes dryer. Installation is simple and takes less than 5 minutes.

The e2’s improved memory function allows you to see how much you have used today, yesterday and allows you to review up to 24 months of history. The e2 monitor also displays your daily average so you can see when you are using more electricity than normal and see how your average usage reduces as you change the way you do things. The e2 energy monitor can also be set with 4 different utility tariff settings to let you know when you are consuming a lot during the expensive part of the day!

  • Portable compact display can be placed anywhere in the home up to 70 m range, making monitoring accessible and easy
