Efergy e2 Wireless 3 Phase Electricity Monitor

The efergy e2 electricity monitor is simple to install and use. The sensor wirelessly sends information about the amount of electricity you are using to the display monitor. The monitor converts this into kilowatt-hours, the standard unit which the electricity company uses to charge you. This shows how much you are using in the same units that are on your bill. Input the amount your energy company charges you for each kilowatt-hour and you can see how much you are spending in electricity instantly. Make instant changes to save money, energy and the environment.

Product Description


Micro - Generation
• Our monitors can be used to monitor micro-generation but do not provide net metering information. Our sensor will read the current going through your feed cable but will not ascertain the direction of the current. This means that at night, for example, if your inverter is using some electricity the monitor will show this and add it to the generation values.

Simple and it worksReview by Marius Fourie
I have probably imported, bought and tried every meter up to R10 000.00 on the market. This one is simple convenient, and it works. If you want to measure phase angles or 3 phases separately, go more fancy equipment, but for simple consumption patterns, this is the unit to use. (Posted on 08/11/2013)
