Efergy e2 Wireless Single 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

Details

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.

Fantastic product and even more!Review by Jan

I use this daily to size a PV system I want to install. The system works really well and the surprise to it all was that it also create an Excel spreadsheet with every report from where you can do just about anything with the hourly data that is being logged.
Really happy with my purchase and will recommend it (with the three point plug system) to anyone. I am sure you can save a lot of electricity already, without anything else. I know, I am saving already and would have paid for these two devices in few months from my savings. (Posted on 10/12/2014)

I have purchase the electricity monitor from you.
This is giving me a more accurate reading than the municipality.

I am looking to build on a granny flat sometime in the future, and would like to go green with it.
I’ll be in contact with you. (Posted on 11/09/2013)

This little gadget does exactly what it says. It is easy to set up and use.
After installing it and making a few changes to my electricity usage I saved the purchase price in my electricity bill in one month.
It is very interesting to see when and where your electricity goes.

Eye-opener!Review by Alex
I have been interested in Solar power for a while now, and have not yet been able to really get my head around what it would cost and what it would save. After reading "Solar Power for Dummies" which basically concludes that it's more about energy conservation than solar generation - I splashed out and bought this as the first bit of my investment towards sustainable and affordable power.

What an eye-opener! After initially setup it was VERY novel to turn on and off every single appliance in our home to see how much it was costing per hour, and after we eventually got round to changing the timing on our pool pump and geyser to save R x per month, the novelty wore off a bit.

Then a month later I downloaded the info and discovered that the new peak periods happened to be on the days the domestics were here - using the washing machine and tumble drier (which was meant for emergencies in winter only!) all the time - its amazing how the downloaded averages point out different info!

So it cost R 1 000, and didn't save anything directly. But it is the tool by which we assess every bit of power that we use and waste (our "spare" fridge freezer in the garage is being sold immediately!). Is it worth it? Yes, definitely.

What you can't measure, you can't manage! I highly recommend one of these products. (Posted on 18/04/2010)
