Efergy Elite - How to install


In most cases the sensor clamp(s) can be fitted at the front of your meter board. It's a quick (5 minute) job for an electrician to fit them behind the board if necessary.

The following video is a simplified depiction of how installation works in the UK. In Australia & NZ our meter boards look quite different to this, but you can see the key components and how the system works in general:

Frequently Asked Questions

How much data does it store?

The Efergy Elite stores data for 12 months. Using the history plus backwards and forwards buttons you can scroll through the last 7 days daily history, the last four weeks weekly history, and the last 12 months monthly history.

Can I place the sensor clamp around the lead to a plug-in appliance such as a portable air conditioner?

No - Wireless energy monitors do not work on regular power leads like an extension cord. This is because they need to clamp around the active cable only at your meter board. You might like to check out our range of 'plug-in power meters' to measure individual appliances such as portable air conditioners.
