Efergy Engage Hub Online Energy Monitor - Solar
The Efergy Engage Hub for Solar allows you to track your energy usage and solar power production from your smart phone, tablet or computer.
Don't have Solar Panels? See the regular Efergy Engage Hub Kit.
Our price includes everything you need:
- The Hub - A small wireless gateway that plugs into your internet router.
- Two Transmitters - These go inside your meter box. One is for household consumption, the other for solar power production.
- Sensor Clamps - These plug into the transmitters and measure the power. We'll send you the required number of clamps depending on the model you choose (single or three phase, etc).
- Free Software & Apps - Free access to the efergy engage online platform as well as apps for iPhone, Android and iPad.

How to Install - Solar Energy Monitor
It is typically a quick job for an electrician to fit the sensor clamps at the appropriate positions at your meter board. The following simplified diagram shows how the clamps should be installed to ensure the readings are correct.
- Position 1 = Household Power Consumption
- Position 2 = Solar Power Production
Please note that wireless energy monitors cannot sense the direction of current flow, only the total amount going through the cable. For this reason you need to ensure the clamps are installed correctly (as above) on 'household consumption only' and 'solar production only' cables, otherwise the reported numbers may not make sense.
Solar Energy Monitor - Example Installation
In some cases, a small amount of re-wiring of the fuse box is required to enable the correct installation outcome as indicated above.
* IMPORTANT * Installation works of this nature must be carried out by a licensed electrician.
In the following picture you can see a typical single phase fuse box with the cover taken off. The solar PV breaker is on the far right. It feeds current into the power system via the long red wire that leads to the main breaker switch on the far left.
The following image is a close up of the main breaker switch. The mains power from the grid enters at the bottom, at the top (pictured) are the various connections to household loads. One of these wires is the solar power, the others lead off to various household circuits via other breakers. The top of the main breaker is being used as a junction, making it tricky to separate solar from household power.
For the current sensor to work properly, what is needed is a single wire that has all of the household loads flowing through it. This wire should be completely separate from the current flowing from the solar PV system.
In this instance, an electrician can move some junction points to other breakers. This should leave you with just two wires connected to the load side of the main breaker: "solar" and “everything else.”
The following picture shows the same board after some re-wiring, including the current sensor clamp positioned around the "everything else" cable.
Frequently Asked Questions
How often do the readings update?
The main 'Real Time Usage' power reading updates every 6 seconds. This can also be reduced to once every 12 or 18 seconds to conserve the battery life of the transmitter.
How detailed is the usage information?
The usage graphs are very detailed, with the main 'Energy Demand' graph showing usage at a minute-to-minute level. You can even scroll backwards through time to view data from previous days.
Using the 'History Usage' chart you can also scroll back and see cumulative totals by hour, day, month and year. Here is an example:
Can I view a live preview of the software?
Yes - you can view a live preview of the software here: Efergy Engage Dashboard Demo.
Please Note: your actual login will display in $ not £ like on the demo site.
How much does the software cost?
The software is free. In other words, the ongoing software cost is included in the upfront cost of the hardware (price shown on this page).
Can I download the data?
Yes - you can download the data in CSV format for use in other applications (such as Microsoft Excel).
Can I see individual phase data when using a 3 phase transmitter?
No - the three phase transmitter shows a cumulative total of the three phases, not three individual readings.
If you want to see individual phase readings you would need to have one transmitter and clamp for each phase.
How many extra transmitters can I add to the hub?
The efergy engage hub can accept data from up to 5 transmitters in total. This means you can add up to 3 additonal transmitters (as the solar kit ships with 2 transmitters included). See our energy monitors section for extra clamps and transmitters.
Can I add multiple electricity tariffs into the software?
No - the software does not currently accommodate multiple tariffs. But you can download the data as a csv and perform your own detailed cost analysis if/when required.
What other products are available?
If you do not have solar power, or do wish to monitor your solar power specifically, please see our efergy engage hub - regular package.
If your primary intention is to sub-meter electricity usage for the purposes of on-billing we would recommend one our our electrical sub-meters found in the power meters section. You can also find individual appliance monitors in the power meters section.
