The energy monitor showing electricity generation, usage and net usage; Wattson Solar Plus energy monitor maximises returns on your Solar PV by giving you the green light to use your free electricity.
- Measures and displays both electricity generation and usage in the home or office.
- Glows green when more electricity is generated than used, showing when to use your free electricity.
- Inverter independent, compatible with all inverter brands.
- Easifit option to remove the need for a Henley Block or junction box.
- Works with all solar, wind, hydroelectric 230 VAC, single and three phase generation systems.
The Wattson Solar Plus energy monitor allows you to see how much power you are generating, and how much you are using, on the same portable display.
The display shows electricity being generated and used in your home in real time, in cost, watts or kg carbon. Choose your preferred display from a selection of pre-set modes, in numbers and/or colours, for better visibility of your daily electrical activity.
Wattson Solar Plus alerts you when you are generating more power than you are using by immediately glowing green. Being aware of excess generation allows you to maximise the returns on your PV system by understanding when to use your free electricity.[/vc_column_text][vc_column_text]
Wattson Solar Plus uses sensors that simply clip around the outside of electricity cables to get its power data. The data is then sent wirelessly from the transmitter to the display.
It works with 210V-240V single phase or 400V-460V three phase electricity supplies and uses flexible tariff structures to suit most pricing plans and feed-in-tariffs.
To self-fit the sensors, there needs to be access to either the live or neutral wire (single-core wires); if they are contained within a single big cable either side of the fusebox (consumer unit) then the sensors should be fitted professionally by a Solar Installer.
With the range of Wattson accessories, it is simple to: measure three phase supply, three phase generation, install Wattson Solar Plus in more complex environments as well as boost its functionality. Accessories are available from your usual Wattson supplier.
The two most common site environments are shown in the diagrams below.
Wattson Solar Plus is recommended for PV installations that include a Henley Block or junction box. Wattson Solar Plus with Easifit is recommended for all other installations.[/vc_column_text][/vc_column][vc_column width=”1/3″]
Wattson has a single buttonto switch between display modes:
- Grid: how much power is being imported from (+ve) or exported to (-ve) the grid
- Usage: how much power is being used in real time
- Solar: how much power is being generated
- Total Energy Generated: a counter showing how much energy has been generated in kWh, money earned and carbon saved.
- Colours only: current usage displayed using Wattson colour key
- Night mode: reduces the number of lights that are on, reducing the amount of energy the display uses
- Clock: time together with power in watts displayed.

The display’s internal memory can hold up to 28 days’ worth of measurements. Software is available on our website to export, view and analyse generation and usage activity over long periods of time. Simply plug the device into a computer using the USB cable included.
As utility companies have decided not to pay hundreds of pounds per customer to install export meters, almost everyone gets paid as if they use
50% of the energy they generate and export 50% of it. That means homeowners get paid the same regardless of how much of their own generated
energy is actually used.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/1″][vc_column_text]
A range of accessories is offered for more flexible and convenient Wattson Solar Plus installations.
For installations without a Henley Block / junction box, it is required for a correct usage reading on Wattson.
3 Phase Generation
All you need in order to measure three phase generation. Available with or without Easifit.
50 Amp Sensor Clips
Additional CT clips for three phase installations. Cable length is 0.75m.
3m Extension Cable
Three metre extension cables for when the sensor and transmitter are some distance apart.
TX for Wattson
Additional standard transmitter for Wattson. Ideal for PV systems with extra consumer units and sub-circuits.
A more precise sensor and transmitter to provide near meter level accuracy for the generation reading. Can measure up to three phases of usage with additional 50 Amp Sensor Clips.
Additional display for those who wish to show their electricity generation and usage in two or more places.[/vc_column_text][/vc_column][/vc_row]
