Optiplug intelligent socket
for use with Wattson Solar Plus or Optimmersion

Automatic solution
Optiplug turns appliances on when they can run for free if there is enough surplus electricity from your Solar PV and off if there isn’t – making use of your free generated electricity automatically even when you are out.
Easy add-on
Optiplug is easy to add on to any Wattson system measuring generation to start and with Optimmersion and Optismart Hot Water to continue to make use of surplus power.

What people are saying about Optiplug

“Initially, I found it very easy to set up, it is paired with Wattson’s transmitter and currently calibrated to a small Oil filled heater which was set to a 600Wh setting. I am now using 600Wh that before, would have been wasted without the Optiplug. The instructions were easy and clear to follow, without any problems.”

David Jones, Daventry

“So far, my initial reaction is great gadget, does exactly what it says on the tin. I had no problems linking it to the Wattson transmitter or configuring the unit to the load: tumble dryer on low power. The device is doing exactly what it is programmed to do, turning the dryer on when I have 1.8kw available electricity.”

Tony Hall, Lancashire

“The sun is great, I am really pleased with the Optiplug it’s working well, I must admit I was worried how it would handle a series of clouds moving over the sun but you seem to have the reaction time just right. I am using Optiplug to control a low power immersion heater, now I can go out and come back to lots of lovely hot water. I am happy with the Optiplug, it was well worth waiting for.”

Derek Weaver, Hampshire

“I am really pleased with the Optiplug, I use the device to control the battery charger on my electric boat, it works very well and enables me to state to my friends that my boat is solar powered even though the actual boat has no solar panels! www.electric-launch.co.uk”

Product information

Optiplug is an intelligent socket which switches on your appliances when you have spare electricity.

The smart socket learns and understands how much electricity is used by the appliances that are plugged into it.

Optiplug then only switches on when enough electricity is available for those appliances, switching off when electricity is no longer free.

When more than one Optiplugs are installed, the built-in intelligence prioritises your appliances by power to minimise the amount of switching that takes place. To ensure maximum efficiency of your surplus power, higher power appliances take priority over lower powered ones: a 2kW appliance would switch on first and switch off last and a 300W appliance would come on last and switch off first.

The smart activity optimises your use of your own excess generated electricity.

Works with existing Wattson Solar Plus, Optimmersion®, Optismart Hot Water and original Wattson systems that measure renewable energy.

How it works

Optiplug measures how much electricity the appliance plugged into it uses, and when Wattson tells it there is enough surplus energy for the appliance to run for free, Optiplug will switch on. It will switch off as soon as there is not enough free electricity, for example when you turn something else on or when the sun goes down.

Optiplug uses Wattson sensors to constantly measure the power being generated by Solar PV and also power in use in the home.

The system knows not to keep things switching on and off.

Optiplug can listen to up to 4 transmitters, just like the Wattson Solar Plus.

Multiple Optiplugs can be installed in each home; higher power appliances will turn on with priority over lower power appliances. Optiplugs have manual override so appliances can still be used when there is not enough sun.

There is a manual override button should you wish to keep the item on.

There is a time delay on switching off and switching on, so that multiple Optiplugs don’t compete for the same amount of spare energy.

Check out our installation videos here.

Can be used with any device that uses/charges with electricity, that doesn’t require a manual switch on (unlike most washing machines) and doesn’t mind being interrupted.
