Solar iBoost+

The Solar iBoost+ is the UK’s best selling PV immersion controller and preferred by most solar installers; it saves you money by cutting the cost of water heating and reduces the use of your home’s boiler.

If you have invested in Solar PV for your home then you will already be aware that there are periods of “export,” when you can’t consume all the energy being generated by the array. This energy normally flows back to the grid seamlessly so you may not even be aware of it. If your home has hot water storage with an immersion heater then Solar iBoost+ can be installed and start saving you more money on heating bills in less than 1 hour! Solar iBoost’s built in display means that you can watch your savings grow, simply press the display button to see Saved Today, Saved Yesterday, Saved 7 Days, Saved 28 Days and Total Saved readings.
