Voltage optimisation controls the voltage received by appliances in your home so you you’re not paying extra for excess electricity. Most household appliances we use work optimally at 220V, as products manufactured for Europe are designed for mainland Europe where the grid is 220V, not the 240V the UK has traditionally maintained.
Grid voltage in the UK can vary between 216V to 253V, with an average grid voltage of 245V, so depending on the exact grid voltage where you live the technology could save you up to 10% on your electricity bills by lowering the voltage to an optimal level. We’ll be able to let you know how much you could save when we check your voltage during your site survey.
Voltage optimisation units from V-Phase could save up to 17% electricity consumption on Fridges and Freezers, normal light bulbs could save 15% and even energy-saving bulbs could save 10%. Energy savings vary by appliance, but if you think you can benefit, investigate getting a unit fitter at the same time as Solar PV to save on installation costs.
