Solar Immersion Switch – How It Works


Do you know that up to 70% of the energy produced is exported back to the grid as it may exceed your immediate needs. The ImmerSUN devise uses this electricity by using your Solar PV/Wind Turbine system as an alternative to a Solar Thermal system.

Unless you have an export meter fitted, your electricity company assumes that 50% of the electricity you generate from your panels is sent back to the grid. With the immerSUN unit you could you use all of this exported electricity and still get paid for the 50% from the electricity company.

The immerSUN is designed to work in properties which have a hot water cylinder with either an immersion heater installed or the facility to have one installed.As soon as your PV system starts to export power to the grid the immerSUN unit redirects any excess generated electricity to the immersion heater in the hot water cylinder. The immerSUN works with all Solar PV systems and immersion heaters.

If the load in your house changes, e.g. you put the dishwasher or washing machine on, the immerSUN will recognise this and reduce the amount of power sent to the immersion, therefore maintaining the independence from the grid. Over-clouding and shading will also alter the immersion feed.
