The immerSUN monitors the electricity which is about to be exported to the grid and diverts it to the immersion heater. It then automatically directs any excess generated electricity, not used by the house, to the immersion heater in the hot water cylinder.
If the load from the house increases, eg. the washing machine is turned on, the immerSUN will reduce the amount sent to heat water to help you maintain independence from the grid.
