Method and device for using the electrical energy of a device connected to a domestic power grid for generating renewable electrical energy

摘要

The method involves generating renewable electrical energy as an electric current by portion of the photovoltaic system (2) connected to the several household power supply devices (3). The generated electrical energy is supplied to customers (11-14). The difference between renewable electrical energy generated by photovoltaic system and consumed by consumers and electric energy not consumed by consumers is measured. The excess electrical energy is supplied to the water heater (19) to heat water. An independent claim is included for device for implementing the process for generating renewable electricity for household power supply device connected to photovoltaic system and wind turbine for building.
