Circuit arrangement for use as emergency power supply, has bidirectional controller that is connected between power source and inverter, so that electrical energy of energy source is stored in memory and is fed into public grid

摘要

The circuit arrangement has regenerative power source (1) for generating electrical energy and an electrical connection of power source with an inverter (3) for feeding electrical energy into public grid. A bidirectional controller (5) attached to storage unit (6) is connected between power source and inverter, so that the electrical energy of energy source is stored in storage unit and is fed into public grid (4). An independent claim is included for process for intermediate storage of electric energy from renewable energy source.
