Abstract: An inverter system (1) for a photovoltaic solar installation for generating an AC voltage from a DC voltage of a solar generator (2) is provided which includes an additional energy storage device (38) which is arranged in an energy transfer path that can be activated when needed. A control arrangement (31, 39) for monitoring and controlling the operation of the inverter system (1) is designed to detect short-term energy peaks of the insolation at the solar generator and, upon a presence of insolation peaks, to activate the energy transfer path (36) in order to cause a transfer of energy from the solar generator (2) to the energy storage device (38). Also a method for the operation of an inverter system for a photovoltaic solar installation for the utilization of insolation peaks at the solar generator is disclosed.

Abstract: A photovoltaic system for converting a DC voltage from a photovoltaic generator into an AC voltage, includes a transformerless power inverter which comprises high-frequency-clocked switching units, the DC voltage input of which is connected to the photovoltaic generator, and the AC voltage output of which is connected to a series circuit consisting of a bias generating device and an inductive HF decoupling device. The bias generating device is used to apply a bias potential to the AC voltage output of the power inverter, said bias potential also indirectly influencing the voltage potential at the DC voltage input of the power inverter. The inductive HF decoupling device is used for the HF decoupling of the AC voltage side from the DC voltage side of the power inverter in order to prevent capacitive discharge currents to the photovoltaic generator due to the use of the bias generating device.
