Abstract: A control device for a battery storage device, which is equipped with components of the electronics system, e.g. battery management system and current measurement shunt, and with components of the electromechanical system, e.g. in the form of relays, fuses, bus bars, and plug connectors, and is accommodated in a closed housing. In order to create a control device in which a predetermined service life can be reliably achieved even without an oversizing of components, it is proposed for the closed housing to be embodied to form a free and/or forced convection, it being possible for the convection to balance out temperature differences inside the housing and throughout the control device.

This is achieved in that the battery storage device comprises the following: a battery storage housing that encloses an interior in which one or more battery modules are received or can be received; and one or more temperature-controlling elements through which a temperature-controlling medium can flow in order to control the temperature of one or more battery modules which are received or can be received in the interior of the battery storage housing, wherein the one or more temperature-controlling elements comprise a temperature-controlling medium inflow connection and a temperature-controlling medium discharge connection which are arranged outside of the interior of the battery storage housing, and the one or more temperature-controlling elements are produced by roll bonding in particular.

Abstract: The invention relates to a device and to a method for monitoring a decentralized power generation plant for feeding into a three-phase network in order to prevent undesired island network operation, wherein the power generation plant has an inverter, which produces three alternating currents phase-shifted from each other from an input-side direct voltage, in particular of a photovoltaic generator, which alternating currents are fed into the network. The basis of the monitoring method is that the target power value for a designated phase of the network alternating voltage is changed, e.g. reduced, by a predetermined first amount for a predetermined time period while the target power values for the other two phases are changed in the opposite direction, e.g. increased, by a predetermined second and/or third amount. The sum of the second and third amounts equals the first amount.

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.

Abstract: A photovoltaic system includes a first and a second photovoltaic generator (9, 11) which delivers electric energy, an inverter (4) which can be coupled to the PV-generators (9, 11) for converting electric energy of the PV generators (9, 11) to output AC energy, and a switchable coupling arrangement (3) for coupling the PV generators (9, 11) to each other and to the inverter (4). The coupling arrangement (3) is arranged functionally between the PV generators (9, 11) and the inverter (4) and designed to connect the PV generators selectively either in a series circuit arrangement or a parallel circuit arrangement to the inverter (4). The PV system (1) can therefore expediently be operated with an intermediate circuit voltage which is higher than the maximum voltage of one PV generator for achieving improved efficiency whereas it can be switched to a lower intermediate circuit voltage when necessary, for example, in case of a ground connection fault, to maintain predetermined voltage limits.
