Abstract
An inverter apparatus includes an input stage receiving DC electric power from a DC power generator for loading a DC voltage link, a DC/AC converter connected to the DC voltage link and feeding AC electric power into a power grid. The apparatus further includes a bidirectional connection for loading a battery out of the DC voltage link and for loading the DC voltage link out of the battery, and a controller operating the DC/AC converter and the bidirectional connection. The controller receives present values of relevant parameters of the battery including working data at least related to a state of charge and safety data indicating a safety state of the battery from a battery monitoring unit. The controller, in operating the bidirectional connection, considers the working data and is commanded by the safety data.
