1. An inverter apparatus comprising:
a DC voltage link, an input stage coupled to the DC voltage link and configured to receive DC electric power from a DC power generator for loading the DC voltage link, a DC/AC converter coupled to the DC voltage link and configured to feed AC electric power into a power grid, a bidirectional connection configured to couple a battery to the DC voltage link (6), to load the battery out of the DC voltage link in a first direction, and to load the DC voltage link out of the battery in a second, opposite direction, and a controller configured to operate the DC/AC converter and, dependent on present values of relevant parameters of the battery, to selectively operate the bidirectional connection in the first direction or the second direction, wherein the controller is coupled to an interface configured to receive the present values of the relevant parameters of the battery from a battery monitoring unit associated with the battery, wherein the relevant parameters of the battery issued by the battery monitoring unit and received by the interface include working data related to at least a state of charge of the battery and safety data indicating a safety state of the battery, wherein the controller is configured to consider the working data in operating the bidirectional connection, and wherein the controller is configured to be commanded by the safety data (20) in operating the bidirectional connection. |
