摘要

A switching layout contains a generator (1) designed as a photovoltaic module connected to DC or AC voltage mains (4) by a first transformer (2) and a first switch (3) operated as a DC or AC converter. A battery (5) is connected to the mains (4) through intermediate switching with a second transformer (6) corresponding the first transformer. A consumer (8) is also connected to the mains by a second switch (7).
