<p>A photovoltaic system has a first photovoltaic generator (11), a second photovoltaic generator (21) and an inverter (31). The photovoltaic system generates electrical energy that can both be supplied to local loads (16, 26) and also can be fed into a public energy supply grid (40). A DC switching element (32) is provided, via which the inverter (31) is selectively connectable on the DC side either to the first or to the second photovoltaic generator (11, 21). The local loads (16, 26) are assigned to two separate consumer circuits, namely a first consumer circuit (15) and a second consumer circuit (25). An AC switching element (33) is provided, via which the inverter (31) is selectively connectable on the AC side either to the first or to the second consumer circuit (15, 25), and in that a control device (34) is provided, via which the DC switching element (32) and the AC switching element (33) are actuated in coordinated fashion such that a connection of the inverter (31) to the first consumer circuit (15) goes along with a connection of the inverter (31) to the first photovoltaic generator (11), and a connection of the inverter (31) to the second consumer circuit (25) goes along with a connection of the inverter (31) to the second photovoltaic generator (21). The system allows more than one household to share the use of an inverter to benefit from feed-in compensation schemes.</p> |
