The method involves connecting an inverter (4) to an alternating-current network (3), when direct voltage exceeds minimum voltage for continuation of a connection that is less than or exactly equal to the minimum voltage for attempting connection. The inverter is deactivated, when direct voltage generated by a photovoltaic system (2) drops. The inverter is disconnected from the network, when the direct voltage for the inverter falls below a switch-off maximum voltage that is greater/less than or exactly equal to the minimum voltage for continuation of the connection. An independent claim is also included for a device for connecting a photovoltaic system to an alternating-current network. |
