Abstract: The present invention relates to a separator, a separator combined or integrated with a collator and a method of such separators, in order to provide segments of collated fasteners. Segments of collated fasteners are mainly used by builders, who are assembling e.g. wooden structures or for mounting purposes, to engage the fasteners by shooting or screwing the fastener into a structure with a pneumatically operated tool such as a nail gun.

Abstract: An electrical power supply apparatus has at least one electrical load connection to which an electrical load can be connected. A first electrical power supply connection can be connected to a mains supply network. A second electrical power supply connection is connected to an autonomous electrical power supply, such as a photovoltaic system. A switching apparatus switches the connection of the at least one electrical load connection to the first electrical power supply connection in mains operation or to the second electrical power supply connection in island operation. In order to improve the energy management during island operation, the at least one electrical load connection has at least one associated evaluation and control apparatus, which identifies the island operation of the electrical power supply apparatus and switches the at least one electrical load connection on or off, at least during island operation, as a function of preset criteria.

Abstract: A photovoltaic system includes a solar module having at least one solar cell. In order to reduce the power loss of the solar module when a solar module is in shade or is defective, a semiconductor switching element is connected in parallel with the solar module and drive electronics block the semiconductor switching element when the solar module is generating power and otherwise switch the semiconductor switching element to low impedance in order to bridge the solar module.

Abstract: A mount module for an inverter includes a housing element with a recess being open to the front face, for holding a single inverter. The upper face and the lower face of the housing element are complementary to one another, and/or the right side and the left side of the housing element are complementary to one another, and/or the rear face of the housing element is complementary to itself. The respective side or sides and face or faces of the housing element each have at least one connection device. A relatively large number of the mount modules can be disposed one above the other, alongside one another, and/or with their rear faces against one another and can be connected to one another in order, for example, to form a central inverter unit for large photovoltaic installations.
