An inverter for converting DC voltage into AC voltage, in particular a photovoltaic inverter for high power densities, in particular 250 W/dmto 500 W/dmpower densities, has at least one DC input, an AC output, a heat sink, a printed circuit board, a DC disconnector, a DC-DC converter, an intermediate circuit, a DC-AC converter and a housing with a front cover and a basic shell. The electrical components of the DC-DC converter, intermediate circuit and DC-AC converter are combined into subassemblies. At least the DC disconnector and the subassemblies of the DC-DC converter, intermediate circuit and DC-AC converter are directly arranged on the circuit board in a U-shaped manner corresponding to the energy flow direction from DC input to AC output. The circuit board is arranged with the component side facing the base () of the basic housing shell and with the opposite side on the heat sink.

Inverter

For a simple and reliable data communication in an arrangement composed of a plurality of inverters () connected in series and a network monitoring unit () it is provided that the network monitoring unit () superimposes a synchronization pulse () to the network voltage (V) applied to the electrical load (), which synchronization pulse can be detected by the inverters () for temporal synchronization.
