Abstract: Technologies for providing DC arc protection in a DC socket include an electromagnet positioned in the DC socket configured to produce a magnetic field. The electromagnet is positioned to be adjacent to a contact region between one or more supply terminals of a DC socket and one or more prongs of a DC plug. As the DC plug is disconnected from the DC socket, a DC arc might form between one or more of the supply terminals and one or more of the prongs. The magnetic field produced by the electromagnet reduces the energy of the DC arc and reduces the time duration of the DC arc.

Abstract: A solar energy field having one or more solar energy assemblies is provided. The solar energy assemblies can each have a DC-DC converter which when used with a central converter maintains line voltage between the two below a regulatory threshold such as 80 Volts. The central converter can be a DC-AC converter or a DC-DC converter. Each of the DC-DC converters have or are coupled with an MPPT controller, and in some forms the DC-DC converters can include smart meter devices. Plug and play devices can be used between the DC-DC converters and the central converter. The central converter can provide power to an AC or DC grid within a dwelling such as a house.
