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.

Abstract: A unique electrical system includes a first electrical component and a second electrical component. A conductor electrically couples the first electrical component with the second electrical component. A sensor is constructed to sense an AC power flow in the conductor and output an AC signal proportional to the AC power flow. A band-pass filter is in electrical communication with the sensor and constructed to receive and filter the AC signal and to generate an AC voltage proportional on the AC signal. A controller is in electrical communication with the band-pass filter, and is operative to receive and sample the AC voltage. The controller is configured to execute program instructions to sum sequential AC voltage values received from the band-pass filter over a sample time period, and to determine whether an arc fault has occurred based on the summed AC voltage values.
