Abstract: A multi-circuit direct current monitor consists of a plurality of Hall Effect current sensors mounted on a printed circuit board oriented to sense the direct current (DC) flow from power generating devices such as solar arrays, output from the Hall Effect sensors connected to an analog to digital (A/D) converter which in turn is connected to a microprocessor. The multi-circuit direct current monitor continuously monitors instantaneous and average current values for each circuit as well as total instantaneous current and average current for all active circuits. The multi-circuit direct current monitor provides continuous communications via Modbus RTU as well as providing alarm outputs if one or more circuits deviates from the average output by a percentage greater than the user specified threshold for a user-defined period of time to detect failed or underperforming power output devices.

Abstract: An electrical receptacle is disclosed. The electrical receptacle includes a housing and at least one socket at least partially disposed within the housing and having at least a pair of entry ports. The at least one socket is controllable by a radio frequency signal. The electrical receptacle also includes an antenna at least partially disposed within the housing configured to at least receive the radio frequency signal used to control the at least one socket. The electrical receptacle further includes at least one tamper resistant device at least partially disposed within the housing. The at least one tamper resistant device is configured to block the entry ports unless a mating electrical plug is inserted into the at least one socket.
