Abstract: The present invention provides a system and method for monitoring or controlling a small to medium solar or wind power production system to provide improved safety and reliability of the system, wherein the monitoring or control system provides one or more of firmware, hardware, software logic, or monitoring circuits in a system designed to increase its safety or to improve its reliability that includes: a circuit combined with one or more of hardware or software logic that provide a means for monitoring said power production system to check for over load or under load measurements at a plurality of power switches of said power production system.

Abstract: The present invention provides long-lasting, reusable wire electrical cable connectors that can be quickly connected and disconnected to accommodate the safe connection or termination of a plurality of wires upon reversibly joining said wire electrical cable connectors, wherein each reusable wire electrical cable connector comprises at least two main members as a connector pair, a male connector member and a female connector member. In a second embodiment type, the invention provides for terminating connector pairs where the male for female connector member is adapted to terminate wiring of a single cable rather than to connect two different cable pairs of the wiring. The invention further provides optional tools for quick connecting and disconnecting of the two connector members of a connector pair of either of the two embodiment types to efficiently snap apart the two connector members for repair or maintenance.

Abstract: The present invention provides a system and method for individual or plural detection of the presence or absence of at least one installed solar panels whether or not the individual solar panel or the plurality of solar panel(s) operates to produce power during the detection process and whether or not the detection is conducted during the day or night, wherein the presence or absence of an individual solar panel or of a plurality of solar panels producing power during detecting comprises detecting presence or absence of one or more solar panels by an associated system that measures power output, and wherein during the detecting process insufficient voltage is produced for the associated system to measure power output. In addition, the present invention provides a means to detect a fire or arcing that may damage a power system, and can provide notification of the need for servicing the power system.
