Abstract: A controllable main breaker includes a main breaker sized to fit within an existing panel slot of an electrical panel. The main breaker comprises a trigger to open the main breaker in response to a thermal fault or overcurrent event. The controllable main breaker further includes an auxiliary shell sized to fit within at least one adjacent breaker slot. The auxiliary shell includes a controllable actuator that mechanically opens the main breaker.

Abstract: In various embodiments, a process for configuring or commissioning a solar power system includes receiving, at a controller, hardware identifiers of a plurality of power electronics modules to be configured. Each of the plurality of power electronics modules of at least a portion of the plurality of power electronics modules is associated with a corresponding photovoltaic panel. A hub is configured to wirelessly communicate with the plurality of power electronics modules. The controller is physically connected to the hub and communicates with the hub via wiring that also carries power from photovoltaic panels to an inverter. The process includes configuring, by the controller, the plurality of power electronics modules using the received hardware identifiers.

Abstract: In various embodiments, a process for performing metering component testing includes obtaining a configuration associated with at least one metering component installed at a site to be metered and performing a metering component test. The metering component test includes at least one of: detecting phase assignment of the at least one metering component based at least on the configuration, and detecting polarity of the at least one metering component based at least on the configuration. The process includes outputting information associated with the metering component test.

Abstract: The systems and methods herein described isolating a circuit breaker panel for a building from a grid circuit during an event disrupting the grid circuit. In one aspect, a interrupt switch system comprises a housing configured to mate with an electric meter socket on a first side and an electric meter on a second side, the housing comprising power inputs from grid power and power outputs to a circuit breaker panel and an interrupt circuit disposed within the housing and configured to interrupt a flow of electricity from the power inputs to the power outputs.
