Alternative energy interface, with power control system, multiple source combiner, and islanding

Abstract

This disclosure provides systems, methods, and apparatuses for a power control system device housed in a subpanel, that allows for multiple alternative energy inputs as well as providing an islanding feature, which allows a homeowner to receive alternative energy power when the utility power is lost. For example, in a system that includes an electrical service panel main with a main circuit breaker that is connected directly to a utility electrical source, which may have one or more secondary circuit breakers that back-feeds current from an alternative energy source, there is provided an apparatus that: monitors current from both circuit breakers and prevents excess power from overheating the service panel and/or the wiring to the main circuit breaker; may have multiple spaces for circuit breakers that may be connected to multiple alternative energy sources; and may continue to feed specific loads to the home when utility power is lost and one or more alternative energy sources are available.
