Abstract: In one embodiment, an energy management module having a form factor adapted to fit within one or more slots of a load center or panelboard of a structure is provided. The energy management module includes a housing configured to fit within the one or more slots of the load center or panelboard. It has a plurality of current sensor connectors configured to connect to current sensors that measure current flowing through breakers of the load center or panelboard to circuits within the structure. One or more power measurement DSPs are provided to measure power consumption of the circuits. It further has a microcontroller unit with a wireless network interface configured to communicate the power consumption measurements to a host controller or cloud services that provide the power consumption measurements for display in an energy management user interface.

Abstract: A technique enables microgrid switchover using zero cross detection. A flexible load management system includes a virtual critical load panel (vCLP) that utilizes circuit breakers in combination with companion modules configured to sense power provided to one or more loads to identify zero-crossings. When a preconfigured number of consecutive, missed zero-crossings is detected, the companion module is alerted as to potential main power loss and transitions to a virtual critical load (vCL) mode for load adjustment prior to operation under local power. Upon detection of main power loss, the companion module is configured for load activation (or deactivation) via states of one or more vCL bits that configure each load for either ON or OFF state when operating under local power.
