Summary: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.
