    Abstract: Embodiments disclose solar energy generation systems with automatic smart transfer switches. An energy generation system, including an energy generation device, an energy generation inverter coupled to the energy generation device and configured to convert direct current (DC) power from the energy generation device to alternating current (AC) power, a battery pack, a storage inverter coupled to the battery pack, where the storage inverter is configured to convert DC power from the battery pack to AC power and to convert AC power into DC power for storing energy into the battery pack, and a smart main electrical panel coupled to receive AC power from at least one of the energy generation inverter, the storage inverter, and a utility grid, where the smart main electrical panel includes one or more motorized circuit breakers configured to be remotely controlled to manage the power flow to one or more loads.

    Abstract: Embodiments disclose solar energy generation systems with automatic smart transfer switches. An energy generation system includes an array of PV modules, a PV inverter coupled to the array of PV modules, and a battery pack configured to store DC power from the PV modules and output the stored DC power. The energy generation system can further include a storage inverter/hybrid inverter PCS coupled to the battery pack, and an automatic smart transfer switch configured to select between an AC grid and the storage inverter/hybrid inverter PCS for outputting to a main electrical panel, where the automatic smart transfer switch is configured so that in a first position, the AC grid is coupled to the main electrical panel, and in a second position, both the storage inverter is coupled to the main electrical panel.

    Abstract: Embodiments of the present disclosure describe an energy generation system including a rapid shutdown mechanism configured to prevent a flow of power from a photovoltaic (PV) array when activated, a battery pack comprising one or more power storage devices, and an inverter coupled to the rapid shutdown mechanism and the battery pack. The inverter includes anti-islanding relays configured to electrically disconnect the inverter from a utility grid when activated transfer relays configured to electrically disconnect the inverter from a load when activated, and a detection and initiation circuit coupled to the rapid shutdown mechanism, battery pack, anti-islanding relays, and transfer relays, where the detection and initiation circuit is configured to detect a triggering event and to activate the rapid shutdown mechanism, disable the battery pack, activate the anti-islanding relays, and activate the transfer relays in response to the detection of the triggering event.
