Abstract: Apparatuses, systems, and methods are presented for energy storage. A plurality of input connectors are configured to receive input power from one or more power sources. A plurality of input power converters are coupled to the input connectors, and are configured to convert the input power to direct current (DC) power for storage. A controller is configured to control power flow through the input power converters on a per-converter basis so that separate converters are separately controlled. One or more output power converters are configured to convert stored DC power to output power for use by one or more loads. The controller is configured to control power flow through the one or more output power converters. One or more output connectors are configured to transfer the output power to the one or more loads.
