Systems, apparatuses, and methods for receiving a first magnitude of AC-sourced current at an inverter/charger from an AC bus and receiving a second magnitude of DC-sourced current at the inverter/charger from a DC bus. Then, a third magnitude of current is delivered to a load coupled to the AC bus. Given the dual originating sources of possible current to supply power to the load, the method may determine if the third magnitude of current being delivered to the load is less than the second magnitude of DC-sourced current and then, in response, converting a portion of the first magnitude of AC-sourced current into DC current to charge a DC source. Similarly, the method may determine if the third magnitude of current being delivered to the load is greater than the second magnitude DC-sourced current, and then, in response, inverting the DC-sourced current into an AC current.
