A serial acquisition of multiple power sources via one or more multiplexers which is circulated in many corridors of a multi-port system with a resonant engine. A controller manages multiplexer/switches connecting a first plurality of DC power sources and an auxiliary DC power source to a circulator. A multiplexer/switch revolves each source of power to inverters for DC-AC conversion. Reciprocity of power sharing and management of signal routing between input power sources can be performed to maintain discrete operation between the input/output power sources and individual power inverters for precise load power delivery. Regenerative power from a motor load can be directed to “recharge” an input power source. The resonant engine applied to each power source provides a constant conduit of energy during off-operation/cycles.
