An energy storage system includes a plurality of batteries coupled in series, a plurality of first isolated DC-DC power converters each having first and second sides, a DC bus coupled to the second sides of the plurality of first isolated DC-DC power converters, and a second isolated DC-DC power converter coupled in parallel with the plurality of first isolated DC-DC power converters. Each of the first sides of the plurality of first isolated DC-DC power converters is coupled to at least one of the batteries. The second isolated DC-DC power converter includes a first side coupled to the plurality of batteries and a second side coupled to the DC bus. The second isolated DC-DC power converter is configured to mitigate a transient load condition on the DC bus.
