The present disclosure provides systems and methods for optimizing loading of battery inverters. A method may include determining a required power for a load, the load coupled to a plurality of inverters, the plurality of inverters coupled to a plurality of energy storage units in an energy storage system (ESS); determining a number of the plurality of energy storage units in the ESS needed to provide the required power; establishing a schedule for the determined number of the plurality of energy storage units, wherein the schedule includes a plurality of time periods for power delivery; and sending a first control signal to engage a first grouping of energy storage units for a first time period and a second control signal to engage a second grouping of energy storage units for a second time period of the plurality of time periods.
