1. A modular energy system controllable to supply power to a load, comprising:
three arrays, each array comprising at least two modules electrically connected together to output an AC voltage signal comprising a superposition of output voltages from each of the at least two modules, wherein each of the modules comprises an energy source and a converter;
a charge port configured to conduct a DC charge signal and a single phase AC charge signal; and
routing circuitry connected between the charge port and the three arrays, wherein the routing circuitry is controllable to selectively route the DC charge signal to each of the three arrays when in a DC charge state, wherein the routing circuitry is controllable to selectively route the single phase AC charge signal to each of the three arrays when in an AC charge state, and wherein the routing circuitry comprises at least one switch that conducts the DC charge signal in the DC charge state and the AC charge signal in the AC charge state.
