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 or 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 or single phase AC charge signal to each of the three arrays, and wherein the routing circuitry comprises a plurality of solid state relay (SSR) circuits each comprising at least one transistor, wherein the routing circuitry comprises a first port configured to couple with a DC+ charge signal or a single phase AC line charge signal, a second port configured to couple with a DC− charge signal or a single phase AC neutral signal, a third port coupled with a first array, a fourth port coupled with a second array, and a fifth port coupled with a third array, and the routing circuitry comprises:
a first SSR circuit coupled between the first port and the third port;
a second SSR circuit coupled between the first port and the fourth port;
a third SSR circuit coupled between the fourth port and the second port; and
a fourth SSR circuit coupled between the fifth port and the second port.
