1. An apparatus, comprising:
an enclosure comprising:
a battery configured to output a direct current (DC) power via a first electrical connection;
an inverter having an internal transfer switch, the inverter configured to:
(i) receive the DC power from the battery via the first electrical connection, convert the DC power to a first alternating current (AC) power and output the first AC power to a variable frequency drive via a second electrical connection; and
(ii) receive a second AC power from a transfer switch via a third electrical connection and auctioneer the second AC power to the variable frequency drive via the internal transfer switch and the second electrical connection, wherein the internal transfer switch is distinct from the transfer switch and wherein the receiving and the auctioneering maintains a constant output to the variable frequency drive;
the variable frequency drive configured to:
receive the first AC power and the second AC power from the inverter;
convert the first AC power and the second AC power to a three-phase current; and
output the three-phase current via a fourth electrical connection;
the transfer switch configured to:
receive power from at least two power sources, the at least two power sources including the variable frequency drive; and
output the power via a fifth electrical connection; and
a port coupled to the enclosure, wherein the port includes a plurality of outlets, the port configured to;
receive the power from the transfer switch; and
output the power via the plurality of outlets.
