1. A system, comprising:
a control unit including:
a main distribution box having a plurality of alternating current connections;
a combustion engine electrical generator having an alternating current output coupled to one of the alternating current connection of the main distribution box; and
a first plurality of photovoltaic panels having a first direct current output coupled to a first solar inverter that converts the first direct current output to an alternating current output that is coupled to one of the alternating current connections of the main distribution box; and
a solar unit including:
a second plurality of photovoltaic panels having a second direct current output coupled to a second solar inverter that converts the second direct current output to an alternating current output that is detachably coupled to one of the alternating current connections of the main distribution box using a cable; and
a first rechargeable battery unit coupled to a first battery inverter, wherein the first battery inverter may be controlled to convert alternating current to direct current for charging the first battery unit and to convert direct current discharged from the first rechargeable battery to alternating current, and wherein the first battery inverter is detachably coupled to one of the alternating current connections of the main distribution box using a cable; and
a light unit including:
an array of area lights supported by a mast;
a third plurality of photovoltaic panels having a third direct current output coupled to a third solar inverter that converts the third direct current output to an alternating current output; and
a second rechargeable battery unit coupled to a second battery inverter, wherein the second battery inverter may be controlled to convert alternating current to direct current for charging the second rechargeable battery unit and to convert direct current discharged from the second rechargeable battery to alternating current, and wherein the first battery inverter is coupled to the third solar inverter and the array of area lights and is detachably coupled to one of the alternating current connections of the main distribution box using a cable.
