Claim 8:
9. A hybrid light tower, comprising:
an engine;
a permanent magnet generator configured to be driven by the engine, wherein the generator is configured to produce a DC power;
a battery pack including a plurality of lithium-ion battery cells;
a mast;
a light assembly including a plurality of light emitting diodes, the light assembly coupled to the mast and the light emitting diodes electrically coupled to the battery pack to receive power from the battery pack, the generator, or both the battery pack and the generator; and
a controller in communication with the engine, the battery pack, and the light assembly, the controller being configured to:
receive an available power output from the battery pack;
determine if the available power output is less than a commanded power consumption of the light assembly; and
upon determining that the available power output is less than the commanded power consumption of the light assembly, instruct the engine to increase speed and thereby increase the DC power provided by the generator.
