Abstract: A hybrid light tower includes an engine, a generator configured to be driven by the engine, a battery pack, a mast, a light assembly having a plurality of lights, and a controller. The generator is configured to produce electrical power. The battery pack is electrically coupled to the generator to receive the electrical power from the generator to charge the battery pack. The light assembly is coupled to the mast and the lights are electrically coupled to the battery pack to receive electrical power from the battery pack. The controller is configured to receive a commanded power load of the light assembly, determine if the commanded power load is greater than the electrical power output by the generator, and in response to determining that the commanded power load is greater than the electrical power output by the generator, instruct the engine to increase speed.

Abstract: A portable heater includes a housing having an air inlet and an air outlet, one or more burners housing within the housing and configured to heat air passing through the housing from the air inlet to the air outlet, and a duct positioned in a storage compartment of the housing. The duct includes a first end coupled to the storage compartment and a second end extendable from the housing when a door of the storage compartment is in an open position.

Abstract: A hybrid light tower includes an engine, a generator configured to be driven by the engine, a battery pack, a mast, and a light assembly including a plurality of light emitting diodes. The generator is configured to produce a first DC power. The battery pack is directly electrically coupled to the generator to receive the first DC power from the generator to charge the battery pack. The light assembly is coupled to the mast and the light emitting diodes electrically coupled to the battery pack to receive a second DC power from the battery pack.

Abstract: A light tower includes a base, an extendible mast coupled to the base, a battery pack supported on the base and including a plurality of lithium-ion battery cells, a light assembly including a plurality of light emitting diodes electrically coupled to the battery pack, a user device configured to receive an input runtime, and a controller in communication with the battery pack, the light assembly, and the user device. The is configured to receive the input runtime from the user device, determine an available power output of the battery pack, and determine a light intensity of the light assembly based on the input runtime and the available power output of the battery pack to ensure the light assembly operates for the input runtime.
