The Larson Electronics SPLT-1.5K-750A-30-4XWP120-LED 1.5KW solar-powered light tower is a generator system that replenishes 363 amp hours of usable battery capacity per day. This solar system is equipped with four 120 watt LED light heads mounted to a 30 foot collapsible pneumatic mast and is equipped with a dusk to dawn sensor. The unit is comprised of six 265 watt poly-crystalline solar panels, generating a total maximum output of 1,590 watts. The panels are mounted to a rotating axis assembly. They can be rotated until they face inwards for transporting and rotated upward when deploying.
In this 24 volt system, each panel is terminated with a fused combiner box with a single lever action cut-off switch. With the switch set to the "on" position, the combiner box passes power to the 80 amp capacity Outback Extreme charge controller. The charge controller charges a 750 amp battery bank. This 24 volt battery system is comprised of 12 volt 8D deep cycle acid glass mat batteries tied together in series. The batteries are spaced apart, strapped to the battery tray and covered with a protective shield.
The trailer itself houses a built in wire raceway that brings power from the component control center and batteries to the light mast. At the base of the mast there is an access panel for making connections from the power source to the cabling within the pneumatic mast. The pneumatic mast reaches 30 feet in height with a low voltage air compressor located in the job box. The compressor is equipped with a pressure switch that maintains the pressure within the mast. When it is time to take the mast down for transport, the operator simply releases the pressure switch and the mast will slowly release pressure and lower to its full collapsed height of 8.25 feet. As part of deployment, operators will set four outriggers into position by pulling them out and pinning them into position. Four 2,000 lbs hand crank leveling jacks are used for leveling.
