Solar Powered Security Light Tower – Kemp, Texas (Solar Thermal Magazine ) May, 2014
The SPLT-1.8K-800A-30-4X160W-LED-MS fromLarson Electronics is a 1.8KW solar generator system that replenishes 800 amp hours of usable battery capacity per day. This solar security system is equipped with four 160 watt LED light heads atop a 30’ collapsible, pneumatic mast and is equipped with a motion sensor for instant illumination whenever motion within the secured area is detected. This unit is comprised of six 30-watt solar panels, generating a total maximum output of 1.8 KW. The panels are mounted to a rotating axis assembly.
The panels can be rotated until they face inwards, which protects the panels during transport. When deployed, the panels are rotated until they face upwards. As part of the deployment, operators will set the four outriggers into position by pulling them out and pinning them into position.
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 an 800 amp battery bank. This 24 volt battery system is comprised of eight 6 volt batteries tied together in series and parallel. The battery bank cannot be drained below 50% without destroying the batteries.
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 light 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’ in height via the use of 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.
“Our new solar powered pneumatic light mast is fully solar and requires no fuel to operate,” Rob Bresnahan with Larsonelectronics.com said.
In the event that there is an issue with the solar trailer, the operator can simply remove the SD card from the Mate 3 and send it in for analysis.
