Solar Light Tower for Sale: Sunray LTS-80 (500W / 660 Ahr)

The Sunray LTS-80 by National Signal is a portable solar light tower built for heavy-use field deployments across construction, mining, utility, and event applications. A 500W solar array charges a 660 Ahr AGM battery bank during daylight. Four 80W LED fixtures draw from that stored power overnight across three selectable brightness levels. There is no diesel engine, no alternator, and no fuel requirement.

The LTS-80 trailer and mast are built extra heavy for continuous outdoor deployment on uneven and demanding terrain. The unit's 2,000 lb. operating weight and compact footprint make it a practical option for rental fleets and multi-unit deployments where transport efficiency matters.

How the LTS-80 Solar Charging System Works

The LTS-80 operates on a single charging path: photovoltaic solar panels charge the 660 Ahr AGM battery bank throughout the day. The solar array adjusts to large tilt angles to maximize daily energy harvest based on site latitude and sun position. Easy-to-read meters on the unit display real-time charge rate during panel orientation at setup, guiding the operator to the optimal angle without estimation.

At the scheduled start time or automatically at dusk, the four LED fixtures activate and draw from the battery bank. The programmable control system manages the lighting cycle each night after initial setup, with no operator intervention required to start or stop the unit.

When grid access is available, the built-in 30A, 110VAC charger with external receptacle allows shore power top-off for pre-deployment preparation or scheduled maintenance charging.

440 Ahr vs. 660 Ahr: Which LTS-80 Configuration Is Right for Your Project?

Both configurations share the same trailer, mast, fixtures, and 500W standard solar array. The difference is battery storage capacity and the nightly runtime that stored capacity supports.

The 440 Ahr standard configuration is the practical choice for mid-latitude sites with consistent daily solar charging windows, projects running nightly schedules of 8 to 10 hours, and buyers for whom lower entry cost and standard rental fleet interoperability are priorities.

The 660 Ahr configuration is the better choice for high-latitude winter deployments with short daily charging windows, sites with partial panel shading that reduces daily harvest, nightly schedules exceeding 10 to 12 hours, or any project where maximizing the buffer between solar charge cycles is the primary operational concern.

Both variants support the same solar array upgrade path (500W, 750W, or 1,000W), which increases daily energy input and can partially offset the shorter winter charging window regardless of which battery capacity is selected.

Common Applications for the LTS-80 Solar Light Tower

The LTS-80 is suited for sites requiring fuel-free overnight illumination where silent and emissions-free operation are priorities and daily solar irradiance is sufficient to support the planned nightly runtime. Common deployment types include:

• Highway and roadway construction meeting OSHA 29 CFR 1926.56 illumination standards (https://www.osha.gov/laws-regs/regulations/standardnumber/1926/1926.56)
• Construction, mining, and utility sites in remote terrain with limited or no fuel delivery access
• Public works and infrastructure projects in EPA air quality nonattainment areas where diesel use is restricted
• Security and perimeter lighting at temporary facilities, staging areas, and remote infrastructure sites
• Outdoor events, concerts, and festivals where quiet engine-free operation is required
• Emergency response staging and disaster relief coordination
• Rental fleet deployment across short and long-term project intervals
• Projects where minimizing total cost of ownership over a multi-month deployment is the primary procurement factor

Sites deploying the LTS-80 for area and perimeter lighting commonly pair the tower with work zone traffic control equipment, including traffic cones and barricades.

LTS-80 vs. LTS-160N vs. LTS-300H: Choosing the Right Solar Light Tower

Trans Supply carries multiple Sunray solar light tower models to match different output, runtime, and site requirements.

The Sunray LTS-80 is the lightest and most compact model at 2,000 lb. with four 80W fixtures producing up to 51,200 lumens. The scalable solar array option (500W, 750W, or 1,000W) and straightforward controls make it a strong choice for rental fleets, smaller work zones, and deployments where transport efficiency and ease of operation are priorities.

The Sunray LTS-160N steps up to four 160W fixtures producing up to 109,000 lumens in a narrower transport profile designed for higher units-per-trip efficiency on multi-tower projects. Touchscreen controls with programmable scheduling provide more advanced operational management for longer-duration and higher-visibility deployments.

The Sunray LTS-300H is the solar and diesel hybrid option with three 330W solar collectors, a 600 Ahr battery bank, and an automatic diesel generator backup. It produces up to 163,200 lumens and is designed for deployments where continuous uninterrupted operation must be guaranteed regardless of daily solar availability.

Frequently Asked Questions About the Sunray LTS-80 Solar Light Tower

How does the Sunray LTS-80 solar light tower work?

The LTS-80 uses a 500W solar array to charge a 660 Ahr AGM battery bank during daylight. At dusk or the scheduled start time, four 80W LED fixtures activate and draw from stored battery power. Programmable scheduling manages the nightly cycle automatically after initial setup. There is no diesel engine or generator of any kind.

How many lumens does the LTS-80 produce?

At full brightness with all four 80W fixtures at maximum output, the LTS-80 produces an estimated 51,200 total lumens (12,800 per fixture). Mid setting at 50W per fixture produces approximately 34,120 total lumens. Low setting at 25W per fixture produces approximately 17,040 total lumens. Contact Trans Supply for the manufacturer-published spec sheet confirming exact total output figures at each setting.

Does the LTS-80 have a diesel engine or backup generator?

No. The LTS-80 is a pure solar unit with no diesel engine, no alternator, and no backup generator. It operates entirely on solar-charged battery power. A built-in 30A, 110VAC shore power charger with external receptacle is available for pre-deployment battery top-off when grid access is available.

What solar array sizes are available for the LTS-80?

The LTS-80 is configured with a 500W solar array as standard. Larger arrays of 750W and 1,000W are available. Higher-capacity arrays increase daily energy harvest, which extends available nightly runtime per charge cycle and reduces the risk of battery depletion before the scheduled stop time on long winter nights or overcast days.

What is the battery capacity on the LTS-80?

This configuration of the LTS-80 includes a 660 Ahr AGM sealed battery bank. A 440 Ahr configuration is also available. The 660 Ahr bank provides greater stored capacity for longer nightly runtimes between solar charges, which is particularly valuable at high-latitude sites with shorter winter daylight windows.

Is the LTS-80 a good option for rental fleets?

Yes. The LTS-80 is specifically noted for rental fleet suitability due to its simple operation, minimal maintenance requirements with no engine or alternator, and scalable brightness and scheduling settings. 2,000 lb. operating weight also makes it easier to position and maneuver on site compared to heavier hybrid and diesel tower models.

What is the mast height on the LTS-80?

The LTS-80 mast raises to 20 feet for field deployment, positioning the four LED fixtures for wide-area elevated illumination from a single unit position.
