Solar Light Tower for Sale: Sunray LTS-80 (500W / 440 Ahr)

The Sunray LTS-80 by National Signal is a portable solar light tower built for continuous field use across construction, mining, utility, security, and event applications. A 500W solar array charges a 440 Ahr AGM battery bank during daylight. Four 80W LED fixtures draw from that stored power overnight across three selectable brightness settings. There is no diesel engine, no alternator, and no fuel requirement.

This page covers the standard 440 Ahr configuration of the LTS-80. A higher-capacity 660 Ahr variant is also available at https://www.trans-supply.com/Solar-Light-Tower-LTS-80-660AHR for deployments requiring longer nightly runtimes or operation in high-latitude winter conditions with shorter daily charging windows.

How the LTS-80 Solar Charging System Works

The LTS-80 operates on a single charging path: photovoltaic solar panels charge the 440 Ahr AGM battery bank throughout the day. The solar array adjusts to large tilt angles and includes easy-to-read charge meters that display real-time output during panel orientation at setup, guiding the operator to the optimal angle without estimation or guesswork.

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 nightly cycle after initial setup, with no operator intervention required to start or stop the unit on subsequent nights.

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. H2: Sunray LTS-80

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 Light Tower Model

The Sunray LTS-80 is the lightest model in the Trans Supply light tower lineup at 2,000 lb., with four 80W fixtures producing up to 51,200 lumens and a scalable solar array from 500W to 1,000W. Simple controls and low maintenance requirements make it the preferred choice for rental fleets and smaller work zones.

The Sunray LTS-160N steps up to four 160W fixtures producing up to 109,000 lumens, with a narrow transport profile designed for higher units-per-trip efficiency on multi-tower projects and touchscreen scheduling controls for more complex operational management.

The Sunray LTS-300H is the solar and diesel hybrid option, producing up to 163,200 lumens with an automatic diesel generator backup that guarantees continuous uninterrupted operation regardless of daily solar availability. It is the appropriate choice when weather-independent runtime assurance is a project requirement.

Frequently Asked Questions About the Sunray LTS-80 440 Ahr Solar Light Tower

What is the difference between the LTS-80 440 Ahr and the LTS-80 660 Ahr?

Both configurations share the same trailer, mast, four 80W LED fixtures, and 500W standard solar array. The 440 Ahr version is the standard configuration suited for mid-latitude sites with consistent daily solar input and nightly schedules up to approximately 10 hours. The 660 Ahr version provides greater stored battery capacity for longer nightly runtimes, high-latitude winter deployments, and sites with reduced daily solar harvest due to shading or short winter daylight windows.

How many lumens does the Sunray 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 to request the manufacturer-published spec sheet confirming 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 present.

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. A higher-capacity array increases daily energy harvest and extends available nightly runtime per charge cycle, which is particularly valuable on sites with long overnight schedules or reduced winter daylight.

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

Yes. The LTS-80 is suited for rental fleet use due to simple operation, minimal maintenance with no engine or alternator, silent operation, and scalable brightness and scheduling settings. It's 2,000 lb. operating weight also makes it the most manageable unit in the Sunray light tower lineup for on-site positioning and trailer loading.

Can the nightly run time be programmed on the LTS-80?

Yes. The LTS-80 control system includes programmable automatic on/off at dusk and dawn and settable nightly run times from 3 to 12 hours. After initial setup, the unit manages the lighting cycle automatically each night without requiring the operator to return to the unit.

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.
