Solar Light Tower- UNI-T3

UNI-T3 UST-900L Mobile Solar Light Tower

The UNI-T3 (UST-900L) is a trailer-mounted mobile solar light tower designed for construction sites, infrastructure projects, industrial yards, roadwork, emergency response and other outdoor areas that require flexible lighting without a permanent grid connection.

The system integrates three 490W bifacial solar panels, an 11.7kWh LFP battery, four LED floodlights, a motorized lighting platform and a towable trailer. Its mobile design allows the lighting tower to be transported and positioned where temporary or off-grid illumination is required.

High-Output LED Lighting

The UNI-T3 is equipped with four 100W IP67 LED floodlights, with a stated maximum output of up to 64,000 lumens. The lights support dimming and timer control, helping users adjust brightness and operating schedules according to site requirements.

The lighting platform supports 360-degree motorized rotation and 0–90-degree motorized adjustment through a linear actuator. This helps direct light toward different work areas without manually repositioning the complete trailer.

Solar Power and Battery Storage

The system uses three 490W bifacial and BC solar panels with a total rated solar input of 1,470W. The 460Ah, 25.6V LFP battery provides 11.7kWh of energy storage and includes a heater. The supplied specification states a battery service life of more than 10 years.

The listed solar recharge time is approximately 7.6 hours in peak sun, while the stated operating time is approximately 26.5 hours at 100% brightness. Actual charging time and runtime vary according to sunlight, temperature, battery condition, brightness settings and operating environment.

Mobile Trailer Design

The UNI-T3 uses a US DOT trailer with a 2-inch ball hitch and single axle. Four outriggers help stabilize the unit after positioning, while forklift pockets support handling and transport planning. The high-tensile steel mast is hot-dip galvanized and uses a square design.

The mast can reach a stated height of 6.3m in approximately 5 seconds with the standard manual winch lifting system. The supplied specification lists a wind rating of 117km/h. Confirm local towing, transport, anchoring and installation requirements before deployment.

Remote Monitoring and Optional Upgrades

A 60A MPPT controller with remote monitoring is included in the listed configuration. Optional upgrades include an 8.5m mast, electric lifting, hydraulic lifting, a Victron system, a Victron touch panel, a 4G router, an auto-start DC generator and a remote fuel tank reader.

Optional equipment, pricing and compatibility should be confirmed according to the final project requirements and destination-market regulations.
