The UNI-Block UBT-300S is a heavy-duty solar street light and off-grid area lighting system for industrial, construction, security and remote applications. It combines a 490W bifacial solar panel, 2.9kWh LFP battery, two 300W IP67 LED floodlights and a 40A MPPT controller with remote monitoring. The stated operating time is up to 26.4 hours at 50% brightness, subject to weather and configuration.
The UNI-Block UBT-300S is a heavy-duty off-grid solar lighting system designed for industrial yards, construction sites, temporary work zones, remote facilities and outdoor areas without a reliable grid connection.
It integrates a 490W bifacial solar panel, a 2.9kWh LFP battery, two high-output LED floodlights and a 40A MPPT controller in one relocatable lighting block. The system provides powerful area illumination while reducing the need for trenching, grid cabling and permanent electrical infrastructure.
The standard configuration includes two 300W IP67 LED floodlights with a stated maximum output of up to 32,000 lumens. Motion sensor and timer functions help adjust lighting operation according to site activity and scheduled requirements.
The system uses one 490W bifacial and BC solar panel to recharge a 230Ah, 12.8V LFP battery with a 2.9kWh capacity. The battery is equipped with a heater, and the supplied specification states a service life of more than 10 years. Charging time is approximately 5.5 hours in peak sun, depending on weather and operating conditions.
A 40A MPPT controller with remote monitoring is included in the listed configuration. Optional upgrades include a Victron remote system, an industrial 4G LTE router, a 180° panoramic 4MP PTZ camera with 10-day video retention, active deterrence with two-way audio, concrete ballast and heavy-duty stabilizing outriggers.
The mast is made from high-tensile hot-dip galvanized steel and uses a square design. It features a 3.5m mast, manual winch lifting and a stated wind rating of 117km/h. The durable base includes HDG forklift holes, while internal and external anti-corrosion powder coating helps support outdoor deployment.
