Generac MLT4200

The Generac MLT4200 is a diesel-powered mobile light tower built for the harshest job-site conditions, from desert heat to frozen tundra. Powered by an Isuzu liquid-cooled diesel engine paired with a Marathon Electric brushless generator, it delivers up to 20 kW of export power - effectively combining a light tower and a generator in one unit. Four 320W LED luminaries mount on a 23 ft fully rotational steel mast that deploys electrically in just 15 seconds, illuminating up to 28,000 sq ft. A 51.4-gallon fuel tank provides up to 48 hours of runtime, while the four-point outrigger stance handles wind speeds up to 65 mph.
