Features and BenefitsRobust Design–
The generator is designed to operate in cold weather with performance down to 0 °F (-18 °C) out of the box. The extreme cold weather models can perform down to -40 °F (-40 °C) out of the box. It is tested and certified per the latest EPA, UL, and CSA standards.
The generator meets NFPA 37 which allows it to be installed 18 inches from a building. It has powerful motor starting ability and can easily start and run a 5-ton A/C¹ under full pre-load.
Intelligent Load Management- The generator can control up to 4 loads and continuously monitors how much power is required independently for each load. It then controls each load for maximum utilization of generator power by only restoring loads the generator has capacity to run.
Flexible Exercise Modes- Exercise modes can be set for time, date, and frequency that suits the owner. Our patented ‘Crank only’ exercise mode allows the generator to crank the engine and run diagnostics without starting the engine. This reduces wear and tear on the engine, fuel costs, and further reduces the sound of an already quiet generator.
Remote Monitoring- Remote monitoring is built into every generator. Using a computer, tablet, or smartphone, an operator can monitor, change exercise modes, and manually run the generator remotely.
Generator and ATS packaged sets – The RS20AC comes with a 20-kW generator and 200A service entrance-rated ATS in one box to make ordering more convenient.
