Silent Canopy: The most prevalent format. Enclosed in a heavy steel, weatherproof sound capsule. These keep noise down to a very respectable 65–70 dB(A) at 7 meters, making them compliant with residential and commercial office zones.Open Frame: Stripped of the enclosure. Used primarily inside purpose-built generator plant rooms or out on open agricultural land where noise is not a factor.ATS Integration: These systems almost always come with or support an Automatic Transfer Switch (ATS) controller (such as a Deep Sea Electronics module), allowing the generator to start entirely on its own within seconds of a power grid failure
