Stephill 20.0 kVA Kubota Super Silent Multi Phase Diesel Generator

Engineered for demanding commercial, industrial and hire‑fleet environments, the Stephill SSDK20M Diesel Generator delivers robust, continuous power with exceptional acoustic performance. Built around a 1500rpm EU Stage V Kubota water‑cooled diesel engine, it provides reliable long‑duration operation with reduced fuel consumption and extended service life. The super‑silent Zintec steel acoustic cabinet ensures noise levels as low as 64dB(A) @ 7m, making it suitable for residential, commercial and event applications.

A Deep Sea DSE3110 controller, lockable control housing and a brushless AVR‑controlled alternator provide stable voltage regulation and secure operation. With a large 120L fuel tank delivering up to 26 hours runtime, extensive socket options and a rugged corrosion‑resistant build, the SSDK20M is a dependable, site‑ready solution for continuous or variable electrical loads.
