Overview
The SG 50 kW silent diesel generator pairs a Weichai WP4.1D66E200 4-cylinder water-cooled, turbocharged diesel engine (4.087 L, 60 / 66 kW) with a brushless, self-excited alternator with AVR and class H insulation. It is rated 50 kW / 62.5 kVA at 400/230 V, three-phase four-wire, 50 Hz, power factor 0.8 and rated current 90 A.
A SmartGen 6110 controller with auto mains failure (AMF) function monitors mains and generator values, signals a changeover switch panel and shuts the set down on faults; the engine starts electrically at 24 V DC. The set sits in an enclosed canopy on a steel base frame with anti-vibration pads and an integral 100 L fuel tank, and measures 2400 × 1000 × 1300 mm with a dry weight of 1000 kg. The photographs show the teal canopy used across the 50–100 kW range; canopy colour is confirmed in the order.
