Overview
The SG 40 kW silent diesel generator pairs a Weichai WP2.3D48E200 4-cylinder water-cooled, turbocharged diesel engine (2.3 L, 44 / 48.4 kW) with a brushless, self-excited alternator with AVR and class H insulation. It is rated 40 kW / 50 kVA, three-phase four-wire, 50 Hz, power factor 0.8 and rated current 72 A.
A SmartGen 6120 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 12 V DC. The set sits in an enclosed canopy on a steel base frame with anti-vibration pads and an integral 70 L fuel tank, and measures 2150 × 900 × 1200 mm with a dry weight of 850 kg. The photographs show the yellow canopy used across the 40 kW range; canopy colour is confirmed in the order.
