Overview

The SG 20 kW silent diesel generator pairs a Weichai WP2.3D25E200 4-cylinder water-cooled diesel engine (2.3 L, 23 / 25 kW) with a brushless, self-excited alternator with AVR and class H insulation. It is rated 20 kW / 25 kVA at 400/230 V, three-phase four-wire, 50 Hz, power factor 0.8 and rated current 36 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 12 V DC. The set sits in an enclosed canopy on a steel base frame with anti-vibration pads and an integral 60 L fuel tank, and measures 1500 × 870 × 1200 mm with a dry weight of 550 kg. The photographs show the white canopy used across the 15–30 kW range; canopy colour is confirmed in the order.
