Weifang 20kW Diesel Generator Set

The 20kW / 25 kVA generator unit is driven by an industrial Weifang 4-cylinder naturally aspirated diesel engine engineered for simple, low-maintenance prime and standby power per ISO 8528 standards. Utilizing an in-line mechanical injection pump and mechanical governor, the engine operates reliably without sensitive electronic ECU boards, ensuring high tolerance to low-grade or high-sulfur diesel and allowing routine servicing with standard mechanical tools. Under steady prime duty cycles (75% to 100% continuous load), brake-specific fuel consumption averages 225 to 235 g/kW·h (approximately 5.2 to 6.8 liters per hour). To match site distribution requirements, the brushless alternator can be wound for standard 3-phase 4-wire (400V/230V at 50Hz, 480V/277V at 60Hz) or configured for dedicated single-phase (230V or 240V/120V) for remote telecommunication base stations, poultry farms, and residential backup.

At standard 400V/230V 3-phase operation, nominal continuous current is approximately 36 Amperes. Electrical protection is handled by a chassis-integrated 50A to 63A 3-pole thermal-magnetic circuit breaker (MCB or compact MCCB) engineered for rapid short-circuit isolation and thermal overload protection. For noise-sensitive residential, agricultural, or small commercial perimeters, the unit is fitted inside a compact weatherproof soundproof canopy with high-density acoustic lining and an integrated residential-grade exhaust silencer, suppressing operational noise to 65–68 dB(A) at 7 meters. The control console utilizes a SmartGen (HGM series) or Deep Sea (DSE4520) digital controller with automatic mains failure (AMF) logic, supporting automated two-wire remote start signals and full integration with an external Automatic Transfer Switch (ATS) to restore emergency power within 8 to 12 seconds of utility loss.
