Weichai Genset Technical Selection Table — WP / M Series, 10–3000 kW

Power definitions (ISO 8528)

• PRP (Prime) — unlimited-hours base power; 10% overload for 1 h in every 12 h.
• ESP (Standby) — emergency maximum, no overload (typically +10% over prime).
• Rated current I = Prime kW / (√3 × 400 V), three-phase PF 0.8.

Engine-to-set matching

Engines are sized with a power reserve over the alternator prime output (industry rule ≈ 1.05–1.22×). Every engine kW figure below is taken from the engine maker's published 1500 rpm / 50 Hz rating, not estimated.

“Factory-engineered / paralleling · reconfirmed per order” ratings exceed the engine maker’s largest single-engine 50 Hz rating; these are delivered as multi-engine paralleling sets or custom builds. The exact engine configuration is confirmed against the order, so no single engine model or rating is listed.

Configuration & options

• Alternator: genuine Stamford, brushless, H-class, IP23, PF 0.8.
• Controller: SmartGen HGM series standard; Deep Sea DSE6120/7320 on request.
• Open / silent / super-silent / trailer types; ATS, parallel & remote-monitoring optional.
