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.

“Standby only” ratings list the engine maker’s published standby power only; no prime (PRP) rating is published for that version.

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.

Data sources

Engine ratings: Guangxi Yuchai official product catalogue. Alternator capacities: STAMFORD | AvK official ratings. Values for reference at ≤1000 m, ≤40 °C; final data follows the order contract.
