Perkins 1104A-44G
Perkins 1104A-44G. Gross mechanical prime/standby: 42.4/46.6 kW at 1500 rpm, 47.3/52 kW at 1800 rpm. Source: supplied TPD1567E2 November 2019 p.2, corroborated by a separate Perkins Technical Data sheet p.1 hosted at https://www.wintpower.com/uploads/1104A-44G.pdf. Source discrepancy retained: the 2019 cover states 46.5 kW at 1500 rpm, whereas both general-installation and energy-balance tables state 46.6. Imported 46.6 as the corroborated tabulated standby value, not as a manufacturer-issued correction. Catalogue power_kw is maximum documented standby; no electrical output or emissions certification inferred. Production status is unknown. Discontinued is the user-authorized catalogue classification, not manufacturer-confirmed cessation; no production-end year is asserted.
