How to read the columns

Methodology
Smallest unit kW
Lowest published electrical output of one generating unit in the named Lines, in kWe. Portfolio minima may include portable models. Standby where available; kVA-only figures assume 0.8 power factor. Consult Rating basis and scope; blank when unverified.
Largest unit kW
Highest published electrical output of one generating unit in the named Lines, in kWe. Standby where available; other duty and frequency bases are disclosed in Rating basis and scope. kVA-only figures assume 0.8 power factor. Mechanical output and multi-unit totals are excluded.
HVO approved
The vendor states that the named diesel lines are approved or released for HVO (renewable diesel, EN 15940 paraffinic fuel). Blank means no such statement was found on the pages read.
Emissions certification
Emissions standards the vendor names for the named lines: US EPA Tier 2 (emergency standby) or Tier 4 Final, EU Stage V, TA Luft, CPCB IV+ (India). Certifications vary by model and market.
Engines
Whether the vendor builds the engine or turbine itself or packages engines bought from another maker, per the vendor's own pages.
Data center offer
Dedicated: the vendor names a product line or program for data centers. General: a standard range the vendor documents in data center use. Rental: the vendor rents fleet units for data center bridge or backup power.
Lines
The product series this record covers. Ratings, fuels and emissions refer to these lines, not to the vendor's whole portfolio.
