What technical specifications matter most for compliance?

The two figures that matter most are the rated noise level in decibels at a standard reference distance and the engine's emissions tier, both of which should appear on the manufacturer's technical sheet. Fuel consumption rate and load capacity matter too, since running a generator well outside its efficient load range can indirectly push emissions higher. Canopy type and exhaust configuration also affect real-world noise performance beyond the base engine rating. Sparkline Group provides these specification sheets alongside every generator supplied on rental. Reviewing them before deployment, not after a complaint, is the better sequence.
