Buying Tips for 500kW Generator Sets

1. Verify real power output — Ensure the PRP (Prime Power) rating matches your needs, not just the standby rating
2. Check voltage compatibility — 400V/480V is standard; 6.6kV/11kV requires additional engineering
3. Request load bank test reports — A proper factory test confirms performance
4. Compare warranty terms — 12 months or 2000 hours is standard; negotiate for longer
