FAQ
Q: Are Chinese-brand diesel Generatoren zuverlässig?
A: Top Chinese brands have improved significantly in the last decade. Engines from Yuchai, SDEC, and Weichai can reach 15,000-20,000 hours with proper maintenance—comparable to mid-range Western brands from 15 years ago. The key differentiator is quality control consistency and parts availability.
Q: What’s the minimum I should spend on a reliable diesel generator?
A: For a basic standby generator: $200-400/KW. For a generator you’d trust with critical loads (Krankenhaus, Rechenzentrum): $400-800/KW. Below $150/KW, expect significant compromises in engine quality, alternator regulation, and after-sales support.
Q: Can I save money by buying direct from China?
A: You can save 30-50% compared to local dealer pricing. Jedoch, you assume all responsibility for: import duties and customs clearance, freight and shipping damage, local electrical code compliance and certification (UL/CSA/CE), warranty claims (shipping parts back to China), Installation, and commissioning. This is viable for experienced importers; risky for first-time buyers.
