FAQ

Diesel Generator Sets & Parts
1. What's the fuel consumption of your diesel generators?
Fuel use varies by model. Check specs for exact rates.
2. How often should I maintain a diesel generator?
Service every 250-500 hours or 6 months, including oil/filter changes and battery checks.
3. Why does my diesel generator emit black smoke?
Caused by clogged air filters, overloading, or faulty injectors. Clean filters or reduce load.
4. Are spare parts compatible with other brands?
Standard parts (filters, belts) may fit; engine-specific components (pistons) likely require originals.

Gas Generator Sets & Parts
1. What gases can your generators use?
Supports natural gas and biogas. Ensure gas quality matches specs.
2. How efficient are gas generators vs. diesel?
Gas models cost less to run and pollute less but may have slightly lower power density (30-45% efficiency).
3. How long do spark plugs last in gas generators?
Replace every 1,000-2,000 hours or if misfires/power loss occurs.
4. Can I convert a diesel generator to gas?
Yes, with a retrofit kit (carburetor, ignition system). Professional installation required.
5. Why does my gas generator shut down randomly?
Check gas pressure, coolant levels, or sensor errors via the control panel.

General FAQ
1. Do you offer warranties?
Whichever comes first, 1 year or 1500 hours(Excluding vulnerable parts).
2. How to reduce generator noise?
Use soundproof enclosures or choose low-noise models (e.g., canopy-type generators).
3. How to order spare parts?
Search by model number on our website or contact sales for bulk/custom orders.
