Preliminary confirmation of your positioning

What is your primary use case? (Select the option that best describes how you plan to use the generator.)

Tab OptionRecommended Path & Rationale
Standby / Emergency Power
(For backup during grid outages in buildings, telecom sites, or essential services).
Path: Standard or Premium Packages.
Why: Reliability during infrequent use is key. A cost-effective standard model with automatic transfer switch compatibility is often sufficient.
Prime / Continuous Power
(For main power source at remote sites, mining, agriculture, or construction).
Path: Custom Configuration Highly Recommended.
Why: Durability and fuel efficiency under constant load are critical. Requires heavy-duty engine specs, larger cooling systems, and specific maintenance plans.
Rental & Variable Load
(For rental fleets or applications with highly fluctuating power demands).
Path: Custom or Resilient Package.
Why: Needs exceptional durability, ease of operation, and transportability. Skid or trailer mounts, robust canopies, and simplified controls are key priorities.

What matters most to you in this purchase decision?

Tab OptionImplications & Our Suggestion
Best Initial Price
(Seeking the most cost-effective upfront investment).
Focus on our Value Series. These models feature reliable domestic engines (Yuchai, Weichai) and standard controls, offering solid performance for basic needs. Ideal for tight budgets or less frequent use.
Brand Preference & Resale Value
(Preferring established engine brands like Cummins/Volvo for performance or market trust).
Explore our Premium Series. Configurations with Cummins, Volvo, or Perkins engines provide strong performance metrics and can enhance resale value. This is a common request from distributors.
Specific Configuration Need
(Requiring special features like super-silencing, trailer mounting, complex paralleling, or unique control panels).
You need a Custom Solution. This immediately flags you as an ideal candidate for our OEM/ODM services. We will engineer a unit to your exact technical and commercial specifications.

Our product list provides transparent pricing for each model to help you compare and find the best value for your specific needs and budget.

What is the average fuel consumption of a 100kW diesel generator?

A: At full load (100% capacity), a 100kW diesel generator consumes approximately 20 to 28 liters of diesel per hour. Actual fuel usage varies based on the load percentage, engine technology, and generator efficiency. Operating at 75% load will naturally be more fuel-efficient. Our product specifications include detailed fuel consumption data for each model to help you calculate operational costs accurately.

What are the primary applications for a 100kW diesel generator?

A: A 100kW diesel generator is a versatile power solution ideal for industrial, commercial, and large-scale backup power needs. Common applications include powering construction sites, manufacturing plants, data centers, hospital backup systems, agricultural operations, and large retail facilities. It provides reliable prime or standby power for mid-to-heavy electrical loads.

What should I consider when choosing between different brands of 100kW generators?

A: When selecting a brand, consider these critical factors:Reliability & Durability: Research the engine's reputation for long-term performance under heavy-duty cycles.Fuel Efficiency & Emissions: Compare fuel consumption specs and ensure the model meets local emission standards.Parts & Service Support: Verify the availability of local dealers for maintenance, repairs, and genuine spare parts.Warranty & Features: Compare warranty periods and the value of included features like advanced control panels or soundproofing.
