Frequently asked questions about diesel power generators for professional use

A diesel generator can last 15 to 30 years with proper maintenance and professional use. Actual service life depends on the hours of operation per year, load rating, engine and alternator quality, and maintenance regime. Industrial engines from brands such as Perkins, Volvo Penta and Cummins remain reliable even after thousands of hours of operation.

kVA (kilovolt amperes) indicates apparent power, while kW (kilowatts) indicates actual usable power. The difference is determined by the power factor, usually 0.8 for standard industrial applications. Thus, a 100 kVA generator delivers about 80 kW of effective power. Correct sizing prevents overloading and reduces wear and tear.

Maintenance includes periodic oil changes, replacement of fuel and air filters, coolant checks, battery tests and regular running of the generator under load. Preventive maintenance prevents breakdowns, increases service life and ensures a stable power supply.

The right type of generator depends on power output, type of consumers, peak loads, operating time and environment. Construction sites, industrial sites and emergency power systems each have different requirements. Correct sizing ensures optimum performance and maximum reliability.

A properly reconditioned used generator can be just as reliable as a new machine. Important are a thorough inspection, maintenance of wear parts and correct installation. This makes used generators a cost-effective solution for professional use.

Fuel consumption varies depending on load, generator capacity and hours of operation. For example, a 100 kVA generator consumes an average of 20-25 liters of diesel per hour at full load. Monitoring consumption helps with cost planning and optimizing operational efficiency.

Yes, generators can be connected in parallel to provide greater power or redundancy. This is useful in large-scale construction or industrial projects. Correct synchronization and load balancing are essential to prevent damage.

High temperatures, low humidity or high lying can affect the power and efficiency of a diesel generator. Cooling, air intake filters and correct sizing keep performance at optimum levels.

Safety is critical. Generators should always be in well-ventilated areas, properly grounded and fuel stored safely. Avoid overloading and follow the operation and maintenance manual.

Diesel generators have longer life, higher reliability and better fuel efficiency than gasoline or gas generators, especially under long or heavy loads. They are suitable for industrial and construction applications.

Generator power is determined by the total load of connected equipment plus peak load. Consider continuous load and possible expansions to ensure optimal performance. Read more about it in our blog article: read more.

Regular inspections, proper operation, oil and filter changes, and avoiding overloading maximize the life of your diesel generator. Always follow the maintenance guide and manufacturer's instructions.
