The primary distinction is the power factor (pf).
kW (kilowatts): Measures the actual power used by the equipment.
kVA (kilovolt-amperes): Represents apparent power, including actual and reactive power.
The power factor (typically 0.8 for industrial generators) determines the relationship between kW and kVA. For example: kW = kVA × 0.8 0.8kW = kVA × 0.8 This distinction is vital for correctly sizing and understanding generator performance.
The power factor (pf) is the ratio of real power (kW) to apparent power (kVA). It reflects how efficiently a generator transfers power to the load:
Higher pf = Higher efficiency.
A standard industrial generator has a pf = 0.8.
For example, if a generator produces 500 kW of real power and 625 kVA of apparent power, the power factor is: 0.8 = 500 / 625 / 0.8 = 625 / 500
Yes, but this depends on the generator's design:
Reconnectable Generators: Voltage can be changed.
12-terminal: Switchable between three-phase and single-phase (output is reduced in single-phase).
10-terminal: Limited to three-phase voltages. Non-Reconnectable Generators: Voltage cannot be changed.
Automatic Transfer Switch (ATS):
Monitors the grid power and automatically switches to the generator during an outage.
Returns to the grid power when it comes back on.
Commonly used in environments requiring high availability, such as data centers or hospitals.
Yes, generators can be connected in parallel:
For Redundancy or Capacity Increase: Connecting the same generators in parallel is easier. Different Generators: Parallel connection requires careful design and consideration of engine configuration, generator design, and voltage regulators.
Most commercial generators can be converted as follows:
General Rule: 60 Hz machines operate at 1800 RPM; 50 Hz machines operate at 1500 RPM.
The conversion involves adjusting the engine speed. In some cases, part replacement or modification may be required.
Correct sizing is critical to prevent damage to the generator or connected equipment:
Key Considerations: Power load requirements, primary and backup use, and application specifications.

With proper maintenance, a quality diesel generator will last forever. Regular oil changes and keeping the air filter clean are important. Clean fuel is extremely important.
Diesel generator kW (k=1000 W=W) is generally produced at low RPMs. Example: 8 kW = 8000 Watts. It takes 1.5 horsepower to produce one kW. A diesel generator running at a slow 1800 RPM requires a large displacement. Most gasoline generators, and even some diesel generators, operate at 3600 RPM. These are considered high-speed, disposable generators. Their initial cost is low, but they wear out quickly and are not worth repairing. We only sell diesel generators that operate at 1800 RPM. Diesel generators producing kW from 1800 RPM engines and generators last almost forever. That's why they are sometimes referred to as investment class.
