Diesel Generator

Advantages of diesel generators

Diesel generators are power sources designed for situations that require prolonged and intensive use. Diesel engines offer lower fuel consumption and longer engine life compared to petrol engines. They are preferred as backup power sources on construction sites, farms, workshops, workplaces, and in areas where power outages are frequent. The category includes electric-start, single-phase diesel generators in the 9–11 kW class.

Selection criteria

• Power: The combined power of all devices that will run simultaneously and the starting currents of motor-driven devices must be taken into account.
• Phase: Single-phase models are suitable for 220 V devices; three-phase devices require a three-phase generator.
• Starting: Electric-start models are started easily with a key.
• Fuel tank: Tank capacity determines how long the generator can run without refueling.
• Noise level: If the generator will be used in residential areas, noise values should be compared.

Generator power ratings may be given in kVA and kW; kW represents usable power and is generally lower than the kVA value.

Installation and safe use

A diesel generator must be operated in an open, well-ventilated area; exhaust fumes can be fatal in enclosed spaces. Connecting the generator to a building's electrical installation must be done with a transfer switch that isolates the grid from the generator, and must be carried out by a qualified electrician. Grounding must not be neglected. The generator should be positioned in a place protected from rain but without obstructing airflow.

Maintenance

Timely replacement of oil, fuel, and air filters is the most important maintenance step for engine longevity in diesel engines. Generators that are not used for extended periods should be run at regular intervals, and the charge level of the starter battery should be checked. Keeping the fuel free of water and contaminants protects the injection system.

Frequently asked questions

How much fuel does a diesel generator consume?

Consumption depends on the load ratio and engine power; compare the values in the product information.

Will a three-phase motor run on a single-phase generator?

No; three-phase devices require a three-phase generator.

Does the generator come with a starter battery?

Whether the starter battery is included in the delivery is stated in the product description.

Can the generator run continuously?

Diesel generators are suitable for extended operation; maintenance intervals must be observed.

Is the noise level high?

Diesel generators are generally louder than petrol models; canopied models reduce noise.

What do you recommend for smaller needs?

For short-term and light use, you can look at petrol generators.
