Three-phase Generator

GENERGY Three-Phase Generators: Professional Power for Demanding Applications

At GENERGY, we offer high-performance energy solutions, including our three-phase generators, available in diesel and gasoline versions. This equipment is designed to meet medium to high energy demands, with three-phase generator power ranging from 6000W to 275KVA, ensuring a reliable, efficient, and long-lasting power source.

GENERGY Three-Phase Diesel Electric Generator Range

Our range of three-phase diesel generators is divided into two main categories according to fuel type: gasoline for medium power and diesel at 1500 RPM for demanding jobs and intensive use.

Three-phase Gasoline Generators

GENERGY three-phasegasoline generatorsare ideal for professional applications that require mobility and medium power. They include models with electric start and large capacity tanks:

- Candanchú three-phase diesel generator: 7000W or 5400W single-phase, with electric start and professional-grade performance.

- Formigal / Formigal-S three-phase diesel generator: 7000W at 400V and 5400W at 230V. The Formigal-S model adds manual start and greater autonomy.

- High Power Range:

  - Somport-S: 9200W

  - Cervascán: 12,000W

  - Izoard-S: 15,000W

  - Stelvio-S: 18,000W

All with electric start and designed for demanding applications.

1500 RPM Three Phase Diesel Generator Sets

Designed for continuous and intensive operation, GENERGY 's three-phase diesel generator sets are robust, efficient and available in open or soundproofed versions. They do not require additional kits to support photovoltaic or wind power systems, although they do require an ATS panel if used as emergency generators.

- Power ratings available from 20KVA (GDS20T) to 275KVA (GDS275T).

Characteristics of Three-Phase Systems

Three-phase power systems are characterized by their high efficiency in transporting energy. A three-phase diesel generator can move three times more energy than an equivalent single-phase generator, with better stability and less loss.

- Higher performance with smaller size.

- Ideal for industrial installations and environments where high power is required.

- Better use of the electrical system and reduction of operating costs.

Advantages of Three Phase Generators

Purchasing a GENERGY three-phase diesel or gasoline generator offers numerous benefits over single-phase systems:

- Greater useful power: Up to 1.5 times more than its single-phase equivalent.

- Vibration reduction: Thanks to the consistency of the instantaneous power transmitted.

- More efficient neutral: Balanced loads generate less load on the neutral wire.

- Superior electrical stability: Ideal for sensitive machinery.

- Backward compatibility: Can power single-phase equipment.

- Less mechanical wear: Less fatigue on motor shafts.

Functions of a three-phase generator

• Generate three-phase electricity for high-demand facilities and equipment.
• Provide continuous or backup power in professional and industrial settings.
• Power three-phase machinery as well as compatible single-phase equipment.
• Provide an outlet for 400V and, in many models, also at 230V.
• Maintain a more stable power delivery under heavy loads.
• Meeting needs ranging from moderate power requirements to high energy demands, with gasoline and diesel models.
• Integrated into emergency, continuous-duty, or backup power applications.

Uses of a three-phase generator

• Industries, workshops, and factories with three-phase machinery.
• Construction projects using heavy-duty equipment.
• Agricultural facilities and pumping systems or electric motors.
• Businesses and professional facilities that cannot stop their operations.
• Electrical backup systems for critical buildings or processes.
• Photovoltaic or wind power applications as backup power sources, particularly for three-phase diesel generators.
• Homes with three-phase electrical service and high power requirements.

Connections for a three-phase generator

• Three-phase electrical systems of 400V.
• Mixed networks with outputs 400/230V depending on the model.
• Industrial machinery, electric motors, and professional tools.
• ATS systems for automatic start-up in emergency applications.
• Photovoltaic or wind power systems as backup power sources for certain diesel generators.
• Industrial, agricultural, and construction environments with high power demands.
• Single-phase equipment is compatible when the installation is properly balanced. 

Frequently asked questions about three-phase generators

Can a three-phase electric generator be used as a single-phase generator?

Yes, although it is not recommended. Three-phase generators can be configured to power single-phase devices, but they will only use around 50% of their capacity. For continuous single-phase use, it is preferable to purchase specific equipment.

Can I use a three-phase generator at home?

Yes, a three-phase generator can be used in a home only if the electrical installation is three-phase.

If the home is single-phase, the three-phase generator cannot be used directly without:

• Suitable adapters
• Conversion to single-phase
• Specialized technical advice

Using a three-phase generator without a compatible installation can cause electrical imbalances and damage to equipment.

 How much fuel does a three-phase generator consume per hour?

The consumption of a three-phase generator depends on its power, motor type, and connected load.

 Approximate consumption

• Between 1.5 and 4 liters of fuel per hour
• The greater the load and power, the greater the consumption.
• Diesel models tend to be more efficient in prolonged use.

Actual consumption always varies depending on the percentage of load used.

 

How much power does a three-phase generator need for a factory?

The power required for a factory usually ranges from 50 kW to over 200 kW, depending on the size and type of machinery.

Factors to consider

• Number of machines operating simultaneously
• Starting power of industrial motors
• Hours of daily use
• Need for continuous or occasional energy

In industrial environments, it is essential to carry out a preliminary technical study.

How much will a three-phase electric generator cost in 2026?

The price of a three-phase generator in 2026 varies depending on power, brand, and soundproofing level.
