GENERGY Three-Phase Generators: Professional-Grade Power for Demanding Applications

At GENERGY, we offer high-performance energy solutions, including our three-phase generators, available in both diesel and gasoline models. These units are designed to meet everything from moderate to high energy demands, with three-phase generator capacities ranging from 6,000 W to 275 kVA, ensuring a reliable, efficient, and durable power source.

GENERGY Three-Phase Diesel Generator Series

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

Three-Phase Gasoline Generators

GENERGY three-phasegasoline-powered generatorsare ideal for professional applications requiring mobility and medium power. They include models with electric start and high-capacity fuel 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: 7,000 W at 400 V and 5,400 W at 230 V. The Formigal-S model features a manual start and longer runtime.

- High-Power Range:

  - Somport-S: 9200W

  - Cervascán: 12000W

  - Izoard-S: 15000W

  - Stelvio-S: 18000W

All feature electric start and are designed for demanding applications.

Three-Phase Diesel Generators at 1500 RPM

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

- Available power ratings range from 20 kVA (GDS20T) to 275 kVA (GDS275T).

Features of the Three-Phase Group

Three-phase power systems are known for their high efficiency in power transmission. A three-phase diesel generator can deliver three times more power than an equivalent single-phase generator, with greater stability and lower losses.

- Higher performance in a smaller package.

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

- Improved utilization of the electrical system and reduced operating costs.

Advantages of Three-Phase Generators

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

- Higher usable power: Up to 1.5 times more than its single-phase equivalent.

- Vibration reduction: Thanks to the constant instantaneous power transmitted.

- More efficient neutral: Balanced loads place less strain on the neutral wire.

- Superior electrical stability: Ideal for sensitive machinery.

- Backward compatibility: It can power single-phase equipment.

- Less mechanical wear: Less stress on the 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 230V.
• Maintain more stable power delivery under heavy loads.
• Meeting needs ranging from moderate power requirements to high energy demands, with gasoline and diesel models.
• Integration into emergency, continuous-use, or backup power applications.

Uses of a three-phase diesel generator

• Industries, workshops, and factories with three-phase machinery.
• 380V three-phase generator for construction sites and projects involving high-power 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.
• Solar photovoltaic or wind generators as backup power sources, particularly for three-phase diesel generators.
• Homes with three-phase electrical service and high power requirements.

Integrations of 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 generator 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’s not the best option. Three-phase generators can be configured to power single-phase devices, but they will only operate at about 50% of their capacity. For continuous single-phase use, it’s better to purchase a dedicated unit.

Can I use a three-phase generator at home?

Yes, a three-phase generator can be used in a home only if the electrical system 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 consulting

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

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

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

 Approximate consumption

• Between 1.5 and 4 liters of fuel per hour
• The higher the load and power, the higher the consumption
• Diesel models are generally more fuel-efficient during extended use

Actual power consumption always varies depending on the load percentage.

 

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

The power required for a factory typically 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
• Ongoing or occasional energy needs

In industrial settings, it is essential to conduct 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 its power output, brand, and soundproofing level.
