Diesel Generator Sets
A generator set is a self-contained unit that produces electricity using an internal combustion engine coupled to an alternator, to provide power where the grid does not reach or as a backup in the event of power outages.
The Genergy GDS series consists of 1,500 RPM, soundproofed, single-phase and three-phase diesel generators ranging from 10 to 358 kVA. Featuring a Genergy SGE engine, a copper alternator, a Deep Sea controller, and automatic transfer switch (ATS) readiness, these generators provide continuous and reliable power for homes, businesses, construction sites, and industrial applications.

What is a generator set?
A generator set is a self-contained power solution that generates electricity in areas without access to the power grid, or that serves as a backup system during a power outage. Unlike a simple generator (which consists solely of an alternator), a generator set is a complete unit: it includes an internal combustion engine, an alternator, a cooling system, a fuel tank, a control panel, and protective devices.
Their function is to ensure a continuous and stable power supply, both for permanent use (industry, critical facilities) and in emergencies (homes, businesses, hospitals). Models with automatic transfer switches (ATS) detect a power outage, start up automatically, and maintain power until the grid is restored. At Genergy, you’ll find 1,500 RPM diesel generators—single-phase and three-phase, soundproofed—ranging from 10 to 358 kVA.
GDS Series Generator Sets
Diesel, 1,500 RPM, soundproofed, with a Deep Sea controller, and set up for automatic start. Filter by power output based on your setup.
How much power do you need?
Guideline by type of use. Add up the power consumption of the devices that will be running at the same time and add a 20–30% margin for startup peaks. If you have any questions, we’re here to help.

Copper Alternator
Self-excited synchronous alternator, 100% copper windings, with low harmonic distortion (THD) for clean power.
Deep Sea Controller
A high-end control panel that monitors all parameters, alerts users to anomalies, and shuts down the equipment if necessary.
Soundproof booth
Bodywork that reduces noise and protects the engine from rain, dust, and impacts (approx. 60–75 dB, depending on the model).
ATS-Ready
Ready for automatic startup in the event of a power failure (requires a transfer switch) and remote startup via contact.
Easy and reliable starting
Battery-powered push-button electric start, and coolant heater to ensure a smooth start even in cold weather.

Frequently Asked Questions
What is the difference between a power set and a generator?
The electric generator is simply the component that converts mechanical energy into electrical energy (the alternator). A generator set is the complete unit: internal combustion engine, alternator, cooling system, fuel tank, control panel, and protective devices. In practice, a generator set is a ready-to-use solution.
How much power do I need for my home or business?
Add up the power consumption of the equipment that will be running at the same time and include a 20–30% margin for startup peaks. As a general guideline, a residential home typically requires 10–14 kVA, and a business or workshop requires 20–27 kVA. Construction sites and industrial facilities require higher power ratings.
What does 1,500 RPM mean, and why is it better?
It indicates that the motor runs at a lower speed than those operating at 3,000 RPM. This results in less vibration and wear, a longer service life, lower fuel consumption, and less noise. It is the professional choice for continuous or intensive use.
What is Automatic Start-Up (ATS)?
This system detects a power outage, automatically starts the generator set, and shuts it down when power is restored. The GDS units are ATS-ready, but the transfer switch must be purchased separately depending on the model (from 63A to 630A).
Are they noisy?
GDS models are soundproofed (enclosed), with a noise level of approximately 60–75 dB at 7 meters, depending on the model and load: suitable for environments where noise levels are regulated.
What kind of maintenance do they need?
Simple routine maintenance: oil changes based on hours of operation, filter inspection and cleaning, general cleaning, and start-up tests. The GDS design provides easy access to the engine to reduce maintenance time.
Power ratings and noise levels are approximate and vary depending on the model and load.
