50 kVA Generator Sets
A 50 kVA generator set is a high-power diesel unit designed for continuous operation in industrial, construction, agricultural, and hospitality settings, as well as for providing backup power to critical facilities that cannot afford a power outage.
Genergy's GDS diesel generator series, with a power range of approximately 50 kVA, ranges from 27 to 94 kVA. It is three-phase (400/230 V), features a 1,500 RPM engine, a copper alternator, a Deep Sea controller, a soundproof enclosure, and is equipped for automatic transfer switch (ATS) operation. It includes a low-emission EUV (Stage V) version.

GDS 50 kVA Generator Set Models
Three-phase diesel generator series ranging from 27 to 94 kVA, soundproofed and equipped for automatic start-up. Filter by power output based on your installation.
What is a 50 kVA generator set?
A 50 kVA generator set is a high-power diesel unit (with an effective output of around 40 kW) consisting of an engine and an alternator, capable of providing an independent power supply to an industrial facility, a construction site, a farm, or a facility with high power consumption. kVA refers to apparent power; the actual effective power in kW is slightly lower, depending on the power factor.
It serves as the primary power source in areas not connected to the grid or as a backup that starts automatically in the event of a power outage. At this power rating, Genergy operates on a three-phase system (400/230 V) with a diesel engine running at 1,500 RPM for continuous and intensive use, features a soundproof enclosure, and, in the EUV version, is equipped with a Stage V low-emission engine for regulated areas.
How much power do you need?
Guideline. The exact power rating depends on the connected equipment, its startup peaks, and hours of use. Add up the power consumption and include a 20–30% margin. Tell us about your situation, and we’ll help you select the right equipment.
| Type of installation / use | Approximate power | GDS Models |

Frequently Asked Questions About the 50 kVA Generator Set
What can a 50 kVA generator power?
It is a high-power generator capable of supplying power to industrial facilities, construction sites, agricultural machinery, the hospitality industry, or high-consumption facilities, with multiple pieces of equipment running at the same time. The exact amount depends on power consumption and the startup peaks of motors and compressors.
How many kW is 50 kVA?
kVA represents apparent power, and kW represents useful active power; with a power factor of 0.8, about 50 kVA is equivalent to about 40 kW. When sizing a system, what matters is the actual power consumption (kW) of the installation.
What is the EUV (Stage V) version?
The GDS55T EUV is equipped with a low-emission engine that complies with European Stage V regulations, designed for use in areas with environmental restrictions, such as urban construction sites or regulated areas.
Why diesel at 1,500 RPM?
The diesel engine at 1,500 RPM operates at a lower speed: less vibration and wear, lower fuel consumption, and a longer service life. It is the ideal choice for continuous and intensive operation, which is common in industry.
Do the 50 kVA generator sets have an automatic start system (ATS)?
They are equipped for automatic startup in the event of a power outage via an ATS transfer switch, so they start up on their own during an outage and restore power within seconds.
Do I need more or less power?
For lower power ratings, consider the 20 kVA or 10 kVA generator sets; for industrial facilities with higher power consumption, consider the 100 kVA generator or the industrial series (up to 358 kVA).
Do you offer a warranty and technical support?
Yes. Genergy is a manufacturer that offers a 3-year comprehensive warranty (covering labor, travel, and replacement parts), its own after-sales service, and a network of distributors throughout Spain.
The recommended power ratings are approximate and depend on each installation. The ATS panel may not be included, depending on the model.
