What Is the S Version and Who Is It For?

An S version—what the industry calls the “rental series”—is the same generator Genergy with safety features designed for equipment that isn't always operated by the same person: a 30 mA ground-fault circuit interrupter and waterproof outlets IP67 Standard on all sixteen models. Complies with European safety regulations for factory equipment.

It is designed for rental companies (The generator is sent out to a different customer each week and has to come back in working order), so that public works and bid documents (which require a 30 mA differential current and IP protection) and for companies with their own fleets (construction companies, installation companies, city governments, civil protection agencies). It is available in three performance ranges: Professional (2,800 W–10 kVA, to fit in the van), BFT Professional (large tank for long trips) and Big Series Generator (9–18 kW, three-phase). Euro V engine, copper alternator, and regulation SVR in all of them.

What's different in the S version?

30 mA differential

Standard protection against indirect contact, built into the generator itself, is included in all sixteen models. This is a requirement of public works specifications and helps prevent accidents when the user is not an electrician.

Tomas IP67

Dust-proof and resistant to temporary submersion, even after sixteen uses. Rain, mud, and hoses used for cleaning between rentals don't affect the panel.

Manual start without a battery, on the Profesional S

A dead battery is a common fleet problem: the generator returns from a rental, sits idle for weeks, and then won't start. The seven Profesional S They do not require a battery and are pull-started. The five BFT models and the four Big Series models retain the electric start, because their weight and power make it the preferred option for everyday use.

Emergency Shutdown (Big Series)

The four Big Series S They include an emergency shutdown feature, in addition to the differential, for three-phase machinery on construction sites.

Chassis and wheels for loading and unloading

Reinforced tubular frame with integrated wheels and handles (solid, swivel, and with brakes on Big Series) for daily loading and unloading using a van and trailer without damaging the equipment.

Cable Clips

They prevent an extension cord from being yanked and breaking the panel or outlet: the second most common malfunction in equipment that changes hands frequently.

Everything else is the same

Euro V engine, copper alternator, regulation SVR, filter Typhonic (Professional and BFT), with integrated wheels and handlebars. The S version doesn't compromise on performance; it adds protective features.

What a fleet needs, and which S version meets those needs

Daily Rentals

The “all-day” trip that doesn’t come back because of a lack of gas

The customer rents the unit for a day and doesn't want to refuel it. The BFT models, which have the largest fuel tanks in the catalog, are the gold standard for rentals: the Urkiola-S 5,500 W and the Angliru-S 8,000 W.

Event Rentals

Weddings, fairs, food trucks

Average power output, long hours, and a customer who knows nothing about generators: Urkiola-S or Ancares-S (230/400 V) if there’s a kitchen or air conditioning. For events with a nearby audience, supplement the fleet with quiet inverters.

Rental for Construction Projects

Tools and a concrete mixer at the construction site

Dust, bumps, and daily commuting: Profesional S with filter Typhonic and built-in wheels. Navacerrada-S 5.500 W and Astún-S 7.000 W these are the most frequently rotated items; Candanchú-S and Bentayga-S when they request 400 V.

High-Power Rental

The “big one” that doesn’t need a truck

Three-phase, 11.5 to 22.5 kVA, four-wheeled, fits in a large van or light trailer: Izoard-S 15 kW and Stelvio-S 18 kW. It covers the range that previously required renting a diesel generator with special transportation.

Public Works

What the specifications require

30 mA residual current protection, IP rating, CE marking, and Euro V motor. All S versions come standard with these features, without the need for external control panels or modifications. Technical documentation and declarations of conformity are available for your records.

In-house fleet

Construction companies, installation companies, city governments, civil protection agencies

Standardized equipment in three power ratings, with the same replacement parts and maintenance requirements for the entire fleet. One model per range (for example Jaca-S, Astún-S, Angliru-S) simplifies spare parts and training.

Made for many hands and many hours

A fleet generator pays for itself through the rental income it generates without breaking down. These are the things that matter at the end of the year.

100% Copper Alternator

It withstands continuous operation better than aluminum: less heat buildup, longer service life. It is the part that determines a generator’s lifespan.

Filter Typhonic

In Profesional S and BFT: removes heavy debris before it reaches the motor. Less wear and tear for customers who don't clean the filter.

Protections That Prevent Claims

30 mA differential and IP67 At the sixteen: fewer incidents involving users who aren't electricians, and fewer disputes over refunds.

No battery in the Profesional S models

The Manual Start at Seven Profesional S Replace the dead battery between rentals: the equipment is returned, cleaned, stored, and started up again weeks later.

Spare Parts and Technical Support in Spain

Filters, spark plugs, alternators, dashboards, and sockets specific to Genergy. A generator that is repaired is put back into service; one without replacement parts is taken out of service.

Standardized Fleet

The same parts and the same maintenance across all three product lines. One model per power range simplifies spare parts, training, and service procedures.

Frequently Asked Questions About the S Models

¿Genergy Do you rent generators?

No. Genergy It is a manufacturer that produces and sells its own equipment; many rental companies and distributors work with its generators Genergy. If you need to rent one, check our dealer network or write to us, and we'll direct you to the nearest one.

What exactly is the S version?

The same generator with a standard 30 mA ground fault circuit interrupter and outlets IP67 in the sixteen references. The seven Profesional S They add manual start without a battery and the four Big Series S

Are all S versions manual start-up models?

No. All seven are manually started and don't have a battery. Profesional S: Veleta-S, Jaca-S, Panticosa-S, Navacerrada-S, Astún-S, Candanchú-S and Bentayga-S. The five BFTs and the four Big Series They have an electric starter, which is more practical for everyday use at those weight and power levels.

What are the benefits of manual starting in a fleet?

The battery never runs down. The generator comes back from the rental company, sits idle for weeks, and still starts right up. That's why the Profesional S, which are used most frequently and spend the most time in storage, do not require it. For everyday personal use, the standard version with an electric starter is more convenient.

Does it meet the requirements of the public works specifications?

Yes: 30 mA residual current device, IP-rated protection on the outlets, CE marking, and a Euro V-compliant motor—all factory-installed. We have technical data sheets and declarations of conformity for the file.

Which S models are the most popular at a rental company?

For construction, Navacerrada-S (5,500 W) and Astún-S (7,000 W). For events and long days, Urkiola-S (5,500 W, 27 L) and Angliru-S (8,000 W). For three-phase, Candanchú-S and Bentayga-S and, at high power, Izoard-S and Stelvio-S.

What is the difference between Profesional S And what about BFT?

Same mechanism; the BFT has a tank capacity of 14 to 27 L, compared to 2.6 to 6 L for Profesional S, and electric start. If your customer rents it for the entire day without refueling, BFT; if they work by the hour and transport it frequently, Profesional S.

How long does a generator last in a rental fleet?

As long as you follow the maintenance schedule in the manual (oil change every 50–100 hours, filter, spark plug), this equipment will last for years. The copper alternator and the filter Typhonic are what extend the service life of a fleet the most.

Are replacement parts and technical support available to maintain the fleet?

Yes: original pieces by Genergy (filters, spark plugs, alternators, dashboards, sockets) and after-sales service in Spain. Standardizing the fleet to a small number of part numbers simplifies spare parts inventory.

Are there volume-based pricing or reseller terms?

Yes. Please contact us using the contact form, specifying the product codes and quantities, or check the list of authorized distributors.

Can I customize the fleet (color, lettering)?

Please contact us using the contact form: pricing depends on specifications and quantity.

What kind of warranty do you offer to businesses?

I recently purchased a Limited 7000 generator. I contacted the company by email to ask a few questions, and they responded immediately. Plus, they’re going to replace the industrial outlet adapter in a couple of days. GREAT AFTER-SALES SERVICE—for once, what they say is true; that’s what I call service. As for the generator, it looks well-built and high-quality, starts right up, and the noise level is about what you’d expect from a gasoline-powered generator—it’s a good machine. For now, I’m giving Genergy 5 stars.

I bought the 3000 diesel generator. They tested it at the factory before shipping it to me and delivered it with oil already in it and ready to use—even though they didn’t have to, since with large retailers, they don’t even bother to open the box for you to inspect it. Once tested, it works very well, and I have no complaints. The customer service is excellent. I called several times to get more information—and, by the way, to make sure it wasn’t one of those scams that are so common in online sales these days—and I can assure you that this is a trustworthy company from which I’ll make future purchases. Thank you very much for everything.

Definitely a trustworthy company. I had a minor issue with a generator, and they resolved it within 24 hours. They responded to my email incredibly quickly and provided a fast, effective solution—the kind you’d expect from a mature, well-established team. Their communication was direct, transparent, and straightforward, with no evasive tactics or automated replies that lead nowhere. By the way, the generator is a Genergy 5000, and it works like a charm—well-designed, compact, and reliable. I use it almost exclusively to power a 1.5 HP well pump. It’s definitely a great choice, and I highly recommend it.
