What Is an Electric Generator, and Which One Do You Need?

An electric generator—also known as a power generator or electricity generator—converts fuel or stored energy into electricity in places where the power grid does not reach, or when the grid fails. Genergy It has been manufacturing generators since 2007, with a product line ranging from 1,100-watt portable units to 358-kVA industrial units.

In Genergy You’ll find four technologies in a single catalog: gasoline engines for everyday use, inverter generators for those who need quiet operation and clean power, diesel generators for continuous operation, and battery-powered stations for situations where combustion or noise is not allowed. You don’t need to know which is which: below, we’ll tell you—based on your situation—which technology is right for you and which product line to choose when buying your electric generator.

Continuous use · industrial

Many consecutive hours or support from a building

Whether the generator needs to run for 8-, 12-, or 24-hour shifts, or provide automatic power to a warehouse or a residential complex, the technology changes. This is where diesel generator sets come in: engines running at 1,500 rpm designed for continuous operation.

View diesel generator sets →
Noise is the problem

Residential development, terrace, or regulated campground

There are places where decibel levels matter more than power output. This is where silent or soundproof generators come in, designed to operate near neighbors or other tents.

View quiet generators →
No combustion, no noise

No engine, no gasoline, not a single decibel

Indoors, in a hospital, in a room with children sleeping nearby: to charge devices, tools, or small appliances without using fuel, the solution is a portable battery station that can be recharged from the power grid or via solar panels.

He moves around a lot

You're constantly loading and unloading it

From job sites to events, from the van to the garage: if the generator spends more time on the move than it does stationary, its weight and size matter just as much as its power. This is where portable generators come in.

High-Power Three-Phase

Three-phase motors and heavy machinery

Pumps, concrete mixers, large compressors: once you reach a certain power level, you need 400 V three-phase power. With gasoline-powered units, we can go up to 22.5 kVA with the Big Series; for higher power, we switch to diesel.

How to Choose the Power Rating of Your Electric Generator

The most common question people ask before buying an electric generator isn't "What technology?" but "How many watts?"

And the answer has two parts. The rated power is what the generator delivers continuously. The starting or peak power is what a motor—a refrigerator, a pump, a compressor—requires during the first second, which can be double or triple its normal consumption. A generator that handles your refrigerator just fine once it’s running may fall short if it can’t handle the peak demand of the compressor when it starts up.

To make sure you don't fall short: add up the watts of everything you want to use at the same time, identify the appliance with the most power-hungry motor on that list, and add a 25–30% margin to the total to cover its startup.

Power Consumption and Startup Peak of the Most Common Appliances
DeviceApproximate consumptionStart-up peak
LED Lighting (Spotlights)10 – 15 W—
Router + TV~150 W—
Refrigerator150 – 300 Wx2 – 3 at startup
Gas or diesel boiler150 – 300 Wx2 at startup
Microwave1.000 – 1.200 W—
Water pump or well pump750 – 1.500 Wx2 – 3 at startup
Small Air Conditioner1.000 – 1.500 Wx3 at startup

Typical reference values, not catalog figures Genergy: Each appliance lists its actual power on the label or in its technical specifications, and that is the figure you should add up. Complete guide: How much power does a home need from an electric generator?.

Why a Generator? Genergy

1.100 W – 358 kVA

The most comprehensive catalog in one place: from portable pocket-sized power stations to industrial generators, all under the same brand and with the same after-sales service.

Manufacturer

Genergy It designs and ensures the quality of its generators with its own technical team in Spain; it is not just an importer that simply puts its own label on the products.

3-Year Warranty

3 years for individuals and 1 year for businesses across the entire product line. You buy a generator for the day the power goes out: on that day, it matters who’s there to help.

SAT in Spain

In-house technical service and replacement parts throughout the country, without having to rely on an importer or an online marketplace to obtain a part.

THD <3 %

Clean power across the entire inverter range: safe power for sensitive electronics, battery chargers, and microprocessor-based equipment.

Since 2007

A Spanish brand with nearly two decades of experience specializing in generators, with a product line that has grown alongside its customers' needs.

When You DON'T Need a Generator

We'd rather let you know before you buy something you won't use.

If you just want to charge devices

Cell phone, laptop, a lamp, or a small camping cooler: one battery station is more than enough. It’s quiet, maintenance-free, and doesn’t rely on fuel. See the “No Combustion, No Noise” section above.

If you need a continuous supply

For a home or business that can never be without power, the long-term solution is the power grid or a permanent installation—not a portable generator that needs to be refueled, monitored, and maintained. A generator is a backup, not a substitute for the grid.

What is the best home generator?

The one that combines an electric start, a large fuel tank, and—if you won't be home—automatic restart in the event of a power outage. That's what the Cube line offers, with its ATS and SOL models. See Cube home generators →

Is it legal to have a generator at home?

Yes. It must always be used outdoors in a well-ventilated area, in compliance with your municipality’s noise ordinance, and if it is connected to the home’s electrical panel, it must be installed by an electrician using a switch or an ATS panel—never plugged directly into a household outlet.

What kind of electric generator do I need for a house?

For home backup, a gasoline generator from the Cube line; if noise is an issue in your neighborhood, a quiet inverter; and if you already have solar panels, the SOL version. See generators at Cube →

What is the difference between a generator and a generator set?

In everyday use, “generator” refers to lightweight gasoline or inverter-based units, while “power generator set” refers to higher-powered diesel units designed for continuous operation, although technically both are machines that generate electricity. We explain this in detail in the article “The Difference Between a Generator and a Power Generator Set.”

How much power does an electric generator consume?

It depends on the power output, load, and technology: between 0.3 and 2 liters per hour for gasoline or diesel models, and no fuel consumption for battery-powered models. Complete guide: How much fuel do gasoline and diesel generators consume?

How long does an electric generator last?

With basic maintenance, a generator Genergy If properly maintained, it provides several thousand hours of service; the exact figure depends on usage, the load it carries, and the technology. Details at How long does an electric generator last?.

What kind of maintenance does an electric generator need?

For combustion models: change the oil regularly, keep the air filter clean, and start it up occasionally if it's in storage. Battery-powered models require no mechanical maintenance. See " How Long Does an Electric Generator Last?" for more details.

Can a generator be used with solar panels?

Yes. The SOL versions of the Cube line are designed to serve as a backup for a photovoltaic system and start up automatically when the solar battery level drops. The Zero Emission portable stations can also be recharged directly using solar panels.

How much does an electric generator cost?

The price of an electric generator depends on its power output, technology (gasoline, inverter, diesel, or battery), and model (ATS, SOL, three-phase, etc.). Tell us what you need to power via the contact form, and we'll let you know the exact model and price.

Single-phase or three-phase?

Single-phase (230 V) power is sufficient for homes and most construction sites and household equipment. Three-phase (400 V) power is required for industrial motors, large pumps, or concrete mixers: gasoline-powered models go up to the Big Series, and diesel models go up to 358 kVA in the GDS series.

How do you connect a generator to a home?

Using a manual switch or an automatic transfer switch (ATS), which must always be installed by an electrician—never plugged directly into a household outlet. A step-by-step guide to connecting a generator to a house.

Generally good experience. My issue is with delivery times. Website claim is 2--3 business days whereas actual is 5-7 business days. Also when ringing the courier company CBL and requesting info in English they just hung up the phone on a number of calls. They do not reflect the courtesy shown by Genergy. This was down to Daniel Perez. He showed a level of professionalism, efficiency and communication which is a treasure to your company. Thank you Daniel.
