Cube Generators for Home Use: Automatic Backup and Easy to Move

The Cube series consists of generators Genergy Designed for home use: 2,800 to 7,000 W, with a Zero Gravity frame, up to 17 hours of runtime, and ATS and SOL versions that start up automatically. 3-year warranty.

What is the product line? Cube and who it's for

Cube It's a home power generator: to keep your home's lights, refrigerator, and water heater running when the power goes out, and to back up a solar system when the batteries run low. It's also ideal for country homes and second homes not connected to the power grid.

Five models with electric start, a fuel tank capacity of up to 28 liters, and the frame Zero Gravity, which balances the entire weight on a single point so that one person can move it. The versions ATS start up on their own when the power goes out; the versions SOL, when your solar batteries run out. No one has to be home. Everyone has a car Euro V, copper alternator and regulation SVR, which can handle the startup surges from a refrigerator, pump, or air conditioner.

  • 2,800–7,000 W; fivemodels, eight variants

  • Up to 17.5 hwith a 28-liter tankat 25% capacity

Frequently Asked Questions About Home Generators

How much power does a generator need to have for a house?

Between 3,000 and 7,000 W, depending on what you want to power: 3,000–4,000 W for essentials (refrigerator, lights, water heater, router) and 5,500–7,000 W for almost the entire house without air conditioning. Add up the watts and add 25% to account for startup peaks. Gorbea and Estrela cover the first one; Aneto and Mulhacén, the second one.

What is the best gasoline-powered generator for home use?

One with an electric starter, a large fuel tank, and—if you won't be there—an automatic starter. Mulhacén 7.000 W ATS Put the three pieces together and add the frame Zero Gravity so that one person can move it.

Is it legal to have a generator at home?

Yes. It should always be used outdoors in a well-ventilated area, away from windows (exhaust fumes), in compliance with your municipality’s noise ordinance, and, if you connect it to the home’s electrical panel, do so using a switch or panel. ATS installed by an electrician; never plugged into a household outlet.

Which generator is suitable or recommended for a home?

For occasional haircuts, Gorbea 2,800 W or Moncayo 4,500 W. For a whole house or a second home, Mulhacén 7,000 W with ATS. If you have solar panels, the version SOL It starts on its own when the batteries run low.

How exactly does the version work? ATS?

The built-in transfer switch detects a power outage; the generator starts up on its own in just a few seconds and powers the house. When power is restored, it switches back to the utility grid and shuts down. An electrician connects the system to the home's electrical panel.

And what about the version SOL, what does it do?

It connects to the inverter in your solar power system and starts up only when the batteries drop below the level you set; it shuts down when they recharge. In Moncayo SOL and Mulhacén SOL It is compatible with inverters Genergy; inverter models (Creta SOL) do accept any investor. Guide: How to Connect a Generator to a Solar Inverter.

Can I move it by myself?

Yes. It weighs between 60 and 90 kg depending on the model, but the frame Zero Gravity Distribute the weight along the axle, and the handlebars unfold: you can move it with one hand, just like a suitcase.

How long does the deposit last?

Does it work for the air conditioner?

A 3,500 BTU split system consumes about 1,200 W but starts up at about 3,000 W. With Aneto or Mulhacén Yes, as long as you don't turn everything on at once; the control SVR absorbs that peak.

Is it too loud to have it in the yard?

Between 64 and 74 dB at 7 meters, depending on the model—similar to a conventional generator. If your neighbors are very close by or you also want to use it for camping, the quiet inverters operate at 52–58 dB.

What happens if gasoline has been sitting in the tank for months?

It deteriorates. If the generator is going to be idle for a long time, drain it or run it for 15 minutes once a month. If you want to forget about it, the line Natura It runs on propane, which doesn't expire.

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-made and high-quality, starts right up, and the noise level is pretty standard for 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 they delivered it with oil already in it and ready to use—even though they didn’t have to, since at the big retailers, they don’t even bother to open the box for you to see 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 solution that was fast, effective, and on par with what you’d expect from a mature, well-established team. Their service was direct, transparent, and straightforward—no evasiveness or automated responses 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.
