Essential Considerations before Buying a 12000-watt Generator

Having gone through the best quality 12000-watt portable generator reviews, you might have noticed that it might be a tough choice picking from hundreds of such products that are available for sale.
However, market saturation shouldn’t pose any purchasing problems if you understand the essential features of the item you are looking for, and that’s why I have prepared this section to ease your purchase hassle. The section entails a brief look at the ideal features to consider during the 12000-watt generator purchase.

Transfer Switch

It offers the utmost safety when using a generator as your backup plan. It also bolsters your powering ability and protects your generator from damage. You can choose between a manual and automated transfer switch, although the automatic one is slightly expensive.

Noise

Running the generator at home or in a busy office might make you realize how noisy some machines can be. Fortunately, there are quite quiet generators that produce as low as 55 dB at half-load. Such devices are the ideal choices to consider. However, a 70 dB sound might also be tolerable, as this is in the range of a normal conversation.

Upkeep Needs

A generator is a machine that requires regular checks to run ideally. One important factor you should always check is the oil level, although this has been simplified by the automatic shutdown feature that’s incorporated in most devices. All in all, check the fuel level and keep it clean. Replace the filters with time.

Local Laws

Are there regulations prohibiting the use of generators in your state? Well, understand the rules of the land, as some states might consider your machine as a sound or air pollutant.


FAQ About 12,000-watt Portable Generators

There can’t be too much knowledge. Especially, when you’re looking for such a complicated tool as a portable 12K watt generator. Here are quick answers to some of the most frequent and reasonable questions.

How many home appliances can I connect to a 12,000-watt generator?

With such a voluminous amount of power, you can start and run heavy-duty industrial appliances that usually have the same starting and running wattage. 12,000 watts is enough to run 3-4 power tools simultaneously and without the need to turn any of them off to launch another one. With an average run time of 5 to 10 hours, such a generator is perfect for a variety of uses on remote construction sites.

This running wattage is also considered high enough for electricity shutoff emergencies. Using a transfer switch or an appropriate inlet box, you can use a 12,000-watt generator to launch and run the essential home appliances, including a refrigerator (approx. 1600 watts), lights (100 – 500 watts), a microwave oven (1500-2000 watts), a flatscreen TV (150-300 watts), a desktop PC (150-800 watt), and some other devices.

How long will a 12,000-watt generator run?

It’s quite difficult to make precise calculations on how long a generator will run as it depends on a wide range of factors, including the load, tank volume, engine brand, and even climate. The approximate runtime for the vast majority of 12K-watt generators at 50% load is from 8 to 12 hours. At 100% load, the tank may run low in 4-7 hours. If you want to calculate the runtime more or less precisely, you should divide the gas/propane tank capacity (gallons) by the declared hourly fuel consumption (gallons/hour).

The important thing to remember is not to keep the generator running until the fuel runs out. Gas-powered machinery needs regular rest and works alteration to avoid quick wear off and overheating. While this is a general rule, some generator models are explicitly designed for the continuous workload. In this case, you will find the manufacturer’s permission to run the tool without interruptions. In other cases, you should give them time to rest after every 4-5 hours of uninterrupted work.

Propane-powered models let you connect tanks of different sizes to the generator, which theoretically means longer runtime. You should keep following the rule and stop the engine regularly unless the opposite is provided for the particular generator model.

How much does a 12,000-watt generator cost?

The cost of a 12,000-watt generator depends on a variety of factors. They include:

  • The power and type of the motor – the higher it is, the more expensive a tool is. Hybrid models are also generally more expensive than average gas-powered ones;
  • Starter type – most generators come with an average pull-start feature. The price can be a bit higher if a pull start part is made with a unique technology that makes starting the engine easier. If a tool comes with an electric start feature, be ready to pay a significantly higher price. It can be from $1800 to $2,800, but the feature is really worth it. Finally, some generators include both starter options and a remote start controller;
  • Gas tank size – the bigger it is, the more the tool costs;
  • The number of ports – the more you want, the more you pay;
  • Extra features – this aspect can affect the price, but not necessarily as some small or new brands try to attract buyers’ attention by offering extras without rising the cost;
  • Brand – some brands have the reputation as industry leaders, innovators, and quality benchmarks, which gives them the right to set higher prices for quality and service.

Will a 12,000-watt generator power the entire house?

Yes, such wattage is enough to power a house via an appropriate transfer switch or an inlet box. However, you should be careful and turn off every appliance that isn’t necessary to maintain the essential parts of your house. Unlike industrial tools, many domestic appliances have a higher starting wattage. It means that you have to find the actual figures for each device and make a reference table of starting and running wattages. Hang it somewhere everyone sees it and make sure to instruct your family members on how to connect and run appliances when the house is powered by a generator. Your house wiring must be prepared for the generator power supply, so make sure to call a master to adjust and test-run the system.


Wrap Up

Conclusively, you might have gone through the reviews and saw OHV engines and wondered whether it’s an essential consideration feature. Well, Overhead Valve engines are more efficient and reliable, so why not go for them? Away from that, you must have seen that most generators have an electric start.

What you never saw in all is the upkeep-free battery, which ensures your machine never fails to start. So, go for the machine with an up-keep-free battery. Low oil levels cause engine damage, and that’s why almost all generators under review have an automatic low oil shutdown feature.

Finally, load protection and automated voltage regulators are essential as they protect your appliances from damage resulting from high voltage. So, are you wondering if there are other essential consideration features during the generator purchase? Well, you will get more assistance if you share your buying concerns with me.

  1. Wylin_908: I bought a DuroMax generator for building a house and so that later it would remain as a backup in case of a power outage. The tank of this 12000 watt generator is large and can be operated for a long time without interruption. Now the generator is used as a backup power source. It is especially useful in the cold season. It’s easy to use, that’s why I taught all family members to use it.

  2. Hello, Ronnie! Thank you for the review. Finally, I know something about generators. Could you tell me please which generator is compact to use in RV?

    • Hello, thanks for reading my blog and happy to help! The most compact portable generator in this collection is the Pulsar 12,000W Dual Fuel. It is small in size and does not take up much space. At the same time, it contains a lot of fuel due to the large fuel tank. It starts up quickly and runs for a long time. If compactness is important to you, this is the best option.

    Thank you very much for this review. However, I wish you had included the quality of the output power (THD). Variations in cost, noise, etc. are unimportant if the generator ends up frying the electronics I’m using to receive information during a natural disaster.

  4. HI Ronnie
    I like the Rainier r12000df, because of its quietness. But will it do well on my 240 volt equipment. Thanks
