Buying Guide to Get the Best 12,000 Watt Generator

Searching out the best 12000 watt portable generators from the market isn’t easy. Because you’ll be bombarded with thousands of choices if you go around the market to get a quality power backup system for your house. This is where the quality inspection guidelines come up. We have researched the products and found out key issues that you should always keep in mind before buying a generator.

Let’s look at some of those criteria that you must adhere to before purchase.

Rated VS Peak Watt

Most of the time, you’d notice the manufacturers are mentioning two specific numbers, one for peak and another for rated. Here is what you should understand. The peak electricity output is something that you get for a little while; it won’t last long. It is mainly used to kick-start certain electrical equipment, which needs an immense amount of power to start.

The rated wattage, on the other hand, is the continuous supply of electric output. If you want a 12,000-watt generator always to run a large 3 or 4 bedroom house, then try getting power backups that promise you 12k Rated wattage instead of a peak.

Runtime

Outages are frequent during hurricanes and other large-scale natural disasters. Sometimes the damaged power lines take days to get fixed. This can be a serious issue as we are heavily dependent on electricity in almost all our daily activities. That is why the more runtime you get, the better it is for you.

If you get a device that provides 11-12 horse power of runtime with 50% load, we think you can go 2 days with the minimum load easily, and the grid should be back up by that time.

We also recommend that you inspect and find generators with large fuel tanks and lower consumption rates. These two aspects have to go hand in hand, and a large tank will provide more fuel capacity while a low fuel consumption rate will eat up less fuel and deliver more power. It will increase your machine runtime and lower the cost that is spent behind it.

Fuel Type

What kind of fuel is supported is another key aspect while you’re looking for 12000-watt generators. It can either have single fuel support or double. It is always better to go for devices that support multiple fuels. It will help if one sort of fuel is not unavailable, you can easily go for the other one and vice versa. Similarly, it is cost-effective, too, as you can choose the cheaper one among the two as your primary propellant.

Noise Production

Noise is a serious issue if you’re speaking about generators. Because of this, they have a measurement system in place, which gives you some understanding regarding the sound each machine would produce. This is called the decibel rating and presented with ‘DB’ behind the number.

So, your goal would be to get the generator that has the lowest decibel rating. In that way, you will get generators with lower noise pollution.

Weight

Weight is perhaps the awful thing about these powerful devices. Most of the generators mentioned are heavy. So, better it is for you to go for one that is the least heavy. It will make transportation easier.

Portable Attachments

As generators at this size and scale are bound to be weighty, they should have attachments that can make movements easier. Most of the machines discussed here have some portability features such as wheel kits and handles. But we’re looking for quality in these particular instruments.

For example, it is always best to have wheels that never go flat. So, find the ones with never-flat wheel kits, which will ensure your safety from any unnecessary issues later on. Best if you can get rubber wheels instead of plastic, as it may not give you the traction required to pull that heavy thing.

Finally, make sure the handles have some easy gripping technique, whether plastic or rubber. If you make sure of these couple of things, it would be easier for you to move this heavy machinery from one place to another.

Warranty

It is best to buy generators with warranty offers. As being electric equipment, it can be prone to wear and tear. Further, tiny issues in internal mechanics can render it not working. You then will have to go through a strenuous servicing process that will take your time, cause added worry, and cost you money.

Warranty, in this case, backs you up.

Warranty procedures can vary from product to product. Some offer full warranty, and some offer limited parts warranty. Some products have warranty features, but the manufacturer perhaps did not mention them. We’d recommend you discuss the actual warranty terms and conditions with the manufacturer to avoid future disagreements.

Control Panel

The Control panel is the area where the outlets are situated. Many control panel has unique outlets yet lacks in regular AC 120 outlets. Try getting generators that have more regular AC 120 outlets. The fuel gauge is important too as it lets you monitor the fuel level and helps you decide whether you should buy backup fuel. USB and Twist Lock outlets are essential as well. So make sure you have all these features on the control panel.

These are all the requirements that your generators should fulfill. Make sure they have these particular features installed in them. We are positive that you’d be able to purchase a quality piece of equipment following the guidelines mentioned above.
