Best 1000, 2000, 5500, 8000, 9000 watt generators

In the past year, there has been an increase in the demand for a consistent electricity supply at home. Since several companies and businesses have shifted to a work from home setup, most employees of these companies need to have interrupted power to meet their deliverables on time. Some people working from home cannot afford to miss that important virtual meeting with the client, pushing them to look for backup power options.

With the increasing number of brands that manufacture and sell electric generators, it has become more accessible and affordable. Several years ago, owning one cost so much that it does not make sense to most consumers. Today, brands that sell these machines have a great lineup that caters to different needs of customers. Some people in the market might only need 2,200 watts of capacity, so getting one that is way more than their needs may not make sense and could be expensive long term.

In this article, we will be discussing electric options from various capacity ranges. We have classified them in four main categories: 1,000 – 1,500, 2,00 – 2,500, 8,000 – 8,500, and 9,000 – 9,500 watts.

How does it work?

Most people know that electric generators provide electricity. What most people do not know is how it does the work. These machines do not create electricity. They convert energy, usually chemical or mechanical, into electrical energy.

Electric ones observe the electromagnetic induction principle, wherein a copper coil rapidly rotates in the poles of a horseshoe type magnet. The armature connects to a shaft, which is the source of mechanical energy. Finally, the mechanical energy it requires comes from engines on petrol, natural gas, diesel, etc., or via renewable energy sources such as solar-powered turbine, wind turbine, water turbine, etc.

The magnetic field gets interrupted when the coil rotates, resulting in an electric current flowing inside it. We understand that this could be a lot to take in for most people, so you may want to take a look at some of the best mini metal lathes available in the market.

Industrial Class and Residential Classes

The two main classes are industrial and residential. By now, you may already have an idea of which class you need. For users who intend to use theirs at home, you need a residential-class one. They come as either a stationary standby ones or a portable model. Units belonging to this class typically have a capacity of 2,000 watts or less for recreational units or up to 50,000 for standby units.

On the other hand, industrial-class models have a capacity that ranges from 20,000 to 3,000,000 watts. Businesses typically require higher capacities because of the number of devices it needs to supply power. Most of these units use a three-phase motor to deliver higher results. The following are some offices/businesses that may require an industrial-class model: shopping malls, living centers, manufacturing sites, office buildings, and educational centers.

What capacity do you need?

The capacity that you will be needing depends on a few factors. First, you will have to consider how many appliances will be needing power. If you plan to run basic appliances such as a few ceiling lights and your refrigerator, you might be able to work with a smaller model. However, if you will be powering appliances that consume a bit more power, such as air conditioners and heaters, you will need one with a larger capacity. Second, you should look into the maximum wattage of all the devices you plan to use. Once you have this value, look for one that can handle the maximum surge and running watts of these appliances and devices. You will learn more about these two things in the following sections. Lastly, find out the length of time you will be using the generator. How long it can run will depend on a few factors, such as fuel consumption, power, and tank size. Check with the manufacturer and model for these specifications.

These are only some of the factors to consider when picking one. Consult with a licensed electrician for better knowledge and understanding of which capacity you will be needing if you are not comfortable determining your requirements after reading this article. Ultimately, it comes down to your requirements and how many different appliances you are hoping to be able to run in case there’s an outage, why a household hoping to keep all the lights and various electrical devices going, will require a more powerful piece of equipment. However, if on the other hand you are simply hoping to be able to keep your refrigerator and freezer going if there’s an outage, your needs are very different as well.

Surge and Running Watts

As mentioned in the previous section, there are two important things to consider in terms of the watts of appliances: surge and running.

When a device or appliance initially starts or runs, it requires a surge of energy to kickstart the motor. What it requires is called the surge watts, which are typically higher than the running requirements for a device or appliance. On the other hand, the running watts is the value required for a device when running. For example, a 60 watts light bulb will consume 60 when running.

Below is a table of the most common appliances you can find at home and their corresponding surge and running watts. Take note it may vary depending on the manufacturer and model. It is still best practice to check the specifications sheet before purchasing.

Device Type Surge/Starting Running
Refrigerator 1200 800
Water Heater 0 4000
Electric Stove Burner 0 1500-2500
12,000 BTU window aircon 1800 1200
Garage door opener 600 480
60-watt light bulb 0 60
Microwave 800 625

When looking at the table above, some devices do not require surge watts because there are no motors that require electricity to start. If you refer to the table above, the devices that do not require surge watts are the water heater, light bulb, and electric stove burner element.

In most cases, the running watt is around 90% of the generator’s surge capacity, which means a 1,200-rated model can provide about 1,080 watts of capacity and about 1,200 of surge capacity.

How to determine the capacity you need?

Without any guide, determining the capacity you need can seem overwhelming. With these five easy steps, you can get an estimate on how much capacity you need.

List the devices to needed to be powered.

Let’s assume that you want to power one stove burner, air conditioner, a few light bulbs, and refrigerator with a generator. Being able to use these devices in case of power interruption ensures your comfort and safety.

Specify the surge and running watts for each device

One stove burner requires about 0 surge and 2,500 running watts. A refrigerator typically needs 1,200 surge and 800 running. A 35-watt light bulb requires 0 surge and 35 running. Lastly, an air conditioner needs 1,800 surge and 1,200 running.

Sum the requirements

The sum of the running watts is 4,535 in this example.

Determine the device with the highest starting requirements.

With the devices listed in step one, the air conditioner requires the highest starting watt at 1,800.

Add the highest starting with the running total.

Let us add the numbers together, which is 4,535, to the highest starting of 1,800. The sum of these two is 6,335 watts, which is the total requirement. With that said, you need one with a surge capacity of at least 6,335.

There are several available models with varying capacities in the market today, so picking the right one for your needs can be tricky. Keep in mind that this is only a guide and that you should consult a licensed electrician before purchasing a unit.

Below are some of the most common capacities available in the market. You can go through each one or use your browser’s search functionality to skip to the part that interests you. Before proceeding, you need to keep in mind that the cables you will be using come in different sizes. You can refer to 20 – 60 amp wires and 70 – 600 amp wires here.

1,000 – 1,500

Some brands that offer models in the 1,000 – 1,500 watts range are Sportsman, Powerpro, Yamaha, and Honda.

The first one worth mentioning is the Sportsman Gen1000I gas-powered model. This model offers 1,000 surge and 800 running watts. It has a 1.3 HP 4-Stroke gasoline engine, which can power through your devices. The engine is rated to run for 6.3 hours at 50% load. In terms of fuel capacity, it comes with a 1.7-gallon fuel tank. When planning to use it at a high altitude, we do not recommend using it 3,000 ft. above sea level. The Sportsman Gen1000I may not work correctly at this height. For best performance and output results, use this generator below 3,000 ft. For any warranty claims, the unit comes with a one-year limited warranty.

The Honda EU1000I 120V model is ideal for small power tools, electric fans, lights, televisions, and other small appliances at home. Honda claims this product is super quiet with a noise level of only 50 dB at the rated load and only 42 dB at 1/4 load. The Honda GXH50, which is the engine that powers the EU1000I, can run up to 6.8 hours on a 0.55-gallon of fuel. Weighing at only 29 lbs, it is portable and lightweight.

The next one is the Honda EX1000. This specific model works great for powering fans, small power tools, laptops, mobile phones, and lights. Using a three-prong AC outlet, you can plug two power wires into the side of the unit. The 0.82-gallon gas fuel tank allows for up to 8 hours of use. The EX1000 does not get loud with only a 64 dB noise level. In case of voltage overload, the AC circuit breaker automatically stops the engine from running to prevent damage from happening. This model can handle up to 2,000 watts. It can safely handle less as well, such as 900 or 1,000, as you can see is closer to what you will need if you are powering something like a fridge.

2,000 – 2,500

Some notable brands in the 2,000 to 2,500 watts range are Champion, Predator, Westinghouse, Pulsar, Workzone, Honda, Wen, and Ryobi. But in this section, we will take a closer look at the Honda EU2000I and the Wen 56200I.

The Honda EU2000I 120V inverter generator is ideal for televisions, DVD players, satellites, coffee pots, refrigerators, and other small household appliances. To provide stable, consistent power to the connected devices, the EU2000I uses inverter technology. At only 48 to 57 dB, this unit is super quiet. It is ideal for supplemental RV power, camping, and other activities that require minimal noise. Its weight of only about 47 lbs. makes it very portable and lightweight.

On the other hand, the Wen 56200I inverter generator is a close competitor of the Honda EU2000I. It is great for use in construction sites and campgrounds. It generates a running power of 1,600 and a surge rating of 2,000. One of the notable selling points of the Wen 56200I is its low harmonic distortion. At under 0.3% at no load and 1.2% at full load, it is safe to use tablets, cellphones, laptops, and other electronic gadgets with it. Should you need more than 2,000 in the future, you can link two Wen units using the Wen Parallel Kit.

8,000 – 8,500

The 8,000 to 8,500 watts range belongs to the higher end of the spectrum. Ones rated at this capacity often support more than one appliance of the same type running together. Depending on the size of the house, a model in this range may work well for you. Some notable brands to consider are Briggs and Stratton, Ridgid, Honda, Generac, Troybilt, Gentron, and Champion. If you think 8,500 is not enough, then you may want to consider a model in the 9,000 – 9,500 range.
