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 electric generators have a great lineup that caters to different needs of customers. Some people in the market for a generator 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 generators from various capacity ranges. We have classified them in four main categories: 1,000 – 1,500 watts, 2,00 – 2,500 watts, 8,000 – 8,500 watts, and 9,000 – 9,500 watts.

How does an electric generator 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 generators 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 Class Generators

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

On the other hand, industrial-class generators have a capacity that ranges from 20,000 watts to 3,000,000 watts. Businesses typically require higher wattage 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 generator: shopping malls, living centers, manufacturing sites, office buildings, and educational centers.

What capacity do you need?

The wattage capacity that you will be needing depends on a few factors. First, you will have to consider how many appliances will be needing power from the generator. If you plan to run basic appliances such as a few ceiling lights and your refrigerator, you might be able to work with a small generator. However, if you will be powering appliances that consume a bit more power, such as air conditioners and heaters, you will need a generator with a larger capacity. Second, you should look into the maximum wattage of all the devices you plan to use with your generator. Once you have this value, look for a generator that can handle the maximum surge watts and running watts of these appliances and devices. You will know more about running watts and surge watts in the following sections. Lastly, find out the length of time you will be using the generator. How long a generator 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 a generator. Consult with a licensed electrician for better knowledge and understanding of which capacity you will be needing.

Surge Watts and Running Watts on Generators

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

When a device or appliance initially starts or runs, it requires a surge of energy to kickstart the motor. The wattage it requires is called the surge watts, which are typically higher than the running watts 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 watts when running and powered by a generator.

Below is a table of the most common appliances you can find at home and their corresponding surge watts 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 Watts Running Watts
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 watt capacity, which means a 1,200-watt generator can provide about 1,080 watts of running watts capacity and about 1,200 watts of surge watts capacity.

How to determine the capacity you need?

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

List the devices to power with an electric generator

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 watts and running watts for each device

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

Sum the running watts

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

Determine the device with the highest starting watts

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

Add the highest starting watt with the running watts total

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