Must Know: What Size Inverter Needs To Run A Circular Saw?

Last Updated On June 25, 2023

Circular saws are undoubtedly famous tools for woodworking and home improvement. But, since most home runs on AC power, an inverter becomes mandatory to use a circular saw. So, what size inverter needs to run a circular saw?

Generally, 2000-4000 wattage inverters are perfectly suitable for running a circular saw. However, still, it depends on various factors like device voltage and ampere. Medium to large-size inverters provide the best services to run a circular saw.

Here you’ll get a wholesome detail about various sizes and types of the inverter. You’ll learn some factors that are essential in choosing your inverter size. Besides, our step-by-step guide helps you a lot to find out your device inverter.

Advantages of Having An Inverter in A Circular Saw

Inverters are an essential part of running your circular saw perfectly. This device allows the batteries to move power in the circular saw without hassle. Besides, the power inverter sometimes provides more efficiency to the circular saw. Check the core advantages of having an inverter in your circular saw.

Provides Smooth Moving

Generally, heating and moving devices need more energy for working purposes. As a power tool, a circular saw is also a moving tool. That’s why it needs a lot of power while running. An inverter can help the batteries to provide the current continuously. It transfers the current by following different types of waves.

Current Converting

Circular saw batteries provide DC energy and run in a similar direction all the time. On the other hand, AC current runs in a different direction and handles the system more potentially. An inverter converts the current flow from DC to AC easily. Hence, the inverter can run the device effectively.

High Energy Management

High energy management is a common issue in a circular saw. However, you don’t need to worry if you’ve got the best power inverter for power tools. High watts inverters can manage a lot of energy quickly. It equally contributes energy to the whole device system.

Works As Device Protector

An inverter works as a middleman in your circular saw. It takes the energy from the batteries, changes the current direction, and transfers it to the primary device. In this process, the device cannot be harmed during the current fall and up. 

It is because the inverter supplies only fresh energy to the circular saw. That’s why you can call an inverter your device protector.

Connects Several Batteries

A circular saw contains several batteries. For this reason, it needs a stable connection for moving for a long time. An inverter has the option to connect several batteries at the same time. You can connect all the batteries in single or different ports, also.

What Size does Inverter need To Run A Circular Saw?

As a moving tool, generally, 2000-watt inverters, 3000-watt inverters, and 4000-watt inverters are popular options based on the amp of the circular saw. You may need clarification on the perfect size for your circular saw. To choose the proper inverter size, focus on the four fundamental concepts below.

1. Inverter Type

The inverters are standard of three types. However, sine wave and modified sine wave inverters are the most popular for woodshop workers. Sine wave inverters flow the current in a pure sine wave method. 

On the other hand, modified sine wave inverters switch the flow from positive to negative several times. We appreciate sine wave inverters more than any other inverters for a circular saw.

2. Inverter Capacity

Most medium to large-size inverters can easily manage 10-15 amp circular saws. Generally, it depends on the amp of the circular saw device. 

A 2000-3000 watts inverter is ideal for most circular saws. You must choose a 20% higher inverter size than your tool amp. It helps the device move faster.

3. Number And Type Of The Circular Saw

There are different types of a circular saw. If you want to use a pure sine wave inverter, you must ensure your tool type suits it. Besides, if you plan to connect several circular saws for a single inverter, we suggest choosing 3000-4000 watt inverters. 

In a nutshell, the more you connect your devices, the more watts you need for inverters.

4. Quantity Of The Battery:

The size of the inverter also depends on the quantity of the batteries. If you want to flow a lot of energy, medium to large sizes will be the most effective. Besides, a circular saw always needs a continuous energy supply as a moving tool. 

Sum up all the batteries and compare the result with the inverter wattage.

How to Select The Inverter Size To Run A Circular Saw?

Selecting the correct inverter size for your circular saw may require some calculation. Besides, this calculation can depend on several factors. 

However, you can be done with this calculation by following five steps. Let’s explore the easiest way to choose your accurate inverter size.

Step-1: Check The Label Of The Circular Saw

Every tool contains a label that indicates its voltage and ampere. Check the label first and collect the voltage and ampere correctly. These units are required for the actual calculation of wattage.

Step-2: Measure The Wattage

Now, multiply the voltage and ampere. The result shows how much wattage you will need to run your circular saw. 

For example, 

a 120V and 15 amp circular saw needs a 120V × 15A = 1800W inverter to run the device properly.

Step-3: Understand The Circular Saw Type

The circular saw type must be matched with the inverter type. Otherwise, the whole can fall in. Inverters with abrasiveness and high RPM can’t work with standard-level energy. 

These devices need a high level of power connection. Hence, before connecting the circular saw, understand its type.

Step-4: Decide The Battery Quantity

If your circular is ten amps, you need one or two batteries to run the device. 

On the other hand, a 15 amp circular saw needs two or more batteries. However, you must decide the battery quantity according to the inverter capacity.

Step-5: Pick Your Inverter

Now, the last part always picks the inverter according to the wattage of your device. However, it must pick a 20% higher wattage inverter than the primary device. It runs the tool faster and more smoothly.

Frequently Asked Questions (FAQs)

Will An Inverter Generator Run A Circular Saw?

An inverter generator can run a circular saw more efficiently. It converts the current direction and moves the machine smoothly. Besides, you can protect your device from unwanted damage through an inverter generator.

What Tools Can A 2000-Watt Inverter Run?

A 2000-watt inverter can mostly run moving and heating power tools like a coffee machine or circular saw. Furthermore, if you want to use a 2000-watt inverter in your home, you can efficiently run several devices like a TV, fridge, washing machine, etc.

How Many Amps Does It Take To Run A Circular Saw?

It generally takes 10-15 amps to run a circular saw perfectly. The most popular circular saw contains ten amps. However, to run a potential circular saw, you need a 15 amps device to cut the wood boards.

Final Thoughts

Inverters make the circular saw using experience better! However, to get the best result, you must first learn what size inverter needs to run a circular saw. Proper size maintains the whole system without any hassle. Besides, your device’s health also remains suitable for a long time.
