# What Size Fuse For 2000 Watt Inverter? Quick Answer

A 20 fuse is the appropriate size for a 2000-watt inverter. Some electricians advise scaling up just a little to give the breaker some breathing room when it comes to controlling power flow. Learn What Size Fuse For 2000 Watt Inverter? is in-depth!

We may use that number to calculate inverter breaker sizes since a 2000-watt inverter can provide 2000 W of pure electricity to appliances. The following equation is used to determine the appropriate breaker size:

“Inverter current output / 120 V = appropriate circuit breaker capacity.”

In this instance, 2000 must be divided by 120. If you’re still unclear, I used 120 because it is the primary voltage offered by the American electrical grid. Please be aware that this number may differ if you live in another country. I suggest you speak with your electrician or look this out online because the voltage going through your circuits can be different.

But I digress. We’ll pick up where we left off: 16.6 is 2000 divided by 120. To obtain the result, multiply 16.6 by 1.25. (expert electrical engineers determined this constant). The final result ought to be 20.75.

Given this, our calculations suggested that the appropriate circuit breaker size for our 2000-watt inverter should be 20.75 amperes. Now, in order to provide some room for error, some electricians advise reducing the circuit breaker size to 25 amp. It is up to you whether you install 20 or 25 ampere-CBs for your inverter, though. However, in most cases, 20 amps should be sufficient to protect your circuits.

## What Size Fuse For 2000 Watt Inverter?

Almost all electrical systems need circuit breakers and fuses, and inverters are no exception. Ensure you have the appropriate circuit breaker installed to protect your equipment, for example, if you plan to install a 2000W inverter.

A 250A circuit breaker and 2/0 AWG size wire are needed for a 2000 12V watt inverter. You cannot use a thinner wire because the inverter could be harmed by the excess current carried by the circuit breaker during a surge.

## Wire Size for 2000 Watt Inverter

Now that you are aware of the recommended 2000-watt inverter fuse size, you might also want to find out what size wire should be used to connect the inverter to the actual breaker.

But first, I’d like to emphasize to you the significance of using the right size wire when connecting circuitry.

The amount of electricity a wire can safely and effectively transport within a circuit depends on its gauge. The amount of energy lost while electricity is transported also depends on the wire’s size. Therefore, 1/0 American Wire Gauge is the appropriate wire size for a 2000 W inverter (AWG).

In addition, I advise you to maintain your cable’s length as short as possible to avoid considerable power loss during the changeover. Electricians advise you to put your inverter close to the items that would use the most electricity. This reduces the electron friction during electricity conversion in the cable wire.

## What Function Does The Fuse Serve In A Power Inverter?

By converting electricity from DC to AC, the power inverter typically creates a continuous flow of energy. It is the smallest appliance used in homes using renewable energy sources.

The inverter can be connected to the solar panel so that the DC is sent from the solar panel to the inverter, or it can be connected using the DC battery. When the DC is run via the inverter, it is transformed into AC. The flow is more effective and energy-efficient thanks to the inverter.

The AC is more dependable and valuable when compared to the DC. The primary grid or the source of electricity is where the Grid Tie Inverter is plugged in. Battery participation is not present.

## What Function Does The Fuse In The Power Inverter Serve?

The fuse technology keeps the system from overheating when the energy flow increases. The flow of energy is always fluctuating. Depending on the supply, it might sometimes go down or up.

The power may rupture the linked line when it reaches the household grid. Your home appliances could sustain power damage if the energy that is substantially loaded makes it there. The fuse manages the circuit’s energy flow. To the battery bank, connect the appropriate fuse. The fuse will prevent any overloads and short circuits.

The fuse’s wire heats up due to the energy surge passing through it. Additionally, if the energy load is too great, the wire will melt, interrupting the system’s current flow. The excessive energy finally disconnects the system because it burns the wire. You must replace the fuse to get the system back to normal after the power is turned off.

The system will break down and start to burn without the fuse. Due to the energy overload, even the system will blow up. Hazardous energy has been stored. It will burn the appliances when it gets to the inverter or the appliances, starting a fire. Therefore, employing the Fuse is crucial to protecting your electronic gadget.

## How To Install A Breaker To A 2000 Watt Inverter Properly?

Now that everything is all up, let’s talk about how to install a circuit breaker correctly for your personal inverter appliance. The following may be tough to understand if you don’t have any prior knowledge of electricity-related topics.

I advise hiring an electrician in this situation if you want their expertise. However, if you have any expertise setting up inverters and are eager to install the actual breaker, then pay close attention to the detailed instructions below.

### Step 1

Disable the main circuit breaker to stop the electricity from flowing. Also, don’t forget to put on gloves in advance to protect yourself from being shocked by any abrupt voltage discharge. Also, unplug any devices that are connected to the inverter.

### Step 2

Carefully remove the bolts and screws holding the circuit breaker plate. After that, hold the breaker that will be inserted into the breaker panel’s open socket.

### Step 3

To identify the wires connected to the panel box, consult the inverter’s instructions. Then, carefully arrange them for your next convenience.

### Step 4

Check the bus bar with a multimeter for any indication of electrical activity. The multimeter shouldn’t be registering any voltage. If there is, make sure the breaker is properly turned off once more.

### Step 5

Obtain the cable needed to link the inverter and breaker. The wire in question must have removed the half-inch of insulation covering the copper conductor. After that, connect the exposed cable to the breaker panel’s neutral bar.

### Step 6

Access the back of your breaker panel in step six. Find the newly installed circuit breaker, then properly connect the wires to the inverter by the manual.

### Step 7

If you followed the instructions exactly, the inverter should turn on successfully and without any issues. Run diagnostic tests to check the inverter’s functionality.

However, if the inverter isn’t functioning as it should, I advise you to review your previous procedures to determine if anything went wrong when you installed the connections.

## Final Verdict

An inverter is one of the chicest electrical items you may have in your house. Its vital capacity to alter the type of energy flowing through your circuit could reduce the amount of electricity used in your home.

However, if you don’t know much about electricity, installing a breaker for your inverter can be challenging. I frequently hear the question, “What Size Fuse For 2000 Watt Inverter?” I believe the information above has adequately answered your question. Gratitude for reading!

### What is the amp capacity of a 2000-watt inverter?

12 Volt DC to 120 Volt AC 2000 Watt 16.7 amps of AC electricity are provided by the Royal Power Modified Sine Inverter.

### What size fuse am I going to need for the inverter?

The general formula we employ in this situation is “Continuous Watts / Battery Voltage times 1.25.” For instance, a normal 1000W 12V inverter uses about 83 continuous amps, and we would add the 25% safety factor, which is 105 Amps. Therefore, we would advise using a 150A fuse.

### For a 2000w inverter, what size circuit breaker do I need?

The calculations led us to conclude that a 20.75-ampere circuit breaker would be a good choice for our 2000-watt inverter. Some electricians now recommend dropping the circuit breaker to 25 amps to allow for some margin of error.

### For a 1200-watt inverter, what size fuse should I use?

Your inverter has a 200A internal fuse, but you must add a second fuse near your battery (by legislation where I reside). I recommend installing a 150 Amp fuse next to your battery’s positive terminal. Your small peaks should be no problem with this.
