The 1000-watt power inverter is one of the most popular inverters among boaters and people with recreational vehicles. But you might be asking, what will a 1000-watt power inverter run? The short answer is a lot of devices. Your inverter can also charge power tools.
While it runs small devices effectively, your inverter can run larger devices like a toaster, coffee machine, and air conditioner. You only need to check the power that these appliances will consume. You do not want to overload your inverter because it will develop malfunctions. Also, it would not serve you efficiently if you had your power inverter improperly wired during installation.
So What Will a 1000-Watt Power Inverter Run?
First, let’s start by defining an inverter.
What is an Inverter?
An inverter is a device that converts direct current (DC) electricity to alternating current (AC). Inverters can be used to help you start your car, charge batteries, power your home, or run some other electrical equipment. A typical inverter has AC outlets, USB ports, and an alarm.
The Difference Between DC and AC Power
Direct current (DC) power involves a linear electrical current. I.e., power moves in a constant direction. Most electronic devices rely on energy from DC power sources because of the consistency in voltage. Some devices, however, use alternating current delivered directly from the power grid.
Alternating Current (AC) power involves a flow of charge that exhibits a non-linear direction. The current flow keeps changing between positive and negative.
Types of Inverters
Inverters can be categorized into two:
- Modified sine wave inverters
- Pure sine wave inverters
Modified Sine Inverters
These are more affordable power inverters that have a non-linear transfer function. This means their output comes out more erratically – the flow has more peaks and ebbs.
Pure Sine Inverters
Pure sine inverters are exceptionally efficient, high-performance inverters that provide high-quality power. Pure sine inverters are reliable as they offer excellent thermal stability. These inverters can be quite expensive.
Pure sine inverters are the perfect choice since they will ensure the optimal performance of your devices. Pure sine inverter’s stable power flow also enables the appliances to last a long time.
So what will a 1000-watt power inverter run?
The wattage consumed by each of your appliances determines what your 1000W power inverter will run. Your electric device has the power details written. When using multiple devices, you’ll check and sum up the wattage requirements to get the total power usage.
A 1000W power inverter will run most of your household devices, including TVs, VCRs, DVD players, space heaters, and other low-load devices. Do not overload your inverter. It needs a 10-20% safety margin when operating at full load. The safety net is important because:
- The inversion process may consume some energy, meaning that the inverter may not operate at 100% efficiency. The inverter converts DC to AC power.
- Many people run multiple appliances from the same inverter, and the safety net will prevent overloading.
The formula below will help you answer the question, what will a 1000W power inverter run?
Required Watts= Amps x Volts
Assume your plasma TV is marked 4 amps (using a 100 Volt AC). If we apply the formula, 4×100= 400 watts. Your inverter will run this TV. It is within the required wattage even if you include the 20% safety net.
This means you can also plug in some other appliances, too. For instance, you can plug in your 3.1 amp-rated game console. 3.1×100= 310 watts. You may also add your laptop, cell phone, and other gaming devices.
If you have a coffee maker rated 12.5 amps; 12.5×100= 1250 watts. This is beyond the capacity of your inverter. You may have to work with a 1500 or 2000-watt inverter.
If you plan to use over 2000 watts of power, getting a generator over an inverter may be a safe bet.
Can a 1000-Watt Inverter Run a Refrigerator?
The size of the refrigerator matters (it determines the running wattage). The fridge motor may need up to three times the running wattage before starting. However, the fridge will only need this amount of surge power for a split second. This can help determine the peak wattage for your inverter.
Assume the running watts for your fridge is 600 watts. This means your inverter needs to support 600 watts for extended periods to run a refrigerator. It should also have the power to support a surge current of 1800 watts for a split second when the fridge powers up.
The best advice is to use an oversized inverter (for instance, a 1500-watt inverter). The idea is to support any overloads that may happen for short periods. Your 1000-watt inverter may not support a 1200-watt continuous load. In this case, a 1500-watt inverter will serve you better.
Use oversized inverters to take care of 15-20% of overloads that usually happen.
Can it Run a Vacuum?
A 1000-watt power inverter can run a vacuum, but you have to check the wattage. The vacuum’s suction power determines its power, and a typical vacuum may need a lot of power to run. Check your inverter’s output voltage.
The start-up surge for motor-driven appliances is usually 3-10 times more than the continuous load. A 700-watt device may need over 1400 watts to start. Your 1000W inverter may handle the start-up surge but won’t handle the full load.
Can it Run a Hair Dryer?
One of the most power-hungry appliances is a hair dryer. Most hair dryers have a rating of 800 to 1800 watts. Running a hair dryer for a longer period needs a powerful inverter. A 1000-watt power inverter can start a hair dryer and run it on its lowest setting. This ensures limited power consumption.
Can a 1000-Watt Inverter Run a Coffee Maker?
It depends on the size of your coffee makers. If you have a relatively small coffee brewer (5-8 cups), the rating could be between 550 watts and 900 watts. Your 1000-watt power inverter will run this coffee pot.
Espresso coffee machines may need up to 1500 watts of power to run. This may require a 2000-watt inverter. Considering that the inverter will use some power, giving a 20% safety room is good.
How to Size Your Battery Bank
Your inverter cannot operate independently. It needs the right size battery bank for optimal performance. Failing to provide the right size can lead to dysfunctionality, or the inverter may even shut off.
Batteries store energy in DC form. For the power to be usable, the inverter draws it from the battery and converts it to AC. The process of drawing power from the battery results in a significant drop in the battery voltage. It recovers as the battery’s liquid electrolyte mixes and comes in contact with the battery cells.
The batteries you use must be able to handle the initial draw at start-up. If the batteries fail, the inverter will not function as required. It can cut off power or completely shut down. Other variables that can cause a malfunction include poor battery health, the battery being too small, or cold temperatures.
If you use a 1000-watt power inverter to run your laptop, the best choice is to get a high-capacity battery. Used at peak load, a 100-watt battery will run a 1000-watt inverter for over an hour when at full capacity.
Get Yourself the Right Inverter
The key to selecting the right inverter is understanding what you will be powering. When camping or on a road trip a 1000-watt inverter will help run many of your small appliances, like your hair dryer, and charge your devices, including your phone and laptop.
How Long Does 1000 Watts Last?
To determine how long your inverter will last, check the power-consuming devices you want it to run. Too much load will reduce run time. It would not serve you efficiently if you had it improperly wired during installation.
What Size Inverter Should I Buy?
The size of the inverter you should buy depends on the power consumption of your appliances. Check the specification plate for information on power consumption. It is best to buy an inverter that’s larger than what you think you need (leave a 10-20% safety net).
What’s the Difference between a 1000W and a 2000W Inverter?
The difference between the 1000W and 2000W inverters is that the 2000W inverter is more powerful. It offers double the capacity of the 1000W inverter.
What’s the Difference between Modified and Pure Sine?
The difference between a pure and modified sine inverter lies in the appliances they can work with. Pure sine inverter can run all AC appliances. A modified sine inverter may not run devices with moving parts since its output constantly changes from positive to negative.
