Understanding Car Power Inverters

Before understanding what a car power inverter is, it is important to understand the difference between AC and DC power. In very simple terms, AC is the power you get from outlets in your home and DC is the power you get from batteries.

Since car batteries provide DC voltage and most consumer electronics run on AC power, if you want to use AC devices on the road, you need a device called a car power inverter. With a car power inverter installed, you can take almost any electronic device in your home or office, plug it into your car, and use it as normal with a few caveats.

Some of the most important restrictions to keep in mind when using an inverter in your car include factors such as car battery capacity, alternator rating, and power output. of the inverter.

The truth is that your car’s electrical system can only produce a limited amount of power and the battery can only provide a limited amount of power before it dies, so all of these factors can play a part. in determining which devices can be connected. converted into a car inverter and used on the road.

How Inverters Work

Inverters operate by using unidirectional DC power to emulate alternating current (AC) power. Electronic inverters are essentially oscillators that rapidly change the polarity of DC power and create an effective square wave.

Since most consumer electronics require something closer to a true sine wave, most inverters contain additional components that create a modified or pure sine wave.

Who needs a car inverter?

Anyone who spends a lot of time on the road can benefit from some type of inverter. These devices are especially useful for long trips, camping, business travelers, truck drivers and other similar applications.

Some devices, such as cell phones and laptops, can be used with 12V accessories that plug directly into the cigarette lighter or accessory outlets. However, any electronic device that requires AC input requires an inverter. Some devices you can run a car inverter with include:

  • televisions
  • DVD and Blu-ray players
  • gaming systems
  • catalytic radiators
  • kitchen equipment
  • power tools

What are the different types of car inverters?

There are a number of different types of inverters, but the two main types you will find in automotive applications are:

  • Modified sine wave
    • These inverters are the more affordable of the two. They produce a “modified sine wave” that is great for most consumer electronics, so they work well in many different applications.
  • pure sine wave
    • These tend to be more expensive, but they produce a sine wave that’s much closer to the AC current available at your home’s electrical outlets. Some devices, such as uninterruptible power supplies, may not work properly without a pure, constant sine wave, but most consumer electronics will work just fine without one. If you are concerned, you should check with your device manufacturer before investing in an expensive pure sine wave inverter.

How are inverters connected?

For this to work, an inverter must be connected to the car battery somehow. Some of the most common configurations are:

  • fuse panel
  • directly to the battery
  • Lighter
  • 12v accessory socket

The easiest way to hook up an inverter is to plug it into a cigarette lighter or other 12V accessory outlet, but there are some limitations to this type of setup.

There is an inherent limitation to the types of devices that can be connected to the inverter as there may be a cigarette lighter or other components connected to the accessory circuit. Inverters connected this way are usually limited to a 5 or 10 amp draw.

In heavier applications, the inverter should be connected to the fuse panel or directly to the battery. Some fuse panels have empty slots in which an inverter can be plugged in, which will provide a dedicated circuit for the device. In other cases, the inverter can be connected directly to the battery with a fuse. Either way, it is essential to use some form of insurance to avoid a potentially dangerous situation.

Additional Considerations

Since most cars and trucks are not designed for inverters, it is important to avoid overloading the system. An essential factor to consider is the battery capacity. If an inverter is used while the vehicle is not in motion, it will tend to drain the battery quickly.

Some trucks have extra space under the hood for an extra battery which can help lessen the impact of using an inverter when the vehicle is not running, but that’s not always an option.

While using an inverter while the vehicle is in motion ensures that the alternator battery remains charged, it is also essential to avoid overstressing the alternator. Since alternators are typically designed to provide enough power to run all of a vehicle’s electronics and keep the battery charged, they may not have enough extra capacity to run a powerful inverter.

The best way to avoid a problem in this area is to check the power rating of your alternator and then purchase a suitable inverter. If that’s not enough, there may be an OEM option for a higher output alternator that you can replace, and sometimes aftermarket units are available that provide more power.

Understanding Car Power Inverters

Before you can understand what a car power inverter is, it’s important to understand the difference between AC and DC power. In very basic terms, AC power is what you get out of the outlets at your house, and DC power is what you get out of batteries.

Since car batteries provide DC voltage, and most consumer electronics work on AC, you need a device known as a car power inverter if you want to use AC devices on the road. With a car power inverter installed, you can take just about any electronic device from your home or office, plug it into your car, and use it as normal, with a few caveats.

Lifewire / Adrian Mangel
Some of the most vital constraints to keep in mind whenever you use an inverter in your car include factors like the capacity of the car battery, rated output of the alternator, and output wattage of the inverter.

The fact is that the electrical system in your car can only put out a finite amount of power, and the battery can only provide so much before it goes dead, so all of these factors can all play a part in determining which devices can be plugged into a car power inverter and used on the road.

How Do Inverters Work?

Inverters function by using a unidirectional DC power source to mimic an alternating current (AC) power source. Electronic inverters are essentially oscillators that rapidly switch the polarity of the DC power source, which effectively creates a square wave.

Since most consumer electronics require something closer to a true sine wave, most inverters include additional components that create either a modified or pure sine wave.

Who Needs a Car Inverter?

Anyone who spends a lot of time on the road can benefit from some type of inverter. These devices are especially useful on long road trips, for camping, people who travel for business, over-the-road truck drivers, and other similar applications.

Some devices, like cellular phones and laptops, can be used with 12v attachments that plug directly into a cigarette lighter or accessory jacks. However, any electronic device that requires an AC input calls for an inverter. Some devices that you can run off a car inverter include:

Televisions
DVD and Bluray players
Game systems
Catalytic heaters
Cooking equipment
Power tools
What Are the Different Types of Car Inverters?

There are a number of different types of inverters, but the two main types that you’ll find in automotive applications are:

Modified sine wave
These inverters are the more affordable of the two. They produce a “modified sine wave” that’s perfectly fine for most consumer electronics, so they work well in a lot of different applications.

Pure sine wave
These tend to be more expensive, but they produce a sine wave that is much closer to the AC power available from the power outlets in your home. Some devices, like uninterruptible power supplies, may fail to work properly without a steady, pure sine wave, but most consumer electronics will work just fine without one. If you’re concerned, you should check with the manufacturer of your device before investing in an expensive pure sine wave inverter.

How Are Inverters Hooked Up?

In order to work, an inverter has to be hooked up to the car battery in some way. Some of the most common configurations include:

Fuse panel
Direct to battery
Cigarette lighter
12v accessory socket

The easiest way to hook an inverter up is to simply plug it into the cigarette lighter or another 12v accessory socket, but there are some limitations to that type of setup.

Since there may be other components hooked up to the cigarette lighter or accessory circuit, there is an inherent limitation on what type of devices can be hooked up to the inverter. Inverters that are connected like that are generally limited to a 5 or 10 amp draw.

In heavier duty applications, the inverter needs to be connected to the fuse panel or directly to the battery. Some fuse panels have empty slots that an inverter can be wired into, which will provide a dedicated circuit to the device. In other cases, the inverter can be connected directly to the battery with an in-line fuse. In either case, it is vital to use some type of fuse to avoid a potentially hazardous situation.

Additional Considerations

Since most cars and trucks aren’t really designed with inverters in mind, it’s important to avoid overtaxing the system. One vital factor to consider is the capacity of the battery. If an inverter is used when the vehicle isn’t running, it will tend to rapidly deplete the battery.

Some trucks have extra space under the hood for an additional battery, which can help reduce the impact of using an inverter when the vehicle isn’t running, but that isn’t always an option.

While using an inverter when the vehicle is running will allow the alternator to keep the battery topped up, it’s also vital to avoid overstressing the alternator. Since alternators are typically designed to provide enough power to run all of the electronics in a vehicle and keep the battery charged, they may not have enough additional capacity to run a powerful inverter.

The best way to avoid a problem in this area is to check into the rated output of your alternator and then buy an appropriate inverter. If that isn’t enough, there may be an OEM option for a higher output alternator that you can swap in, and aftermarket units that provide even more power are sometimes also available.
