A power inverter may sound very strange, but it’s actually very simple to use and relevant to our lives. For example, it allows your car to support the discharge function, which is obviously very useful for using some small power appliances when camping in the wild. From this article, you will have an in-depth understanding of power inverters and choose the right power inverter device.
What is a power inverter?
Simply put, it is a device that converts DC (direct current), which cannot be used directly, into AC (alternating current), which can be used to power some common appliances. In addition to the car battery we mentioned at the beginning of this article, we can also link a power inverter to the solar grid to power more appliances at the same time.
Pure Sine Wave Power InvertersHow does a power inverter work?
A power inverter converts DC power to AC power by turning semiconductors on and off, and adjusts the frequency, voltage, and waveform during the output process to meet the needs of different applications.
How can power inverters help?
If you are not sure what a power inverter does, here are a few practical examples that may help you further understand what it does:
Scenario 1: Vehicle Discharge
In order to facilitate people’s camping and picnicking, there are quite a few SUV vehicles that support the discharge function, such as BYD-Song, Tesla Cybertruck, Ford Ranger PHEV and so on. In addition, we often see a lot of use truck LED display on the road also has such a function.
The Truck’s LED Display Displays Clear AdvertisementsBecause build through the truck LED display to build a stage, you need to use sound, lighting and other equipment, and outdoor usually no socket can be active power supply, at this time we can be through the power inverter will be originally supplied to the automobile screen power conversion part of the supply of sound, lighting and other equipment.
Scene 2: outdoor power supply
There is a kind of power inverter similar to charging treasure, can be charged first or solar charging will be stored in the power, when in the outdoor need for electric kettle, electric fan and other small appliances power supply, the use of power inverters can solve these problems.
LED Poster Display With Stand And Power InverterJYLED has produced a portable version of the LED poster display. On the basis of the LED mirror screen added a power inverter, so that it can be simple and portable, no matter where you can use.
Scene 3: Base station power supply
I do not know whether we have noticed, sometimes the whole area where the power outage, but the signal is not affected, this is because the base station uses a power inverter for power supply.
In some remote or inconveniently located places, where there are many natural disasters, it is easy to cause the power supply of the base station to fail. For this reason, base stations generally have solar batteries built in.
When the power supply is detected to be insufficient, the power inverter will be used as a backup power source to supply power to the base station, so as to ensure that the base station can be used stably.
How to choose a power inverter?
In the market, there are many different models of power inverters, we can choose according to the following parameters:
Wattage
First of all, we need to understand what appliances should be used on top. When applied to smaller power devices, such as cigarette lighters, cell phone charging, usually choose 20W, 40W and other power output power inverter; when applied to the electric kettle, rice cooker and other power appliances, usually choose 1000W, 3000W and 5000W. Of course, there are like the sunshine inverter such as more enough to output more high-power devices, but this general is mainly used in industry, so they are not very common.
Size
Power inverters of different wattage naturally come in different sizes. A 20W or 40W inverter can be used in a car, while an inverter with a wattage of 3000W or more will require some space to be placed.
Waveform type
Power inverters are categorized into pure sine wave and modified sine wave. Pure sine wave power inverters appliances have no other disadvantages except higher price, while modified sine wave power inverters are cheaper, so they are only suitable for less demanding appliances, such as lamps, small appliances and so on.
How to use a power inverter?
Different power inverters are used in slightly different ways, for most of the power inverters, we just need to plug them in according to the corresponding interface to output power. Only some larger power inverters may need to be connected directly to the battery.
