An example of such a device is the BESTEK 400W/500W Car Power Inverter DC 12V to AC 110V Car Inverter.
Types of Pure Sine Wave Inverters
There are different types of inverters. There are square wave, sine wave and modified sine wave inverters. This means that the pure sine wave inverter is actually a type of an inverter. There are no sub categories present. This means that you can only distinguish between the different types of pure sine wave inverters based on their power output, physical construction, size, number of USB ports available and advanced features.
Why You Need a Pure Sine Wave Inverter
Power on the Go
Pure sine wave inverters allow for you to provide power to your devices by using power from a battery. Such devices include tablets, laptops, mini-fridges and more.
Do you have power sensitive equipment? If the answer is yes, then pure sine wave inverters are for you. These devices are capable of providing emergency power as they convert DC power stored in your batteries to AC power. There are even some pure sine wave inverters that are able to automatically change over from AC power to battery power in a period of just 10 milliseconds.
Pure sine wave inverters are usually portable. This means that you can use them in your RV. When you no longer want to use your RV, you can carry it with you and use it in your boat or even in your home.
Factors to Consider When Buying a Pure Sine Wave Inverter
Different pure sine wave inverters are able to provide different amounts of power. You need to first sit down and calculate how much power you need. Make sure to leave room for adding additional devices e.g. if you need 400W, then go for a 500W device.
Surge Power Capabilities
Different electrical devices behave differently. Devices with motors – pumps, blowers, saws, etc. usually have a high starting current. This means that you may consume up to 3 times the power rating of the device during the first few seconds of operating the device. You need an inverter that will be able to withstand such surges.
It is usually a good idea to have a pure sine wave inverter that is portable. This will allow you to use it in another application. An example is a sine wave inverter that you may have in your RV. You may want to use it in your boat when you take a break from travelling.
Safety is of paramount importance. It makes the difference between having a pleasurable experience and going to the emergency room. Try to look for pure sine wave inverters from reputable manufacturers. Also ensure that they have safety protection against overload, over voltage, over current, under voltage, reverse polarity as well as overheating.
Pure sine wave inverters are expensive devices. You certainly do not want to buy a pure sine wave inverter and have it malfunction after a week of use. The warranty gives a good indication of the manufacturer’s confidence in his or her product. As a general rule of the thumb, the pure sine wave inverters with longer warranties are made from better materials and last much longer than similar products that have shorter warranties.
What is a Pure Sine Wave Inverter?
A pure sine wave inverter is an electrical device that converts Direct Current to Alternating current and produces a very similar output to the utility supply.
How Does a Pure Sine Wave Inverter Work?
The operation of these devices can be divided into the following stages.
Power is input to the device. This power comes from a DC source, and in most cases car or solar batteries are used.
The inverter generates oscillating pulses through an IC circuit in this stage. Alternate positive and negative voltage peaks generate by these oscillations with a particular frequency. These need to be amplified.
The alternate voltage generated by the pure sine wave inverter oscillator is amplified to high current levels in this stage. The voltage will still be the same i.e. it will still be 12 V (assuming that 12V batteries are used).
As you know, electrical devices in this country operate at 120V. This means that the 12V signal needs to be stepped up to 120V. A transformer steps up the signal from 12V to 120V. This power can then be used via the power sockets present on the outer casing of the device.
Pure Sine Wave Inverter FAQs
Can it Charge Batteries?
It depends with the model. Some pure sine wave models offer this feature and some do not.
How do I Clean It?
Using a dry cloth when the device is off must do the trick. Make sure that you do not use water and do not open the device.
Can I Cook With It?
No. If you want a device that allows you to cook on the go, consider purchasing a gas stove.
Can It Run a 145W Gaming Laptop?
That rating is lower than all the devices that have been reviewed in this article, so if you buy any products from this article then the answer is a big yes.
Can I Use It to Run My Electric Saw?
In most cases, no. Try using a diesel generator instead.
