What Is A Pure Sine Wave Inverter?
It is a device that changes direct current to alternating current that is DC to AC power. Meaning it changes electric charge without storing or producing electricity. It has a gradual peak, mostly used to transform electricity from batteries and fuel cells to alternating current electricity, AC.
Besides, most appliances nowadays are designed to work with them, as they require true sine wave for optimal functionality. In addition, inverters are an essential part of a home solar power system.
How Does a Pure Sine Wave Inverter Works?
As for how a pure sine inverter works, here is a three-stage process of how it converts DC to AC power.
- Oscillator Stage
Here it generates oscillating pulses via a transistorized or an IC circuit. These oscillations then produce an alternate battery with positive and negative voltage peaks, with a specified frequency number or the number of positive peaks per second.
However, due to their weakness, they cannot be used to power up any transformers of high current output. Therefore, these pulses are sent to the inverter’s amplifier.
- Booster or Amplifier Stage
In this stage, the oscillation pulses get a boost to a higher current level. Although the electricity is in AC form, the voltage is still low at battery level, and cannot operate an electrical appliance.
For the voltage to rise to a level suitable for electrical appliances, it is applied to an output transformer secondary winding.
- Output Transformer Stage
Here the low-level AC power from the booster stage is applied to the secondary winding of the sine wave inverter’s transformer. This results in a stepped-up voltage, which the inverter generates to allow you to use a variety of AC appliances.
Pure Sine Wave vs. Modified Sine Wave Inverters: Which One to Choose
When it comes to choosing between the two inverters, you are better off with the facts, advantages, and disadvantages of both. This guarantees a better choice and option:
- Pure Sine Wave Inverter
These inverters are usually suited for operation of sensitive electronic appliances, which require high-quality waveform with very little harmonic distortion.
Besides, they have a higher surge power meaning they can easily exceed their watt rate for some time and allow motors to start easily. Moreover, any electronic device can operate with it.
- Modified Sine Wave Inverter
On the other hand, modified sine wave inverters are built to satisfy the required efficiency of the photovoltaic system. It uses basic technology to produce power for running simple electronics.
Moreover, it can operate a variety of loads and is ideal for household items like a television, computers, printers, microwave oven, light bulb and a satellite receiver.
You should note that this inverter cannot work with most modern appliances, thus very limiting.
Therefore, you should always settle for an inverter with sine wave technology, as it can power up small and big electronics ensuring quality output. Besides, it guarantees a smooth sine wave current similar to a home electric current you get when you plug a system into an electrical grid.
In addition, its output is usually stable and effective for any load. It can prevent computer crashes and weird glitches in an appliance.
The only downside is that it is costly when compared to a modified sine wave inverter, which is always less expensive but limited when it comes to powering up modern devices.
Things to Consider While Buying
When shopping for an inverter, you should know some necessities for a quality one. Otherwise, you might end up with a shoddy inverter, which will not meet your needs at all.
Here are some top considerations for a quality functional pure sine wave inverter.
- Watt power– This depends on what you are buying it for, as different appliances often have different watt power. Nevertheless, you can always buy one inverter with a slightly higher watt power than you actually need, saving you a lot of trouble
- Continuous load and peak load– Peak load is usually the maximum load that the inverter can handle. This is usually for a short duration of time, a few seconds. A continuous load is how much the inverter with sine wave can run normally. Therefore, check the specifications for this before making the purchase
- Current waveform– These often produce a sinusoidal current like the one that a utility line delivers. It is smooth and pure and peaks gradually. Besides, it is the best current for all AC appliances, especially the modern ones
- Maintenance options- A sine wave inverter should always receive regular maintenance. You can hire an expert to do the maintenance. Cost should never be an issue, as your priority is to have the inverter up and running. You can also use the Original Equipment Manufacturers, OEMs, plan but it is rather expensive when compared to hiring a third party professional
- Cost- This usually depends on the model as well as features. More features equal higher costs. Nevertheless, you should always buy a quality product that will meet your needs. Otherwise, you will end up rendering it ineffective and worthless
You can also consider some of these important features before making a purchase
- USB port– Most inverters with small watts have a USB port that allows for the power inverter to charge through it
- Air compressor– Some compressors usually have inbuilt air compressors. It can help with pumping stuff like tires
- Display– You can also check for LCD display as some have and others do not have. The most expensive sine wave inverters have this
- Power jump starter– This feature is essential for those who want to use the sine wave tech inverter to power up a car or a car battery. It usually comes in handy when your car stops
- Overload protection– The best and most expensive inverter with sine wave capabilities has this feature for adaptability, in case you plug a high powered device on it
- Solar charging feature– This is for the clean energy folks that want to charge the sine wave machinery using solar energy. It is a very useful feature and a convenient one too, as the sun always shines in some parts of the world
