In today's time where power supply is erratic and electricity costs doubled over the past year in some Australian states (Energy Australia), power back-ups became a significant part of Aussie households. Sine wave inverters are great for emergency home power back-up.
Sine wave inverters convert DC (Direct Current) from a battery to AC (Alternating Current) that is used to operate all kinds of devices. They are categorized into three types: pure sine wave, modified sine wave, and square wave, with the former two being used to support household appliances. Sine wave inverters are also an essential component in solar installation. The sunlight collected by the solar panel will be converted into DC output which will be sent through the solar charge controllers then to the inverters which will transform it to AC energy while also changing the voltage.
These power inverters are also noteworthy for mobile life, camping or constant road travels while still enjoying the modern conveniences that require electricity. So when you find yourself contemplating what to get for your home or your "mobile home", here are the major differences between pure sine wave and modified sine wave inverters:
| Specs | Pure Sine Wave | Modified Sine Wave |
|---|---|---|
| Application | AC power produced closely matches an actual sine wave. Great for sensitive equipment like newer TVs, CFL light bulbs, and appliances with AC motors (microwaves and refrigerators). | The polarity abruptly switches from positive to negative which has a negative impact on delicate, sensitive equipment. Used in devices that don't use a non-variable speed motor. |
| Grid-tie solar system | Off-grid solar system | |
| Efficiency | Produces cleaner, smoother, quieter, and more reliable electricity. | Uses up to 30% more power and cannot run its full capacity |
| Cost | Costly as they are expensive to produce | Cheaper as they are simpler to produce with fewer components |
| Interference | Output voltage waveform has very low harmonic distortion | Produces a hum with devices attached to it. |
| Size | Larger | Smaller |
In order to protect your home appliances, pure sine wave inverters are definitely recommendable as they will extend the lifespan of your devices. Due to the suitable amount of wave output, your appliances and equipment will run cooler and more effectively thus reducing the odds of malfunctions. Pure sine wave inverters are indeed fancier than modified sine wave inverters but they provide more benefits living up to its costliness.
Modified sine wave inverters are also highly efficient when used with suitable devices. And Elinz just has the perfect deal if you are looking for this type of power inverter. Grab it now!
