Advantages of Sine Wave Inverter – 8 Points to consider


I hope you know there are two major types of inverter.

1. Square wave or modified sine wave inverter

2. Pure Sine wave inverter.

In these two major types, Sine wave inverters are superior in quality and performance. It doesn’t mean square wave inverters are inferior, square wave or modified sine wave inverters have their own specialties. But the fact, all of us should accept is ‘sine wave inverters are better than square wave or modified sine wave inverters’.

In which way Pure Sine wave inverters outperform square wave?

1. Simple, the square wave inverters are built old technology whereas pure sine wave inverters built with State Of The Art Technology.

2. In Sine wave inverters, the fan or tube lights won’t make any humming noise.

3. Sine wave inverters gives the same current which you get from power grid whereas square wave inverters gives the current with different wave form that is not safe for motors, induction applications, sensitive electronic devices.

4. Output voltage from sine wave inverters is with in the 230 volts limit whereas square wave inverters output voltage may touch 290 volts.

5. Some branded stabilizers and compact computer UPS won’t accept the wave form of square wave inverters, in such case the TV stabilizers or computer UPS need to be bypassed or removed to continue using the TV or Computers with square wave inverter. You don’t need to face such a problem with pure sine wave inverters; they operate seamlessly with any type of stabilizers and compact computer UPS.

6. You don’t need to purchase a separate UPS for your desktop computer as Sine wave inverters take care of your pc like a dream.

7. Sine wave inverters gives extended power back up compared to modified sine wave of square wave inverters. It saves your current bill.

8. You can operate Mixie or Grinder safely with sine wave inverters. (850 VA inverters and above)

    dear sir your this article has made clear the difference. i have a normal inverter but i use my laptop daily for 4 to 5 hours on this so is it harmful?

    Dear Aman,
    For time being you can use square wave inverter to charge your laptop battery. But try to change your inverter to pure sine wave very soon.

    I am sure, Square wave inverters are harmful to laptop batteries and laptop chargers.

    Dear sir i have decided to buy luminous Inverter 875va sine wave+ tall tubler battery 150ah with 36+12month wich cost is 17k by dealer .is the choice is right. i am from rural area. power supply max10hour with low voltage. pls suggest.thanks in advance

      Dear Awadhesh,
      If you don’t have any idea of connecting your LCD TV to inverter, we strongly recommend to go for Luminous “Shakthi Charge 900VA inverter” with 150 ah battery.
      Though ‘Shakthi charge’ is square wave inverter, it is the only model from luminous with high power charging facility of 16.5 amps current. Normal sine wave Luminous inverter is available with only 10 amps current charging facility.
      Since you are suffering with 10 hours power cut, normal inverters could not recharge your 150 ah battery so quickly as ‘Luminous Shakthi Charge’

      Hope this post will give you clear idea about Price of Shakthi Charge inverter

    my microtek sinewave 850sebz is not working properly
    battery charge is empty

      Dear Jyothiraj,
      Both Battery and inverter should be checked by technician. Call your battery dealer first.
