List of Sukam “square wave” Inverter Models

Su-kam has a wide range of “Square wave” inverters. They call their square wave models as “modified sinwave” inverters or Digital Home UPS.

Modified sinewave inverters are nothing but “Square wave” inverters.

Even Microtek also has named their “Square wave” models as TPZi waveform inverters.

Sukam square wave (modifed sinewave)  inverters are cheaper than Su-kam Sinewave inverters.

Budget consious people who are ready to compromise with their sensitive electronic equipment’s safety can choose SQUARE WAVE INVERTERS (modified sinewave or TPZi wave).

Pure sine wave inverters are always better than Square wave inverters (modified sinewave, TPZi).

Here is the List of Su-kam Modified Sinewave inverters.

    Other than Pico, is there any other portable inverter (in-built battery)? What is the price of Pico?

      Dear Andrew,
      Pico is the only inverter model available with inbuilt battery in sukam.

      • Andrew

        Do any other companies have a portable inverter? I want a portable inverter for a single table fan with 2 -3 hrs backup. Can I use a (computer) UPS? What VA rating should I buy?

          Dear Andrew,
          Portable inverters are suitable for cfl’s and cell phone chargers only.

          Just like computers Ups, it has inbuilt Sealed lead acid 7 AH battery. You can go for APC computer UPS as an alternative for Pico.

          One disadvantage with computer ups is handling, you cannot carry it with you frequently like PICO.

          We strongly recommend, to go for Sukam Micron inverter with 32 AH Car Battery. It will function perform better than your expectation.

          Cost would be

          Sukam Micron inverter – 2500
          32 AH exide champion – 2500

          Total amount – Just 5000/-

          with this configuration, you can run

          one Table Fan (55 watts)
          Two cfl lamps(50 watts)
          One Ceiling fan(75 watts)

          All this appliances will function at the same time.

  • I bought Su-kam micron 250VA running with 32Ah battery,initially it was ok,but after 5 months when 1 ceiling fan 2 cfl is on,its showing over load why? Battery water level is ok & cheked.
