Inverter Capacity Tester


With this tester, you can assess the capacity of Inverter to handle the load. It gives a warning beep, if the inverter load exceeds above its load handling capacity. Inverters are available in different ‘Size ratings’ from 50 VA up to 50000 VA. VA indicates the ‘Size’ (capacity) of the inverter which represents its maximum load capacity. Commonly available inverters are 500 VA, 800 VA, 1000 VA, 1500 VA etc. An inverter needs Peak or Surge power and Typical or Average (Usual) power to handle the load. Peak power is the maximum power that an inverter can supply usually for short time. If the load increases above the rated capacity of the Inverter, it will over load the inverter that may leads to its permanent damage.

  1. I have a 625 VA inverter with 150 AMP battery. It does not on (run) TV with 97 watt from the inverter (when there is no regular external power supply). The inverter shuts down. But when TV is running with regular (external power supply) electricity and goes off, the inverter and the batter support the TV, it does not get off. What would be the reason? Do I need higher capacity inverter?

    • Hello
      Your Inverter can handle up to 550 watts. The problem is with the battery which is not giving the backup. Check its terminal voltage. It should be above 12 volts. Also check the waterlevel

  2. Hello there! This is my 1st comment here so I just wanted to give a quick shout out and say I truly enjoy reading through your blog posts. Can you recommend any other blogs/websites/forums that cover the same subjects? Thanks a ton!

  3. The inverter battery holds very high current around 45-100 Amperes

    should be

    The inverter battery can deliver more than 100 amperes for short periods of time . . . .

    an inverter battery does not “hold”

  4. hi sir,can we use a 12V power supply for a 12V inverter input instead of a 12V battery? If your answer is yes..then can’t we save some electricity bill? Because it takes only 12V and outputs 220 or 230V! just a little doubt lol

    • Hello Ziddik
      No. The inverter battery delivers very high current around 45-100 Amperes.It is difficult to generate that much huge current through the power supply. So battery is needed for DC-AC conversion.
