So many times people who own Inverters, ups or Generators don’t understand how and what this term is, in this blog post my interest is that you have a fundamental understanding of what power factor is, and this will guide you to know what exactly or how to size an Inverter for your appliance.

From Stabilizer to Inverters, all power enhancing systems have a power factor which simply is the percentage or the ratio of input to output of (in our context) the Inverter. How does this work?

Let’s get back to primary school maths, (lol, the math you have always avoided as met with you, lol) , so like we where saying,

100percent simply means 100/100 which equals 1, a perfect number, or 1:1 ratio, for example I filled my cup with water and drank all the water, meaning the amount I poured into the cup is still the number I consumed, and nothing was lost.

becoming a bit technical, when you get an Inverter, be particular about what the Inverter manufacturer tells you in its specification, some Inverters come with a power factor of 0.6pf(power factor) meaning, this Inverter even though it’s a 1200va or 1.2kva it’s expected power is reduced as we multiply 1200va by 0.6pf to get 720watts the capacity of the Inverter, while some are 0.8pf and a few 1pf.

A little basic physics will help

Power (which is current x voltage) = power

Power =power

IxV( current x voltage) =power

So when saying 1200VA(they replaced with “I”, let’s not go into details of why in this post)

So it’s expected the 1200VA = 1200watts, but not so at all times and can only be true when the power factor of the Inverter is “1”.

So to convert kva to watts, please first multiply the va with pf to know the rates watt capacity of the system.

If you have questions, please it’s our pleasure to guide you as you in your Inverter story.
