Inverter batteries are the ones which go with saying a Friend in need is a friend indeed, the ones that keep safe and sound and help us in our darkest of times taking care of the rest. Just as our friend expect something in return same goes with our inverter batteries they need to be taken care of and need to well maintained at times of crisis. Taking care of doesn't only mean adding water to the batteries and maintaining them it means a lot more than all of it. Apart from water adding and keeping it safe what it is to maintain it? A lot needs to be taken care of while maintaining the batteries as several other parts which need to be checked while refilling water which is done by our expert professionals of ALL IN 1 Services experts very effectively. Not only it protects the batteries but also increases the battery life.
Invertor, as it sounds is the one that converts DC to AC, which converts a DC potential normally driven from a lead-acid battery into an AC potential which is comparable to the voltage that is observed in our domestic AC Mains outlets.
The inverter is seen in 3 basic stages worldwide and it is observed in the form of,
Oscillator: This stage is the one that helps in the generation of oscillating signals that are usually passed through the IC circuits or transistorizes circuits. These oscillations are basically alternate battery positive and negative (ground) voltage peaks with a particular specified frequency (number of positive peaks per second.) Such oscillations are generally in the form of square waveforms and are termed as square waves, and the inverters which operate with such oscillators are known as square wave inverters. The above square wave can be usually a bit weak and can disappear or can be fed to ahead. In order to avoid such circumstances, the next stage is brought into a picture which can amplify the outcome and be worthy of being used.
Booster or Amplifier (Driver): In here as the caption says the received signal is weak and to be strengthened which is done in this process by amplifying the signal with the help of a booster. Though the boosted response is an AC, it is still at the normal level of battery specified ones and therefore it is not ready to be fed to operate electrical appliances which work at much higher voltage AC potentials. The amplified voltage is then finally applied to the output transformer secondary windings.
Output Power Transformer: As we all know how a transformer does really work; in AC/DC power supplies it is normally used to reduce step-down the applied mains AC to much lower specified AC levels through magnetic induction present at its two windings. In inverters, the transformer is also used for the similar purpose but with opposite orientation, i.e. here the process of reducing or step-down is not done instead the power is step-up increased and fed to its two windings. This voltage is finally used for powering the various household electrical gadgets like lights, fans, mixers, soldering irons etc.


The size of the inverter is always first considered and then measured in watts (W). The amount of wattage (W) needed is later understood which depends on the appliances that are needed to be run on it. Many appliances have the amount of wattage required mentioned on it which is going to be used.

Wattage rating can also be calculated and obtained as    Volts x Amps = Watts

The sum of the wattage of all appliance required/used/going to be worked on should be calculated and should be within the specifications of the inverter; if you are planning an inverter which has 2 outlets then the sum of wattage should be taken and then add another 50% to avoid for any surges in power consumptions. Like taking an example we have a tube light which draws 50 W and a fan which draws 50 W, so all you should go for is at least a 150 W (50W + 50W + 50% of ( 50 W + 50 W) ) inverter. But first, make sure that the power of the inverter used is mentioned as "continuous". They shouldn’t take in the wattage for a short period of time and then stop, reset themselves and again continue the same process damaging the appliances. Such outages can cause troubles and are harmful to the appliances. There are some appliances that at times need a start-up wattage which is much higher than that of the normal running wattage e.g., for example, a washing machine needs at least about 500 W might require 1000 W to start. So the inverter rating should have kept about 1000 W instead that of 500 W, as the washing machine will not kick start.


Power inverters can be of ONE of TWO different types of wave output:

  • Modified Sine Wave
  • True Sine Wave
Modified Sine Wave

Modified sine wave inverter is the most popular ones as well as cheaper. They are efficient enough to run almost all home appliances without any issues. They are also smaller than most of the other inverter.

True Sine Wave

True sine wave inverters are the most expensive but they do deliver the most consistent, highest quality wave output. These can take in high surges at any situations which indicate that they can exceed the rated wattage for the limited time which is again a helpful stats in starting any kind of appliances. Some equipment requires a true sine wave like laptops, battery chargers and so on. AC appliances will run on a true sine wave inverter.
