Power rating of inverter battery for the houses.

Power shortage in Chennai and other cities is common, but it is essential that there is an uninterrupted power supply to use appliances at home. As a solution to this problem, an inverter in Chennai is popular. Inverters are electrical devices that can convert a voltage from DC to AC. It contains a battery which enables the supply of electricity to be uninterrupted. The inverter transforms the DC voltage that comes from the battery to AC through its design. The battery has a charging mechanism that gets stored and utilized when there is no electricity supply. A Microtek inverter system and other such inverters ensure that when there is electric supply, the power charges the battery and also supplies loads to your house.

Is Microtek Inverter right for my home

If you are in the process of looking for a new inverter or upgrade from an old one, then it is essential that you know which inverter is best for your home. Every house has different power needs and hence what works for your neighbor may not work for you and vice-versa. So instead of installing the Microtek inverter that your friend or neighbor in Chennai installed, do your homework on the various types of inverters, including Microtek inverter and if possible Luminous inverter and see if it fulfills your power requirement.

The most critical factor that you should determine before investing on an inverter is the Power requirement. That means when there is a power cut in your Chennai home, what are the electrical appliances like the fan, TV, lights, etc. that you want to run during the time there is no electricity supply. That is apart from the power consumed by various electrical appliances. For example: If you’re going to run 3 Fans, 1 TV, and Tube lights at the time of power cut. The electricity consumed by these are, as below calculation

1 Fan -70 watts, so 3 Fans = 3*70=210 Watts

1 Tube Light – 60 Watts, so 3*60 = 180 Watts

1 Tv- 120 Watts

So the power requirement is 210+180+120 = 510 watts

How to Calculate the VA rating of A Microtek inverter :

VA is the Volt-Ampere rating. It is the current and the voltage that the inverter provides to the appliances. If the efficiency of the inverter is 100% than the power requirement of your house and that offered by the system is same. But, ideally that does not happen, and most inverters provide about 60 to 80% efficiency. That efficiency is known as the power factor which is the ratio of power required by power supplied by the inverter. So the power factor is 0.6 to 0.8. If an average of the power factor is considered, it will be 0.7. The Power of inverter you will need as per the above example is 510/0.7 = 729 VA

So 800VA inverters available in the market will be the best for your home.

Battery Capacity  your Microtek inverter needs:

The most crucial component in an inverter system is the battery. The performance of this inverter is dependant on the quality and the back up it provides. The battery capacity determines the number of hours the appliances run.

There are batteries capacities of

  • 100Ah
  • 150Ah
  • 180Ah
  • 200Ah

To find the battery capacity that the inverter needs, consider that your Chennai home power cut lasts an average of 3 hours at a time.

Battery capacity = Your power needs(Watts) * No of Hours for Backup (hrs)/ Voltage(Volts)

BC= (510*3)/ 12 = 127.5

So, you will need a battery with capacity of 130 Ah.

How to maintain your battery

Apart from knowing the right inverter and the inverter battery dealer to buy, there are a few things you should always bear in mind post-installation.

  • You should always use a well-ventilated area to keep your inverter. The battery of the inverter gets hot when in use or while it is getting charged. So it is essential that there is enough air circulation so that the heat escapes, that will ensure the battery works optimally and also the frequency of adding distilled water is even less.  
  • Ensure that the battery is in use regularly. If it so happens, that there are no power cuts in your neighborhood in Chennai, you should discharge the battery completely at least once a month and recharge it back.

As the world increasingly comes to rely on electrical and electronics systems for its functions, it is also becoming increasingly dependent on batteries. As electrical and electronics systems become more efficient, batteries provide the key for operation and, even with stationary systems, batteries are becoming increasingly important to provide power supply backup or keep essential functions operational when the main power is not available.
