Inverter And Battery Connection, Installation At Home

Today we are going to know How to Install Inverter and Battery at Home, Inverter connection diagram. Load shedding in our country is very much so we need to install Inverter in our home. In this article, I have tried to explain the full details about the Installation of Inverter at our Home.

Why we need Inverter

There is only one thing that is Battery is available by which we can store electrical energy for use during load shedding. But we know that battery is a DC source. In our home, the all electrical equipment made for 230 V AC supply. So we need 230 V AC supply to run our electrical equipment during load shedding. The inverter in our house is a device which takes 12 V DC supply and gives 230 V AC Supply. So Inverter is a circuit or you can call a device which converts DC to AC.

How to Select Rating of Inverter for Home

If you want to install an Inverter in your home then first you must select an Inverter of perfect rating which can drive the loads which you want. So the selection of rating of Inverter is very important.
For select the rating of the Inverter you need to calculate the load which you are want to run during load shedding.
For Example, you want to connect
                           2  Fan of 70 Watt = 140 W
                           2  Tube Light of 60 W= 120 W
                           2  LED light of 15 W = 30 W
                           1  Television of 120 W = 120 W
                           3 CFL of 25 W = 75 W
 So, the total load is = 485 W

You need to select the rating more than your total load because when we just ON any electrical device it draws a much current at starting time. The inverter has the rating in KVA so you need to purchase 800 KVA Inverter if your load is 500 W to 600 W.

Selecting Rating of Battery for Inverter

You must select the rating according to your required time of use that means if want to use the inverter 3 hours and your load is 485 W then the rating of the battery must be,

(485*3)/12=122 Ah

As 122 Ah battery is not available in the market you can purchase 150 Ah battery.

The formula is ampere-hour=(total load * required time in hour)/battery voltage

Inverter Connection Diagram

The circuit diagram for an inverter connection at home is given below. According to the below circuit diagram you can see that during load shedding Light 3, fan and T.V can be run by the inverter. According to your requirement connect the load to the inverter. As the Neutral is common for all loads you did not need the neutral connection from the inverter individually.
