Notes: Inverter purchasing calculations for home

 Take a list of items that will run in inverter like 2fans, 1 LED tubelight, 1 laptop, 2 LED TV, etc Now calcullate sum of their power e.g 2*60+1*20+100+2*100 WH=440 WH Now add 25% to above power sum e.g 440*125%=550WH Then multiply it by power factor (most case it's 1/0.8) e.g 550/.08=687.5 WH For every inverter has its own effeiency say 90%,80%, etc Therefore, inverter power that has to be purchased = 687.5/90%=763.888 VA Above is how to calculate inverter power that has to be purchased. ---- Now comes how to choose battery power Batter power (VA) =  Home Load * Backup (hrs)/Battery Vold = 687.5WH*2hr/12amp = 114.58 --- This is how you do calculations for purchasing invertor ========================= Bibliography
