Calculate Battery Back-up

To calculate the battery back-up one should know the AH (Ampere Hour) rating of the battery. Incase of mobiles it is MAH i.e. Milli Ampere Hour. Usually this rating is mentioned on the nameplate of the battery. "Ampere hour" rating means that battery can supply the power to the load at the mentioned ampere hour rating for one hour continously. Let the "AH" rating of the particular battery is 20. Then, if the load connected to the battery is 20 amperes then battery back is 1 hour. If the load connected to the same battery is 5 Amperes then the battery back-up is 4 hour. Formula : Battery Back-up = X/Y hours where X= Ampere Hour rating of battery Y= Load current in "Amperes"

3 Steps to Choose Inverter

When your power supplies blows off then it is the back-up power supplied by inverter which runs your equipments. In order that your inverter function properly; the selection of right kind of inverter is very important before installing it at your premise. Here are the three steps that will help you in installing proper inverter at your premise: STEP 1. Choose only "Pure Sine Wave" Inverter instead of "Modified Sine Wave" or "Square Wave" Inverters.This will ensure that your expensive and sensitive electrical & electronic equipments like fans, computers, refrigerators,TV etc. function properly without any noise or overheating. I personally feel "High Frequency Pure Sine Wave Inverters" are better than "Low Frequency/Transformer Isolated Inverters" as they are cheap and less bulkier. STEP 2. In inverters, always select "Tubular/Marine/Deep Cycle" batteries instead of "Automotive" batteries. "Tubular/Marine/D...
