Invert-er are becoming very common these days especially in india where there are lot of electricity cuts so in that case it is necessary to buy the right sort of invert-er. Before setting out to buy an invert-er for your home, it is always best to know before hand the through estimate of your total power consumption. Appliances that we use around our homes such as lights, bulbs, refrigerator, air conditioners etc..
All are the ones that consume power and hence are rated in watts. invert-er capacity is directly proportional to total load that you want to support. The invert-er capacity is measured in volt ampere, (VA). VA is actually apparent power and is the product of the voltage and the current supplied by the equipment. The invert-er capacity is measured in VA and battery capacity is measured in WA.
A we discussed earlier invert-er converts DC how to AC current. But depending on how the AC current looks like, the inverter’s are classified as sine wave or square wave invert-er. It is always good to have sine wave invert-er even though they are costly for the sake of safety and longevity of the appliances. The famous invert-er brands are Luminous, Microtek, Exide, Apc, Sukam. Most of the brands also sells the battery along with the invert-er. It is good to buy the combo as you don’t need to worry about the compatibility.
