Digital Ups
​
Most may tend to believe that an inverter is just the same as a digital UPS, but that is not true. Although both, an inverter, and a UPS, perform the same task of converting DC to AC, the switchover time taken by a Digital UPS (approx. 2-3 milliseconds) is much less than that taken by an inverter (approx. 500 milliseconds). While this time delay may not matter much to us, it does take a toll on devices like computers, printers and a few others.
To explain further, Digital UPS use Digital Signal Processing (DSP) techniques which convert the waves to Pure Sine waves instead of Stepped Sine Wave or Square Wave, a technology which is found in older models. Pure Sine Waves provide a constant, uniform current to devices that enable them to run on full supply. E.g. appliances like motors, refrigerators, fans and televisions will only perform well when supplied with Pure Sine Waves. Any other wave form will cause disturbance in the functioning of the device, thereby damaging it.
V-Guard Digital UPS models span a range of 300VA to 10000VA.

A lot of inverters are equipped with a lead acid battery which is extremely powerful and provides a very good power supply. But like they say, everything good comes at a price! Lead acid batteries have a short life-span and are high-maintenance. On the other hand, those batteries which are sealed and maintenance-free have a high initial investment cost and a shorter life-span making them not a wise option either.

While weather is something that is not under our control, we do depend on electricity to control our surrounding/indoor temperature and make-up for the unpredictability of the weather.
The one catalyst that plays spoilsport in the Weather-Electricity equation is power supply! Just when you need that fan or that heater working, the power goes off leaving you to deal with the weather all by yourself.
