Frequent power outages have become part of our daily routine, and we rely on a UPS or inverter to deal with them. But do you know the difference in the way they work? Many people still do not understand the difference between an old UPS and a modern “sine wave” inverter.
​What is a UPS?
The primary job of a standard UPS is to provide power from the battery immediately after the electricity goes out.
Limitation: Old UPS systems often produce “square waves,” which can be harmful to fans, motors, and sensitive electronic devices like computers or LEDs. This causes fans to heat up and makes a ‘buzzing’ sound.
​Modern Inverter Technology
The inverters available in the market today are very smart and efficient.
The biggest advantage of a pure sine wave inverter is that it produces the exact same current as WAPDA’s electricity. This makes your fans, motors, and other appliances work exactly as they do on mains power.
Energy saving: Modern inverters have very efficient circuits to charge the battery, which increases the battery life and also reduces the electricity bill.
​Which system should you choose?
If your budget is low: You can look for a “sine wave” UPS from a good company.
If you want comfort and long life: A “smart inverter” is the best choice. It is definitely more expensive, but it increases the lifespan of your expensive appliances and does not even let you feel the electricity go out.
​Tip for best performance
If you have installed a solar system in your home, remember that your inverter should be “hybrid.” A hybrid inverter decides itself when it should take electricity from the solar panels, when from the battery, and when from WAPDA. This technology is the most economical in today’s era.
