Points To Know & Consider Before Purchasing Your UPS Or Inverter. Read It, If You Are Planning!

If you have decided to purchase an Inverter or an UPS, than here are the factors which you should consider, check or ask to the UPS or Inverter vendors and clarify or tell them to explain the points. These are the points you should know or check before buying and UPS/Inverter.

First of all you should know the meaning or the definition of an UPS and Inverter. UPS means, and Uninterrupted Power Supply of electricity. Means the shifting time (delay) of your load (equipments) from mains electricity supply to the battery supply should be very-very less, that’s why it is called Uninterrupted; there is no interruption of electricity to your equipments. There are two types of UPS, mainly known as 1) On-Line UPS and 2) Off-Line UPS. Brief explanation of an ON-Line and Of-Line UPS: Microtech_Inverter_UPS_HomeUPS_(TheZeroLife.Com)

1) On-Line UPS is continuously regulating your mains supply than charging the batteries than again inverting the battery DC supply into AC supply and supplying it to your load. It means it is continuously inverting the DC into AC without any physical change over from mains supply to inverter through any physical relay switching; thus it is called the On-Line UPS.

2) Off-Line UPS use to change your load from mains supply to inverter supply, and switches ON the inverter after the failure of mains through physical relay switching. As the mains supply is present it use to charge the battery and as the mains supply fails it immediately switches ON the inverter and starts consuming the charged battery. Thus it is called as the Off-Line UPS. The switching delay of Relay from mains supply to battery-inverter supply should be very-very low (less than 10 ms), otherwise the PC you are using as a load to the Off-Line UPS, will restart (reboot) and will be of no use to the PC.

What is an Inverter? Why inverter is different than UPS?

Inverter is an electronics equipment (device) that use to convert or invert the battery supply in to an Alternating current i.e. DC (direct current/battery supply) into an AC (alternating current). Today the line of difference between UPS and Inverter is invisible. Today it is difficult to find out the difference between UPS and Inverter.

But you can imagine little differences like, the Inverter do not gives or not designed to give you pure Sin Wave output or Cosine wave output, because your electrical equipments like TV, Fridge, AC (Air Conditioner) do not need pure sine wave ac supply, that’s why Inverter is required to run these equipments, also Inverter is little cheaper than UPS with the same watt (load capacity) output. You can also say that the changeover time after mains failure to the DC (battery) is very high, compare to UPS.

As per the market requirement technology has changed and people are mostly going for the hybrid technology that is UPS + Inverter technology. Means today in the market it is wise idea to go for the device which can act like an UPS as well as inverter (considering that in feature you will buy a computer or laptop). In short UPS is more superior in technology than inverter and can work as an inverter too……. so why not to buy equipment which can work like UPS and Inverter both with the average price of UPS and Inverter (price little higher than inverter and lower than UPS)?

Points to consider while deciding for UPS and Inverter, clarify/consider it before purchasing your UPS or Inverter:

1) Do I need an Inverter or an UPS as per my requirement or use? I don’t want to upgrade or go for another purchase after 1-2 year (after very short period), as my requirement will change, or as the technology will evolve.

2) If I wanted to purchase an Inverter, which type of inverter I should go for or will suit my need/requirement, inverter with the sine wave, square wave, or cosine wave output?Inverter_UPS_HomeUPS_(TheZeroLife.Com)

3) What will be the power output in Watt/VA for my Inverter or UPS, if I decide it to use for my home appliances like CFL, LCD TV, Cooler, Fan, AC, or if only I want to use it for my computer/laptop.

4) What will be the battery size, battery voltage, battery maintenance requirements etc?

5) Which type of battery I should go for Normal/standard battery, Tubular battery, or SMF (Sealed Maintenance Free).

6) What are Watt and VA ratings in Inverter and UPS.

7) How to calculate the battery backup in Hours, and battery capacity in AH (Ampere Hour).

8) How to use the Inverter or UPS to extend the battery life and Backup hours.

9) What will be the wiring changes, I will have to do to my normal electrical wiring, and who is going to do this.

10) What will be the visiting charges of the UPS/Inverter engineer for any complain, what are the possibilities of failure and there charges? What are the warranty/guarantee terms and conditions, and what are the parts covered till how much time.

11) What are the AMC (annual maintenance charge) and the parts covered under it.

12) What protections & Indications the equipment (UPS/Inverter) is using like, over load protection, Battery level indicator, Load display, what is the low battery cut off voltage, no load shut down, short circuit protection, reverse battery polarity protection etc.

13) What will the safer place to keep my Inverter or UPS at my home?

14) What are the safety precautions should I take for children at home and to avoid an accident.

The above all points you should consider or keep in mind or ask to yourSukam_Inverter_Sukam_UPS_(TheZeroLife.Com) UPS/Inverter marketing person before purchasing your Inverter or UPS.
