UPS Buying Guide [Pakistan Focused]

The issue of UPS (Uninterrupted Power Supply) has already been discussed here before, but we thought of adding more information to what we had already said.

Market dynamism and product innovation always fill the stores with improved and new versions of various products every now and then. Anyways, this dynamism does not change some of the basic principles that may be important to consider before purchasing inverter with Backup Battery. We will try to cover some of new salient points in this article post.

The usual trend prevalent in market regarding UPS offer is like, 2 Energy Savors and 2 Fans (May be 0.5 KVA UPS required) and list goes on and on in combinations of energy savors and fans.

Planning & Installation:

  • Place of installation is extremely vital and logically installation of UPS should be placed near to the place of Main Switch board – it will help you get the main supply into UPS and output from UPS to home appliances easily. [May be you need an electrician to fix the wiring for you, in case you are not good at it]
  • Make sure the place where UPS is installed is clear of barriers of any time and proper ventilation is available.
  • Make a list of the electrical equipment that you will connect to the UPS – and make sure you communicate this list clearly to the electrician to avoid any confusion later on.
  • If possible, calculate watts consumption by electrical equipment, this can be done by referring manuals of electrical equipments. Power Management Expert may be consulted in case manuals are not available.
  • For calculation basic formulas can also be used like : (VA)Watts = Volts x Amps

UPS Purchasing Pattern:

  • If planning and calculation is done, then next step is to research the complete Electronic UPS market for prices, quality and warranty. You will notice that price difference could be a factor depending upon the UPS quality and brands.
  • Consider parts replacement and service warranty in UPS with warranty offers. Also compare UPS of different brands.
  • Quality of UPS can be determined by its make, heat dissipation and parts used during the development of the UPS. For this, you may have to refer manual or probe to seller.
  • Keep notice of Battery Recharge time.
  • Check if UPS is capable of alarms and LEDs (small screen showing information about UPS and battery health) that indicate battery low or wiring issues (if any).
  • If you are purchasing a local brand, then make sure the seller will give you 2 days money back warranty – in case of bad backup time or any other problem.
  • In case of local made UPS, make sure that you learn the wiring pattern, i.e. to connect red wire with positive terminal of battery and black with negative terminal of battery. Get these instructions in-written form from the seller – and practice them only after consulting the written instructions.

Battery:

  • Same it goes, with the battery unit. Please note down a simple formula, the higher the amperes the longer the back up time. Like, if you purchase 150 ampere battery on 1 KVA UPS, it may give you 3-4 hours of backup time on 4 savors and 2 fans. Provided battery is new and battery condition is reasonably good – this backup time will reduce to half if battery power is 75 ampere.
  • Once you purchased the battery, inquire about its charging status. If it is fully charged then install it with UPS and avail the facility. But if it is not charged, then get it charged for few hours from the same outlet or in home [usually 3-5 hours of charging is enough]. But battery must be completely charged before connecting with UPS. Otherwise it will not be able to provide its performance and chances of dead Battery Cell may arise as well.
  • Place the battery in well ventilated environment to avoid any unforeseen situation.
  • Try to buy fresh battery instead of old, inquire about battery date from seller or you can do it yourself as well if you know the trick. The date is defined by 2 digit code with one number and one letter. For example, c8, this may mean Mar 2008.
  • If you are buying local batteries, you can also check their details on their OEM websites. Like, for example, Volta Batteries have complete detail about their products on their website even separate for UPS.
  • Buy a car battery with high reserve capacity.

Conclusion:

If UPS is completely installed , it needs your attention for checking its indicator and information on LED screen if not daily then may be every second day to check battery charge status, wiring status and some other options depends on the UPS features.

    The battery situation is lot more complicated.
    First its 150AH not 150 A. Big difference. 150AH is the capacity of the battery @ 20hrs. So a 150AH will give you 7.5A for 20 hrs.

    The rule of thumb is that if your discharging your battery in 1hr then the capacity of the battery is halfed. It now behaves as a 75AH. This is a very common mistake people do with battery sizing. “The capacity of the battery decreases if you are discharging it at a faster rate”.

    The battery manufacturer should provide you with a chart showing you how the capacity decreases with disccharge rate. But our local battery manufacturers don’t provide you with such information. Hence the miss information.

    Well I thought this article will discuss about whith UPS is better, chineses imported or Local manufacturers. and Which one uses battery effectively.

    what a perfect guide…got homage fr myslf…awesom it iz…

  • Mujeer

    The KVA to Watts conversion also takes into efficiency factor and for UPS it can vary from 0.4 to 0.6 (quality and type e.g block, sinal etc.) Hence as a general thumb rule a 1 KVA UPS can take a load of 500 Watts (assuming 0.5 efficiency factor).

    One thing to add to a UPS is a Battery Desulfator. While charging and discharging, sulfur crystals develop on battery plates. This reduces their usable area and also reduces the gravity of battery water. The device is a simple electronic item that generates electronic pulses, when the battery is charging, to break these crystals. This maximizes plate’s usable area and restores gravity of battery water. This is no magic device, I have been using them for three years in UPS as well as in my car and in general the battery life is increased by 50 – 100%. A Taiwan made product is available at Zubair Impex, Tibet Center, Saddar Karachi (Shakir 0321-8222686). I first imported 10 of these and since then have helped this vendor import many more. We have received very positive feedback so far. A DIY version of this is also available at http://www.courtiestown.co.uk

    hello there salam.

    you are just LUCKY to be able to say that your experience with Homage ups is good. Mine was horrible, like many others out there.
    All you know that these are made in china , so if they really work that would be a sheer good luck.
    I bought a Homage ups from saddar karachi . The sales man boasted so much about that is better than the rest of the flock. I foolishly beleived him.
    After installation it workd only for hardly 3 months, that the problems started to surface. Once the problems started arising in this thins they will never stop. The reason is its circuit board is machine made, hence very minute soldering is done on it. The local techies at homage service centre cant just fix it. In just one year this bloody Homage UPS ruin 2 of my batteries. They all become swollen, which is a sign of Overcharging.

    The other thing i noticed that i was not the only peroson, who is troubled by this cheap bloody thing. I saw many other disgruntled customers at teh service centre who kept on bringing the same problem over and over again. in just one year i have to take it 3 times to the service ctr all by myself. And all these 3 times they returned it after one week or 2. thats a lot of time which clearly shows the huge complains they were recieving.
    and when the fourth time i took it to the service ctr, they told me that since the plastic body is got melted from the corner of a UPs , (slightly) so the warranty has been void and they cant repair it. By listening to this Bullshit , I smashed the UPS on the floor of their workshop and left.

    Later on i bought a locally made UPS from the same region . This time i was carefull. i insisted on one week money back guarantee and free home service. they agreed by adding another 1 thousand in the total cost.
    this UPS of mine (CLAssic Ups) is working since 2008 . i have no troble with it so far.

    My advice to all is to not to BUY these chinese crap. They are toy ups.
    Be WISE , look into your neighbourhood , what ups are they using , what are thier experiences with it. and then take a decision . Always buy it with home service guarantee, even it costs a little more than usual.

    sincerely
    dr.dan

      “I smashed the UPS on the floor of their workshop and left.” ….Thug life….Badass thing you did ;)

  • shahzad Khalid

    After sale service is very pore of Homage battery and inverter in Pakistan by R&I company. R&I have staff is not cooperative for any complete. I suggest for all people you select the local UPS and other batteries. I have wrong decision of purchase Homage battery and inverter. my com.My compliant N#.4004-LHR-630 by date 17-7-2010 . I have purchased from R&I Pakistan. I face problem with in two month.

  • ups

    PC takes about 400W maximum, LCD 60W, PS3 400W again maximum.. A couple of modem and speakers total ammounts to around 900-950W so i guess 1000 should be enough.

  • K. Shahzad

    My experience with homage is going good, I am using 2kva version from last 3 years and found these ones actually better than the local made ones, recharging is also real efficient and fast.

    I have replaced my batteries two times, but the issue was that I didn’t checked and filled the battery liquid when it had to be. So you will need to check that real regular in case you don’t wanna ruin your liquid batteries.

    Generally if its homage or any other Chinese brand of same category, they are all better than these local made UPS.

    A new product has just come into the market with extreme innovation which i have not seen in any other product. It even tells u the malfunctioning part in case of any problem plus it also gives u a warranty of 1 year with excellent aftersales service. The product seriously is state of art i have heard that it is developed by some professor from MIT and being locally manufactured adding the advantage of excellent aftersales and upgradations. Dont waste ur money on third class chinese products and Pakistani resellers of chinese products. Its brand name is DUNAMIS.
