Aslam o Alaikum All !

This is my first post on pakwheels. I need to know your valuable advice over the purchase of UPS.

I need two fans to work during load shedding , mostly one fan can serve the purpose. At least 6 hrs continuous.
Two to three energy savers.

I also viewed a 1000 wt generator with Gas and petrol option. That costs Rs. 10,000/- Will it be a suitable replacement for ups of mentioned capacity??

I am blank in both UPS and Generator. Will you plz share your views what I should go for? If UPS then which one? if generator then which one? I need durablity and reliability.

Kind Regards

Zain

I will suggest you to go for UPS instead of generator, 3 months before i was also confused then a friend of mine suggested me to go for 1200 volts UPS along with 190 AMP battery, I have connected the UPS with all rooms,kitchen,washroom,tv lounge, its works flawlessly and costed me 22k along with fitting. we run 2 fans and 3 energy savers anytime and some time 5 energy savers, but dont know exactly backup time as here in peshawar there is loudshedding for one hour not more then that.

walikum us salam brother
first of all welcome to Pakwheels
there are two types of UPS available in market. Local made and branded/imported. In my opinion you should go for branded or imported one. Following are some points which you should consider before finalizing your decision.
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.

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.

My Financial assement
Assumption.
Heavy load like AC, Pumps on Utility(Kesc/Wapda)
Conclusion
If one can afford should invest on solar as much as possible.
For lower middle class use solar basic package of 1 fan and light rather then UPS.(RS25K 2013) to support our country out of energy crisis.
