[OT] UPS / Dry Battery / Generator / Stabilizer etc Buying advice and help.

[murtaza12]

Well looking at the load, your load is indeed less, all your equipments are DC powered equpiments and they require very less electricity consumption.

The size of the battery is determines the duration it will work. SO if you would be using 165AH battery, then it would last longer than a lower AH battery
A small definition what AH means is the Amphere hours. If you draw one ampere from this battery, it will work for 165 hours before discharging completely. If your load draws 2 amperes than your battery will last (165/2) = 82.5 hours

Usully 165 OR 150AH are standard batteries that are used. However, the next in line is 120AH. If you load is less than you should probably go for 120AH battery. But dont go for lower than 120AH ones. They are very small and i have never seen these smaller batteries with UPS.

Also, every size battery has a required charging amperes and they are mentioned here
http://www.exide.com.pk/Products/Automotive/Range/specifications_of_Exide_Automotive_Batteries.pdf

Now check with your inverter how much charging amperes does it provide (i tried googling but didnt help)
If you oversize the battery than your inverter has chances of being damaged, due to longer charging times
If you undersize the battery than your battery life is compromised as higher charging current will degrade battery life.
So its better that you select battery that is neither too big and neither to small.

120 to 165AH should be good. 165 is almost same as 150 so dont bother in between these two

Can I go for a 120 AH battery then?



My inverter has a 15A and 20A charging option.
I read in the users manual that 15A charges slower and prolongs the overall life of the battery.
20A charges faster and will reduce the life of the battery in the long run.

So if I buy a 120 AH battery, can I use it on 20A charging mode?

Yes you have read it correctly. faster charging reduces battery life

From the exide battery chart, the required charging amps for 120Ah battery is 12Amps. You will be providing it with 15Amps which is already slightly higher. Hence using 20Amps on it is not recommended at all

However, the 150AH battery has required charging of 15Amps and it can safely be used on both 15 and 20 Amps (15 recommended as it prolongs battery life)

Which one do I get?

Get Servo one.
Thats what you should use on Computer.
Not the normal ones since, for some magical reason they degrade your psu or something i think.

For 2 to 3 fans, one led and a ps4 1.5 kva / 1000 watts UPS will be enuf ... sinewave inverters are meant for lite fans only ... thy surely damages the electronic circuitry ... so never use a sinewave thing with led lcd pc or projector ...

Questions:
1. Is it possible to power a projector on a UPS?
yes u can use projector with a ups provided its a pure sinewave one


2. What power UPS should I get? I've heard Homage is reliable.
1500 va or 1000 watss ... homage is again an inverter so dont use inverter at all

3. How many batteries? What brand? What type?
a 1000 watt ups takes 2 batteries to run ... if u r using local made liquid battery thn buy AGS 165 OR 175 ampere and if u r going to buy dry cell thn NARADA is a good brand and its 100 ampere or 155 ampere is good ...


4. What will this setup cost?
APC is an american brand and is easily avaiable in market in used form ... new box packed APC is very much expensive so here people are using its used one for their home thing ... some people here in lahore are giving one year warranty with used one ... i m using used one too ... APC is a puresine wave ups is pretty much reliable ... i dont no wot price its being sold nowadays but its an idea that it comes between 18k to 25k depending on warranty period ... for local battery u can ask any battery shop for ags brand ... as far as dry gel battery is concern NARADA 100 ah ll cost u 25k and 155 ampere ll cost u 36k ...

i purchased it from johar town lahore .. their office number is 04235951495 and cell number is 03214997060

I talked to my electrician today. He said the 750Watt Homage Inverter that I own will be perfect for hooking up the house to and will power my PS4 and all electronics. I wanted to ask you why you stressed so much upon NOT using an inverter. Please let me know asap. Thanks.

Allow me to step in.

All UPS devices are inverters so warning to not use inverters is slightly inaccurate. What he IS talking about is not using modified sine wave inverters. The electricity you get from Wapda is a silky smooth Pure Sine Wave. The sine wave produced by inverters like homage et all is called a Modified Sine Wave (which is not a sine wave at all and actually some derivation of a square wave). This modified sine wave tends to lower life of capacitors and therefore electronics - but over quite a long period of time (think years).

Pure sine wave UPS do exist (a cheap example is a second-hand APC UPS) but usually tend to be very very pricey. A 750Watt inverter would be the bare minimum to run a PS4+TV and a few lights and fans. You will need to couple it ideally with a 190AH+ battery for a 2 hour backup time for a year or two (backup time deteriorates over time).

Alternatively you can go with a 2000 VA ( generally 1350 Watt) UPS with a dual battery system for a much more reliable back up option (but a bit more pricey).

 

[muhammad bt]

Thankyou very much! I just need the inverter to keep my PS4 powered on till I shut it down properly. So 10 minutes of backup should be more than enough.

dear don b too stressed . i only told u wot was gud 4 u ... just hook up ur inverter n start using ur load with it ........ if u face problems thn change it otherwise u r fine with ur existing setup ..... therez a APC company in johar town who deals in used n new APC UPS .. just give them a call n ask them y APC is better than any inverter and also tell them ur load that u want to run on inverter ... their contacts r 04235951495 / 03214997060 ...

UPS settings

Does anybody know what the Wide and Narrow switch on a UPS is for. From what i read on the internet, it should be in narrow mode to use with a TV, Computer and Electronics. Any help will be appreciated.

UPS running on Generator

Salam brothers
I have a ups which does not run on generator electricity, i mean i want my ups to use battries when light goes but when i start the generator it should stop using battries power but my ups is not doing this maybe my ups is not compitable but if there is any way i can do it please help.

here is the link of ups and generator is 3kva

I have limited knowledge in this, but I did solve this problem for myself some time ago.
Here's the problem; the electricity a generator produces isn't stable like WAPDA. Therefore some UPS have trouble properly adapting to a generator produced electricity. It could be the voltage(too much/too little/inconsistent) or could be the frequency(50/60Hz) or the difference in power/VA-KVA(volt ampere;generator is low, ups is high). Or something else that I can't think of right now.

Last year when my generator wasn't turning my UPS to charge, I went ahead and bought an expensive servomotor stabilizer. But it wasn't to fix this issue. Bought it to invigorate the inferior voltage that was coming from wapda those days(around 190 volts) and hence the batteries weren't getting charged.
Coincidently with the introduction of that stablizer between wallsocket and UPS, the wapda charging improved(of my batteries), but also as a byproduct, my generator started to charge the UPS.
However your case may be entirely different to mine. So my recommendation is to read this post, but don't go for my solution.
Consult a proper electrician as I am not one. Just a hobbyist.

Good luck.

This year i m not running my generator at all. Hence my ups is behaving very well and not giving any issues of charging or tripping or software issues etc.

I have been told that those who run ups on generator get alot of such problems.

Lets see. This is just my experience duting 6 months since i bought new ups and also did not run it in generator at all.

You need to adjust (while the gen is under load) the voltage if it is too little or too less. The voltage regulator is under the casing of the dynamo and has a screw on it.

And the frequency by adjusting a screw that controls the rpm of the engine.

Can we to use ups for charging a car's battery

 

[Lord Ammar]

Are you sure the switch that your UPS plugs into is connected to the generator?

Buy a separate charger it will be much cheaper and easy to use. Last time i checked it was 1500rs.
