tnx
@ceejay80 for the idea, i just finished installing d fan, d fan runs like am using normal inverter with d humming of d fan.......d fan dey blow like.............

ceejay80:
When u open the ups ,the fan should be in front , the fan should face the transformer, after connecting the fan to the capacitor, put it ON to know where the fan breeze is coming out from , buy gum for gluing shoes and rob on the fan, rub the gum again on the ups , let the fan sit on top of the gum on the ups and hold for a while for the gum to dry, make sure the fan is facing the transformer, test it by outing it on the ups before u cover it,
Don't buy small cooling fan or fan bigger than the ups, u can take ur ups there and get a matching fan, the fan should sit comfortably in front of the ups panel

tnx bro. will definitely do as u instructed

ceejay80:
It should be blowing directly to the transformer

tnx bro...i want to go get d fan now sumtin came to my mind, will d fan be glued by the side of d transformer or front? if it were to be d side definitely there won't be space do mount the fan and screw the cover of the ups.........don't mind me.i do ask questions when i don't get it.

ceejay80:
there's a big 12v capacitor in ur ups ,its the biggest capacitor in ur ups, it has two legs, one leg of it is connected to the black wire that is connected to the battery(-) ,trace the capacitor legs connected to u ps and find out where they lead to, like I said one leg leads to ur battery (-) which is the black wire and that's where u will solder the black wire from the fan to, the the red wire from the fan is soldered to the other capacitor leg, if u connect it the other way road , then that fan is damaged for good, after u hv connected ur fan switch on ur ups and find out which side of the fan the air actually come out from, face that side to ur ups transformer and glue the fan in the ups so that it doesn't fall, now cover ur ups and screw the bolts,
below is how a capacitor looks like , but in the ups , it the biggest 12v capacitor that its connected to

cool....i know how to use soldering iron well,i know cap very well....lolzz. ..tnx bro..

ceejay80:
This is the cooling fan i'm talking about, it has to be a 12v fan, even if it has 4 wires ,all u need is the black and red wire, in oshodi u can get this size for 200naira but in other market its 500naira, these fan has different sizes and voltage, don't buy the small one for ur ups, there's one that will actually fit in ur ups and the u can cover it, nobody will know that there's a fan inside, if u can't install it , give it to an electrician, they won't charge u more than 200 or 500 hairs, these cooling fans has two sides,
Air comes out from one side but air doesn't come out from the other, the side that air comes out from should face the transformer

tanx bro....i should be able to do it myself......u actually mean the air of d fan should be blowing directly to the transformer shebi?.

ceejay80:
to the bolder post above....
There is no fake bluegate ups, if it overheats ,its because its overloaded, bluegate ups comes in different models just like cars and lcd tv....there's actually one that beeps for 13 and 17 times and then goes into silent mode , have u seen the brand new latest blue gate ups ? Urs overheat doesn't mean its fake, I bought a brand new mini amplifier that overheated and burn out the sound ic , I have changed the sound ic 3time before I neatly installed a small fan in it ,u won't even know that there's a fan that cools the transformer and sound ic in it, till today its working flawlessly
If u have a stabilizer u will notice that there's a cooling fan in it, it doesn't mean the stabs fake, even computer cpu has cooling fan installed near the transformer ,most transformers has cooling fan near them, I will teach u guys how to install cooling fan to ups that overheats,
Out of all nairalanders I help install their mini inverter ,only 2 had the overheating problem, I have installed fan in them and they don't have any problem

ceejay abeg show us with detail pix..tnx

JUO:
No need to fight please. We are here to learn. How do I wake this battery, the owner used acid on it?

wow acid!!! chaiii... naijaaaaaa lolzzz.

adanny01:
Even if those some people claim they know everything, i know that they dont.

mr @adanny01 you don't have to take what I said as a weapon against another nairalander........i don't fight or like to argue online......i commented abt some guy having 4 ba3 bar blinking ish some times ago and you see i backoff...not becuz i totally agree but i don't argue online.
also this mr @chris81964 you are talking about is who i can call a professional installer in solar power (chk diz page u will see some of his recent installation www.nairaland.com/390522/solar-energy-complement-fta/126) ....he had knowledge in this system so i don't know d boss or who is right....my point is what i said abt knowing everything,isnt about him...... i just talked generally.

chaiiii battery bank calculator guys dey here ooooo...oga pass oga 4 nairaland.....everyone always proof they know something,some claim they know everything.God go help us

adanny01:
I get the angle you are coming from.

Dont you think that even before going to the field to start testing you got to do the maths to know if there is a deficiancy in the system. In this case how effective is a 20A charger mated with 2 220Ah battery bank. Not matter the testing, the charger cant produce more than the 20A it is rated which will naturally take a long time to charge fully. If the maths is right at 22hrs that means he needs a full day of charging with public supply at atleast 200vac and 50hz non stop.

You need to ask him if he had had that kind of non stop charge to be able to get that full. If he never had, its not so easy for him to experience that full charge.

Some of what i have said before comes my personal experience with the same inverter. I know how it behaves. For instance, when the inverter has fully charged to the extent it no longer flashes the 4th bar and grid power supply fails for 2 seconds and returns which mean the battery mode has been entered and exited, the 4th bar will start flashing like its charging. Its going to flash like that for another 30mins - 1hr before it shows full charge again. The question is, did the 2 secs discharge (even with no load) of battery replenished by 30mins of charging? I dont think so. What i think is that it reenters floating charge which will keep the inverter charger in that mode for a while.

Secondly, i sometimes usually know when my inverter is charging on floating or bulk. This i know when we have low voltage of around 100vac from grid or when using generator. When using generator i hear the change in generator sound upon putting load on it, i know the charger is in bulk stage but when no load is felt by the generator i know its on float. I use a 1kva stabilizer to charge the system so when we have low voltage in grind and the inverter is in bulk charging, the stabilizer heats up real bad. But when voltage is above 160, it charges well without me knowing the stage.

I have watch the inverter well thats why i feel its the set up that is incapacitated.

all Good,i agree with your point yea.......

adanny01:
What do you suggest?

If his 20A charger will not do an adequate job, dont.you think he should go higher?

If he gets say 120vac from the public supply, dont you think thats the more reason he needs a better charger.

Am also learning.

if he had to call an expert to check on what the problem is, The expert will 1stly check the SOC of the battery with a good DMM. that will show whether the battery is still charging on d 4 bar blink or it d battery is on float charge.........my point is There isn't surplus cash in average Nigerian to invest on these inverter stuff u know...what does he gain if he should get 60amp external charger n it doesn't increases his backup?

adanny01:
My guess is you have 2 of those batteries which is 440Ah.

Mercury 1.2 and 2.4kva both come with 20A charger. 440Ah÷20A=22hrs

So you need 22hrs of constant grid power (NEPA) to charge fully.

The charger is simply inadequate for your battery. You can purchase an external charger of something like 60A or better still 80A

440/60 = 7.3hrs or 5.5hrs with an 80A charger.

most calculation doesn't work in real life......if u av experience in solar, inverter battery installation u will know what i mean... lol seriously 60/80amp is a wash also do u think a 200ah ba3 would provide 200amp straight? or yr 60 amp charger will pull accurate 60amp from the grid? lolzzz. how do you account 4 a public supply grid producing 90~120vac which is even fluctuating the voltage?

yahyamay:
putting the charger nob to 80-100 reads charging at 18amps. tho my battery is below 100ah

that means if the nob is at highest it would be reading 20 amps

cool tnx bro

ceejay80s:
Never noticed it, all I do is just charge or sometimes set the nob to 80-100ah or sometimes higher since my batteries put together is 160ah

plz let's knw d max amp readed wen next u recharge.tnx.

ceejay80s:
Ours is a different model, the smart charger seller has something similar to this, I chose mine cos its metal casing, this one with digital screen is plastic
Our 20amp is model MA-1220A

okay...does d amp meter needle incorporated in yr charger ever reads around 20 amp while charging?

20amp charger might be pulling less current than you think guys........here is a full review/teardown of suoer charger with pictures http://quan-diy.com/misc/scc/suoer20.htm
@ceejay80s keep up d good work!!!

mr ceejay. abeg shey yr 10 watt fan is powered by a. c or d. c power source?

kiekie1:
Happy Xmas Bro. How have you been ?

i wish u dsame, am doing fine.

mr frankie is probably not the type of dubious person he is very prompt with delivery,i sent almost half a million naira to him without knowing him in person....u wont bliv i got my goods d following day
i dont knw d prob but, i know he is going to deliver 4 sure and dont tink hez running away with yr money alot of people know him n do buisness with him n infact most people avent meet him in person.....u can count on him.

adanny01:
The both of you temizeee and Konnektions146 should prove what you know from the quote below.



True or false?

hey baba nla
2v 500ah battery of 6 pieces is approximately 6kw bro. u can only use it with inverter in series which makes 12v at 500 ah..... diz are simple basics of battery configuration.....see bro all diz wiki research doesn't help most time...they will only confuse you. #wekeeplearning

adanny01:
I dont think i mentioned current in my comment neither is it my context. Current in this case relates only to charge capacity of the inverter or external charger.

I will like to be practical, i have only seen inverters of 12v and above.

If samnaija has 2v batteries then he needs a minimum of 6 batteries in series which is exactly the configuration he has.

The matter i stressed is the Amp-hour (Ah) rating of his batteries and the total for the bank. Lets define Ah.

Wikepedia says Ah is a unit of electric charge, equal to the charge transferred by a steady current of one ampere flowing for one hour

Using that, if 1 battery of 2v has a charge capacity of 500Ah as claimed by samnaija, how much is the capacity of 6 batteries connected together? Whether connected in series or parallel, they all get charged by the same charger at the same or almost the same current. Are you saying that all of them cannot store up charge of more than the capacity of 1 battery? If thats the case, whats the point of connecting batteries together, he should have just gotten 1 12v battery.

Every battery holds its charge and contributes to the whole bank. If he really has 6 500Ah batteries connected in series or parallel, his bank capacity is 3000Ah.

Please i may not be an electrical engineer but i know the difference between current (A) and Amp-hr (Ah).

lwkmd ooo.... my oga it is true u are not electrical engineer ooo...... @ALL he is trying to say wattage of d setup either in series or parallel not amp rating....lolz

I have an idea of building simple 12/24v pwm solar charge controller using relay n diodes only.. . I already practice on vero board n it works really great, do u think it worth marketing guys?

Hmmm... nice one, nice invention here. But i bet you will still need the real one, the real one has more power than yours, apart from pcb u might need to drill a plastic casing for your project. you will need bits of different sizes for different jobs.

for a start, well...your invention will do but for more professional jobs, you will need the real pcb drilling machine, a big 650W drilling machine, a jig saw etc.

sure thing #noted sir

thanks oo oga sportsmaster n princejude
..i was able to design my own pcb drill(electric)
materials n cost are;
6v electric motor(#100)
ordinary pen refill(you know how cheap this would be)
4 minutes epoxy(#200)
drill bit i used 1.0mm(#40) i spent less than #400 to build it. i will buy more bits later sha.....will upload picture on a free day.(v.busy at school). I was suprised because it drill pcb really fast n easy.....it very easy to use n handle because of its portability....i power it with USB power supply.

sportsmaster:
electric hand drill

okay sir...but do you have any idea about the non-electric ones(manual hand drill)

sportsmaster:
2k-3k.

but did yu mean d electric type or manual hnd drill?

sportsmaster:
2k-3k.

thnks bro

oga nisol, please how much is hand drill pcb n do u av idea of wea to get it?

please house i need hand drill pcb how much can it worth in d market?

please house i need hand drill pcb how much can ot worth in d market?
