16-17k or there about, but they are not brand new but grade 1, what do u intend loading?
Brand new 100ah should around 50-100k

keally:
. Guy, pls giv me ur no so I can call on U for assistance when I'm ready. Thanks

i habe been powering my appliances with ups for more than 19hrs a day. The ups is designed for short backup and also can stand long backup too. Who says ups dont have surge protector? most ups has surge protector, just look at the back where u plug in appliances u will see its written there.
People always complain about their inverter not lasting like it used to when it was bought brand new ,its because they want to power everything in their home with it and at the end of the day they say the battery has gone bad. If u have a good refridgerator, u wont need to connect it to the inverter, atleast nepa dosent take away ur light for ever, get a good stabilizer for ur fridge or buy a small fridge that is also a freezer, its sold at lawanson, the fridge freezer is a small freezer. In one to two hours u freezer don block and it take some two day for the ice to melt,its sold at lawason for about 15k-20k tokumbn. So u dont need to always overload ur inverter.
All ur light bulb has to be changed to 15watts energy saving bulb or u construct one that the inverter can only power, i am telling nairalanders now all u need to do is dont overload,no fridge,no boiling ring,no pumping machine, no electric iron etc,
i am telling now ur battery should last 2yrs or more. Afterall nepa no fit carry light forever na

What you said might be true
But the fan thing is necessary to keep the system cool
For security reasons not to burn the internal component of your ups and also to prevent fire out burn.
I've never seen an inverter that doesn't have internal cooling fan
Even the 20amp charger u r using has a fan inside
I deal on inverters so I can tell u that
There are transformers and hot transistors in those devices that needs cooling if loaded and used for long period of time.
U can also make more enquiries online about using ups as inverter they also advised in the same issue

I was meant to understand that you need 3 things.
1. UPS (without battery)
2. Smart charger &
3. External Battery
you will connect the battery taminals to the UPS and the smart charger at once and plug both UPS and smart charger to electricity (NEPA)
How do you integrate the smart charger into this system?
Answer: ur smart charger connected to the battery terminal + and - same as u connect from ups to battery

(Pardon me for asking this silly question, its for clarification purposes)

@ceejay80s

Bosc:
From your explanation, I was meant to understand that you need 3 things.
1. UPS (without battery)
2. Smart charger &
3. External Battery
But my confusion is how to connect this 3 things together to achieve a purpose.
Is it that you will connect the battery taminals to the UPS and the smart charger at once and plug both UPS and smart charger to electricity (NEPA) or you will connect the battery only to the smart charger to charge when there is NEPA light, and (disconnect from the smart charger when there is power failure or when NEPA takes the light) connect the battery to the UPS to convert the battery power to AC for your appliances to use? How do you integrate the smart charger into this system?

very true, but that cant be a problem, my mini audio amplifyer keeps over heating and always burns the sound ic, all i did was go to oshodi and bought a 12v small fan ,connected it to one big capacitor inside, i glued the small fan insid the amplifyer and covered ane screwed it. If i put on the audio amplifyer ane the fan start spinning and cooling the ic and transformer, u can do same if feel ur ups will overheat, just go to oshodi, get a sizable fan that will sit inside ur ups comfortably, conect the fan to the big capacitor and face the fan directly at the ups transformer , if u cant do it, look for any electrician in oshodi market, dem plenty, dem no go charge u pass 200naira unless dem see say u be novice, buy the fan ur self first

ceejay80s:

u are not asking a silly question. We all are learning here, even me that started this thread have have learnt a thing or two here.
I have edited ur post when quoting . Read it, thats the answer

D set up is like charging ur fone with a desktop charger.Connect d smart charger's terminals to d ba3,link out d ups terminals to d ba3 too.I suggest u get an extension socket to b plugged at d back of d ups.Connect d charger to NEPA but d issue is how to know wen d ba3 is fully charged unless d smart charger is smart enough to possess ba3 full indicator,if not please get a mini volt meter sold at 400 naira to read d ba3's voltage section by turning d nob to left at 20v.During charging check at intervals till it full charge at 15V.Howeve,make sure u don't use d ba3 till death.Discharge it up to a safe level say 10.5V or 11V,den ccharge again.Since there is an external charger already I think u don't need to plug d ups to NEPA.DONT OVER LOAD D BA3 WITH PLENTY APPLIANCES.Now u can plug ur TV etc to d extension socket.

Yes u can integrate solar panels to it, but that means getting a solar charge controller to convert the solar energy to DC current to power ur inverter charging system. There are companies on konga that offer the full package, I can't give u a price range as u might need to research to find out what suits ur pocket and what brand appeals to you.

Personally I don't believe in brand names, though I know some are better than others but it all depends on how well u manage ur setup.

If u're looking at cheap then mercury and famicare can do it for u, while if u have some cash to spare luminous, Icellpower and the famicare 2.5kva inverter with built-in solar charge controller is cool.

For batteries mercury, luminous, sukam, ritar, quanta, sinergy and leoch are all good brands, but a smart charger added to the system will go a long way. But like I said it all depends on ur finances.

What about car battery bro ?
I know someone who use car battery with ups , He said he took the ups to technician and they change the transformer inside to higher one so it will charge fast , He charge the battery directly with the ups and it charge fast ...

What do you think OP, because the car battery can work with many appliances

dollarnaira:
Ceejay please is there a higher capacity charger for 100amp n 200amp deep cycle ba3s?If yes
please how much plus fone no of seller/address.Tanx sir

Bros u won build bomb? Lol, each of those UPS are meant to work independently, connecting a series of UPS together to achieve a higher capacity doesn't sound tidy, am not saying it's impossible oh. But if u're looking at using the UPS setup, why not build separate power ports to handle different parts of ur house alternatively u could just get an inverter with ur rated capacity to do the job eg 2kva, 2.5kva or 3kva, u can get a mercury 2.4kva for about 23k.

But let's be mindful and rmber what ceejay80s said that u don't need to overload ur setup, the fact that you now have ur own power source doesn't mean u have to overload it, cos that more u put on it the less ur battery life; and for optimal efficiency u must never put a load that's more than half the capacity of ur setup eg 1kva always put loads of 500watts and below for best performance, I'm not saying you can't go more but for best performance.

bishop4life:




You have a point. But mind you that most appliance makers put all that into consideration. As long as you don't overload your ups the components won't over heat and also won't get burnt. It's just like some local djs using fan to cool their amps, but most gud djs go for good power amps and so don't need the fan. So before you go on your project run a check on your intended power consumption and get the right appliance for the job. You won't have reason to complain later.

Cjsmack:
Pls Ceejay what's the output waveform of your 650va ups?

thuao:
can those baterries be repaired.
A friend was given I think 200ah battery n dumped it at home without using it for like a year now, is there anyway to repair it n make it work. he says its an inverter battery that he was asked to buy an inverter n use with it.
Can the battery be useful for me, can I repair it or thats the end.

vansledge:
OP pls answer this question... thanks

kolomax:
Guys we can import this thing together then it will save us some cash

i am in love with ur explanation
