Hello, your battery cells might be weak ! I believe your ups isn't a pure sinewave , that is the major reason your fan coil degenerated in performance. Only a few people knows that most ups which ain't pure sinewave affects fan coils on the long run. shocked
If you must use a ups , go for the
-24v APC smart inverter which ranges from 20-25k.
-2 units of 100a agm batteries
-24v smart chargers or the affordable Emerson brands.
I have been using the APC for past 10yrs and its very durable & reliable . I only have few APC units at give away price. Cheer's

Please, can you throw more light on this pure sinewave characteristic and its significance to the mini/inverter set up

We learn daily ! Sorry for your loss. I didn't really get if battery was brand new in your explanation, I am also aware that there are some factors militating against "warranty" like overcharging , fire, physical damages etc.
It would have been more understanding if the seller explained to you a bit for good business relationship sake but nevertheless , contact me for a more lasting solution. Cheer's !

Thanks for your response, again. As it stands now, can you offer some tips with which i can manage this battery, pending when i resolve with the seller or buy a new one. i would appreciate.

Hello,
Pure sinewave is simply pure sinewave both in bigger or smaller applications ... Its synonymous to grid efficiency/output .. It comes with realtime surge capabilities.... It dosnt depend on chopper transformers unlike modified specs .... Sensitive appliances runs best with puresinewaves .
Its all depends on clients choice , budget, scale of preferences etc . I personally stopped using modified more than 12yrs ago as its negative side as listed below shows on the long run;
-it causes distortion -wave interference
-it weakens coils
-it isn't surge tolerant and MOSFETs tend to get weak and wear out fast
-its prone to repair and fail
-its inbuilt charger developes periodic fault
-it shocks and needs proper grounding most times
-it humms on some sensitive motor equipment
And so on ..

If you observed , there was an era in Lagos when the aluminum plated modified sinewave(new & used) dominated the entire market like "Opel omega" cars of those days but it no more under serious demand like before unless for unaware newbies. If I must go for a small set up, I would rather go for 12v 850va Indian pure sinewave brands , bluegate 1kva pending on the total watts of loads you need to power etc

I feel its just best for lighter use , marine use, camping et al .... Hope my lucid explanation helps smiley . Cheer's !

I don't forsee an average reseller changing a bulged-swollen battery as companies themselves rarely accept warranty on that as its physical damage due to equipment malfunction.. They ain't liable for that damage. Its best you save up , and count that as your "loss" . when you sense a battery isn't receiving charge , choking or battery takes much time than required to get filled up, pls it means there is a fault somewhere. Stop charge to avoid swelling, electrolyte leak or explosion !

How much then? the Projector would be used one hour a day for 5 days a week, so I just need recommendations on a setup that can last up to an hour.

from following this thread, getting a 40ah battery and a 12V inverter would do and can give me about 1hr 30mins, but then I may be wrong.

I don't think 200ah battery is necessary for projector application. Since ur budget is 50k, I think u should...

1. get a 50ah battery for abt 30k.
2. get a 1000 watts inverter for 13k.
3. get a 20a battery charger for 15k
Total 58k

or,
1. get a used ups for 5k
2. get a 50ah battery for 30k
3. get a 20a battery charger for 15k
Total 50k
Here, ur ups will serve as inverter. get a ups without its battery cos that will make it cheap.

or
1. Get a 50ah battery for 30k
2. get an 80watts panel for 15k
3. get a China charge controller for 5k
4. get a fairly used ups for 5k
Total 55k
Here, u can use solar to charge and also use ups to charge. of cos, ur ups will serve as inverter.

A load of 200w drawing from a 12 volts battery will pull abt 17a per hr. That is less than 50%draw of ur battery. Taking into consideration inefficiencies, bad as e go bad, u will only pull 60-70% energy from ur battery at the close of whatever u intend to do for 1hr-1:30hr. @sleekest

Nice point but he must add a contingency plan whilst going solar for miscellaneous cable,breaker fuse procurement costs etc .. So he needs to balance up his budget a bit instead tryna squeeze a square peg into a round hole ... When some clients come up with this brain cracking proposition , that's when you see most advicing they use sealed car batteries which ain't best for deep discharge purposes but a 100a brand new car smf battery will serve him at less than same 30k, whilst he opts in for solar as he can even get a fairly new 20a pwm charge controller from me and a brand new 80-120w solar panel at discounted prices !

Note: while the op plans for just 200w at less than 2 hrs run time, solar integration gives you a head room to run at longer hours without solely depending on grid - gen supply ceteris paribus !

Goodmorning Guys.

I am having issues with my setup. My setup consists of a 30A smart charger, UPS and 100ah battery, and it is less than 1month old.

No matter how long i charge it (even without using it and with the smart charger knob set to 120-160ah), it never seems to get filled up, and when i use it, it doesnt last me up to 4hours with my load of approximately 145w (laptop 70w, fan 65w

Also, for some very strange reasons, my standing fan (not rechargeable) doesnt work on the set up. the day i launched it, the fan worked perfectly, but an hour later, the intensity dropped. Now, it comes on but doesnt rotate. But when i plug it to normal electricity supply, it works perfectly.

What could be wrong?

My bros, I can confidently tell you that there was no water in your battery at all. The battery will never be full because there is no distilled water to hold the charges. Get water from an air conditioner, use it to fill the battery through the holes, charge it with your smart charger with the knob placed at approximately 80A. please leave the holes on the battery open while charging it because some of the distilled water will escape.
Charge the battey full and use it. I hope the heat generated by the battery while you were charging without water has not cause any leakage on the battery though.
Am telling you from experience because i had the same issue with one of my batteries last 2 years. The battery is still serving me till today.

He is talking abt efficiency. The thing is, with an 80 watt panel and a 12v battery, 80/12=6.7a. This meas at 100% efficiency, ur panel will send 6.7a to the battery per hr. So, if ur 100ah battery is at 0%, it will take over 20hrs of sunlight to get it to 100%. That is the limitation here. at an efficiency of 80%, the time will be longer.

However, it is not likely u will discharge ur battery that low. let's recall that ...
ur need is just 1hr usage with a 200watt load. soooo.... 200/12=16.7a. This means u will use only abt 17amps for an hour. bad as e go bad, for inefficiency issues, let's say u use 25amps for ur 1hr daily need.

Now, let's assume ur battery for whatever reason is at 90% an not 100%. at 90% (90amps) drawing 25amps would take the battery to 65amps.
Or better still, since u only drew out 25amps, replacing same 25amps using ur panel will take just abt 6hrs of sunlight when we consider inefficiencies. Soooo, for ur projector usage, my initial suggestion will work. with extra 3-4k u will get a 100watts panel. but its even better to get an mppt solar controller than can convert wasted voltage to more charging current. (actually, panels give out more than 12volts but ur 5k charge controller will step it down to 12v to charge ur battery. the extra 5-7volts is then wasted away. a mppt controller however helps to convert the "wasted" voltage to more charging current. as u may deduce, it will cause u extra bucks.)

Hello,
You remind me of experimental days when we cut open a sealed agm lead acid battery and apply distilled water or electrolyte for revival sake grin ! I believe the op uses a sealed battery and not flooded , I also read where the op said somtin about "swollen/bulged" battery . I don't really advice a DIY client to toy around acid - battery for safety sake as the chance of revival is highly infinitesimal !

https://www.youtube.com/watch?v=puMRpTOwnNM



This powerbank is a mini energy solution that is targeted at solving many any challenge we have daily like charging phones, powering TV and like you rightly requested now, it can power your bulbs


The maximum power it can supply is about 100 watt but out there there are power solutions to (inverter and batteries) that can supply as much as 1000 watt, I personally have a 2000 watt inverter installed at home too, many have up to 5000 watt inverter installed...... These are all beautiful installations and can do power many high energy consuming device


For example a 5000watt installation with 4 or 8 units of 200Ah batteries will conveniently power almost all your home appliances at once
But here is the 'challenge'..... One of those 200Ah batteries cost about 100k and for 4 or 8 units, you will be looking at 400k or 800k respectively for battery only..... Inverter on it own can cost in from between 100k to 500k for a 2000watt to 5000watt rated inverter....



If you intend to add solar that is another 250 to 500k expenses....
So my question is why spend so much when all your priority is just to get your home lighted or to watch TV when you like to ensure your subscription doesn't just waste away, or to power your energy saving fan or laptop......



Our mini energy solution can help you solve many of these needs above at a friendly price which can be far less if you only need it for light, or only to charge phone or only power Laptop..... Pls take note of the word *ONLY*
If you will need to it to do all of the above and even more then you may need to buy the upgraded Powerbank/Battery, inverter, Laptop connecting cable, charger....

It is not that MPS cannot power many or all these together but caution must be taken to ensure that the 100watt limit is not exceeded.


To give an insight on lighting, some 20 years ago incandescent bulb (those ones look like lantern light ��and get so hot) were the popular type of bulbs. The least of these incandescent bulb is about 60watt (and note: OUR MOBILE POWER SOLUTION PACK can only supply about 100watt-----that means it can only power one incandescent bulb�����‍♀)


But like many of us know, power is not cheap in some part of the world.... Some people pay special attention to how much power they consume so that power bills don't take away all their savings for summer holiday.... So there were more research into energy efficient devices and that lead to the invention of many lesser energy consuming device popularly referred to as energy savers



The popular energy savers in most people homes today are rated 25 to 20 watt and many has the big 40watt energy saver bulbs but research has even gone farther to give lower energy consuming bulb/device....


There are 5watt, 7watt, 12watt energy saver bulbs that are just as bright as the more popular ones but surprisingly or not so surprising �most electrical stores/shops don't stock them..... As e no dey move market ����


Another thing worthy of note is DC or AC convention.....

DC.... Direct Current
AC - Alternating current

Direct Current.... Which is mostly 12v like those of batteries, solar panels etcetera...... Virtually all electronic and computer hardware needs DC to function......manufacturer builds components that converts ac to dc into their device......for example most laptop are 19v device and it takes the adapter the rectify the 220v AC into the usable 19v for laptop..... Power is lost during this conversion. MPS has a 19v port for laptop and a 12v port for other DC device or an inverter to convert the stored charge to 220v that most of our electronics use.


The voltage and frequency of alternating current (AC) electricity used in homes varies from country to country throughout the world. Typically, either 110-volt AC (110V) e.g USA or 220-volt AC (220V) e.g Nigeria.... is used, 'usually connected from the grid into homes, or from power generating set etcetera
