are you saying i can get a 100ah battery for 30k ish?

He is talking of car battery not the deep cycle battery. it ain't advisable to use car battery. But u can get China 100ah for 40k

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

leagoo kicaa would have been great. but check the tecno wx3pro (wx3p). its 23-25k at retail shops.

Topmaike007:
I want to setup my own..pls can you give me the cost/amount that it will cost me

100ah battery 50k
2000watts China inverter with charger 23k
That's roughly what u need

.

deic9:
I will like to know the product you can recommend for inverter and batteries.
These are the stuffs I want to work with....thanks.

1 unit of 2.5kv inverter
4units of solar panel
2units of 200A battery

Well, it depends on ur budget but I have basically operated on China stuff and it appears to serve me.
It appears u want a fairly large system. soooo...

For inverter, even cheap Chinese inverters do reasonably well with no issues. Though I advice u go for pure sinewave inverters. A rule of thumb is to go for products made by those that have spent decades in production. U can thus go for Indian stuff like luminous, sukam or mercury and bluegate. There are countless products but most will work fine. some claim US products are great ( that, I can't say) but of coz, expensive.

Solar panels.
I don't know why u need 4 units and what wattage. I use Chinese product which is of coz cheaper. Canadian and German products are believed to have better efficiency but honestly, solar panels shld be the least things I would wanna care abt. Whatever u are going for, make sure is Monocrystalline.

Battery.
I am just an end user so a honest solar products dealer will best tell u best products. From my experience with car batteries though, big names ain't really great performance. The US trojan batteries have quite great reviews. Ritar too. They're expensive though. I won't advice u to go for China batteries except if u are on a tight budget. Check for german, or Korean products. Or better still, go with the Indians - sukam, luminous and co. Also, go to a correct dealer coz naija guys do sell recycled batteries as new once. Do ur due diligence coz battery is the main thing in any solar power system.

Thank you uncle Don for all these detailed explanations, I do really appreciate sir!


Can I get an inverte that will power just my laptop for 6 - 12 hours everyday for seven days?


Someone suggested I should get a battery used by all these heavy duty vehicles that it will serve, please how feasible is that?

Most vehicle batteries are "starter batteries". they are only used to give a very high current within a little time; of coz sufficient enough to start the vehicle. They are not meant to be deeply discharged and so once the car starts, the battery recharges back to 100% waiting for the next time it will be needed to start the engine again. Soooo, forget the truck batteries. moreover, from experience, buying a used battery and getting a good one is sheer luck. I don't advice that.

If ur concern is just the laptop, u can get a 500watt China inverter for abt 10k or get a 1000watt inverter for 13k (u can get it on jumia or local solar stores) if possible, buy the one that comes with an inbuilt charger so that when there is NEPA light, u can charge ur battery. if u intend to use the battery for the said 7days without charging it in between, then u need at least 200ah battery which I said earlier will cost u at least 85k. So obviously, u are on a 100k budget. if however u are gonna get power in between to charge ur battery, and you are on a tight budget, then look for abt 50ah battery which may be below 30k. With this, ur entire budget may just be abt 40k.

Thank you uncle Don for this detailed explanation.



But, is there a way my request could be achieved? I really need your suggestions and advice.

well, u have to be quite clear on what u mean by 7days. Do u mean the laptop will be on 24/7 or what? if that is what u mean, then u must consider a solar system altogether. If ur laptop will take like 2.7a per hr, it means it will take up 62.4a in 24hrs. and 437a for 7days. u thus need abt 3 200ah battery, each of which cost btw 90-120k depending on product.

room089:
Uncle Don, can this procedure power my laptop for at least seven days without blinking?

I really need some to power just my laptop for now.

seriously? 7days on an 8k battery? well, the laptop takes up abt 40-50watts and 18-19v. By dividing 50wstt by 19v, u get a 2.6a consumption per hr st 100% efficiency. now 18ah battery divided by 2.6a is abt 7hrs. so u can only get 7hrs from an 18ah battery if u are to drain it from 100%-0%. obviously, u will get less hrs.

Honestly, this mtn thing is slavery. It's highly limiting and since many Nigerians are ignorant abt solar systems, they easily get fascinated by the stories of marketers of this power bank. Let's see....

1. 100watt mono panel = 25k (mtn Lumos is 80watt)
2. 30a charge controller = 13k (with 6k, u can get it from aliexpress or jumia overseas shipping. Buy 2 just incase. u know China now)
3. 100ah battery = 50k (+-5k-10k depending on type. Note that mtn Lumos is just arnd 26ah)
4. 2000watt inverter = 25k (this one will power ur led 32incher tv) ( u can also get a local inverter. most start at 25k for 1kva)
5. 10watt ac bulbs = 1k each (6pcs will be 6k)
6. Wires and miscellaneous = 5k

Total estimate = 124k. (note that this is an estimate and prices will vary slightly based on ur location and type of products u buy.)

with this set up,
ur battery will charge at 100watt/12v= 8a per hr. so for ur 100ah battery, u need 100/8= 12.5hrs of sunlight to take it from 0 to 100%. also note that efficiency ain't 100% so assume 70-80% efficiency of panels which means longer charging time. For practical purposes however, I don't expect u to use ur battery to 0%. I expect u shouldn't go below 50% usage to extend it's lifespan. more so, at 50%, the battery shld return to 100% in like 7-8hrs based on the above setup.

For load,
6 bulbs is 60watt
laptop is arnd 50watts
led TV is abt 150watts
decoder 15watts
DVD player 30watts
standing fan 50watts

I assume these things could be used simultaneously for most people. thus..
total = 355 watts (even a 1000watt inverter shld handle this.) also note that rated power of inverters are just max output. during actual usage, continuous supply is said to be half its capacity. eg, if ur need is 500watts, u need a 1000watt inverter.

now recall our 355watts power need?
355/12v =30amps.
since battery is 100ah, we can only get 3hrs power with the above setup.

If we remove the TV and by extension decoder and dvd, we have like abt 7hrs power supply. always remember that efficiency can't be 100%.
For me though, with a TV card, I can watch TV through my laptop so I need not power my TV. more so, just 2 led 5watt lights is all I need. I am planning to get a very portable fan as well. with this system, u will get x3 of what mtn system gives.

As someone said earlier, access to money to buy everything at once is the issue but I think paying mtn 4500 for 5yrs is even a bigger issue. That's slavery.

Alternative, get a used ups for 4k, get an 18ah battery for 8k, disconnect the ups battery and connect urs. with this, u can power ur laptop and charge ur phones cos the ups serves as inverter and battery charger. note that the ups don't charge fast.

Pls is this battery suited for use with inverter? thanks.

Plz is the recruitment still on?...cos someone said they are still collecting applications at SUBEB

Yes but from the info I have, they have placed the receipt of applications on hold until after the interview.

monerozi5590:
Donpata, i got shortlisted for interview in the ongoing Kaduna State Teachers Recruitment Exercise.

Please, what should i be expecting in the interview?

Nothing serious. Since it ain't secondary school, interview would simply be verification of certificates. In any case, just know the name of the Subeb chairman, subeb perm sec, education commissioner, full name of governor, qualities of a good teacher and the likes.

Rockyfancino:
@donpata

I just got sent this thread link after been told the story a long one ago. I didn't read it, but it good to see you're now married and accomplishing your goals. I'll like to discuss with you off this platform.

My email is on my signature. I ain't a counselor though.

monerozi5590:
....are you still teaching under the Kaduna State Government?

yeah! 37k now. lol

And Buhari will say nothing.

dungas30:
bro so many people in ur community are doing it no need of stressing urself for info its poppular. all u need to do is just to get someone to draft u a form that has all ur condition for given loan also take caution of the people u will give ur money upon fulfilment of ur requirement thats all. just relax at home while profit comes inn monthly an u expand ur business as time goes on

Who takes a loan at 10% monthly? That's like 120% annually. Even microfinance bank don't charge that high. plus, I know of someone who used 3m to give loan in his community. Na lose the guy lose cos many no gri pay

I think maize is 7k now. Buy some 40 bags and keep. By March, it may hit 10-12k. At 10k, That's like extra 3k per bag. That's like 120k gain. After selling by match, go for locust beans. Sells for like 12k but could hit 18k at peak demand period. I haven't done either but there are people close to me that do same.

Durhleepee:
Bro, are you married now? @Donpata

yes madame. and so far, so good. bless God.

go for infinix hot 4 or hot 5. EOD.

Check the leagoo kiicaa power on Jumia. Its 20k

Only a dummy will believe this crap. Everyone wants popularity at all cost. News is too fake; wonder what it's doing on FP.

Africa - Where politicians are gods. Behind the scene, those women might have rained insults on Wike. After all that..... Hunger still remains but wetin concern me...

No true Christian will ever ask such question. If she is contemplating that, she should recheck her believe and establish that she is truly saved. The bible is very clear on that. That could take her away from Christ.

Look at Solomon, God gave him wisdom and when he became drunk with it, he went to seek wives out of Israel. You know how that took his heart away from God. Need I mention Samson and Delilah? At first, Samson felt love but still held on to his God. Later nnko? He had to give in and that led to his destruction. I also almost married a Hausa Muslim lady. I felt I was ready to fight for the love. Now, I am well rooted in Christ and I know that it would have been a very costly mistake if I had gone ahead.

Now, away from spiritual matters, in the north, any Muslim that is not Hausa is considered a half cast. If her husband eventually marries a 2nd wife who is Hausa-Muslim, the 2nd wife will be held in high esteem over her; her subsequent conversion to islam notwithstanding.

Forget all the sweet talk he tells her abt allowing her to do her religion and not marrying a 2nd wife. Later, that wil surely change.
LET HER CHECK HER STANDING IN CHRIST LET'S SEE WHETHER SHE WILL STILL ASK THAT QUESTION.

It depends. The 10yr old gap ain't the issue but ur current ages. Imagine a guy of 33 dating a girl of 23. There won't be much issue cos the lady will most likely be matured in mind and character. But urs is shifted backward. A 17yr old girl will have some childish attitude no matter how mature she acts. That said, I think u have to weigh her maturity level. If she acts maturely, I think u are good to go; you will however teach/coach her a in some areas. U must also be patient since u know her level. And finally, what is ur motive of going in2 a relationship with her? Cos at 17, she shld be a jambite. If u got nothing really serious; I mean like marriage in d next 3 to 5 yrs, free her joor.

LorDBolton:
You seem overconfident ...

Yes I am. Though not in my ability but through the strength of Christ which so powerfully works in me. I know I have to double up my game. I know it won't be easy. But I also know that in d next six months, my monthly income shall be greater than what I have now. How? I can't say but I believe and will act accordingly. Sooooo.... I can't wait till that time to do the needful. I must start somewhere.

WeNoGoDie:
Please how long does it take to charge from 0 to 100?. I need an honest answer cos I want to order for one. Thanks

Mine takes 3hrs 30mins. Phone is most times on 3g. When off, it charges faster.

PrecisionFx:
Did he also use 35k per month to buy 2 plots of land?

U guys should stop being stupid in broad daylight.

OK. For 6 months I received no pay when I started working in 2015. I was paid in the 7th month (Nov). 30k at that time. 30k by 7 is 210k. I got the 2 plots from a friend at 150k each. Paid 150k and the following yr did "contribution" of 15k with 10 people. I took mine 1st (january 2016) so I used it to pay for the 2nd land. Need more explanation Thomas? Lol

PrecisionFx:
that does not have any connection with planning, it's just a baseless trashy story.

He might be earning 35k as salary, but salary is not same as income. From all that he listed, it's obvious 35k can't do all those shit. Even ordinary N200 morning/N200 night food (assuming they feed twice a day) is already 400 +400 = 800.
800 × 30 days = 24,000.

rent and electricity = 6000 + 3000 = 9000.

35k has already finished.

So who will pay for every other monthly expenses.



Trashy article.

Let me help ur unbelieve. When I am low financially, I stay in my rented apartment close to my workplace. My work place is 30km from Kaduna town. Do u know how much I pay in that outskirt apartment? N500 per month. That's 6k per yr. Lol. Others pay N400 sef but mine is standard room. I feel The room is larger than the one u live in now sef. I have the external bathroom to myself cos the landlord and his wife have everything insuite their flat. Need I go further? I dont think so
