Oga, why u carry ds thing for head like afro dey reply every body nah. Must everybody use what you dey use for ya village? The illegal devise wey no fit power 32 inches lcd/plasma na im make I put for house abi? Walahi tiger generator better pass am.

This is not an entirely sincere review OP. It is more of a biased, bigoted review

pobeaf:

An average reader of this thread will expect you to mention any part of the review that is biased and bigoted but instead you are just spewing derogatory and rude remarks. Pls park well, your type is not needed here

pobeaf:

I had wanted to ignore you since you don't have anything good to say but when I discovered that you edited your comment to insult me... I think I need to tell you this...you can't just be insulting me because you have access to the internet. If you are not satisfied with my review, pls get out of here. It isn't by force you comment here

I think this is nice though but I have issue with the 60watt maximum power you get. That’s way below my needs, or should I say expectation. My neighbour uses it and he comes to my flat everytime I put on my Generator to charge his phone. I think he has an issue with the phone being compatible with the inverter socket. It charges his wife’s phone but doesn’t charge his.
also, he had to sell his LG Tv to get a 40watt chinko TV I never heard of in my life till he mentioned it. Other than these 2 issues, I think he is loving it.
I only have an issue myself, increase the Watt so it can connect to the whole house comfortably.
Also, if there are alternatives to this at 70-120k with higher watts, someone should kindly suggest. I believe the profit margin on monthly rental is what MTN is after. At 270/300k full cost, I want to believe mtn’s profit is around 150/200k per unit after full payment. But then again, it’s like giving you a loan, so won’t blame them much

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.

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.

donpata:


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.

room089:



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.

donpata:


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:



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?

donpata:


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.

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
