Good one Bobo65 and Frinx, from the look of things here, most deal hunters are greedy and selfish as they are only interested in getting vouch and selling their products. This is one of the major reasons Nigeria is not growing collectively, i dont care attitude/e no concern me. Same thing played out on Dallas thread, the regular buyers wouldnt fault the picker and talk sense into her, why? they want her to still be picking for them, we go still revise the matter another day.

Dragnet has long abandoned us here because we couldnt adhere to some things that were postulated, thats why he never commented on any issue/scam/deals gone bad again, baba don leave us to our fate. This issue of scam is something that should be condemned by all those who make use of this thread but reverse is the case. Going forward, i humbly suggest that

i. Every TLC deal should have the name of picker.
ii. If you doubt the TLC deal, confirm from the picker, request that ownership be transferred from the deal hunter to you before shipping.
iii. When requesting for an AIN deal, dont ask people to message you on whatsapp, just ask them to quote you then you reach out to them.
iv. For AIN deal, if seller is not in your location and you dont really trust the seller, kindly make use of an escrow. It is better to lose 500 naira or 1k that would be charged by an escrow than to lose 100k.
v. Everyone should save as many contacts as they can so that when someone claims to be another person, you can easily detect because you have the original number saved.

NB: I support Bobo's submission that the thread should be locked temporarily for 3 days as it was done when we had lot of spams on picker's thread. We should all discuss way forward/modalities on the resolution thread.

dominique:
I do understand how it works to an extent and I am also aware that both buyer and seller are exposed to scam. The farther the distance, the more the likelihood of scam to occur. It's safer you deal with someone in a similar physical location especially if you're not a regular trader

dominique:
Absolutely no evidence of scam here but rules 2, 8 and 10 were blatantly violated.

Avoid interstate deals to prevent stories that touch.

tchijioke:
Warm greetings to all the gurus that's giving life to this thread...
Pls I need your input to get the best possible setup with the available items:
1. 40amps mppt charge controller. Find detailed spec in pix attached
2. 6pcs 200watts solar Panels. Find detailed spec in pix attached.
Spec: Vpm =36.21v, Ipm=5.11amp
3. 12v battery bank already installed

QST: what would be the best panel connection/arrangement for optimal performance.
Thanks in advance for your responses.

tchijioke:
@Penuelseun thanks for your prompt response.
I have 3pcs of 12v 200amps battery.
I know a 24v system would do me a lot of good... But the challenge at the moment is getting a 24v inverter to replace the existing 12v...not yet ready for the expense. I just bought the panels and need some financial break before tackling the inverter upgrade head-on.
Once again thanks, I sincerely appreciate your contribution.

ojeysky:
Bros please can you tell me which of the options in the URL would match the attached picture

SolnergyPower:
Sir, the installation I am currently monitoring is on a two-storey building and needs a sky-fold er to access, so I am not planning to go there again soon until a major upgrade.

BTW, how did you arrive at 35A @80%eff?

earthrealm:
therein lies your problem, you are treating your mppt as a pwm, that is why your harvest is poor. i suggest you run 2s2p, ie hook up 2 panels in series. then parallel the 2 strings in series.
ie you would have 2 strings each made up of 2 strings in parallel, which you then parallel, thus ur CC wud be seeing 24v to 38v, thus enough head room for your CC to truly shine, as thats the sweet spot for it. efficiency upto 90% or so.
another option would be to string all 4 panels in series, efficiency of this setup is about 82% or so, what is the Vmax of your CC?, cos that is the determinant of if you can use this option or not.

@dragnet. , His subsquent remarks, shows he knows its mppt

Penuelseun:
No issues, been using it for more than 3 years. I use a bluegate ups by the way, I use it to power my 40" led tv, ceiling fan, home theater, decoder at a go and it powers them well.

Topmost11:
Thanks all. You have all spoken from your various wealth of experience. A difference of opinion is what facilitate learning. Don't let us have a dogmatic opinion; it doesn't help development. I have read all but have not digested.
Someone should pls review the conflicting opinions and find a common ground which you can all still review. If possible and the means available, experiment on the postulations and give your findings. Then we can all update our knowledge. The Einsteins of this world made name by challenging the stats quo.
I got here by challenging myself daily. The person that introduced me to inverter technology is now my neighbor. Isnt it funny that he still burn fuel via generator daily while my generator has been idle for some time now yet I have light 24/7. He recently got a sunking 60 for 34K while i built something slightly bigger for half the price for my mum, with your help via your answers. That is the power of an open mind.
Pls let's criticize constructively.

My 4×150watts panels are currently wired in parallel to a powmr mppt cc and still using the 12v inverter. The yield seem lower than when I was using pwn cc. That was why i contemplated series wiring. But I guess that is due to the incessant rains. If rain is not the culprit, I shall revert to pwm cc for the time being while I brainstorm on what next.



"you should try and stick to system voltage, ie 12v panel, 12v CC, 12V INVERTER
MPPT, YOU ONLY LIMITING FACTOR IS CC max input voltage"

The above is my understanding before all this differences in opinion.

PS: Sorry for my long essay

earthrealm:
ok, maybe you should hv added personal opinion to the advice, you gave the fellow.
pwm cc will waste any excess energy..if you feed it a higher voltage than specified, mppt will not, but would rather convert the excess voltage to current. if they are all the same, why do u think the mppt is more expensive?

gustav25:
Anyway , I'm done here ...The message is clear

gustav25:
lol... You don't know what's going on

ojeysky:
There was a time a discussion about how to connect batteries in series/parallel but can't seem to find that discussion again.
Please I have 4 X 150AH 12v AGM batteries and like to know how best to connect them together for a 24v setup?

earthrealm:
that has an inherent problem, and would need expert supervision to make sure damage doesnt occur.

am thinking along the lines of overcharging the batts..., assuming his pumping machine is 1.5hp..ie 1200w approx, he would need panels of that wattage to scale by, factoring in losses and all. say he has a 1500w array, at 24v, thats about 55amps or so...though average wud be 30a to 45amps, i averaged same when i had 1500w on a 24v inverter. let him steer clear of flooded batts, as they dont like such high currents, as i dont think it would be possible for him to always be available, monitoring the harvest, so as to go switch on his heavy loads, when harvest is high...

earthrealm:
your plan is doomed from the start, make effort to read previous pages, this issue has been discussed a thousand times.

max load u shud put on a 12v 200ah battery is c/20 wch is 10amps which is equal to 120w, since u hv 2 of them, then its 240w...u may not do serious harm to the bank if u intermittently draw x2 of this say 480w for short periods ie c/10, but anything higher than this...spells premature death for the battery.

google well, to gain more knowledge about what you are about to enter into

Negro1:
The model number is UPSEB1400

I've attached the picture requested

Sorry for the late response, I've veen away from home for a few days.

garbamaza:
Good morning everyone,
I need an urgent clarification, can I use 16mm² aluminum cable from my 2kwp solar panels to charge controller with distance of about 18.5m.
Thank you for your possible urgent response.

Abigai:
Pls can this battery (2v/1000ah) give 12v or 24v?...

Negro1:
Available

Tenshades:
With due respect, this topic is about "how playing Ludo is HARAM"

I came in and opposed it cos if the motive behind the ludo isn't for gambling, I don't see why we should innovate it to be gambling. And I said if the Quran doesn't paint something as Haram, then it's not Haram.

But you claimed LUDO is HARAM including playing it for fun, isn't it? Referencing to your Hadith/Shariah claim and I want you to tell the world where Allah urge us to use Hadith to supplement Quran since you said Allah's messages in the Quran are insufficient. But here u are dodging and asking questions about solat according to Quran.

Tenshades:
Refer back to the Qur'an verses I posted for you to ponder on... That's my proof of Quran being SUFFICIENT.

Tenshades:
I have told you to tell us... Please, I'm begging.

Tenshades:
Accepted. I'm running in circles.
Now can you kindly let us know the answer so that we can get facts right?

Tenshades:
I want to learn now. And I am so eager to learn from you but you are holding back the truth you know from us. I told you I don't know so that you can let the world know. The world is watching and waiting for your answer.

We are waiting.

Tenshades:
Your question is about how Quran and Hadith reached us and I told you I don't know so that you wey know can Enlighten us and tell us what we don't know.

Tenshades:
LOL... Is this what you want to divert the talk to now?

Tenshades:
Things don't work that way, you don't answer my questions and you want me to answer yours? Is that how you make yourself clear to people?

Tenshades:
Sir, I have told you in my response above that I don't know and we will be glad if you could tell us here. Please go back to my responses above and read my answer.

Tenshades:
I once listed few Qur'anic verses for you to re-visit and ponder on them.

Here is just one of them.

Quran 6:114 Shall I seek other than God as a lawmaker when it is He who has brought down to you the Book fully detailed ?

Take note of "God as a lawmaker" and "Book fully detailed"

Since your claim that Qur'an isn't sufficient as opposed to that verse as stated that QURAN is "fully detailed" and God is the only lawmaker for ultimate guidance, I won't have to go further at this juncture in argument.

Salam aleykum.

Tenshades:
"QURAN IS INSUFFICIENT" Then Allah forgot to send down some messages isn't it?
Congratulations.
I wish you well on your Hadith and Sharia usage.

Tenshades:
Oga, if we are to talk about how Quran and your "Hadith" came to existence, we will have to open another thread.

And lemme say I don't know so that you can tell us here how they came to existence so that justice could be done to this argument.

Moreover, you not answering my question doesn't make your stance clear.. You are only making it look blurred the more. We are not in agreement because Allah doesn't urge Muslims to use "Hadith" to supplement Quran.

I don't even get your point self.

In a nutshell, are you saying Allah forgot to tell us everything we need to know and follow in the Quran thereby directing us to use "Hadith" and "Sharia" written by mere mortals?
