post seem clearly made to hype someone, more like a compelled post. mentioning 12v battery, showing us pics of 24v inverter, no pics of the said battery.

Lollll.... abi sem won tell us say d batteey de in series?

Ignorance!

u see why i said it is a sponsored post. . even if he used 2 battery in series. the person being hyped isn't the right person to post a rebuttal.

APPRECIATION POST
Most especially I’d like to deeply thank @ for his guidance, hours of answering questions and even sharing his contacts and providing a transparent process despite not even being the one to assemble or install the system. You are a true reflection of what this space is about and I definitely will be referring my connections to you.

Again, thank you @! 🙏🏾🙏🏾

This bros just dey play on people's intelligence here sha.... if it is 100Ah series together, then what is 12v doing in the statement? I expected to see 24v 100Ah battery, isn't it?

Leave Dat guy... the end result of lifepo4 batteries in series with another has never been a gud one.

the thing is, the hypeman should have been the right person to post a rebuttal, not him . they just de bobo us for this thread sha

Genuine question, what is the end result?
Many assembling company doing 12v lfp now write in their spec sheet that the batteries can take up to 4s 4p.

The first picture is my batched and matched Eve 105 grade A cells.
The second picture is a normal 105ah Eve grade B cells.
From the picture, they all look alike and one may not really see the difference between the two until you subject them to C rate test and observe the working voltage range/cells behavior, especially at the upper knees during charging and the lower knees during discharge.
Again, the company gave 5 years warranty for the grade A and 3 years warranty for the grade B.

Grade A came with the manufacturer test reports and grade B does not have manufacturer test reports.
I will drop more findings/results as I'm working on them.

oga 12v system n ur inv de show 24v?

Go figure…or better still read again or check my post history here

Lol you really have a problem. Hype someone? To what end? Are you that unhappy? I’m not obligated to show zip. If you need more information, ask nicely, not make silly comments like that. As said, it was an appreciation post…interprete as u deem fit.

dollarnaira:
Point of correction, 100a 12v LFP is not "smaller" that is what powers my whole house bro. Everyone is in the middle.

Yes o. Running two in series for 24v and it’s holding up pretty good. Not a lot of information on the batteries for now but for the price point, I was willing to take a chance.

Honest question though, Why the client preference for tubular instead of lithium?

For our learning; the price difference between a grade A and grade B 125ah Eve cells is just $4. I believe this price difference will be similar for higher spec-ed cells.

What then could be the motivation in going for Grade B or A aside from price, which is nearly negligible

1. Quality
2. Durability
3. Rest of mind (You can comfortably power heavy loads withing the datasheet C rate specification without thinking about the cells deviation)

Thanks for the response, but i am not sure you understood my question.

I asked: if the price difference between Grade A and Grade B is neglible, why then would anyone choose Grade B over Grade A?

Also, how would you define "heavy loads"? Give us an idea of the Watts rating that define heavy loads. And do you imply that if one doesn't regularly power such heavy loads, he can get away with Grade B?

I am asking all these questions because of the dust these arguments of Grade A and B has raised recently

Second hand value obviously

Boss, the price difference between Grade A and Grade B is negligible with 20usd different for 280ah? I will like to know your purchase source for Grade A.
Some Grade A cells have 0.5C/0.5C charge and discharge rate while some have 1C/1C charge and discharge rate.
Putting either 0.5C loads on the cell with the 0.5C datasheet specification and Putting 1C loads on the cell with 1C datasheet specification is what I mean by HEAVY loads.
About 90% of grade B cell users put a max load of 0.3C on their cells.

Well, we may have our different values, but for a 280ah coupled/finished battery that will sell for 900k upward, I doubt $20 (32k) is enough reason to ditch Grade A for Grade B. I referred to Eve cells in my previous post and I buy from where all of us buys.

For the highlighted post; while I understand the concept of C rate battery charge and discharge, I wish you communicated in simpler terms. Remember we are all learning here and lot of less savvy people are here

Very clean setup as always my man.

My only grouse is I never like seeing tubular batteries directly below any equipment as the gases emitted by the batteries are pretty corrosive and will corrode whatever metal it comes in contact with over time.

I like SRNE devices, they are what they say they are! Good job.

Obnoxious2001:

Lol. For bbatteries that will die in less than 3 years. That second hand value may not be enough to buy 3 of that battery when it does die.

Just did another one today ! Working perfectly well

Good business I must say.


16 550 watts Jinko panels
10kw pylontech lithium battery
5kw Growatt hybrid inverter

Having used the pylontech battery for a while now, could you please share your general experience in the following areas?

1. Performance compared with lithium phosphate battery
2. Cost effectiveness of pylontech battery compared with lithium phosphate battery, putting energy storage (kWh) into consideration. That's 15 cells for pylontech Vs 16 cells for prismatic.

I'm asking to get practical/reliable information from your usage and this will enable me to give a customer who wants to buy it a sincere information/advice.
Pylontech battery nominal voltage is 48v while lithium phosphate battery nominal voltage is 51.2v.
How compatible is pylontech (mainly of voltage) with the connected equipment like inverter?
What is the major difference between pylontech US series and UP series?
Thanks

Looks like you guys simply have issues with Dam5reey1 because I don't understand why you guys are exposing yourself like this. The owner of the system said he went with "smaller 12v batteries". Did he say he bought only one battery? He even said batteries, not battery, why are you surprised that his "batteries" added up to 24v? And as it has been pointed out to you, some LifePO4 can be connected in series.

This is the point I think you should just leave well alone. If you have other issues with Dam5reey1, let us know, but on this case you are all out of point.

The client enjoyed his set for about 2 months and requested an upgrade!
We sourced the product with the client while choosing low-cost and efficient products, from Panels to inverters and batteries in a transparent manner. Installation was carried out, and the client did the load test, showing that he can now power all his 2 regular 1HP Hisense ACs, a Refrigerator, and a Pumping Machine without waiting for the Grid. Video coming soon on my YouTube channel.

5 X 570W High-efficiency panels. (780K)
6.2KW inverter (450K)
5KWH (1.25M)
The total package is under 3M Naira.

you want to know his purchase source.....lol
