I want to install a setup for my people at home, my installer gave me a quotation of 1.6m for the following:

2.5kva inverter
2 * 200 AH tubular batteries
4 * 300w panels.


I obviously won't be getting the tubular batteries with the knowledge i got here, i just want to know if there is a Lithium equivalent so I can purchase these parts myself?

Moreso, with a budget of 1.2m - 1.3m, will i have this?


Our load audit:

3 ceiling fans (might replace with energy-saving standing fans)
1 LED TV
5 bulbs

All odds during an urgent installation:
Battery 12v 314ah lifepo4
PowMr cc 100k
3kva Satchet inverter 100k
Cable 6mm² 10yrd 40k
2 555 Jinkos 240k
Balancer 18k


Loads: 65inch tv, freezer, 2 fans, 6 bulbs, 1 0.5h submersible for 15mins water don full.

Add am up.@Darey00
Na who get sense they use solar. Do not follow trends. Do what works. Good energy goes beyond fine boxes.

HeavenlyBang:
Cable cost here is really just battery to inverter, which is usually like 3 yards at most.

Regular 6mm cable from PV to inverter is unchanged, same as cable for inverter to outlet.

Where do you buy cables from

I appreciate this

Abeg who knows where I can get the Lithium battery recommended.

I have seen some panels on foani store as recommended by @HeavenlyBang and everyone else.. then the CWorth also inverter I don't know where to get that from.

This thread has been an eye opener.. I've learnt a lot in my short stay here

Haykay2001:
Hv not been following your question.. Let me ehter from here... What are their load like...

From what the above perosn gave you, its good but lately all this 12v hybrid inverter are noting to write home abt..

Just hv that at the back of your mind.. If only you can get the sern 12v system... Apart from that, other are noting to write home abt... Sako, welion, sms, and those at that level...

If your load is max fan, with your budget, will advice you go for serchet inverter.. 24v own and powmr cc the 2 are under ₦200k maybe ₦190k something the cworth battery the oga bise said 12200 own at ₦555k.. Then jinko 555w x2 ₦300k...wire and the rest you should be fine with 1. Something million..

Thanks for this boss...

If you have leads on where I can get the battery and Inverter I would appreciate.

KaylaDeriy:
Thanks for the interest in Deriy, let me answer them all.

1, Regarding the production of the battery cell is 2021, please add my WhatsApp, +190 68617017, so that I can check the batch of your product. Because sometimes, the software for scanning is made by human beings, and sometimes it will recognize wrongly, because some software is specially used to scan EVE and CATL kind of batteries.

2, Regarding the BMS's being set to charge at 40amp,I think all my clients in my telegram group know that I had shared a picture of the recommended parameters for BMS, which is as shown in the posted picture and we recommend 280amp charging.

1.
This shouldn't apply to all 16 cells in the Deriy Battery because I scanned all of them. You see there's a reason battery sellers like you hide QR code of cells, it's to hide the origin of the battery. If the battery is new like you claim, you should be proud that the customer would be able to scan the QR code & verify that it's brand new like you claim. It helps your marketing, but you use fake QR code to hide the battery origin. Looking at the QR code image I posted, you will see it's lacking battery capacity & other info. So its very bad you're selling an unknown battery & passing it off as new. If you're in the market to buy a lifepo4 battery today, would you buy one that's made in 2021?
Selling used grade B or C batteries won't be difficult, just be honest about it. People will be happy to buy them once the price is right. Besides these are just fake codes...

2.
The image you posted is in Chinese, but see the English version in my image. Are you seriously trying to pass off battery capacity as the charging amps? As you can see in the image 280amps is the battery capacity... Meanwhile in your manual you strongly recommend charging the battery at not more than 0.3c, why? If you now recommend charging at 1c, is it not better you reflect that on the manual. Manual is attached.
Is there a specific problem with the cells that they can't take 1c charging? Pls you need to address this here so that people should be aware before making the purchase decision. This is very important because one of the advantages of lifepo4 chemistry over others is fast charging, if people can't take advantage of that with Deriy battery, then they can look elsewhere.

It's nice that you're no longer using welded cells because they're not DIY friendly. Most DIYers here would agree that bolted busbars are better, whether flexible or not since the battery will always be stationery.

GloryJoyeux:
Disadvantages:
1. Welded cells (this is terrible)
2. 2021 manufacturers date ( so many red flags, even if they are grade A, where they stored in perfect condition for 4 years!) this is called Long term storage surplus or new old stock or Grade A- /B
3. You will only get you 280ah when u discharge to 2.5v. At 48v you will have less that 280ah

You're right on no. 3, I've not done the capacity test but looking at the battery voltage at 50%, it's obvious full capacity will be around 46v or below. And to think they even claim the real capacity is 300amps This is not a good buy. It's not that Hithium cells are bad, I've tested new ones with verified QR code that pulled full capacity better than EVE. It's the dishonest seller Deriy, selling used cells as brand new

jonescosmos:
Hahahaha, Piracy world be like drug cartel world bro.

Please post a clear picture of your MC4, Terminal Junction and Sticker lets see if they passes quality control, if not and you bought it not long ago, return the PV asap.

Jinko has about three known plants, in Vietnam, Malaysia and China and all three has a unique sticker to differentiate their products. You sticker doesn't seem to fall in any of these plants mark of quality.

As for the MC4s, them dey sell am for market now ooo.

Please how about this sticker? Does it seem genuine?

jstemmanex:
Think I may be considering SAKO



It's cos of the load I want a 2.5kva. (washing machine, fridge and 1/2 horse power pumping machine)

Just go for a 24v system. At first you said tv , 3 fans and bulbs but now you are adding washing mashing, fridge and pumping machine. Do a proper energy audit and ask for a suggestion based off that. Else náà premium tears

Of cause for my own use as an engineer i run this.. And i know go to take care of it fine.. When to over use and when not to... And it works perfectly for all the above listed.. Including with all this blender as well... Aside pump sah.. Me never run am on pump..

And the 12v theory on powmr with 2 580 0r 555w jinko panels way una they always talk for here, abt hin volt me no understand oo.. Cause for the mini installation for my client, that what i run for them and it works perfectly fine.. In SERIES connection ooooo..

I greet you

Hi GloryJoyeux I know this is random and can be unnecessarily stressful for you, but please can you simulate, using you deye inverter, a case where it works without grid and without battery ie disconnecting the battery and grid supply. I want to be certain it would work without battery if there's no grid or generator to supplement pv before I buy.




Also I saw this image online. Does this mean that the size of wire connecting the panels to the inverter will be 2mm ? Is this correct ? I used to think it was 6mm until I saw this

Ahyjo:

Post terminal junction too. These guys in Alaba are becoming smart

Sometimes these manuals dey mistake. 12awg is 4mm², that 2.5 na error. 12awg is 4mm², 10awg is 6mm² (You can check online to see it). 6mm² is recommended here due to our temperature and also perhaps how are you sure the guage of wire you are buying is correct? So 6mm² is just safe to go with.

Okay bro
So full gauge 6mm² wire will work well without any disadvantages right ? And if I get full gauge 4mm² wire, it will be perfect ?

GloryJoyeux:
Hi,

It seems you do not understand what the ‘no battery’ means and how it works.

Are you trying to install an inverter with no grid and no battery, but want to use only pv to power your loads?

That is not what the no battery feature on deye inverter is for. The no battery feature works when grid is available, it then uses pv power to reduce grid usage and it can also sell excess power back to grid. In the absence of grid, the inverter will shut down even if there is pv.

https://powerforum.co.za/topic/20621-deye-8kw-inverter-without-a-battery-installed/

Now, regarding what you are trying to achieve, do you know that even if you buy an inverter that can work on pv only without grid and battery, it will still trip off when some appliances that have surge eg water dispenser, refrigerators, air conditioners, pumps etc are turned on.

You may wonder why, well this is because the surge is very fast and instant and mppt are slower in scanning the range for mpp to instantly provide that surge that is needed for such appliance (if grid was connected, it would have used the grid to supplement the surge).

Also when there is cloud cover, the production will be low and it will also trip off even for non-inductive loads.

I actually tested this extensively with an SMS 6.2kw inverter, I used it without grid and without battery connected, just pv. It will trip off when you want to power a refrigerator, pump etc because of the reasons I mentioned previously, it will also trip off when there is significant cloud cover (because there is no grid to fall back to)

So you are advised to stick with a no battery set up only if you have reliable grid supply and thus the solar panels will help to reduce the grid energy used when solar is available (i.e. less units used in daytime).

Thank you bro.
My intent is to power fans, bulbs and a TV pending when the battery arrives. Based on what you said, this wont be possible with the deye if there's no Nepa or generator even though I intend to overpanel and monitor usage? And also, how many mm² wire did you use from pv to inverter

maklelemakukula:
Okay bro

'full guage' 4mm² will work well, as long as all your panels 'remain' in SERIES.

I want to buy the cable from techland, any chance they dont sell "full guage"

Building on Gloryjoyeux awesome reply to you (as usual), there is a video on youtube from a popular enthusiast I think you should watch where he reviews Hithium cells 280ah.

It's a long video but to summarise it he comes to the same conclusion as Gloryjoyeux as to the quality of Hithium cells (compared to Eve) and their "creative marketing".

But as usual, as I find with Youtube, the real pearls come from the comments section, and I am highlighting one from a particular guy about how the cells market works in China and I'll post it here as I believe it will be beneficial for all of us:

Andy, I have been importing these cells for a while now to South Africa, and have the following conclusion:

There are only 4-5 (real) manufacturers of prismatic LiFePO4 cells in China, they are:
EVE,
LiShen, (Lichen)
CATL ( China Aviation Lithium Battery Co ltd),
BYD
And then also Samsung/Panasonic/LG; but you will not find the prismatic cells easily.

These manufacturers generally sell to other large manufacturers mainly EV,s and larger commercial entities.

The cells that does not meet the cut in required standard/specification generally ends up for auction in China and multiple companies buy these cells up, weld studs on, re-wrap and re-qrcode these cells. The biggest issue is consistency of product but it is possible to buy 360-1600 of these cells from the re-sellers that came from the same manufacturer as well as same production batch.

If you buy smaller quantities (below 10 000 units) you will not be able to buy directly from the manufacturer in most cases.

One of the reasons for the new qr-code is because the original manufacturer insists this is done, EVE for example since February 2022 only allowed there cells (so called rejected cells) to be sold on if it had a "B" in the serial number.

P.s. there have recently entered a few more manufacturers in China like OptimumNano, Wanxiang A123, Guoxuan, WINA and JB Battery.

The cells that is sold like what you buy from Alibaba and AliExpress are never directly from manufacturers but more likely bought on auction, re-wraped, re-qrcode, via re-sellers.

They are from experience 87.4% of the time reasonable cells and will give rated capacity and give you many cycles 3600-6000( chemistry department not manufacturer)

The secret is the find a re-sellers that can consistently provide Quality cells. I have only been able to fined three of these

What is your battery size?
Note: You can never get 60a.
The highest you can get is true 35a with clamp meter. The display on PowMr is not that true.
Right now am pulling 30a on just one 555w Jinko. You need basic knowledge.....
