obinna37:
the label have removed, the brand is sharp,voc is reading 40v, current is 6 and above,

Hun?
Label remove ke.
How did u get the above info then?

obinna37:
70k

Brand and spec pls
Pix too

Obnoxious2001:

Pure sine wave can be built and they are been built in Nigeria.

By the way if you are trying to cut cost, you can get an old UPS and convert it to an inverter system.


Start reading from page 1 of this thread every information is there.

As an individual builder locally?

obinna37:
I'm selling two together, Lagos

How much?

psucc:
The installer I met said he can't do with satchet inverter rather he will build the inverter to be sure of what he is supplying.
He also said he prefers the Canadian used panel to new ones.
Is this ok?

He cannot build a pure sine wave inverter.
Who are those condemning satchet Inverter?
There are several nice ones.

Juror:

SRNE

Thank you very much

ksmart027:

Thanks boss, finally, is there anything wrong with used panel? The boss above advised against it, so I want to know your take, thanks.

No crime using used panels if the price difference is very obvious.Brand new 425w jinko is around 135k, if a used 300w of any brand cost 30k it is fair. Fund is the culprit.

Getting dead laptop battery here my state is now a difficult task.

Did u check the state of charge of individual cells before the combination?

Fresh thread

Kiekie and carolyn19 I beg make una no post things here.

This thread is NOT for ADVERTS but strictly for diy experience under building safe lithium ion battery packs. Cylindrical LifePO4 diy also included.

officialfestus:
Soldering stage is next, I'll be getting the wires soon.
@penuelseun @dollarnaira

Fantastic!!!
This is roughly 80A 3s40p
Remember to build packs of the 40p and BALANCE CHARGE them o. Allow dem to rest for few days to check for voltage drop.

CAROLYN19:
Are you in need of a rugged, Effective Uninterrupted Power Supply (UPS), Vertiv UPS is what you need . You can Reach us on 08066332919. We have offices in Lagos and Abuja.

You and kiekie are the problem of this thread.

officialfestus:
12 volt 40Ah.
Due the increase in dollar, ordering the cell brackets was too expensive, so I had to make use of 3/4 PVC pipe.

@Officialfestus
This idea is brilliant.
Sincerely speaking this thread has lost its purpose. Am a diy lithium ion freak too.
May be we can open a new thread tagged:
DIY LITHIUM ION LIKE-MINDS
Kiekie don finish this place with yeye adverts.

I need a pwm with lithium settings or adjustable settings. Pls help with a brand or brandless...

48-Volts is sweeter.
of course both 24 and 48 volts system ain't cheap. in fact 48-volts system na for people wey get money.

meanwhile, I wasn't making suggestions, only responding to question asked in ways anyone not knowledgeable enough, could be able to make informed decisions without asking more questions.

The higher the input voltage, the more efficient the system would be, and also the less FATTer cables you would require.

True but a continuous load of less than 200w do not need 24v.

bassdow:


The higher the input voltage, the longer it would last on a charge.

in other words, 24volts 200AH inverter system would last longer than 12volts 200Ah inverter system; likewise, 48volts 200AH would last longer than both 12-volts and 24-volts 200Ah inverter systems.

in fact, if care isn't taken, a 24volts 150Ah inverter system might last longer than 12volts 200AH inverter system.

So the higer the input voltage, the more efficient the system would be, and the longer it would last on a charge.

24v is sweet but..
The truth:
Is 24v cheap?
Is it easy to maintain?

osayuwamwen:
I already have a 12v solar inverter of 1.5kva, I'm planning to change my submersible pump to a solar pump instead of upgrading my solar system to bigger size, buy a solar pump will be cheaper than upgrading my solar inverter system, my question is can my 12v 1.5kva inverter power a solar pump if maybe connected as AC to my setup

What is the hp?
Consider initial surge.

osayuwamwen:
Can i use a solar submersible pump on my 12v solar inverter system?

0.5hp will work on 3kva 12v

Justice629:


This is the typical example of the pros on the group who knows nothing about ESS but are quick to jump in on any topic with their naivety claiming to be professionals.

I am fully diy off grid on both my home and farm with a combine solar system of 14KW pv, 60KW ESS and 20KW inverting power, if with this setup you still think I have little knowledge about RES then you need a phycologist.
I had no choice but to get cells from Val due to the logistics delay and my immediate needs to start my RES journey. I made it know to him after receiving the cells that they weren't good cells and most were bloated.
I don't have any issues with Val because the quality of the cells were anticipated and I have been dealing with it ever since.

You have a big problem understanding English. If you like run 20millionKW na ur palava. Like I said above, you have huge problem understanding simple sentence in English. Read in between lines but slowly this time.

@bassdow
I gbadu your inputs here well well but as I no be keyboard warrior I say make I maintain for corner the look many of them do called solar pros here.
Little piece of advice- when you ready to go lithium no make mistake of buying from naija vendors because must times na worst grade cells them dey buy from China, my own experience still the pepper me for body now.

So na bc ur experience bad mean say "naija sellers" are bad. Most ppu duped under lithium are those with low knowledge on the product purchased. Most ppu need to understand basic knowledge on batteries lithium or acid. This knowledge will make you ask sensitive questions b4 making purchase.

Valto:
sorry for your bad experience, but wrong assumption bro. people still use brand new grade A cells to couple, i order cells from reputable Chinese suppliers (docan,shenzhen starmax, shenzhen xuba and shenzhen new deriy) most of my cells have capacity test performed on them, and they are all above capacity with very high cycles and authentic QR code. i use the best Bluetooth bms, pure copper battery terminals, thick copper 10mm, 16mm,25mm,35mm wires depending on battery capacity.
Premium lithium battery packs are pricey, but better soup na money kill am!
Never will u open up my pack and see low grade crap cells

You get time to they explain o.
There are fake and original humans.
Those who buy from you will understand.

mctfopt:


But if you are offgrid, and your CC us compliant you are good

True.

mctfopt:


All inverters may work with lithium, but not all inverters charging voltage profile is ok for lithium batteries.

Very correct.
Charging profile.

Drgreatone:

That means you have to factor in an inverter that can work with lithium so u dont end up spending again later.

All inverters work with lithium

Gradually, dollar will get to a point no one will be able to order anything except super few ppu.We would be forced to develope things locally.

b0rn2fuck:
see as this one spoil their market..lol na Good things sha

Na my oga u dey call this one?
Be kiafu

ZIKEYBOY11:


Thanks for the response I need min of 8 pieces.... I'll be using it for an hybrid 5kva 48V inverter.

The 300w 24v is about 50k from the seller in Alaba Lagos

If it is from Alaba...e go hard small o.
But definitely not Canadian. Na sticker dem put and e no reach 300w probably 200 or 190w. If the set up is for client DO NOT but na personal use go for it. My opinion.
