Lol. You are funny.

I know both chemistry are different. I did long long ago. I am not an empty youtube gobbler of theories.

What i was trying to point out is that for you to build your 340 cells pack or equivalent, you do not compulsorily need 340 cells. lol. Instead you can use 6 cells of 46AH capacity in 3S2P configuration to achieve similar kwhr or whr accordingly. You just need bigger cells and that's what i pointed out to Tetralogyfallout. There is also 4680 of around 22-26AH pioneered by Tesla.

Where you wan dey find this cells?

In Africa/Nigeria, it's always availablity that is the key driver of our planning or design.

Your contact details is in Morse code.

I've been trying to decode it for several days now.

I need to reach out to you soonest.


'lie, lie lie' is where the problem seems to be.

Good afternoon boss, thank you for your swift response yesterday. Let me give you a little back story. Those three used batteries were given to me and that gesture stimulated my interest in installing an inverter. Appliances to power are plasma TV, dstv decoder, 3 ceiling fans, deep freezer and five 5 watts bulbs(although all these appliances will not be used at the same time). The plasma and the freezer(140w) are the reason why I'm considering a 4kva 48v inverter. But with your comment about adding a new battery(for series connection) which will negatively impact its performance because the other batteries are used, should I downgrade the inverter to 2.5kva 24v so that the 3 used batteries can be run in parallel and series connections to make 24v? Would this setup still power the above appliances? Which inverter model would you suggest? Note that the system will be charged with the grid and sometimes, generator(3.5kva)-no panels.

Get a 12v sachet inverter and a separate charger, it is easier to manage and has low entry cost.

Just incase their might be need to upgrade, it's easier to sell off the inverter (You can work on a swap deal if you buy from people on this thread), battery(obviously can be sold as scrap) and even charger(charger might be what may take a longer time anyway).

If you decide to use a 24v setup, you will be forced to use just 2 units of those batteries or you but an extra one and add to the one not in use

3ace:
Hi chief, please I need your advice. Can a 4kva 48v inverter work with three 220ah 12v tubular batteries? If four batteries are compulsory for the setup as suggested by a friend, can I just buy a new 220ah 12v tubular battery and add it to the three batteries? Note that the three other batteries are fairly used for two years but still has a decent power backup. I hope combining old and new batteries will not speedily wear out the new one.

The old ones will pull down the new one to its owns internal resistance (the capacity of the previously acquired 3 might have reduced)

Since the inverter is 48v(it will require 4 batteries in series) where as, the 3 batteries in series will only give you 36v.

If the inverter even manage to work, it will not output the complete AC voltage.

RickyM:
Which state are you so I can know if it will be viable, I’m in Ogun state Abeokuta/Ekiti

Lagos State presently

iraybuju:
Oh you are a repair man. @ where? What’s your contact ?

Lagos presently. No. Is in my signature

Tdoctor:
Bro. I was asked to contact you for victron repair. Smartsolar charger

I just responded to your mail

RickyM:
Do you repair psw satchet inverter? Those type Valto sell?

Yes chief

Abeg share ideas. Na Tinubu dey on seat.

The owu breeze is getting colder

iraybuju:
👏👏👏👏✔️✔️✔️
Thanks man it worked. You are a great man. This was becoming a serious headache for me

Which combination worked?

ZaraArewa:
Forget about my reasons obnoxious, the north has not really been fair to we the women, they only see us object for s*x, they aren't giving us the opportunity to show them what we can do.
Some of the most brilliant women i know are from the north but they are been oppressed😢.

If try to seek opportunities to show what you are capable of, Na haram.

I personally feel that's a way of life that has been passed down from ancestors to ancestors.

If you decide to deviate, just do am for only yaself, mind you you will have to question alot of things you believe in.

ZaraArewa:
In the north where i grew up, it's a taboo for a lady/woman to moan while being pleasured by her partner. They see it as haram, saying women are not supposed to show how excited they are.

You women from the south really don't know what Allah has done for you. Thinking of relocating to the south. Because I wish to express myself while being pleasured.

What's holding you?
But your reason for migration self

kewhos:
Good day everyone, please I’m looking for a good installer in Warri. Kindly indicate if you are an installer in Warri or recommend me one

Chief greetings reach me out if you have not gotten anyone yet.

Samsungx2:
Has anyone tried RAVEN, give it a Trier. there service is top-notch.

I left them after they did an upgrade on their system and my 5k miss(they started using phone no. Too for acct).

I have dialogue and provide payment receipt they still claim it was not received, I just quit using it..


Aside from the they are okay.
I used this their daily saving features nice apk then don't know now

Obviously the dispatch.
You will have time to do other things.

Where problem go dey, Na if you no dey maintain your vehicle

HeavenlyBang:
Where are the 96v inverters?

There used to be 96v upto 120v TF based inverters but now they seem to be very special request.

Following .

Will love to get more information
Thank you in Addy

Am just curious, why do most battery within Nigeria all stop at 48v and not 96v.

Most commercial/industrial setups might require higher voltages, but due this low voltage limitations implementation and design might be rigorous

officialfestus:
It does, once used a buck convert(20A) to step down a charger of output (14.4v 20A) to 12.6v, hoping It wasn't going to alter the amps, but unfortunately the highest amps I could pull using the buck convert was 10Amps.

Oh.

officialfestus:
is it possible to reconstruct the voltage to 12.6v with altering the amps?

I don't think it will alter the amps

Elizkid:
How do I do that?

My battery is 100ah lifepo4 12v

Just buy a good BMS it will create an open circuit when the charger is trying to over charge the battery.

Besides I have only tested it in suoer 10A charger

dollarnaira:
Can work for Lifepo4 and Lead acid.
Not for lithium ion
Not for lithium ion
Not for lithium ion

It can work for lithium ion, but you will need a good BMS.



Aside from that you can reconstruct it to supply 12.6v for lithium ion charging

Drgreatone:
Thanks boss.
So i wanna ask, I have this 2kva sms inverter that i have returned to the service center about 4 times now and same issue still remains. Its over estimating the panel input, imagine 3pcs of 300w giving out 2kw on the inverter plus batery isn't charging still. Ur help/advice would be highly appreciated.

If it's over estimating input PV power, it's likely a sensor error tolerance fault or a microcontroller based fault (it's usually a bug in the programme)

When you say battery is not charging, do you mean it's not pushing amps?

Happy Sunday pals and oga I get plenty for here .

So in the spirit of technicality and sharing knowledge, I have finally decided to create a YouTube channel where I post just repair videos(while offer last) but you know Wetin weak me pass?

Na the video editing , for now we just need to manage what we see .

By the way it's going to be purely Pidgin English for the voice over( I am obviously going to stress other folks who are not Nigerians)

Then I will also be providing a PDF free downloadable documents guiding with images every points/parts that needs to be checked.


Why have I decided to do this?

I couldn't find a Nigerian YouTube channel that successful taught repair (the technicality) we have lot explaining block diagram and all....

But I go cast everywhere for free meanwhile I go need still tender official apology to all the senior men whey dey the business....

But till then, you can always ask your questions and I will definitely find ways to help out if possible

Greetings my leaders, please where can I get 3s balancer within Lagos please refer me

Mehn this log book still exists .

Have compltely forgotten about it

gadgetplanetng:
Pls what's your location so I send this across from Port Harcourt.

Am In Lagos State presently. If you are within Lagos it will be easier

officialfestus:
24v 2.4kw

Very nice build

This will be faster for commercial build

nickae:
Still trying to understand what is going on.

I made inquiries to GTFundManager for Dollar Fund, they provided a FBN Account Details:
Beneficiary Account Name: FBNQUEST TRUST/GUARANTY TR USD FUND
Beneficiary Account Number: 0012706025
Beneficiary Bank Swift Code: CITINGLA

I inquired the same Dollar Fund from FBN, i.e. First Asset, they provided a Stanbic IBTC Account Details:
Account No : 0005513686
Account Name : Stanbic IBTC Trustees/FBN Blended Dollar Fund (Specialized)
Beneficiary Address: First Asset Management, 16 Keffi street off Awolowo Road, Ikoyi-Lagos

Does it mean STANBIC is the biggest player here?

I think it's the custodian account details that's been shared

Just like on Stanbic MMF UBA is the custodian...

I think it's something similar

isangjohnson:
Any installer in Ikeja axis of Lagos State?

Not in ikeja, but it's within my vicinity

We Nigerians praising inverters like Growatt, SRNE etc which are cheap and high frequency shows our shallowness in good solar applications..

Growatt in the west is meant for the poor who can't afford solid inverters and for 80% users they die on them after 18 months or 2 years.

Manufacturers of inverters make it clear to users not to use high frequency inverters for heavy loads. They are not meant for devices with inductive loads like fridge, freezer, pumps, AC. They are not meant for offgrid home applications when you know you'll use the loads. High frequency inverters (without transformers) are for light equipments like lightings, TV, phones, laptop, security cams etc. That's why they are Damn cheaper than low frequency ones. There components are not meant to handle heat for long.

But for us, we will use them with AC, pump, freezer etc and since it's working (of course it'll work), we claim they are the best. But they won't last on the long run.

A low frequency felicity inverter is multiple times better than your highest brand (Deye, Growatt, Tesla) high frequency inverter for offgrid use with heavy loads.

If you are going for offgrid, spend the extra money and get yourself a low frequency transformer based inverter. They are made to withstand heat, dust, heavy loads and harsh environments.

If you need inverter for your office, farm or home, for just light, laptop, TV, printer etc. No need to go for low frequency. Go then for high frequency inverters and save cost

Normally LF inverter are the most rugged everyone knows this. It's just that they cost more.

Besides maintenance wise, they are cheaper too
