Lol same Airtel wey dey suffer me as of yesterday my network is slow af imagine getting only 250kbps

leave dat guy make e de yarn wetin we already know.

airtel will work differently in several states. u cant say the same for starlink... starlink will work anywhere it find itself.

samnaija:
I keep saying you make assumptions anyhow. Has far has i am concerned i built my bank to give longevity. If you started on a not serious note it is your fault your battery died.. I started using my battery during covid 2020 .

16 in number total. And confidentiality no issues, 24hrs light , power any device in my house..

Design and size is important. Dont anyone fool you. The size and design of battery banks are important for both lithium and lead.
Do not believe all this label placed on the batteries body.

In as much as i want to agree with u... the price of obtaining 16 tub batt (15.8kwh....50% dod) @ say 250k/290k (average/authentic brands) per battery is not worth it in 2025. u can check out prices for 15 to 17kwh battery packs and ask urself if its worth investing in it.. u also tend to spend more keeping these batteries balanced... what abt the space consumption, Most installers never look @ C rating of most lead acid batteries.. i think that is where thier problem starts from.. its easier to get away on lithium packs with gud bms. All the same lead acid works and still works

ManAdii:
My next target now is EG4 18Kpv or flexboss 21

pv voltage input is one of 2 diference btw this and deye 16kw

dollarnaira:
All batteries including car batteries will serve you within short period of installation. Which will stand test of time is the question that no longer beg for answers.

Let me push small fear into your spine.Unless you power just tv, charging, and bulbs will this set up do 2 or 3 years or less with careful pampering before you will notice large difference in capacity. Raining season is even coming....how will you full charge it?Sulphation will kill it by then.

If you add freezer, iron, etc be rest assured your system will fail in less than a year.

Assuming you didn't know this thread before now it would have been a different issue of "had I know". But you deliberately shot your upper limb with your eyes opened .

2 tubulars is roughly 550k or more, that is more than the cost of 16 pieces of 50ah LifePO4 at 48v with more than 12yrs life span mixed with rugged usage along with washing machine, freezer, iron, all electronics etc without pampering. Today is April 3, 2025 see you in 2026 for update.

oga evangelist . take am easy lol

Chizo11:
SRNE MPPT solar charge controller
It has User defined settings of 9v - 32v
works for lithium NMC / lifepo4 from 3S - 9S
I have some of it for sale

specs pls

Iinnov8:
At the moment, no. But it is a possible consideration for the future

.

Y are invisible individuals charhing people high fees just to activate their starlinks devices. Fees go as high as 150k to 200 in the name of activation fees. Subsequent subscription is about 90k. Some people don turn clients to their employers de collect monthly salary.

Y Nigerians b like this...

Abeg folks in the house, anyone with useful information on this development. Sometime ago I read about how you can add another starlinks device to an existing account. But can't remember. I guess this is thenee mode of activation starlinks devices in locations were there are no service.

Sims like no jinko panels btw 555 to 590w. anywhere..

Techland out of stock
Fouani out of stock
Genexx out of stock

Jinko de cash out seriously

shopnig24:
Yes

pictures pls

ibietela2:
Back door what?

i call it back door.. but it seems part of starlink management for nigeria has been subleted to a 3rd party

Valto:
hmmm, Let there be peace brethren.

lol..abeg nor make me laf

Dam5reey1:
Look for ways to discreet me!

try harder and implicate your oga more.


Make your oga posts his cells make we see.

ur strategy is one full of bitterness and envy.... u cannot sell to the whole Nigeria........i have told u pull resources and start selling ur own cells or packs 4 piple 2 buy... since u feel others couple low grade cells to selll to users here... Not everyone can go through the DIY route.

clevermugu:
so all these rants about Valto yesterday, calling him very greedy,is all about introducing and start marketing your preferred brand. your deriy pack is even pre-order. there is a huge difference with buying from China and waiting for 3 to 4months and buying and recieving in few days.. note: no one is trying to shut u down, but u don't try to discreet others, in other to promote yours. i remember the prices of your 280ah cells and sunlight batteries , during your back and forth with isangjohnson. the prices were not cheap.

e thinks by discrediting others, he will grow.. not everyone is dumb here not to read in btw the lines...if u like use alternate monikers to ask questions and answer dem.. we know its u.......

BigDickProblems:
Please you guys should stop shutting Dam5reey1 guy down. I don’t understand you guys at all.

I am here to learn and the most interesting things I’ve learnt so far are from him and some other folks here-his YouTube videos on battery capacity testing and other invaluable information are usually well detailed, educative and interesting for a curious mind like me.

He can point out anything unusual from any brand whatsoever, and you can correct him constructively in a diplomatic way if you feel he is wrong. Don’t make it look as though it’s a personal thing.

I don’t know about Valto, but with the little I’ve seen here, a lot of people can vouch for his products; of which I love so much. I mean, obviously he is a good producer.

But do I learn a thing from Valto so far? Except for him proffering, advertising and prescribing his products here, there is nothing I’ve learnt from him (perhaps he used to, but since I joined this thread, NO).

And much like any company, anyone can be checked for. If a test is done on his product, are you not supposed to open-mindedly accept the critic’s observation instead of saying it’s a personal beef?

But I am just speaking my mind. I really love learning, and without people like him questioning certain observable norms, it’s becomes a thing of everyone accepting anything that comes by.

Please stop shutting him down. I don’t know him from anywhere, but please stop shutting him down.

wen u re relaxed. Find time to read wat u just wrote here..sims u posted in a huri

Dam5reey1:
What is bad belle in your context?

You are not reading with open mind

React to the advert, I attached screenshots.

The contention is about the expectations that was created.

Please start pulling resources 4 d sake of d gp den you can sell cheaper cells to folks that needs it. Start your own charity organisation

Dam5reey1:
Na person wey carry market to DIY group wey people are woke!! Dey look for trouble.

People here want to save cost and learn, thats why they are here. I have shared direct dealership prices to many..

On my videos, I revealed the Cworth's 12V 100ah original price, which is lower contrary to what it was advertised here for at a time.

I have indirectly spoil market for persons, but no be my fault its a DiY group.

Guy this bad bele nor go help una 4 dis gp. There are several sellers on this gp. If u don't feel comfortable with a person's price simply move to the next. Several links to Chinese battery sellers have been posted here. Simply buy ur cells n import them, couple ur cells n relax ur mind. FYI felecity 15kwh battery is 3.1m naira. From thier outlet not alaba folks. How else do you want a diy pack to be more cheaper dan dat of valto.make una de use una brain 4 here. So na DIY thread com min say dem de pik cells 4 ground?

KA24DETT:
LOL.. thats not true. it will clip. I do run my 10kv hybrids with 33,000 watts of solar panels connected. MPPT pulling 120amps from dawn to dusk. One year and still working. In my system, none of my systems have less than 30,000 watts of solar panels attached to it and i have 8 systems running. I can attach videos.

what brand is this 10kw hybrid inverter?

mangolpupa:
I'm not satisfied with my solar harvest. Have 24 panels - 8 panels in series x 3 strings. But I've observed my batteries don't get fully charged most days. The few times I've checked each strings hardly generates constant 2.2kw which is under 50% of combined string connection.

600w x 8
560w x 8
560w x 8

Yes, I bought from Fouani. So sure of the panels.

anyone with knowledge/experience of ichecking the system & improving such situation can reach me on
WhatsApp 08one467two853six.

Hmmm but if I may ask

Wat is the spec of ur inverter,

panel orientation,

cable size used...

Are ur panels dusty?

Wat is ur battery capacity and its dod

Wat is the caoacity of ur day time load

Has it bin like this from the onset?

mctfopt:
70% of Nigerian Renewable Energy installers/electrician's needs to be retrained. Someone today installed 2s 6p with solar panel of VoC 40v on an inverter with MPPT range of 120v to 500v and wondered why it was no longer charging batteries by 3:30pm.

His reason: system voltage of 24v requires 2s.

Ok.

lol

there is something going on now... thought i should share it wit everyone.... although am yet to setup one.. but an installer friend of mine has been installing difft starlink kits since december.. we refer to it as the backdoor...

cons of this installation
1.. u cant change ur wifi password in a hurry
2. u dont have access to your dashboard
3. chances of you receiving new starlink kit to me is slim cos u need ur dashboard to login and contact customer care ( still asking questions)
4. cost of activation varies from 200k to 250k (inclusive of the fist month subscription)
5. price of monthly sub is 90k


let me hear ur view on this. will be activating one soon

Mrreed:
It will help if you also stop being defensive. The group is still a DIY group and learning place for many

if u cant read pls skip my post

princely009:
Dam5reey1 clearly stated that his post is for educational purpose only.
Besides everything he said there is totally true becus i experienceed it with one of my lithium batteries just last week. The battery was barely getting to 100% SOC daily due to undersized panels and a high dust in the area.
Last week, the inverter cut off power, beeping low battery bt the display on the battery was at 48% SOC and i was surprised.
I called Valto whom i got the battery from and he told me to charge the battery until it stops receiving current and also to ignore the display on the battery even if it is showing 100% and charge the battery until it stops taking current that the BMS will recalibrate itself. I did exactly as he instructed and everything is back to normal. The BMS has recalibrated itself.
I believe Valto didn't explain all the details that Dam5reey1 went into in his post with me becus he knows I jst wanted solution and not explanations.
And before you say I am being biased myself, Valto is my plug for lithium batteries. I hav bought over 6 batteries frm him. Three (11.7kwh, 14.3kwh and 16kwh) batteries personally for myself, and more than 3 through my recommendations to my friends and installer). And all are performing excellently well.
Infact, I am planning to buy another 16kwh battery from him for a friend next week.

PS- I have oversized my panels in that location and my battery gets fully charged every day now.

checkout the meaning of constructive journalism and u will understand my point of view. Did he care to explain the root cause of the issue and proffer solutions to it? SOC drift is not a new thing in the batteey industry. It even happens to professionally coupled packs. His post portrays the view of a bad pack from the seller

Dam5reey1:
Good to be back again.
Back to BMS SOC thing.
This post is for educational purposes..

As a Customer service person, I support several brand now.
So a Customer reached out this yesterday and his inverter was showing 24.6V with 58% SOC on the battery.

To an average User, Our Client has 58% why is inverter showing low Voltage warning, was scared that something is wrong and turned off everything

So according to our client Sun has been poor and battery has not been charging well, So we checked the voltages and told our client your batteries are close to dead, but how do we explain this when battery is showing SOC at 58%..

So we explained LFP voltage curve blablabla. Client was convinced but not fully.

Fast forward to today.

Out of curiosity we received the video of the battery now at 100% but still charging at ~12.8A.

Upon inspection we saw average Voltage at 3.34 means this battery cannot be at 100% it just BMS fooling itself.

So we explained that Flat voltage curve of LFP and informed the client that the Battery will be Fully charged when the average cell voltage is at 3.45 and above and the charging current is Zero Amp.

Client now fully understand the whole LFP Curve and BMS drift.

if u want to discredit someone,please do it in a way no one suspects u of been envious.......

confluence:
how much do you pay for this?

10k...35gb
15k...75gb

like i said once its 8pm..... it becomes unlimited...... ISP Is vdt comm... u can google dem up.. and make ur enquires

QuoteJust1nce:
2Mbps * 3 devices = 6 Mbps maximum demand
6Mbps * 2 tenants = 12 Mbps maximum demand

Starlink on a bad day can still deliver nothing less than 50Mbps; leaving 38Mbps for you
On a good day, 150 - 300Mbps is not unusual, leaving 138Mbps - 288Mbps for you

Note that data usage is unlimited. You might need to reconsider. While unlimited data at 10k/2Mbps x 3 devices per month
might look good to them, there is still plenty on the table without hurting your own speed.

At least 4Mbps for a start per device; maxing it at 24Mbps
or 10Mbps per SSID maxing out at 20Mbps
This second option is preferred and each tenant can have their own SSID and share the 10Mbps speed how they like among
their devices.

But if you're on the roaming plan and in Lagos; soon to be 167k; all bets are off!
Good luck.

I have been using an isp on 5mbps unlimited bandwidth for about 4yrs now. During the day am pegged to a data plan but once its 8pm .. its unlimited. Serves me well but like all networks there are ups n down. I have my smart TV on it, 2 phones n 2 pc. Still consume up to 500gb monthly

Dam5reey1:
Na so jare people are too emotional.

I only show cell behavior if you discharge them below 3V, regardless of the manufacturer same applies across, if he read between the line he will understand say na only Cell I bought, the pack was built by me.

What I was expecting is a someone to come out and show me their pack at 47V, and lets see the Cells behavior, this thread is DIY where we learn not a market place. Where we market or demarket anyone.

I once mentioned this when there was arguments about cells grades and all.

I hinted that most LFP seller will tell you charge to 3.45 and cut off at 3V so as to cover some flaws. Now that is evident.

Many went against the Pack that can reach 3.65V without OVP getting triggered and condemn seller for selling a 14.6V charger.

ur charge curve shud tell u dat there is really notin 2 gain above 3.55v just unnecessary stress on ur cells.. same tin with ur discharge curve

Dam5reey:
@ Haykay2001
For reference, this was how a pack of cells I got from your favorite seller here looks like at the buttom.

u de fear 2 call names young man

redgem:
I contacted one of their technicians and he said the battery is okay....that it's normal for batteries to discharge except the system shuts down itself....

lol.. abeg how did u conclude the battery is discharging itself... let's start from there

bodeface:
Hello All,
Please, can you provide me with the Charge controllers with Maximum PV Voltage up to 450V ,available in the market
All mentions are appreciated.

srne

redgem:
Good day everyone... My cworth 2.5kwh LFP discharges on its own even with no load on it..... Please, is this normal?

take it back to cworth

Allem:
Enjoy, exactly the set up I did yesterday but valto, I don't know what I did to you oh. You dey always give me non sexy battery box. See this 7.1kwh as e fine, same thing you did with 14.4kwh I bought. I dey vex.

lol

Edrizz:
I will rather advice him to stay away from Sako n embrace a different product entirely, have had too many issues with them of late that even their support couldn't proffer solution to

can u go deeper on this. If support can't help u, can't the inverter be returned?
