Tried to subscribe to the 20MBps plan and the plan is no longer available. One now has to do the 35k 40MBps plan. Airtel no try abeg...

It's so Sad, The 20MBps is like what everyone needs, but its a demarketing for other providers.

I guess it is a regulation issue, cause no other provider is that cheap.
35K Seems to be the benchmark for true Unlimited plans, Unless it's Fiber which is a fixed location.
Unlike routers that can be moved around.

Is this inclusive of shipping and clearing or just buying cost?

If someone using Starlink ever tries a local network, they won't sell their Starlink.

I have an iPhone SE 2020 , if you would be interested, it’s very clean , I’m in Lagos

how much?

firstpregnancy:
32 inches Lg tv
New
100k
Led
For sale
Location: Lagos state.

Is this real 4K? 32" TV with real 4K at 100k is rare.

Drgreatone:

Unless those sunkings are crazily expensive... The 3.5kva inverter and panels no reach 3m na

Add them up

Sunking no be DIY packs Lol

durodee:


The money not much o! Just like 11million sir!!!!!

Well, going by 10KWH LFP Sunking, 3.5KVA, and 4500W panels, for 11M is not bad, similar prices on Sumec Fireman, Prag, Pylontech, Fouani LG, and co.

Please house help me solve this issue o. A neighbour came to my place and loved my setup . He has an hotel and he wished the following loads to be carried for 12-16hours :
All lights-about 100 pieces of 10watts
Three freezers ( I don't know Capacity but medium capacity)
27 fan -ceiling type
28 big tv - about (36inches I think)
And borehole pumping machine 1.5hp for @2-3hrs per day
I estimated 6-7kwh of load at full capacity
Na so installer brought:
12x450w panels
4x2.5kwh (10kwh total) Sunkings batteries
3.5kva inverter.

I have advised my neighbour to request for his money on, because Na fight go end that relationship!

Incomplete information, we need to hear from the installer as well, we remember the story of 800K stop-gap to power PS5 for 16 hours.

How much was spent?

Sankabson:
Hello House,
Please I have an inverter I'm looking to upgrade. I really don't know to explain this, but I have added pictures for clearer information..

There's 8 Panels ( 5 Panels of 300watts -3 Panels of 150watts)
4 Turbular Batteries.

I want to upgrade to like 7.5kva. I have a 3 bedrooms bungalow. And 2 ACs of 1hp and 1.5Hp.

Please, I'll appreciate your advice.

Full upgrade means new hardware, your old hardware needs to give way!

What type of ACs are these?
A 6KW Growatt Hybrid Inverter can replace 7.5kVA with an Inbuilt 8KW MPPT.
Batteries must be LFP at least 15KWH, with Solar Panels at 5KW minimum.

TCD:


Hello Chief.
I'm curious. If batteries have short shelf life, how do manufacturers and sellers store them in their stock before sale which may take months?

That's why some batteries fail prematurely even when you buy them as New, dead of long storage!

Xanderone:


Hi. Please can I get the link for this "Sako" guys? I want to check it their solar panel offerings and prices.

I'm hearing of them for the first time though.

oh my, see how product reviews turn advertisement for SAKO .
It was shared here
https://www.nairaland.com/390522/solar-energy-complement-fta/1675#129600884

Parser:


Sounds good. Pls how much did you get your Sako and the panels. Can you give us a breakdown of the cost implication of your setup. Are you using Lithium of Lead.

2 Million Naira, 24V 3KVA Inverter, 4X 410W panels, 5KWH LFP pack. all Sako
check the previous post for Sako details, prices are not fixed.

jonescosmos:


Abeg make una help me look at this again, maybe na my eye dey pain me or some cells are hidden under that bar. If so, who would do such a DIY? Anything that would cross the terminals of a battery cell is bad, no matter how insulated you might make it. Except say that Bar na plastic.

It's obvious that cells were under the bar, that space cannot be empty, because all cells are welded.
Its to hold the cells from moving around.

[quote author=jonescosmos post=129770407][/quote]

its left side has 2p8s, right side 2p6s.. that's 28 cells, there was a cell holder at the center of the pack. Note, that these are laser-welded packs.

mctfopt:


Whosoever goes to this location should update us on how this abracadabra was done as I've asked this same question.

Did they do 16s and decided to run 8 cells in parallel to 8 leaving out 8 cells with no parallel?

Interesting what some DIY has under the hood the main reason I do ALL MY DIY from beginning to end.

there is no Abracadra here, he is running 2p14s. that's a 14s NMC cells

there are several types of Lithium packs. 48V
Li-on/NMC - 14s
LFP - 15s (48V) 16s (51.2)
LTO - 20s
Sodium ion -15s

What is/are the function(s) of the AVR/current limiter in this particular setupm

Attached is one of the functions.
its a Voltage regulator, Current limiter, Grid Delay, volt and current meter, and shortcircut protection.

zeestone99:


I hope you have Avr/current limiter installed sir

Dem no dey tell person oo, I just dey observe am.

Amador1:
Hello good morning everyone.
I’ve just spoken to the Jos guy this morning and he said I should take the battery to someone on his team here in Lagos to help check it out. He has sent me the persons numer.
I Will be updating the group on the outcome. Thanks to everyone for their concern and advice.

perfect

Amador1:
Hello good morning everyone. Please I need you advise.
Yesterday I noticed the display on my battery was blank and immediately I opened the jk bms app on my phone and attached is the screenshot what i saw. Since yesterday my battery has refused to charge and I don’t know what to do. I got the battery from the Jos guy two years ago and I’ve messaged him on WhatsApp and tried calling him too but he’s not responding. The battery is reading low voltage on my inverter now but on the jk app the battery voltage is high.

What voltage is the Inverter displaying?
wait on Jos guy to also reply, he might be busy.

One Cell is high than your Charge Mosfet is OFF, so no matter what BMS wont allow Charge, so allow the batteries discharge.

Danibestguy:

Wow. Abeg what's the Voc of the panels and how many panels?

I provide on pages back..

Danibestguy:

So, no need for me to have the nominal voltage of 240dc? Na the nominal dey gimme headache.
See this data sheet as well. According to this data sheet, I can even use the inverter with just a panel right?

I have shown you a picture where charging is well with 113V and even less.
and 1.64KW panel deliver 1.47KW at that 111V..
so your 240V nominal headache I don't understand

swagifted:
to be honest , if nigeria had net metering and the grid was highly reliable and also the agreement is 1kwh for 1kwh (i supply the grid 1kwh with my solar in the afternoon and the grid gives me back the 1kwh in the night), i will not take a hybrid over an ON grid inverter, the grid is essentially my battery so why spend so much on batteries?....as much as i love hybrids(because nepa too de take light), they don't last as long as on grids only.

your Don't last is too generic. Provide detailed information.

Danibestguy:

Alright. Thanks.
But can 2 500w panels start those inverters? If it can, will it charge at all?

There are low Voltage MPPT and there are High Voltage MPPT.
you select based on your needs.

there is 100V MPPT, 2 panels works
150V MPPT, 2 panel works
30-400v MPPT, 2 panels works
60 - 450v MPPT, 2 panels works
90v - 450v MPPT 4 panels or more
120-450v MPPT 6 panels or more.

options plenty.

Jefferyzz:
2 440w - 260k
1 powmr mppt - 103k
3000w easure sachet inverter - 92k
Cables n odas - 70k
Transport - 10-20k
This is most likely Ur cheapest route

so he won't use grid or charge with the grid?
he will have to use ATS or changeover just like generator

Danibestguy:
Hello. I have a 24v 100ah lifepo4 battery.
Constant load - 240w which is just a fridge and a fan.
I want to get an inverter to match it. I'm also planning on getting panels later on.
Please note that we get up to 8hrs of grid light daily.
Is it advisable to get an hybrid inverter ?
Considering that I'm staying in a rented apartment(limited space), will 2 500/550w panels in series be enough?


Budget is 500k.

Hybrids are here to stay and have stood the test of time already. why are people still contemplating?
Hybrid gives you an Inverter, Charger, and MPPT, cheaper than any standalone.

example with 250K. you can have
a 3kva inverter with 60A charger,
80A MPPT, go and price stand-alone equivalent.

Hybrid allows you to customize slightly when grid charge, how much grid charge, when Solarcharge, Only Solar charge during the day and Grid charge in the night, etc. with standalone, you need to have good know-how and other tools to achieve these.

Eagba:
Please house I need answers er with this;
My wife is running on a budget, so she's thinking of getting solar panels for charging to complement her pos bizness.
Now the thing is, she want to know if she can get only solar, no batteries and maybe charge controller for charging of customers phones and devices.
Thanks sirs and mas

You want to charge 25 phones simultaneously, that's 250 watts of energy if each phone takes 10w. that's base charging 2A 5V.
Plan at least a small battery to serve as a buffer for cloudy periods.
Plan for LFP backup 12V, 50AH, or lead acid 12V 100AH will do for a start.
500w Sachet inverter, you can't run DC-DC due to the number of phones.
12V 60A PWM charge controller,
2PC of 180W Solar panel.
with 500K you will reach somewhere!

durodee:
I am not aware that CC goes bad because it was not used for a number of years.
It does not have an internal Battery that runs flat or anything like that.

Once they gather dust, you will see rust and all.

obinna37:
I'm not doubting you,the guy himself just they reason where him go see #150k to buy one more panel now, already his plan is to buy three panel, but due to finance,he decided to mount this two, maybe later he add the remaining one,now the two no work.abeg our elders in the house make ona put mouth for this matter and help a brother

Sorry I was in a rush to reply without complete information, I have attached the manual showing how many panels he needs, he can push for one more panel.

obinna37:
pls tell me it's true,he should add one panel,I don even tell him,he will need more four panel,my guy cut phone for hear

he should check what his manual says if in doubt..
this is the manual attached.
they used minimum 4 panels 250watts, of 30Vmp.. meaning 4 X 30 = 120V..
the 545 has more than 40Vmp X 3 is 120V.

bbally:


He needs panels in series that will produce 260v and above, that's the disadvantage of these HV hybrid inverter compare to the standalone CC for small size installation.

Not 260V.
we have High voltage starting at 36V now.
this is Sako 1.64KW watts panels producing 1.43KW with only 4 panels rated at 31Vmp
total input is 113V from PV
