Thank you very much for your reply.

Please explain further.


I thought lithium is more expensive?

Please explain further.

wetin I wan explain again ?

I thought lithium is more expensive?

YES lithium is COULD be more or less expensive depending on quality and source.

1.) Please the charge controller and the battery, which brand do you think I should go for?

Iinnov8:
Joykoo 25.6v 100ah (2.56kwh) LiFePO4 battery with remote monitoring through bluetooth phone app, external digital voltmeter and cable lugs

4.2.0

Phone app shows the following:

* State of Charge (SOC)/Battery percentage
* Overall voltage
* Voltage of individual cells
* Current draw
* Total Power consumption of your load
* Backup time left based on load
* Total cycle count (number of times you have charged and discharged the battery)
* Duration left to full charge

Is this battery better than lithium batteries? And what kind of inverter can be used to power this, plus solar. Kindly give a list of what needs to be bought alongside this to power a house. I'm interested in getting it

kuss:
Are you sure you chatted the right person
Their contact person is a woman and she is in china
I bought 150ah in December

I chatted the right person her number is here on nairaland.
I chatted and also spoke with her several times on whatsapp calls.

The prices have changed as today.

See screenshot of my chat with her.

I even sent her this price list on nairaland, she said that was old stock.

The Itel power tank is a low budget solution for intending solar users.

Cost break down ;
Power tank 500w (1kwh) 304k
Jinko 535w bifacial panel 107,500
Installation and materials 130k... Length of pv cable caused the price hike.

Loads.. Normal 32 inches tv
Small Home theater
Lighting points
And a standing refrigerator.
Dc standing fan.

Gets filled by 1pm due to lack of early morning sunlight (Should fill faster in a better location)

A full charge lasts through the night with the above loads mentioned leaving at least 35% charge, although TV and home theater goes off latest 11pm

If you're on a super tight budget and this solution can work for you, then by all means go for it. Highly recommended !

Please I have two questions;

Does it really full by 1pm? What if you're using it while charging m

If it's full and there's no sun again, and I plug my itel power go (that's the new 100k power bank) to charge it, plus my laptop and fan of 30w, can it still last throughout the night?

with your budget, and when shopping for used items, na wetin dey you go buy. Justt ensure it's MPPT and probably share with us the pictures before making payment

Okay thanks for your input

I have a 2000w inverter and charger.
So I need a battery pack to work with it.
The options I have gotten so far is

1. 12V 104ah lithium ion battery - N185,000
2. 12V 100ah Lifepo4 battery - N203,700

Which is advisable I go for.

Firstly:

12v inverter
Low Voltage alarm - 10vdc (± 0.5)
Low Voltage Shutdown - 9.5vdc (± 0.5)
Overvoltage Alarm - 15.5v

12 v Li-ion (3 series) charge parameters
Discharge cut off @ 2.7v each - 8.1v
Fully charged @ 4.2v each - 12.6v

12v Li-ion (4 series) charge parameters
Discharge cut off - 10.8v
Fully charged - 16.8v

12v LFP (4 series) charge parameters
Discharge cut off @ 2.5v per cell - 10v
Fully charged @ 3.6v per cell - 14.4v

If you examine the parameters critically, you'll realize that Li-ion falls out of the upper limit or lower limit voltages (depending on the string) of 12v inverter. However LFP 12v falls perfectly within the voltage range of most 12v inverters making it the best choice for lithium chemistry to use with 12v system.

At 24v and 48v system, Li-ion chemistry attains the range perfection that it lacks within the 12v ecosystem.

Secondly:

Li-ion chemistry is around 3000 to 4000 cycles. LFP, although with lower energy density than Li-ion still has better cycle at 8000 to 9000.

Verdict - 12v LFP

New or used and how much per one?

Barely used in MTN lumous. In great condition. Capacity tested.

1k each.
Discount available with more quantity.

bassdow:
for those looking to buy used Lithium cells especially those cylinderical ones e.g 18650 , see eh, just go to where they repair laptops, either get those bad laptop batteries for FREE or pay a little token to buy them e.g 150 naira per pack AND a single pack can contain like 8pcs or more.

Most would gladly give you for FREE if it's just 2 or 3pcs.
Additionally, to get much more, tell dem it's for school project. Most times, na Aboki go still come buy them.

Open them up and take what you need.

Most times, you end up with perfectly quality cells where it's just a single cell that rendered the entire pack unUsable.

in fact you could even use the pack to construct things if you're good with thinking. except you're the kind that have outSourced your thinking to daddyGO or the likes.

I come in PiSs

Risks:

1. You may not easily discover cells that suffer from thermal runways - quite a dangerous scenario speaking fron personal experience with 18650 fire

2. You can be okay with that approach if you're using it to construct small packs of 6, 9 or 12 cells. By the time you're going big with dissimilar capacities strung up in series, you can also end up with overcharge/overdischarge of dissimilar cells which will shorten the lifespan of the pack.

If you have a capacity tester though, you may be able to group together similar cells.

Oh, sorry…. I bought Apex from Jumia

How has it been so far with the product?
What rating? Is it wall mounted? Is it performing well to expectation at low voltages

time to start hoarding cells.

with this, He's locked-in with no room for growth.

there isn't much 300k would do for him.

with quality used items, there's definittely room for growth unlike a baked All-in-One. My opinion though

that's true tho.

Hello people,

I need advice and recommendations.
I want a battery backup system, hopefully to expand to full solar later.

I need a system that can charge up in 4-5 hours. It should carry appliances for minimum 3 hours on full charge.
Here's the Load:
Freezer of 110W
Laptop 65W
Phone + Light, Fans, etc 100W

I won’t be going to arena anymore, I think I will diy with this. This is the best solution imo. Ordered 2 already

so I received these and have them installed but the inverter didn’t turn on at all. ( MY warranty is officially dead and gone from Haisic)


I guess the inverter works like a computer where it has to check for all vital parts before it turns on.

My next line of action is replacing the fans with these fans I ordered along the speed governor

New replacement fan specifications *2
80cm*80cm*10cm
12v 0.13a 1.56w
17.8CMF airflow

The Haisic follow come fan *2
80cm*80cm*25cm
12v 1a 12w
115CMF


I don’t think this can work, the downgrade is too much.

SolnergyPower:
How much?

12v 100ah (1.28kwh): 220,000
24v 100ah (2.56kwh): 420,000

They are actually Lithium batteries (LiFePO4) made with Grade A cells. See datasheet attached. A capacity test has been done on them, see links below, and we will be conducting a live strip down test on them soon.

And yes, it can power your house. You either get an inverter, AC charger and solar charge controller (as seen in first picture below), all of which i can provide, or get an Hybrid (all-in-one) inverter. I have a Haisic 1.5kva available for 190k. See picture below

Okay can you please give me a quote for a complete set up which includes solar panels. I need a minimum of 2.5hwh lithium batteries

I gave an idea on this earlier, you don't need to replace the fans either. You can quote me on a dead thread with your Whatsapp for guidance

You are not doing things right bros.
Ur component should be in between the fan and the inverter board.

yes i know. I need guidance now. The replacement fans can't handle this job.

I've coupled everything back with the old fan pending new ideas.

dollarnaira:

no i did everything exactly by the book. The component was in-between the fan and the board, the inverter didn't turn on at all.
