Thing is, an All-In-One never gives room for growth + is rarely as performant as the shatndard solar setup where you buy your batteries, inverter, solar panels, etc all separately.

The only adjustment raised by @Dabss is capacity of the system (more like why go for inverter of 4.2kva when 2kva should do) BUT that shouldn't be much an issue.

BUT if at end of the day, you decides going for the All-In-One, it's still your choice.

Okay no problem.
Thank you very much for your patience. I'm going for the standard set up, however, I'll consider the 2kva because of cost

Hello everyone,
I need some advice from experienced members regarding my inverter setup.
I currently use a 1.2kVA Prag pure sine wave inverter. Initially, I was using a 220Ah tubular (wet cell) battery, but I recently added a 150Ah LiFePO4 (lithium) battery with built-in BMS.
Now I’m considering setting up a system where I can switch between both batteries:
One switch to select which battery powers the inverter (tubular or lithium)
Another switch to select which battery the charge controller charges, what sort of switch

You are wrong to do your maths that way and you also don’t understand the energy movement.

Let’s be generous to say that the owner uses a 15Watts chargers in his shop:

10 power banks = 15Watts by 10 = 150Watts
15 phones = 15Watts by 15 = 225watts

Total running loads at a time = 375watts per 1 hour.

Meaning that on the system is 375watts an hour. Nothing like 1kwh of power.

The power banks will take 5hours to completely charge while the phones will at most be filled in 2 hours. That 5 hours is enough to get your battery full and still charge those devices if you calculate well.

The duration of how long he runs the 375watts is most importantly based on his solar panels and battery bank. If he has solar panel of 1kwh, don’t forget that the generation of power on an ideal day is about

1k watts by 5hours =5kw

Meaning he has 5kwh per day. While his load is 375watts which will run for about 13hours a day. Meaning that 10 hours is enough for 20 power banks and the remaining 3hours (375watts by 3 hours) is enough for 75 phones.

Do your maths this way, gather enough research to know how many customers you will likely get a day and buy your set up that matches it.

Back to the shop owner and many others like him, they just don’t know the maths too, and they don’t like to ask before they get into it. Chikina.

Are we neglecting the amount of energy in these banks? u are converting from ac to dc, where are the losses in ur calculation.... what i explained above is based on energy and not power...

tziz:
Wow. Will 25mm/sq work?

16mm² can work too, you asked for the ideal size. Ideal is 35mm². But if you have 25mm², go for it.

I never knew that charging phones consumed so much power until a friend opened a charging shop near school. He runs at a minimum of 600W even on days when there aren't many phones. With 78 charging points, the wattage adds up pretty fast. He currently uses two old 220Ah tubular lead acid batteries paired with four 550W solar panels. Eventually, he will have to swap out those old batteries for lithium ones.

God bless you....
I was able to comment, then I saw this.
It's not as if the power banks draw their rate capacity in an hour, most of this power banks draw max continuous power of 20w

even me sef shock. U see those power banks, especially dose ones dat can stay 3 days give dem chance. Ur 15kwh battery go b like child's play

. I was speaking in terms of energy and not power. If I was to explain in power terms I would explain in that direction.

You meant total energy that'll be consumed after full charge of those devices, right?

I believe inverter capacity will be choosen based on the load max continuous power consumption + breathing room for the inverter.

OK Thanks Chief

Please first ensure the price difference between 2kva and 3kva isn't much. if close enough, then makes more sense going for 3kva or 3.5kva or go straight to 4.2kva or 5kva for a start AND upGrade when you get there.

GoodLuck

Where una dey see 15w chargers? Everybody just dey drop opinions lol.

The average chargers in the market right now are at least 25w, with some going as high as 40-50w power draw.

Phone charging business requires alot of energy, especially if you're located in a busy place that can do up to 100 phones and powerbanks in a day.

It's easy to throw words around like 2kva lol, try am first, body go tell u 😂. Better go and get a 4.2kva inverter if you're sure of 100 phones and above. That way nothing concern you with future upgrades. Don't be pennywise pound foolish.

You writeup sound suspicious. Prove me wrong

There's nothing suspicious about my writeup. I have people that have patronised me on nairaland. Bosses like @fruqy @aterejnr @weirdoo @kozmorgan can all testify that I deliver.

I have patronised him 9 different times.

Don't you think anyOne of us can have such writeUp like you did above ?

If you want people to believe you, the contact details you shared in here ought be on fouani's website. That way, people know YES this person is one way or the other affiliated with fouani

I am not a top level staff. So, the company can't include my contact on the website. You can go through my moniker's history. I've been doing business on nairaland for a while. No single issue since I started business here.

Contact @opistorincos

Are there any noteworthy sellers of the charge controller and solar panels around in naija? Would love to know prices of each compo,

My current phone uses a 90W charger though I mostly charge with my 65W GaN charger. But generally except most of the phones being charged are budget devices then 15 to 18W Cuts it anything above budget is from 22.5W and above. Even my current power bank uses an input of 33W.

I bought one from him last month.

Most times, we staturate the thread with so much noisy argument so much the OP gets so confused and lost than they were before asking that question.

HawkTuahGirl:

I've patronized him a couple of times, and he delivered without any issues.

So greenlight from me

Kindly do understand I got nothing against you as a person BUT anyOne can claim anything online.

A company that really want their products moved through an avenue should ensure there are ways for people to recognise their authorized marketers. Make e no reach tomorrow now, if and when kaSaLa burst, dem go come deny knowledge of said person.

Nothing stop anyOne, including mua copying and sweetening your writeUp and end up either making away with people's money OR riding on the TRUST people have for Fouani to push low quality items.

Either way, Hope you earn enough peoples' TRUST such verification is overlooked.

It's always a great experience with Opistorincos. I've used his services before and he never lets me down. If you need someone dependable, he's the right person to talk to.

Fouani has a website where we can buy directly, why buy from you. You spelt even fouani wrong and you work there. Good luck in scamming business, I doubt anyone here will fall for it.

HawkTuahGirl:

He’s Legit

Even all these legit monikers coming to this thread is already a red flag. You don't need to stress your self since you are in Kwara, your state people will buy from you and you been active on this thread will make people know you.
