Good afternoon my oga I am planning to publish on Ingramspark, please do you have isbn to sell , so I can buy and publish there

if you truly want Ingramspark please get isbn from bowker . That's the best

You can search bowker in Google

OkoroPeugeot:


Ol thought Toris was a brand.
Was not on google

no its not

OkoroPeugeot:


Which one is toris?

my brother, battery get different types. Ask the sellers. Use this POst to do your research.

yomifowe:
I have tried fivrr and freelancer website for some time, I even have accounts with them but I was never given jobs to do. That was why I gave up on them. I doubted their authenticity. Or what do you have to say about them.

those things work. But due to Uncle competition, you have to advertise first to see any traction.

Especially Fiverr. Use your head. You can use Facebook ads, Google ads or Reddit . When they find you then repeated customers means you are in. If you have any challenge, nairaland can be a good place for honest people. I did many free things on nairaland before getting paid customers.

So we need as much panels if we are adding many battery.

Sometimes, the power is inverted from panels. Especially during the day.

This works only in the day time.
You won't have light at night.


You need power from battery to have light at night when there's no sun.

When you are going to need much panels.

Yes there's a time we should install Many panels.

1. When you are powering a house or office.

Without using battery. Much panels is needed.
And the power is inverted directly .

2. When you add more battery to the setup.

So pick a battery system you prefer. Remember that we have grade abc in every set .

I will be using 18650 battery for my laptop power pack.

U can use car battery but they are heavy for me.

More updates soon

jamace:
Thanks for the lecture. Good knowledge.

you are welcome

Good day

By the way, get a multimeter ready always. Test everything to make sure it's ok. Don't underate that little device.

Any questions?

Calculating your power consumption

Formula = power is equal to current x voltage.

P= IV

Always use this formula.

P is watts

I is Ampere

V is voltage.

P= IV

Every battery you buy has voltage that is our V.

current is our I some battery like car battery is
12v 100A.

Deep cycle battery can be 12v 20a, or 12v 40a.


Lithium ion or what I call laptop battery is 4.2v 2.2a each.

You then connect batteries in series or parallel.

For example, adding 12volts + 12volts = 24 volts.

That's series connection.


But 12v 100a battery + 12v 100a battery in parallel will be 12v 200a.

So series connection increase voltage.
Parallel connection increase current.

Went to get some wires recently. As I was about paying, I remember that the wire needs to be colored red and black which means
Red= +ve
Black = -ve

I withdrew becos the said wire carried red and orange. That's enof confusion there.

Get wires that carries these insulation color.

You will save your self and your house much money.

Solar connection does not give electric shock but if it burns your electronic, you will fear.

Knowing which is live wire and neutral is good.
I look at the colors and match.

Solar no dey forgive miswiring .

A word is enof

mrsage:
This is good

thank you. Just contributing the little I know.

ManOfCompetence:

Good morning, I just stumbled upon this thread and have read through from page 1...
I'll like to get started but really don't know how to write, can you mentor me so as to get started please

I've watched YouTube videos and did some paid WhatsApp classes, but I'm still having this "writer's block"

send me a message

skywalker240:

sir, i aam interesred in this kdp and freelance, i already sent a pm

already replied.

So I ordered for some things I need.

Will drop the links here.

Electrical components are quite cheap from alieexpress.

i bought the following
1. a BMS BOARD FOR LAPTOP CELLS

We have 3s bms 12v
6s bms 24v
4s bms 16.8v

BATTERY MANAGEMENT *BMS* SYSTEM HERE

you can START HERE over at alieexpress to find them


i also bought this digital scale
see the digital scale

Anyone interested in getting helium 10 cost 97$ monthly.

Looking for someone to split payment

SweetOnugbo:
I'm having difficulty verifying my payoneer account.
I don't have a voters card. Can I use the temporal slip with the nin to verify it??

Please this is urgent. Thanks in advance.

they do reject NIN. Try drivers license

And normal nepa wire that has red and black.

For battery to house wiring.

Please use wires that has color red as positive and blue or black as negative.

I have burnt something due to wrong connection. Don't buy wires without these colors.

I use this wire for panels to controller.

How do you prevent overcharging?

Check your panel connection. Most of our naija tech guys for solar quote panel sizes just for the money.

My brother, if you install 5 kilowatts solar.

You can safely charge it with 250 watts panel.

I know it seems small but it's will do. But many tech will tell you to install 2-3 kilowatts panel.

That's overcharging loading.

Another thing is that

Panel wires should NOT carry too much current.
Battery wire to your equipment should be done correctly. Use normal Ac 220v wire if possible.
The whole house wire should be good. Because solar sometimes pass current and if your wire is strong no problem.

Let me pause here...

I wanted to make this explanation as simple as possible.

When you are boiling water, after you're done, check your heat source. It's likely warm or hot.

This happens because you have probably used the stove or gas for long.

Now even your gas cylinder can explode.

Why? A number of reasons.

But can you use gas safely for years ? Yes.

Can you use your stove safely for years? Yes.

That's how these battery are.

Lithium explosion depends on overcharging, thickness of wire used , and the owners knowledge.

What causes this explosion?
1. When it's overcharged
2. When it's overheated.

Now how is it possible?

When you get excess panel watts. You are suppose to calculate your needs in solar panel for charging. Will explain soon

SilentVboy:
Nice job @op. I would prefer the deep cycle battery.
Since I witness how the lithium battery exploded in an inverter that a guy bought from Lagos to power his phone, laptop and bulb, I began to hate it. The fire even burnt part of his legs. The lithium battery really don't like heat.

yes. every day i learn about lithium, the safety precaution is to avoid explosion.

Tips when getting a good battery

1. For car battery ask the mechanic. They know the best.

2. For deep cycle, get used toris. Especially from Lagos. Around 50-55k should do.

Beware of so many China battery and new ones.

3. For laptop battery. Get brand names like Panasonic, Samsung, LG. And sanyo.

Used laptop battery is like okrika, you need to select them. Samsung has many types but they are generally good. Same with other brands. Here is a pic of the popular one attached.

None of them is cheap.

So ask around for pricing.

Before you start.

Recap!

What determined the type of battery you buy is
1. Money
2. Usage
3. Knowledge and durability.

Deep cycle battery is better than car battery.
Lithium ion is better than both.

Which battery should I buy?

It depends on where you are, how much you have and what you want to power.


For example. If all you want to power is a laptop, then choose the easiest battery you can get .


If you want to power your shop or house, deep cycle will do.

But if you need the best of both worlds, then lithium ion will do .

Each has advantage and disadvantage. But lithium is good if you are willing to pay for it.

Otherwise, deep cycle is your next choice.

For me , I use laptop battery . Which I get from the market.
