wouldn't advise that you play with li-ion cells unless you know what you are doing, it is also a labour intensive task to couple 300+ cells. This was the one I built about 3 years ago, 3s 250ah and 7s 120ah

Boss come and teach me work.
Do I pm you

Valto didn't do anything ooo. The guy was afraid initially to deal with valto, due to his past experience with one mumu in Ibadan.

Hello everyone,

I had an installer complete a 2.5KVA solar at my home. However, a piece of the battery cap broke and has been crusting leading to at least 1 episode of power outage. I fear that this would recur and of course, the installer is MIA, lots of excuses and stories. I am trying to fix this and a picture is attached, kindly advise.

Where can I buy the cap and is it a DIY replacement or do I have a bigger challenge?

Installation is less than 6 months old by the way. That's one heck of an installer for you.

What is your questions?

I no understand.

Is the terminal i broken and you want to replace it?

155w @6hrs on low budget

500 watts sachet inverter 25k

100ah battery 150k

30a solar charger controller 10k

2 150 watts solar panel 90k
and other minor accessory 30k
find an engineer to install it for you and you are good to go.
NB you can go for tokunbo panel to reduce cost.

This is almost 400k .

The max back he will get is 3hrs. From this set up.

VonScott:
Evening bro, what solar solution would you recommed/adopt for a BQ or one bedroom in todays current dispensation (economy wise and market availability)?

hp notebook - 45W
akt lightbulb - 2 nos @ 5W
smartphone charging - 2 nos @ 10W
ox fan - 80W

total load: 155W
Also, laptop & led bulb takes most priority and needs to be able to last at least about 6hrs at night.

Economy no wise this period .
But if you want to go cheap, lithium power kit would have been a very good option for you if you had a DC fan.

But considering your current load
Just budget 600k up

I need a solar installer in Benin city.
Somebody please recommend someone that is good for me, please. 🙏🏼

If you don't mind I can come over.
I reside in warri

obinna37:
Pls house, some one want to buy 420w solar panel,he is considering between bifacial and monofacial which is better,I have tested the two, bifacial is reading high in voltage and current

It depends on the mounting platform

Trippledots:
SA

Please give us price update
We are low key following

noblechoco:
Exactly
Before they grow old and become something else

You no Dey package them well.

I saw one rich man ekuke Omo I love ekuke once.

The thing is Na meat eyes we dey always use look ekuke

swagifted:
Meanwhile I am in the market looking for this hybrid Air condition split units... The one you can connect the solar panel direct to the outdoor unit... Deye has it on thier website, but all the deye dealers i have reached out to don't have it in stock...

If you find it update us please am following

Dam5reey1:
It's like saying Apple Authorized store selling clones or Slot selling clones..

It's not our of place for some sort of shenanigans to happen.

The thing is how do we verify that they have been authorised?

Even after authorisation (for professions that require licensing) I can still provide sales/services even without my renewal.

Hope you understand where am driving at

Dam5reey1:
Right source, simple!

What if right source is supplying clones and inflating price?

Way back Jinko 250-300w series, there use to be imprints of Jinko solar embedded in the panels surface.

This new ones no dey get am oh.

I don't mean to cause distress but is there any case for alarm

Trippledots:
Measured voltage and current with a clampmetre at constant load. Both AC side and then DC side.

Okay thank you boss

dollarnaira:
With the right mosfets replaced,it will work

No be MOSFET be the problem.

It's beyond it

Trippledots:
So I did a test today with a victron quattro and got about 61% efficiency. I've done this before though and had to repeat it to be sure I was not making mistakes.

This confirmation led me to do some research and I found this....see pix attached.

In summary,these "cheap chinese knockoffs" as some people like to refer to sachet inverters, are not bad at conversion efficiency, and basic protections.

How did you do the test?

Wonder1844:
My Charge controller with this error display
The product is Felicity 120A charge controller.
I have disconnected the battery it still shows the same.
What's the possible solution please

E4 mean battery voltage is high
Does it charge at all?

EduTechTainMent:
Suoer 2000w/12v sachet inverter

It's gone.
To get the SMD ics and all that stuff is not worth the stress.
It's even cheaper to replace it

oloet:
Smoother and well optimised environment over the windows system.

Na so them take dey chop our money 😭😭

EduTechTainMent:
Similar happened to me when my installer attempted my installation, although mine was a case of over voltage from battery to inverter. He connected the batteries in series and used my 12v inverter. The inverter just blow. Until now I no see am repair. It has been with different technicians for the past 6 months and none has been able to repair it. I just counted my losses and moved on. It's now scrap as far as I am concerned.

What type of inverter is that

Please I need help on this.

Since you plan using lithium battery, buy hybrid inverter 3.5kva 24v.

That's what is readily available in the market.
@valto get for sale.
You didn't include the time you want to run it.
So I can't provide any opinion on it

adibo:
Also, I am caught in two minds, between buying a 2.4kva 24v mercury hybrid inverter and buying a 1.5kva 12v Mercury hybrid inverter. I need it for lights, charging of laptops and phones, 120w fridge, 240w washing machine and 32 inch smart TV. I heard that 24v inverters are more efficient than 12v inverters. Also, I am just considering buying the 2.4kva in order to have extra space for more load in future. What is your advice?

24v is your guy then

I bring you good tidings .
I have access to supplying you the below tubular battery at very good rates (255k) in Lagos.

Batteries comes with 18Months warranty.

Please can you teach me solar installation.

I have responded to your email already.

But that's by the way, where are you located?

Prices have been reduced by fouani for jinko panels.
Incase anyone needs😁

What's the current price

Light78:
Here

I still know book.

I was trying to get that relationship..
Thanks for doing throwback

adibo:
Thanks for your response. You mean that I will need more solar panels to charge them, right? Will four 440w solar panels be able to charge the four 150ah batteries?

Yes to charge it.
To run load and charge, no it's small

I think the answer should be 4 and 8 respectively

adibo:
Good morning, I want to get batteries for a 2.5kva or 1.5kva hybrid inverter. I just noticed that two 220ah batteries give a total of 440ah at 594k while four 150ah batteries gives a total of 600ah at 580k. By my local man logic, the 150ah option seems better to me cus I get about 160ah more battery capacity. Pls, those who are experts, is this my logic correct and can I go for this 150ah option?

In actual sense, the 150ah is a better option considering that battery life span will be higher.
however, there is an overhead cost in getting solar panels/means to charge them effectively.
