In small capacity say under 6 batteries, I see nothing wrong too. But if you really need energy to require up to 20, that's where I'll recommend going lithium. I've seen cases of this type of system dying way before their time due to issue mostly related to charging. Most of these large banks like this miss out on proper charging. Going the lithium route would've been a better alternative when you need energy this huge.

Boss, even with large bank, lead acid battery can still be properly charged and managed very well.
Once you get the basic things right, every other thing takes care of itself.
This issue of comparing LA battery with the Lfp has been discussed extensively some years back in this forum.
George_D has large LA battery bank and he has used it for about 6 years then. Maybe, it's up to 10 years now.
He's one of the founder of this forum and I really learned from his knowledge and I'll always appreciate him.

You spoke well . I don't know why some people are hell bent or having sleepness night over lead acid.

The truth it is cheaper and serves its purpose. I have been using tubular batteries for 4years plus and no issues. Majority of people are on tubular for one reason it is affordable and carries its weight.

You go to an average Nigerian home it is lead acid, it serves its purpose especially in this difficult times. Am sure I will keep running my tubular till a different technology apart from lithium comes along. (Likely get another 5 to 6 years from those bad ass batteries).

Likely then, i will jump on that one, then those that are currently on lithium i will castigate them also . And ask the question wetin you still they do with lithium....... technology has phases .

There will be no need to castigate anyone because some of those guys using lithium phosphate today may get there before you..
As I earlier said, everything in life has to do with choice.
It's wrong to condemn people's choice.... What works for Mr A may not work for Mr B.
Whenever I designed systems for my customers, I gave them the two battery chemistry to make a choice, even though I'm not selling lead acid batteries.
There are some lead acid batteries (12v 200ah/220ah) that are currently sold within the range of 300k to 310k and they will serve the purpose at a given period.
There are also lithium phosphates of the same capacity and the same amount and they will serve the purpose at a given period as well.
It's all about the market flexibility, the individual budget and what they aim to achieve.

Honestly, I keep asking myself this same question "why do people still buy tubular"? I saw a new project some days ago, the tech guy arranged about 20 tubular batteries for the client. I just shake my head and pass

There is nothing wrong tubular batteries. I've a friend who has used his for 5 years now and they are still waxing strong. He bought them from the right source and he's baby sitting them as well as derating the capacity he's using...
Some people love buying products they're familiar with while some like going for new innovation....
It's a matter of choice.

lol, if its in a good hotel you can get your money back very quick....

What do you mean by good hotel?
What will stop me from getting the return of my investment in bad hotel?

Boss, you want set me up abi?

I fit try help small shall.

Kindly tell me these params:

How many individuals will be using your service(Energy)?

How many KWh will they require per hour at least?

What's your total Energy supply capability?

6 people.
500w max during the day and 300w max at night.

Oga TechGeek777,
Please come and do this business analysis for us.
If 9m is used for the installation, how long will It take us to get our money back at the selling rate of #200 per kWh?

swagifted:
it depends, my friend has a private student hostel in Uyo, generator is banned, he installed solar and installed prepaid meter in every room...When we last spoke he was selling at about 200 naira per kwh.. And you can't draw more than 150 watts at once,the guy no de ever get vacant room..... But at the moment, i am discussing with another company to come and do the same for me in UNN nsukka for a private student hostel, meanwhile the same company have given me there rate, its 100 naira from 8am to 4pm (when its sunny), and 158 naira from 4pm to 8am the next day.

I was equally working on the cost of installation, considering the high cost of materials and how long it would take to get back the invested cash.
Many of us are looking for short term business.

swagifted:
but wait, is it because of the low voltage that happened days back?

What type of prepaid meter is he using?
For power draw limit, I guess he's allocating current limiter switch to each room.

Gentlemen, whats the best 24V High PV Hybrid in the market right now in your view?

Go for Victron, Deye or Growatt

FEGEITOK:
Which area is that? Shelter Afrique? Ewet Housing?

Kindly share. But for the rest of the State, it was a very terrible experience.

Got family in Uyo so I speak from the experience of living there when I visit.

I would love to build a vacation home there, hence the question.

FEGEITOK:
Interesting idea.

BUT

150 watts is too small. It should be a minimum of 1000 watts per room.

As a person who visits Akwa Ibom frequently, I understand just how poor the power situation there is. As limited as the power he delivers is, he is a godsend to those students.

I knew how frustrating it was to be a student without electricity and I had up to 2 generators at a point, and to guarantee constant light, I sometimes never stopped the gen even to refuel (as risky as that was I will admit). I recall how after the generator would run non-stop between 3 and 5 days the sound would change, then I would have to put it off so it could rest to continue the battle later.

Thanks for sharing.

Boss, the lack of electricity issue is everywhere.
There is an area in Aks that has nepa light 24 hours with special tariff and that is the area people buy ice blocks from.

AllyPolly:
Hello sirs,
Please which would you advise to buy between a Pylontech UP5000 4.8kwh and Felicity 10kwh LiFePO4 battery?
Or is there a better alternative within the 2-2.6m price range?

Pylontec battery is more superior than lifepo4 battery, hence the price difference.
If the Felicity can give you quality lifepo4 battery with real capacity that can take you for 10 years, I would suggest you go for lifepo4 that has more usable capacity.
REASON: In the next 8 to 10 years, another battery may likely come out that would be superior than these two and you may likely want to switch over...... If you were to compare pylontec 4.8kwh with lifepo4 7kwh at the same price, I would chosen pylontec.
SUBMISSION:Human wants are unsatiable.

What is your battery size?

It will be strange to get a 48v 1.5kw hybrid inverter

Very hard to find such in Naija.
Two months ago, I was searching everywhere for 12v 2.5kva to 3kva hybrid inverter and I couldn't find it. At last, I bought it from China.

easyyoke:
432watt cannot significantly increase your electricity bill as compared to using an A.C. Let me teach you how to calculate your electricity bill.
When you consume 1 unit of electricity, it means you have consumed 1kwh.

If you use 432watt in 1hour, you consumed 432wh. If you convert 432wh to kwh, it will be 0.432kwh. So if you charge your system for say, 5hours, that is 432watt x 5 = 2160wh. If you convert it to kWh, that is 2.16kwh. Meaning if you charge your battery with 432watt for 5hours daily, you have consumed 2.1unit of PHCN electricity.

Now in sharp contrast, lets look at an A.C. Those are quite power consuming. An average 1.5HP AC consumes about 1125w. And there are ACs that are even bigger than that. But lets just use 1.5HP. So if 1.5HP consumes 1125w, it means in 1hour, you have consumed 1.12kwh. Lets assume you put on your AC for 10hours a day. That is 1125w x 10hr= 11250wh. If we convert it to kwh, thar is 11.25kwh. So that means if you put on a 1.5HP AC for 10hours, it will consume 11units😅. And I simply limited it to 10hours. Some people run their AC much longer than that.
So you see that your 432w for charging your battery for 5hours only consumes about 2unit and that is quite small in comparison to 11units that a 1.5Hp AC will consume in 10hours.

Hope this explanation helps.

This analysis is applicable to those who want to freeze their rooms with 16°C temperature.
My parlor AC is 1.5hp consumed 1.2kw and I used it mostly during the day at 20°C.
My room AC is 1hp consumed 1kw and I used it mostly at night with the temperature range of 26°C to 28°C consuming 500w max and I still woke up to see 50 60% of my battery left.
We know how to manage RE.

dollarnaira:
Baba it is about choice. As for me, I detest hybrid for now. Repairs, complexity, inbuilt cc can be pwm , if one part get damaged it means the whole system need to be admitted by a technician. How long it will take for repairs? Only the gods can tell. If you make use of lead acid and is taking too long to fix, sulphation will gradually set it. With non hybrids you can have different spares. Use your head sha.

It's still a matter of choice as some people may consider other factors like price, idle power consumption.....

Goodmorning house

Please need advise
I want to purchase inverter and solar panel
This are appliances I want to carry
Fridge
1 Ac (inverter)
4 fans (regular ones not industrial)
2 tv
Sockets
Light
Which will be regulated


I was told to get 5kva hybrid inverter, 2 tubular batteries , and 6 (300watts) solar panel

Please need suggestions on best to use as I’m on a budget and don’t want to spend more that 1.2mill
Also is hybrid inverters with inbuilt mppt controller better that normal pure sine and separate mppt controller ?

The answer to the last paragraph is NO

Valto:
sorry 1.2m can't do it. u want to run an inverter AC and 4fans,fridge, 2 tv, lights, u also made mention of needing a 5kw inverter.

48v Hybrid inverter atleast 500 to 600k
4pcs of tubular batteries atleast 380k each=1.520k
6pcs of 550w panels =720k

I may not know the type of 550w pv at 120k and whether it would produce up to 80% of its rated capacity...... He could only many the stated loads during the day and the tubular batteries sagging would not permit the AC and the other loads to run for long time.

princely009:
Ok.. thanks. Spoke to Valto earlier today and we've made some arrangements.

That is good

Cant find your contact details on your profile

Zero8zeronine5six7four2six2.
The coupled 302ah 48v has been bought.

Please, I need this urgently before price shoot up again please.....

NOTE: a not always at home during the day from Monday to Saturday, (inverter will be put on when in the night, probably 200w load till 11 pm and 80w with a century rechargeable fan which will only be connected to mains when notice is low), while on Sundays my total can never exceed 360w, hardly will it reach dt self,

A 43 inch lg smart tv 65w

Xboom 720 W RMS 80w

Probably a scanfrost freezer 150w,we are not a fan of cold tins

A small nexus standing fan 65w (sitting room)

And occasionally, 26 inches ox standing, if av visitor and crowded sitting room

Get the 48v 5,376kwh lithium battery from Valto and 3.5kva 48v Felicity hybrid inverter.
When you have fun, replace the ox fan with an energy saving fan. The performance will still be the same.
