My brother mecury

Noted bro, am still learning "RE" sorry for the numerous questions oh!

gadgetplanetng:
Series and parallel connection

4 batteries in series (voltage adds up) 48v 200AH

Make 3 rows of that then connect all in parallel (current adds up) so 48v 600ah

Gracias nwanne m nwoke, well understood

samnaija:
The question that is rattling everyone is why?.
Why would you derate your batteries such. What exactly do you want to achieve.
I did not get it then, that is why asked whether he has a pure water factory to supply light to at night.

The truth is no sane would do it regularly, whether lithium or lead. I keep saying it and I am glad people are speaking. Batteries are just storage units with a shelf life, in renewable energy the goal is to maximize the use of the shelf life (cycle) as long has possible.

Then this behavior we are seeing lately on the thread about lithium and lead is sickening.

How many times has it been said on this forum lithium is superior to lead in chemistry !!!.

To prove points you paint sceneros that you can't practice regularly, and you know a lot people make their decisions entering renewable energy from this forum.

We are all learning, we should all put brakes on all this absurd sceneros and remind newbies on best practices for longevity.

12pcs 12v 200ah batteries in a 4s3p configuration makes 48v 600ah battery bank

I don't really understand how this works and how 12 pieces 200ah will amount to 600ah.

Maybe using A * B methodology would help.

Can you please elaborate on it?

samnaija:
I wrote it up there 48v 600ah. How did you get your calculations (150ah *4).?

Tubular batteries.

I have 3 arrays each is maxed out 4200 watts.

Which brand of Tubular do you use?

samnaija:
You seem to like this LA and lithium talk.
The message is for new entrants into renewable energy.
You just stated your size of bank again, that is why you can confidentiality use all your appliances. Someone said you can get away using heavy load regular,with a smaller lithium bank, how? and why?.

Battery chemistry either lithium or lead has a shelf life or number of cycles before they pack up. If you have a large load on a small bank no time soon you go change naira to dollar.

And by the way I take more than 100 amps from my lead on good sunny day, my battery will sit comfortablly at 55v. While All the chores in the house being done.
My bank is a mere 48v 600ah,but my panel arrays do their job diligently

Hello bro,

1. Is you battery 150Ah * 4?

2. Which model of battery do you use, like Luminous, Trojan, Rita etc?

3. What's your solar array?

4. At what rate do you put/pull @C10 or @C20?

oldienavie:
It is because of people like kiekie that God created people like samir101ng .
Imagine the level of audacity and greed.

This same guy does not add any thing to the group in terms of support, he only comes in to extort innocent people looking to move to solar, taking advantage of their ignorance.

The painful thing is that he is a Pastor , imaging making 1 million naira on something that sells for less than 3 million naira, what kind of greed is that ?

May God forgive me for typing this, but this days it's more encourage to do business with native doctors than doing business with so call religious men of God. If you want to make heaven run from them, else if you see what they are doing in secret you will be tempted to want to mimic them, so Jesus should be the standard and not titled men called pastors, bishops etc.

Valto:
non is good ẹnough, only felicity is manageable, but likely not real capacity..

Thanks bro, I will stick with Auxano as earlier suggested. Besides they stc (Standard Test Conditions) are good enough and output equivalent capacity and even more 7W on the 300W panel.

Note: I contacted auxano solar directly and they 300W mono panel sells for 75k, while 250W mono is 65k. I believe this price is fair enough!

Juror:
Don't touch Rubitec panels. DON'T

Noted thanks

olopan:
1-3 is suspicious

They don't reflect the new market price, except the seller had old stock and using church mind of not making profit, else keep searching

Thanks

Valto:
some in that lineup are low quality and still not real capacity. i rather choose Auxano produced in Lagos,Nigeria, than the rest.

It's noted bro, thanks!

Can you also help state other more two from the 5 panels listed above that can compare with Auxano?

Please guys which among the below 300W Solar Panel can Max out close to it Wattage and that can also perform well even in this endless raining season?

Auxano
Felicity
Flame
SunPower
Rubitech

Kindly help arrange the above panels base on the one that performs optimally on a scale of 1 - 5

WCUB3:
Seen. Appreciate the response but the 12v inverters you mentioned above don't have inbuilt Charge controllers, they are stand alone inverters.

Why do you still need inverter with inbuilt CC when you intend purchasing standalone CC?

WCUB3:
Good evening bosses.
1. Please does anyone know if there are any quality inverter 1.5-2kva capacity that is 12v and has inbuilt Charge Controller. Those I have seen are 24v.

2. If I later decide to get a standalone Charge Controller can I still pair it with an hybrid inverter that already has an inbuilt one?

Thank you in anticipation of your responses

1: 1.5KVA 12v Inverters
KARTEL XD-W 1.5KVA/12V
ICELLPOWER - 1.5KVA/12V Inverter
Suoer 1500w 12v 220v Solar Inverter

2: Yes, you can. I have asked this question on page 1228 below:

padolife:
Hi y’all,

I want to warn members and the general public from buying from energymall.ng especially solar panels.
[img][/img]
I bought 4 units of 350w solar panels at 77,000 each for a total of N308,000. They showed me the original Felicity panel as sample and then shipped me fake 180w panels. I hope those panels are up to 180 sef.

Find picture of said fake panel nameplate below. All effort to reach them after has proven abortive.

It’s difficult doing business in Nigeria if people are looking to rip you off at any chance that they get. If only someone had posted their experience online, I wouldn’t have fallen victim.

Please do not buy from energymall.ng they will scam you

Sorry for the nasty experience bro, this is the more reason EXPERTS here needs to help newbies by listing fake sites not to patronize.

Just imagine the number of clients they will loose due to this act. People always forget about tomorrow, but the internet don't!

samnaija:
4 and 5 highly suspicious.....

Thanks, does it mean 145,000 is too small for 150Ah Luminous Wet Cell (i.e Solar Battery) or it's too much, please which of them?

samnaija:
He has a very valid point. A lot new entrants into renewable energy make a lot of mistakes by buying this useless batteries because it is cheap. Someone would have given them a quote for a solid battery,but price will make them opt for these cheap batteries mostly
Gel.
If the marketer is giving you a 12v 200ah for 80k. Run for your life, these are fall back batteries that marketers give customer when you reject their original battery quote .

Due diligence is required.

Please guys which of the below product do you think is suspicious considering the prices?

1. Luminous Tubular Battery - 150AH/12V = 90,000

2. PROMO OFFER: Luminous 220ah/12v Tubular Battery = 105,000.00

3. Luminous 220ah/12v Tubular Battery = 127,000

Note: This is same product from same seller in no (2) above

4. BATTERY 150AH/12V WET CELL LUMINOUS = 142,500

5. Luminous Wet Cell Tubular Battery-150AH/12V = 145,000.00

NiyiOmoIyunade:
It may be easier and less error prone to do this calculations at the single battery level.

So each 12v 150Ah battery holds about 1,800Wh and the max discharge at C10 is 180w per battery while at C20 is 90w per battery.

I do not believe any of these basic lead acid batteries can indeed sustain C10 discharge and maintain the cycle life so you are better off with;

A conservative C20 discharge of max 180w-200w for your two batteries to give them a chance to live very long or an aggressive C10 discharge of 360w-400w for the two batteries if you don't care too much to max out the life.

If you incorporate solar and your system properly sized, you may have headroom to run larger loads during the day directly off solar without depleting the battery.

You are very correct, I have done some extensive research lately in respect to luminous tubular batteries. Even the NRGT & ILTR EX models are Rated @C20, but this LPTT is indeed C10.

I went to the extent of contacting some sellers online, but claimed NRGT is C10 until I asked her to show me where I can confirm that, she read and refused to respond so I suspected she wasn't honest and I had to dig deep.

Once again thanks for the enlightenment!

netotse:
Yes, instead of connecting the solar panels to the inverter you will connect them to the charge controller input and connect the controller output to your batteries. (this is in addition to the battery-inverter connection)


You can, it's just that if your panels ever generate more than 1000W it will ignore the extra 200W. given that panels rarely achieve nameplate I would say go ahead with this.


Non hybrid inverters don't have inbuilt charge controllers so cannot chare via solar, they can charge via NEPA and generator(hopefully your gen is big enough)


Yes they can

Thanks for the response, I appreciate.

What if charge controller is attached, can it charge batteries via the three methods?

TechGeek777:
Luminous 1500VA/24V Solar Hybrid Inverter

Key Features (1 - 4):
1. It has 40amp inbuilt charge controller.

Can external 60Amp MPPT Charge Controller be integrated with this inverter?


2. Up to 1000 Watt PV Module solar panel compatibility.

Does it mean that one cannot attach (4) * 300W Panels?


3. The batteries can be charged by both the Grid/Generator and true solar power when the Solar Panels are connected.

Can Non-Hybrid Inverter like *Luminous Optimus 1600VA/24V* charge batteries via Gen, NEPA & Solar Panels respectively?


4. It can also deliver power simultaneously while charging.

Can Non-Hybrid Inverter like *Luminous Optimus 1600VA/24V* also deliver power while charging?


Please expect in the house respond to these questions thanks.

@NiyiOmoIyunade

Please oh, I need answers to these na abeg I dey oh

Ferdiwar:
Good morning all,
Please I am planning to go green and need your input on which is a better option between flooded and AGM/SMF batteries as I plan on getting it.

With the proper maintenance (battery rotation, equalization, etc) which amongst the 2 will last longer (I can't currently afford to get a new 24v lithium bank).

Proposed set up.
1. 1.5kva 24v luminous hybrid inverter
2. 4x 350W panels
3. 60A Techfine or Powmr MPPT CC
4. 24V 200AH to 305AH battery bank.

Any other other advice will be very much appreciated

Thank you

Sent as requested.

Received, thanks!

FEGEITOK:
My initial post before changing to the one that I finally posted was to request that you

Add an email to your nairaland signature and I will give you all the information to help you bring down the cost.

I am willing to share the information, but if even venture capitalists (non-Nigerians) say that there is information that they can willing to put online and information that they would only share in person you have to understand that I am not trying to hide anything from you, my concern is with the method of passing on the information.

Anyone who attended the talk "How to apply and succeed at Y Combinator" which was delivered by Dalton Caldwell, YC Partner and Head of Admissions on Monday 8 August 2022 at 12 GMT-4 will appreciate where I am coming from and where I am going to.

If you decide to share it online after I share it with you privately, it is entirely up to you.

FEGEITOK:
Can you do a google for authorized distributors of whatever brand of battery you wish to buy?

The same goes for the inverter.

Next, find out the minimum order quantity to qualify for wholesale pricing. If you can buy that quantity yourself, you got yourself a bargain, if you can arrange a group to buy the same thing.

It is not my intention to destroy livelihoods by sharing the name of the distributor for the kind of inverter and battery that I am using.

You know very well that some people advertise those stuff here. It is not my aim to put them out of business.

Okay thanks, I understand the angle you are coming from.

NiyiOmoIyunade:

If you incorporate solar and your system properly sized, you may have headroom to run larger loads during the day directly off solar without depleting the battery.

Thanks it's noted, I will abide by the rules. I appreciate you and earthrealm for the massive enlightenment.

FEGEITOK:
Comments like this, made me spend so much time researching before buying my initial batteries and inverters

The research paid off, I was able to get the batteries and inverters at a wholesale rate!

So please do your research, you might even save money by doing so!

Please where did you get both at wholesale price?

earthrealm:
1. Try not to load your setup above 24v x 15amps, thats about 400watts, after sundown or when you phcn isnt on. However you can get away with not following this religiously if you go above this recommendation by upto 20 to 40%....as long as you do it intermittently and not too frequently. Eg you can use a 600w pressing iron to iron ur clothes since the heating element goes off and on.

2. The batteries are in series, so the c/10 cuts across the 2.
18amps is just a lil above c/10, so you are good.
If the batteries were in parallel for a 12v setup, then you would be needing above 30amps to keep the batteries happy.

Thanks for this reply, it's informative and I really do appreciate it.

Oshomo12:
This may be a bit complicated, but let me list some, not in order of performance.
Trina, Jinko, Ja, Risen, Canadian, Lg, Yingli etc

Complicated: you may be offered the above, but are they original? You must get someone that will offer you the original brands o, AT A COST. They do not come cheap.
Any solar panel you see or hear about, just search for its presence online, they should have a site(not jiji, nairaland, or any other selling sites) that will tell you about their products.

SO MANY USELESS SOLAR PANELS ARE HERE NOW! They advertise them on this thread also, many of them. Be very careful fa.

Thanks bro, I saw 340W Jinko at 68,000 from this site
https://www.solarkobo.com/product-page/jinko-solar-340w-monocrystalline-panel

Also, I saw 4 X 24V/300 Watts Monocrystalline Solar Panels - 1200 Watts at 269,500 from Konga


Which do you think is original?
What's the price range for Jinko and Canadian Panels respectively?
What's your take on Flame & Felicity Panels?

Please am trying to get the best at a moderate price!

TechGeek777:
Q1: Since I will be using (2) * 150ah, on C10 tubular capacity at 24v setup, which of the below example LOAD should I follow per hour?

Formular used:
Battery Amp / C Rating * No of Battery * Volt

Example 1:
150ah / 10c * 2batteries * 12v = 360W

Example 2:
150ah / 10c * 2batteries * 22v = 720W

Please which of the load per hour should I use at Max?



Q2: Luminous Optimus 1600VA/24V has max (18amp), will this be sufficient to charge (2) * 150ah @ 50% DOD?

Please I need answer to this oh, na abeg I dey
