Reading these several Lithium vs Tubular takes...

Sincerely, not everyone can afford Lithium at a go, but my worry is the way these Tubular now flood our market. It leaves something to be worried about.

If not exaggerating, there'll be over 200 different brands of these Tubulars available in Nigeria currently and that's where a lot would simply sink there hard earned money on thrash.

I also started with 2 pcs used Sealed Lead Acid battery few years back before I tried assembling a small Lithium battery for myself and currently see those LA batteries as simply waste of money.

So my honest opinion is people going for these Tubulars should reach for reputable brands to effectively enjoy their invested worth.

There's no how you can enjoy a used sealed lead acid battery cos you don't know how it was used, it might have only 20-30% efficiency left, to enjoy Lead acid you have to buy it brand New from reputable brand

Pls tell me one person with one tubular on freezer? We are all here to learn.

Start up of the freezer is roughly 700w to 900w oooo.

That it the annoying part 50% DOD
ROUGHLY dat is 110k for 330k. 105ah LifePO4 is 280k with 12yrs or more. Most of are being deceived by 220ah that is already fake.

I use my freezer on one AGM ba3 during the day when sun is up, do you use your 105ah on freezer at night? For how many hours?

nicodemusic:
Bro me sef dey reason am say I for get 3.5kva instead.. I got 5kva cos I thought it would give me more room for expansion without worrying about upgrading the inverter.. Only appliances I use it for are fridge (not sure of the fridge's wattage cos my daughter peeled off the sticker but it can't be more than 500w), 1hp polystar ac, 55" TV (not also sure of the wattage cos I can't take it off the wall to check but I'm sure it can't be 200w if at all), 2 standing fans and then some energy saving bulbs.. Note that I don't put on all these appliances at the same time. I've never exceeded 10% load of the inverter capacity.

Bro are you kidding me? You are the one killing your batteries and you are complaining, your loads are more than 1500w, only your Ac is more than 1000w, and with all this loads your ba3 won't charge and when the sun is down your ba3 is already down

dollarnaira:
You still didn't get the point.
See enh right now:
Today 26/3/24 12:05pm
115w freezer
50w tv
12w tv box
2 rechargeable fans
1 100w peddling for sewing

All working... On just 100ah LifePO4.

You cant try it with 220ah tubular.

N.B 3 days ago I plugged in 1250w hair dryer.
Try this on 220ah tubular e go pack up less than a year. THIS IS THE POINT!!!

Bro all you mentioned here are not up to 300w, a 220ah tubular can carry it comfortably and still maintain a 50% DD

isangjohnson:
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.

George_d one of the creators of the thread not the forum, take note

Why do guys buy tubular?

I would had rather buy 50ah LifePO4 or scrap lithium ion batteries from laptops than spend a kobo on tubular.

Tubular cost over 250k claiming 220ah ( deceitful) while 50ah cost 140k.

Are you saying a 50ah lithium ba3 will last more on same load more than 220 tubular ba3?

nicodemusic:
Thanks so much for your detailed analysis.. Bottom line is ; should get 2 more panels? .. Would 2 more panels of 400w or 300w in this case (making 6pcs connected in 2s3p) generate up to 4.8kw or more required to match the battery bank?

Also I noticed my batteries sometimes shows 26v (supposedly charged state) but it would not take a long time before it gets to about 23.5, the inverter alarm kicks off and then shuts down.. Does it mean it's just showing 26v but not charged and therefore not strong enough? My load is always below 10% so I guess the load is below 500watts (since inverter capacity is 5kva)..

I just want to be sure if it's more panels I need or if the battery is misbehaving.. Thanks

Bro why are you using 5kva on 2 batteries, you wan kill your batteries be that, and which appliances are you using?

dollarnaira:
Waste of money.
Better on 100ah lithium than 220ah x2 sef

What of original lead acid fullriver

nicodemusic:
I'm not sure if the panels are of of real capacity or not.. They're facing west mostly exposed to direct max sunlight from midday till dusk..

From the sticker you posted, the panel might be relabelled, your 400w might be 300w and it's better to contact a professional to mount your panels so you don't damage it or fry your Cc

nicodemusic:
Thanks for your input.. I eventually connected the 4pcs of 400w panels 2s2p and this image attached is the average result I get on a daily (2days monitoring).

Is this good enough or improvement is required to charge 2units of 12v 200ah.. Meanwhile I use a 5kva 24v inverter if that's necessary to know..

All inputs are highly appreciated

The wattage is not showing?

nicodemusic:
Please review this response of yours.. You only described 5panels @ the bolded.. What connection (parallel or series) would I use to attach the 6th panel?

I'm considering adding 2 more pcs of 400W panels to it if that's what it would take to have a good charge on a daily basis. So far, I haven't been satiefied with the results. I have 2 12v 200ah Quanta batteries.. I particularly went for quanta at a higher price because I learnt it was better. I'm worried because my neighbor's system stays way longer than mine.. I guess cos I just installed mine and perhaps it's not charged.. Note: Neighbor has 3.5kva 24v setup with 2 12v 200ah felicity battery, while I have 5kva 24v setup with 2 12v 200ah quanta battery. I want to max out my options to determine if the batteries are the culprit so that I can return them ASAP.. Thanks everyone

Your batteries are ok, the issue is your panel, are you sure they are of real capacity?

Secondly where is your panel facing?

Someone should explain to me why I can't add new lead acid battery to the one I'm currently using?

jonescosmos:
The picture has all the details. But since you asked.

PV is 15KWp (16x 600w Canadian Solar Panels. 10x 540w Felicity Solar Panels)
Inverter is Deye 8KW EU Model x2 in parallel
Battery is Felicity 15KW x4 in parallel though capacity test topped off at 13.5KW. So I have 54KW Battery literally.

You suppose Dy give your whole estate light

AVAILABLE:
48v 230ah for 2.379m
24v 100ah for 518k.
12v 280ah for 778k
12v 160ah for 445k

The 160ah is how many kWh?

earthrealm:
what u seek is almost impossible to find as a single unit...48v 1500w, minimum 48v i have seen is 3.2kw
only option is to buy separate 48v charger and satchet inverter 48v

It's not impossible, you can import it from china

dollarnaira:
Charging profile
Ask guys here.
But still why you guys buy tubular

What's the problem with tubular?

Gshems:
Mppt charge controller?

Yes

bassdow:
using solar panel of 200w and above on a 12-volts system doesn't really work well. it's OKAY managing it that way if you have plans adding more panels later.

Now that your charge controller na toy abeg. whenever buying a charge controller, e specially if it's PWM, always aim for anywhere 50amps and above.

Most of those PWM charge controllers are overrated, also when the sun comes out well and the solar panel starts generated more output, some would be tripping OFF & ON. You easily could tell that from the Solar Panel indicator on the charge controller.

Let's equally not forget solar panel positioning - we have no idea how and where it was mounted

Bro I'm using 2 310w panel on my 12v and it works well

isangjohnson:
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.

The guy don't need a 48v system for a 360w load and he's not always at home

Obnoxious2001:
As you are planning to buy hybrid, plan for a good protection systems (earthing in particular).
Repair of those equipment is expensive.

Small lighten strike, office will just open

Why is it that lighten don't spoil Cc it's only inverters they affect

dacool1:
Just be ready to replace your battery soon.

So many things could easily go wrong. Too much charging current on any day you decide to turn off your inverter, also You would most likely overdraw current at nights given the size of your inverter.

My first advice is you double the battery bank.
Secondly, a 60amps charger with a 24v system would have been better and probably cost same or just a little more than what you will be spending in total. Like smaller cable Guage, cheaper breaker etc.

Just keep in mind that whatsoever you have in mind will be different from what is achievable on renewable energy except you've got deep pockets

Plus I would have advised you got a lifepo4 battery, as it tolerates more abuse. Just make sure you turn off the system as soon as your battery voltage gets below 12.0v on small loads. The inverter you got is not optimal for lead acid as it won't cut off until battery voltage drops below 10.5v so you've got to really monitor your system

Why would he replace his battery soon when you don't know his load? You talking about too much charge current, what's the work of the mppt CC Bad advise tho

dollarnaira:
Lcd TVs are not energy friendly.
Your tv is more than my freezer of 115w, if not for start up surge they would be equivalent. Save up to buy used LED 32" tv of 50w at max settings.Normal setting is just 36w.

Thanks

Hey guys I have a Samsung TV that's rated 130w but I think it's more than 130w cos it drains my ba3 fast.

It also uses plug in adapter and it's lcd

dollarnaira:
Old or new type

Old model

Guys my Cc is showing my battery volts as 12.2 while the inverter is showing 12.6v, which one do I follow? The Cc is PowMr

Guys can you use change over switch in place of circuit breaker?

Again what's the best way to connect 2 Pv of 12v system

jplambert:
Don't buy solar generator, if your fridge is around 100watts, get modified sine wave Inveter of 3kv (price is around 70k) and your 750k will be enough to set it up. Ensure that you have circuit breaker installed on your system btw

And your fridge can't be on power at all time because it will drain your battery. No solar gen of 750k can run your fridge 247

I am not an installer or selling stuffs but just giving advise based on my experience and what I have learnt about sola so far

Guys can you use change over switch in place of circuit breaker?

Again what's the best way to connect your Pv of 12v system

lovediehatelive:
Nepa hardly bring light.

And I don't have inverter.

Just panel, charge controller and battery

Bro you bought panel, CC and battery just to be charging your phone with usb?

jplambert:
It depends on brand

Some good brands of 1k that cost 120k still in the market

It's mercury a good inverter brand

mctfopt:
Just checked again. Thought the temperature is voltage. Lol.

Some installers are crazy. Why would an installer opt for 6p after swapping out a PWM? THAT'S the problem then, Kendzyma get your installer to go and change the configuration to either 2s 3p or 3s 2p. He did 6p which is the reason the charge controller is running very hot, low voltage and high current are often recipe to high temperature. Also your MPPT won't work well at such low voltage. That'll explain the poor yield too.


That controller is not bad, I have friends using it without issue, just remember to set the battery type you are using

Bro what is 2s 3p

Do you have Easun sachet inverter?

Gshems:
Minimum 500k.
There is no way you can get a 220ah battery less than 280k currently, 1kva inverter like 100k, charge controller 80k, solar panel that one is on drugs right now. Wirings and all nothing less tan 50k. You go spend pass 500k sef.

Brand new 1kva inverter is at 170k now, where did you get yours for 100k
