Let him confirm the VOC first.

It might not be fake.

Just to let you people know, there are some solar panels modules, manufactured specifically for pumping machine and others applicance that requires high PV.

There are very rare to find

OK.We learn everyday

stuffs2002:
Good evening solar gurus in the house,

I have four 250W solar panels that I intend to connect all in series and they have the following parameters

Maximum Power Pm = 250W
Vmp = 48.7V
Imp = 5.54A
Voc = 60.87V
Ioc = 5.14A

I am of the opinion that I would need an MPPT charge controller with a solar input voltage up to 220V.
Can anyone recommend any good MPPT that can accept input voltage up to 220V or more.
Anyone with a better idea on how to connect this solar setup is highly welcome.

The panels are fake.What is the name of the panel? No way a 250 watts panel will have VoC of 60v.Not possible

toscotech:
You mean famicare inverter is not good or the powmr

That particular famicare is not good.I guess people on the platform will be able to advise you on the best brand of hybrid inverter to buy.I don't use hybrid inverter and can't say which brand is good or reliable

toscotech:
Some tell me to go for this instead of that powmr

Don't. Its not rugged!

HeavenlyBang:
1. The 220aH tubular has likely been mislabeled and isn't actually 22aH.
2. Even if it's actually 220aH, when you factor in DoD, usable energy is about the same as a 100aH lifepo4 battery
3. Lifepo4 handles 0.5c charge and discharge effortlessly, tubular is more around 0.2c
4. Lifepo4 will bounce back much better after being heavily discharged. Tubular won't.

There's no reason to buy a tubular battery in 2025. Even a cheap, Grade B lifepo4 battery is better than tubular.

People must here the word if God in 2025. Surprisingly a good tubular is from 290k and above ,same as price of most 12.8v block LFP of 100ah.

Enyinne:
that's another angle to it ,that is if e go work .

It will work.The only difference is in the quality of cell but based on the capacity test Dam5reey did on the 12.8v cworth its not bad for the price really.That's my opinion though.They used harvested cells of 120ah capacity with remainder capacity of 100ah if I still remember the details perfectly. Moreover,the other block types do.you know what is inside? If not for the person volunteering to do capacity test on the brands can we ascertain what is inside.We will all end up buying at ridiculous average market price.

CuteMaro:
PowMr Vs Cworth, which will u recommend for batteries?

Based on review and pricing

Powmr Grade A cell #296k
Cworth Harvested cell #177k

You already know what you are buying.We all love Lamborghini but we nor all fit afford am

Dam5reey1:
Resting time is not needed, having them in parallel or separately will take same time.

OK.I get.Faster than doing it separately. Thanks for clarifying

Dam5reey1:
To clarify, the Model number and cells are different.

I don't really fancy series, but you can do it, ensure to charge both in parallel to Full, before then connecting them in series, this ensure the pack are equalized.

Someone who bought it also did them same.

When in series, charge to 28.6V, cut off at 24V.

This just confirms your review of the cell in cworth 12v 100ah.If not ,why a whole #200k difference .It means certainly the cells are of varying quality. All the same, they still try.Nothing stops them from inflating the price to 280k and one will still think its average price of most 12v 100ah block lithium.The price still makes sense though.

Just for curiosity, why charge then both in parallel? What is wrong in charging each separately to full voltage and then connect in series?

Here goes nothing. Lol

Nice!! Nice!!Nice!!!

Can we go back to sharing tips?

I'm tired after assembling my 14.3kwh pack. Came in here to check what gives and all I see is back and forth about who sells the cheapest.

I'm here for DIY tips only and any other thing related to RE. That's all.

Anyways my 14.3kwh battery pack looks good

It's good to do it yourself. Lol

Feed our eyes now,let's appreciate the Lord's doing

Dam5reey1:
There are 300Ah Cells, review is upcoming. Fingers crossed.

We dey wait oo bros.E don tey wey you drop review

Dam5reey1:
This is what is obtainable in today's market..

5 years warranty on Lithium batteries.

Correct!!!

JJacko:
If you had any sense of what true DIY is, you would be clamouring for those days when members here would collaborate to order cells from China and everyone got their money's worth. Instead you buy shylock battery still go keep, dey cap rubbish.

Sorry sir.No vex!!! I rest my case!!!

JJacko:
You nor get point, sorry.

So what exactly is your own point? A lot of people have patronised Valto here and never complained.If you feel his item is too pricey for you,just pass. You can't compare the economies of scale of Chinese manufacturers with an entrepreneur in Nigeria.I recently bought s 48v50 ah from him and I am impressed with the build and look ,even though I am yet to connect it as it's for use in another location. Don't try to bring down the hard work of anyone,e get why!!!

Hello My Ogas,

Please i notice when i use my inverter to power my Fridge , it light of the fridge flicks abit, not so much but its noticable.

But with nepa, no flicking is observed, what could be the issue, i use same inverter with all the appliance in the house with no issues at all.


Can any one help with what could be wrong?

Is your inverter pure sine wave?

I will like to know from experienced people here just for learning purposes: what determines the LVD on Lithium batteries itself. Is it set by manufacturers or is dependent on the type of BMS used.I was just wandering why some LFP will cut off at 9.8v,some at 10v and some at 11v.

HeavenlyBang:
If you want a setup for daytime usage only, the numbers would be significantly different. But still not within your budget.

You could probably set that up with a budget of 2m.

Also, I'm of the opinion that tubular batteries are a waste of money and time in 2025.

I know you must end with this your famous phrase

Please how much will clear 2008 Toyota Sienna shipped by Grimaldi RORO

dollarnaira:
Ah na true oo.
2nd life or not it is cheap.
But still some guys will bent on Tubular 220ah. That 220ah dey burst their brains

Compared to.the price of the Powmr it is cheap but the Powmr uses Grade A cells which were scanned and brought out the info.And you can't blame folks who stick with their tubular.They don't want wahala: Top balancing,bottom balancing,BMS cut off,waking up battery. Let's be sincere ,the LFP wahala small small.

What do yall think about this sp power?

Don't waste your money.Its not mppt.Pure PWM

Ajani2plus:
Good day every, please I really need advice in this my car issue. I drive a 2004 corolla (1zz) engine. Recently I noticed anytime I travel from Ibadan to Lagos I'll need to top atleast 1 litre of oil and within 1 to 3 weeks of driving 1 or 2 phase of spark plug gets bad with excessive oil but aside from this my car drives well even with a little top cylinder noise. I seeked the advice of my mechanic cause we were very close he said I should rebuild the engine and change wornout parts. I gathered some cash for the work and get it done. Now, no more leak or shortage of engine oil and the smoke is gone also the engine sounds verywell under (half engine) the problem now is after finishing the job and I took it out to test drive I notice the top cylinder noise came back and this time very obvious (we took the cylinder out for grinding) and also;
1. I can't climb a small hill but drives well on normal ground
2. Sometimes while in traffic and I put the gear on neutral, the rpm goes above 2000 and sometimes below 1000.

Engineers in the house pls help me.

Just replace complete engine or by top engine since your other half is still good.All this grinding,rebuilding on Toyota engine do not usually last.

bassdow:
if you continue praising any brand, before you know it, boys go begin impersonate those brands.

Another thing is, people who are price conscious, should avoid Lithium batteries because in their search for Cheaper options, they could fall for the FAKEs.

Those who can't afford replacing an entire 48-volts battery should avoid Lithium - With Tubular / SLA / GEL batteries, if you're (temporarily) unable to afford the entire batch, you could replace them individually even though it's not often advice-able but with proper balancing, it's workAble BUT in Lithium, a Single cell could render the entire battery bank useLess.
Yea I know about cell replacement BUT most people don't know how to do that and the few who could, often are far away. Let's not talk about their HONESTy + Reliability.

Some of us need that money made from selling bad / weak / condemned batteries. At least person fit sell, add the difference and get another battery.

So you see, Lithium might be very good BUT like everything else, has got it's PROs and CONs. Marketers / Dealers focus mostly on the PROs but you the consumer need consider their CONs also because at end of the day, should things go south, it's your funds on the line.

Very true!!!!

bassdow:
You don't just get the point Sir.
Not saying don't use Lithium, or that Lithium is bad.

my point is to be sure of the dealer, brand, and that you can afford it.

There are people who can't easily afford a battery. in fact when their battery goes bad, they need wait till they are able to sell it off, before adding money to buy another.
Such people got no business with Lithium battery becauuse they easily would be swayed by cheaper / lower price points. Same with those who wanna make some money from sale of their USEd bad batteries.

Also to best of my knowledge, it's much easier buying FAKE or sub-standard Lithium battery , than a regular deep cycle battery.

Every thing has got it's place.

Same way, there are situations best suited for SSD disks; despite how good they are, not adviceAble to use for long data storage (archival purposes).

Thanks to the likes of Luminous and a few others, at least person fit enter their showRoom buy and be sure to some extent.

All the issues with Lithium is due to proliferation of the battery by different Chinese manufacturers which is why I still like the Powmr sold by @linnovo.He gave a detailed capacity test video and dismantled the battery to show the quality of cells.Its charging profile is also suitable for most type of inverters.The only limitation for me is that it comes only in blocks of 12v and having to series 4 units for a 48v system.Even at that considering each has a 100AMP BMS and all cells are in series it should be fine but still worth investigating further

Compliant:
Thank you for your input Sir

Now, should I get 100A CC to replace the 60A CC since I am not upgrading the batteries now or I should stick with the 60A for now

My main aim now is to charge my battery faster without connecting to the grid

Await your suggestion

Leave the set up as it is.I really do not know what your concern is from the image but your batteries are already fully charged and floating at 27.1v.I am not sure you will get full current from the panels due to energy losses . I guess your panel connection will be 2 s2p.

jonescosmos:
Bro, toss this battery ASAP,

I had exactly the same issue with the same model of battery and SAKO 3kw 24V Inverter alongside 8pcs of 450W Jinko Panels, at nights the battery discharges like it's in a competition, The SAKO Inverter and Battery both refused to obey cut-off points and as such the battery discharges beyond DOD, I thought when day breaks and the sun comes up, the inverter will wake the battery up, but it didn't, client used GEN and NEPA to try to charge the battery, yet no power.

This horrible experience went on for days until I replaced the Inverter and Battery with Felicity IVEM 3KW and 5KWh Felicity Lithium Battery.
Now everything is up and running and the SAKO Battery and Inverter are both laying fallow in my garage.

Regrettably several other people have reported similar issues with SAKO products.

PLEASE STAY AWAY FROM THESE 2 MODELS OF SAKO BATTERY & INVERTER

Don't they have repair/ service centre you can send it to?

toscotech:
can the battery be series

Its max of 2units in series and 2 in parallel

Check their site.The product manual is there

Mathewrichard99:
Camry 2004? That's Camry Big Daddy. Any reason you are going for such an old model?

I think you should buy something of a higher model. Even spider is still a bit better. Camry are very strong cars starting from the years Toyota started making them.

If you still insist on 2004, Camry. My advise is buy the Camry that has good body, legs and internal features in top shape and bad engine. I have bought a Nigerian used car before with Tokunbo body and internal, even the inside was still smelling Tokunbo......but the car has bad engine. I negotiated lower to accomodate the replacement of the engine which I did immediately I bought the car.....atimes, it's better you buy your own engine, a real Tokunbo engine that you are sure about

,

You sabi the game! Best advice.I tell people when buying naija used cars,just go for one with good body and interior and factor the replacement cost of engine and transmission in your negotiation.Chikena!

Guys i need help


I just recently installed my solar
5kw battery
5kva inverter
100A solar charge controller
9 panels 450w

The battery charges full in the morning before 11-12 but after then, it stops charging until the next day

Why is this?
How can i solve

Do you have load connected? Do you use it? Whatvdo you mean by it stops charging? Once your load is connected do you.mean it does not charge and drains your battery? It would be best to explain further? Is it connected to grid as well?
