When i see people painting masturbating doom and gloom makes me ask which is bette; As a man which is better (I) masturbate and maintain control or (ii) get a girl pregnant when you're not ready and put her at risk of abortion and potential lose of life

Which one is potential lose of life? Every abortion involves a loss of life. The question is how many lives, one or two?

CuteMaro:
Just saw your video. Haisic performed quite well for the price.

So apparently, the most popular brands flying around here have been short changing customers

Buyers beware, stop buying names. The best bang for your bucks apparently are;

DIY from Valto and Mrreed (Untested though)
Deriy
Firman
LVtopsun
Deye
in no particular order.
and Haisic.

Chief please test Sako if you can, those guys have suffered some bad PR in the past, maybe they can use this opportunity to redeem themselves.

The DIY have been tested. You may just need Ray to add to his own test catalogue.

The only reason they won't is that they are mostly resellers. When they test, they direct people to where to buy. DIY won't favour their business.

These big brands also have aftersale services of 5+ years of warranty so if cells or bms fail, they'll easily direct to aftersale centres. DIY like valto and co won't guarantee you that though their battery packs could outlast any big brand battery packs. Buyers want to hear stuffs like 5 years or 10 yrs warranty. Doesn't favor these reviewers.

Its coz we are poor in skills but rather rich in gossips, yahoo, saidboj or gehgeh.... If not, in US or Europe, every solar savvy person builds his own battery pack by himself. No one or just few depend on batteries from brands.
With DIY, you are sure of your cells and bms.

Valto:
i don't use Hithuim and has never bought any. i use brand new grade A Gotion cells and it is 12000 cycles!. i also use EVE cells.

Oh. That's beautiful.
Didn't know Gotion had 12k cycle cells.

Now, did they say 12k cycles at 80% or at 70%?
That's if you understand the marketing strategy remark i made.

ValtechEnergy:
Valtech Energy 24v 7.5kwh/ 8.5kwh and 48v 15kwh/17kwh lifepo4 lithium batteries available
proudly assembled in Nigeria with brand new real capacity cells of 12000 cycles and smart bms!

Valto, this 12000 cycles of Hithium has been proven to be market strategy.
Every brand calculates cycles with 80% capacity but hithium does theirs with 70%.
Even the batteries with 6000 cycles at 80% could also meet or surpass 12000 cycles at 70%.

Its just marketing so as to use figures and attract people.
Nonetheless, hithium cells are good cells when you get their grade A which i know that's what you have.

CuteMaro:
I see nobody has mentioned battery capacity tests done by DIY WITH RAY on tiktok.

The test was conducted between Felicity, Firman and Cworth Batteries all of 10kwh capacity and the test results were quite interesting with the most popular brands failing woefully.

I will suggest people refer to battery capacity tests before recommending any brand. The market is a mess.

Only Deye, Firman and Lvtopsun got full capacity.
When i saw the cworth own i knew it was a waste of time coz I've 20kwh of cworth and I'm sure that thing has like 14kwh or so in it. You can never be sure of what batteries these brands put in their batteries.

The DIY batteries of Valto and mrreed are also only ones you can be sure of capacity. That's why i always go with them plus more affordable.

bassdow:
wait till they use a single teacher who already handles 3 subjects to teach them Solar. Funny enough, e fit be say the only solar panel the person don see na for other people roof.

Dem go just look introTech teacher, tell am say "You should be able to teach the pupils "solar photovoltaic installation and maintenance" na

All of una just drop pessimistic views.
Many no go do am, but some schools will and that's a win

New Nigerian curriculum for secondary schools now include solar photovoltaic installation and maintenance from js1 to ss3.

Nigerian kids could be experts in solar installation before they are done with ss3.

Hope every school adopts this.

Solar installers here can also apply to schools as part time job.

CuteMaro:
Does this mean inverters that support this feature ( can working without batteries) have the ability to wake a dead lithium battery caused by bms shutdown?

That's just another feature that hybrid inverters may or may not have. Even external charge controllers come with this feature while others don't.

bassdow:
Only came here to see if possible to get an inverter one is no longer actively using for whatever reason so long it's still functional or repairable BUT if after a while I don't get any, would just look into getting one just for this experiment. Hopefully if it works out, una no go want to know how far. Just sharing the intention here is enough for anyOne to try actualizing it especially since some of una don already voice out how easy it kinda seems.

When you succeed pls share findings and result with us since we all want to learn.

As for inverter that no one is using, we no get.
But if you wan pay for the inverter for the experiment, ehen, then that one we get inverter to give. 😂😁

bassdow:
Might have been somewhat mistaken in my last comment. Not often easy making comments while almost at same time moving from screen to screen.

Either way, got my guesses, theories, and findings and would need put them to action. Once again, if it were so easy, why isn't such feature mainstream after all both Charge controller's battery output and inverters battery input are both paralleled to the battery's connectors.

Actually, inverter doesn't get DC from battery. It gets from dc bus. It just happens that it's the battery that's connected to the bus. When you parallel your cc to battery, that cc output still enters your dc bus via the same battery cable. That's why when your battery is filled up it stops charging and your load in house is inverted from the dc from the cc that's hitting the dc bus.

Once you disconnect battery, the cc also disconnects coz it has nothing to clamp it's voltage on. That's why that inverter will only work with battery.

For the inverters that have the solar alone capable feature, they add something to the bus bar as earlier discussed that regulates and stabilise current. It'll now be like virtual battery such making the CC to continue to output dc into the dc bus without cutting off when battery is removed.

Every inverter can't have it. There's why it's an optional feature. Also the less features you've in these inverters the better. The more the features the more likely you will get faults. Manufacturers like to keep things simple. If you want added features, pay for it, but e fit de spoil any time. That's why your old simple transformer inverter of 2015 is still working till today, but new ones don't last 2 years 😭😭.

Good luck man.

HeavenlyBang:
No reason why it wouldn't work. DC is DC at the end of the day. You just need a panel that closely matches the battery voltage range and stable output.

I'm not sure an inverter would be able to tell apart 13v from a pv vs 13v from a battery, though I expect the panel's output to be noisier/less clean.

That's what i just told this bassdow guy and he's saying a charge controller can't regulate high voltage from panels. Lol.
DC is DC.
All those inverters that work with only solar panels do is that they add the DC from charge controller also into the DC bus that the battery connects to. Then they use capacitors and electronics to clean the noise and the inverter picks it's DC from that DC bus and inverts into AC. The inverter doesn't know difference between 54v from battery and 54v from charge controller as long they are in same dc bus and clean.

bassdow:
Cleaning up the ripples (what we mostly call noise) ain't the only thing that's needed to be done. Without a fixed voltage source source as the battery, the charge controller got no way to regulate it's very high voltage down to what's required e.g even a 12v rated charge controller can give upwards of 20v. It's the battery that brings it down. Same thing that happens when you connect a strong battery / solar panel to a weak or small battery / solar panel, the strong one comes down to level of the weakest one.

Another is the inverter could decide to draw large current which the charge controller might not be able to supply hence one risks damaging the equipment. So it's not all that easy though seems doAble from the little I have looked into BUT then again, theory and practical differs.

if it were so simple, I presume it would have been a mainstream feature of all inverters

I no come understand you again. You just said a charge controller can't regulate high voltage whereas that's the primary work of a charge controller. This is funny 😁. All a charge controller does is to step down DC voltage to the voltage you set it to. It can receive 300v 12a and step it down to 12, 24, 48v or any figure you set it to, while it increases amps or regulates it accordingly. Every charge controller is a DC-DC converter.
You thought only battery can give 48v for eg? 🙆🏾‍♂️🙆🏾‍♂️.

Anyways.. I guess you've already figured it all out.

bassdow:
There seem to be a communication gap here.

Once again, There's a feature in some or most Hybrid inverters whereBy they can directly get their supply from the Solar panels. Such feature never exists on non-Hybrid inverters.
Have often wondered why the Inverter can't just draw current directly from the Solar panel since the output of the charge controller, and the inverter's battery cables are both paralleled to the battery.

I need not put a charge controller into an inverter. That's not the aim. The aim is to figure a way to power the inverter directly from the terminals coming from an external charge controller so long it's output is stable enough. Of course we know one of the battery's role is to take care of noise while also ensuring voltage doesn't go higher than necessary. I believe it's possible.

There still would be need for a battery BUT the priority would be more when there's enough from the Solar panels, clean it up and use else rely on the batteries. That way there would be less strain on the battery.

mayBe I'm not explaining it well enough BUT I know what I wanna do; just don't have an any how inverter for such experiment

Now you explaining yourself better and it's clear your intention.

My guess!
The difference with inverters that can work with solar panels only without battery and the ones that only work with battery is DC BUS.
In the ones that work only with battery, the DC BUS is connected only to the battery. Once battery is disconnected, inverter goes off.

Whereas, the inverters that can work with solar panels alone without battery, they connect the mppt to the same DC BUS that battery connects to. Since the MPPT is already a DC-DC converter, it'll just easily get required voltage and dump into the same common DC BUS that battery is connected to. It'll surely need capacitors to clean up ripples from the MPPT DC voltage. All the inverter needs is to get power from the DC BUS be it from battery or solar. It'll only go off if both are disconnected and DC BUS is low or empty.

Again, my guess!

All Gehgeh says is for the good of women and the country.
Women need to start hustling and be productive for themselves and for the nation. Learn a skill, women.

Your only skill can't be tôoto. You are ruining our nation and yourself.

God bless Gehgeh.

mctfopt:
My question. Is what size of cable does this user have to be able to do this?

16mm²?

35mm²?

120mm²?

The answer is that it can. Once you parallel batteries, the amps drawn are shared among them. If he draws 300a and both have 150a bms, it'll work well safely if the battery manufacturer confirms that cells can discharge at 1C.

As you rightly questioned, he'll have to have wires that can safely carry each 150a (35mm). And if he plans to use combiner busbar, it must be rated 300a, and cable from busbar to inverter must be rated for 300a (95mm) and then inverter must be rated to take in 300a, most of these being unlikely 🙆🏾‍♂️🙆🏾‍♂️🙆🏾‍♂️🙆🏾‍♂️.

But yes it can.

bassdow:
Thought I was clear enough.

There's a feature of most Hybrid inverters whereby even without a battery, they could function and even in presence of a battery, they could still directly draw from the Solar panel.

The non Hybrid inverters don't have such feature. In fact they need the battery to even power themselves first before anything else. And while in operation, should the battery go low, they would disconnect even if the Solar has got enough.
So I thought if I do a couple of things, should be able to get such feature onto a non-Hybrid inverter

Then it means you want to put a solar charge controller into the non-hybrid inverter and make it a hybrid. That's Cool stuff.

The feature for an inverter to run from solar power independent of battery isn't a core hybrid feature. Many hybrid inverters don't have that feature though only a hybrid can have it since it has charge controller for solar panels. It's just an extra feature that hybrids may or may not have like supply to grid, power priority feature, etc... What makes an inverter hybrid is just one thing alone - that it has internal ability to get power from sun. Shikena.

bassdow:
Only trying to say I needed non Hybrid inverters.

Though if I get a hybrid inverter, might have to strip it down to bare minimum though not sure how possible BUT major focus is for non Hybrid inverter

Hybrid simply means it has internal mppt and communicate with grid.
When you say you want a non-hybrid inverter to use like a hybrid inverter as u said in your original post, you wan chook mppt or solar harvestor inside am? Abi you used the term hybrid wrongly again as many people often do here?

Allah ya tamaike mu duka a cikin wanna duniya.

Pakistan’s 22 GW Solar Shock: How a Fragile State Went Full Clean Energy

Michael Barnard

[b]Pakistan isn’t the first country you’d expect to crash the global solar party. But by the end of 2024, it quietly rocketed into the top tier of solar adopters, importing a jaw-dropping 22 gigawatts worth of solar panels in a single year. That’s not a typo or a spreadsheet rounding error. That’s the kind of number that turns heads at IEA meetings and makes policy analysts double-check their databases. It certainly made me sit up and take notice when I first heard about what was happening in mid-2024.

No be same country the locals went to a solar harvest field and were breaking hundreds of panels with sticks and rods by both men and women coz someone told them that the installation of panels is interfering and stopping rain from falling down?

After doing such mega projects, they should endeavour to educate the people.

There's a reason solar renewable energy is used in 3rd world countries more than 1st worlds who already have stable energy albeit unclean. It's when your power is epileptic that you've no option than to adopt more affordable and accessible options like renewable energy.

bassdow:
I am looking to perform a little experiment where I get to use a standard Inverter like it's a Hybrid inverter.
I mean with regards the fact there are inverters that could function without a battery.

Issue be say I no get inverter wey I fit use do that kind experiment. If e get any body wey get inverter wey we fit use do that kind experiment, abeg make e try contribute abeg.

I want something wey be say if e spoil along the way, I go fix am continue. I no fit comfortably do that kind thing with expensive ones.

What do you mean by using standard inverter like hybrid inverter? What is standard?

Lemme pepper felicity haters.

This is the best low frequency hybrid inverter in felicity line. The IVGM series. 5,8 and 10kva.
Has same IP65 features against dust and water like the IP65 Deye, but more affordable.

Wahala is that it came into Nigeria and it got finished immediately.
Same with their new charge controller that now has inbuilt WiFi. Nigerians finished them immediately.

When they make this developments, you begin to give your solar equipments wey dey house side eye like you can't wait to change them.

joelbooks:
Do the math. If 99% of men cheat, who are they cheating with?
Other men? No.
So, who then? Women, of course.

That means:
99% men cheating = 99% women involved.

Conclusion: If 99% of men cheat, then 99% of women cheat too.

Only people in commited relationship can cheat. If a married man cheats on his wife with a single lady, only the man cheated. A single lady cannot cheat. A single person can't commit adultery. For them it's fornication. For a married man or woman it's adultery or cheating.

I didn't believe i had to explain this

BangaRice:
Good morning fellow enthusiasts,
I need the most budget friendly inverter that can

1. invert 12V DC into 220v AC
2. Use Grid power to charge backup battery when available and switchover to solar when appropriate.

Th set up is just 300w panel, PWM controller and 100AH battery.

{PASTED AGAIN FOR ATTENTION}

You may almost certainly not get an answer. People here have left such small systems which includes pwm for a long time.
Just go get any 12v inverter that has charger function and that's all.
Sure i didn't answer, but at least i responded 😎

I don't like it when people make good comments about Abuja. You want to be attracting population and Lagos nuances to Abuja ?
Pls leave our Abuja alone.
Its not a good place to live in.
Dem de chop human being for here.
Remain in Lagos pls

fuckboys:
you’re been too paranoid. I don’t know how old you are but I’m sure you’d probably be long dead before your LFP cells hits 70% DOD.

Everybody should just do whatever they feels is right for them.

Not every caution is a clinical paranoia coz be like you wan talk se i don de mad 🤣.
You take cautions for your personal car coz you want it to last and not coz you are paranoid.

Meanwhile I'm 38. Saying i won't see my battery get 70% DOD mean se you wan make i die before 60 years . Oga, u no good aswearrrr lol

Dam5reey:
Oga, you are just emotional, your Analogy no follow!
This is a product review!

Only that it is a wrong product review.

As emotional as it was, you know se e go pain you if dem do am to you. But e de happy you now as you do am to another brand using a product that THAT IS NOT THEIRS

fuckboys:
I'm sure you know what absorption and floating means?

At what voltage should n lfp cell be done absorbing and at what cell voltage should it float?

If you knew what the absorption and floating really is you'll know that the terminology applies to lead acid. Its only borrowed into LFP now.
LFP just has a charging voltage which you may call bulk or absorption from lead acid terms.
There are 1001 cv requirements based on brands and cell tech. Many datasheets will say 3.65v in the west. When they make it specifically for Africa and Asia they reduce. Even in the west people change their settings to lower cv. Practical setting for cv 3.45v-3.5v.

LFP doesn't feed floating for simple reason that LFP doesn't like to stay near 100% for long since it reduces lifespan. In the west, many let their cv stay for 6mins when complete and let it go down and settle at 3.35v. If your inverter forces you to float, set it at 3.35-3.40v. That's sweet área for us for long lifespan.

But since e de shark us for head to de see 100% for battery screen, we love to leave it to float near full so that when sun goes down we are near capacity. I also set my cv and float to same though i know its not best practice.
That's why i put cv and float low at 3.45v. I know the disadvantage but me too want near full by evening. Just fooling myself coz in most LFP discharge curve, even that 3.45v is almost same as 3.35v.

obitobe:
This is my cells right now, I guess they are well balanced.

Over balance de worry am.
Keep this settings pls.
Don't let anyone deceive you to go to higher charging voltage.

Dam5reey:
What are you saying oo
My 52 usd is at stake, send me original product if you are interested in cleaning up the air, else you are just part of the 1000 Adviser, Zero help!

I don't work for them na. You are only expected to be human and do the right moral thing after wrongly tarnishing a brand after your mistake of lack of research.

You are a solar guy who have given yourself good name for years. If a scammer claims to be you and uses ur name to steal a project where he installs rubbish... It catches fire after 2 weeks and the scammed client goes online to say Solaris surge or Dam5reey is the worse solar installer with video proof of his burnt setup and house. A project you knew nothing about oh.
Someone recognises the scam and tells the scammed client that the guy who scammed him isn't Dam5reey oh, he scammed you. But clients says I don't care, let the real Dam5reey come and install a new setup in my house for free to save his name. My 6 million is at stake instead of saying, ah, i was scammed by one electrician Femi who isn't Solaris and I'm sorry for spoiling the name of the legit company. I sure you go like am.

See as you don make me write long super story to prove a point wey no concern me 🤣🤣🤣🤣🤣. Just be human.

Dam5reey:
The company should find my video and send original one.
I bought that toy for 52USD, na me go still correct what?

😂 Did you even read your comment? You were deceived by fraudsters and went to buy a fake that doesn't even exist in their catalogue from a cloning company. And you expect the real company to come and save their name and send you a good product? 🤣🤣🤣🤣.

"Guys I've just realised that i got scammed and bought a non existent fake version of this company's product. I retract my comment about calling the company product a toy until i get the opportunity to test their real product someday"...

Dam5reey:
Always buy ke, these things are not cheap,
Buy and send me one for science.

Lol... But at least you do acknowledge what i told you about the elejoy tester - that you got a cloned fake device.
One day you may need to correct the wrong notion the fake device gave you and which you told your audience so as not to destroy their good brand quality.
