Very sad

BigDickProblems:
So what?

What exactly is this supposed to mean? Shut him up?

I do read some of his write-ups and I like it cos I learn one or two things, even while some can be too long and off point at times, I can just scan through it. But that doesn’t mean his contributions aren’t worth it.

I will rather hear everyone’s opinion than being a one-track-minded person who will believe everything in a faceless forum.

So please let him be, if you don’t like his opinion, block him or ignore. Shikena.

Is blocking a possibility here? Pls teach me how, master

Now he writes and replies to himself in everything.
This thread is gone

I have seen some recent cases of fire from Lithium batteries, and this has somewhat given me some concern. Maybe experienced people and builders in the house can educate us on how to prevent something like this and what to do in case of one. I believe this will go a long way for us. For instance;

My wires and protection are well sized based on recommendation.

My charging speed doesn't exceed 40 amps, in fact most times I am charging at 30 amps as my system is grid only.

My unit is in a well aerated space. Like super aerated and no heat whatsoever.

My bms is rated at 150 amps, highest I have discharged at a go is 120amps.

I am always monitoring my system and so far it's been bliss.

I don't have a fire ball or fire extinguisher yet, will be ordering one next week. How else can one protect themselves from a case of fire incident?

As long as you've all of these safety features you wrote, you don't need to be scared about fire.
97% of LFP installation fire incidence is caused by underrated cables, and other accessories. Every cable will heat up when you pass through it current higher than it can take. These cables are insulated by rubber dressings that will melt and catch fire and touch other things in the room and cause fire outbreak.

But why would a phone charger be 120w each? Damn!

There are some phones that can charge with 120w.
Those phones that can call heaven direct 😁😁.

Joke apart. I've a 140w charger. I charge my power bank with 100w. And i can charge pc with 30w at same time. But if you don't put any device to charge, it won't draw any watts. So the guy may have connected my phones to each 120w that 3 of them overpower his small inverter.

@ Oweniwe, inverters have power factor. That it's a 1kva inverter doesn't mean it can take 1kwh. Its a normal thing for your 1kva to take max of 600w if power factor is 0.6

HeavenlyBang:
1.8m but Haisic has an identical model for 1.3m.

The haisic's 8kwh wasn't complete. We don't know if this will be complete or not too until tested

Major Upgrade to My Solar Setup (20kW Hybrid System)

I just wrapped up a big upgrade to my solar system. It’s now a 20kW hybrid solar setup — built mainly on traditional off-grid components, but I also added some grid-tie functionality using Deye Micro Inverters in AC-coupled mode.

This project has been in the works for over a year, and there’s a lot going on under the hood beyond just the specs:

IoT & Control: Built a custom system computer using a Raspberry Pi 4 Compute Module running Venus OS + Node-RED.

Smart Automation: Created several Node-RED flows to keep the system efficient. One cool one uses the Solcast weather forecast to predict tomorrow’s solar yield and automatically decide whether to allow grid input — and how much.

Monitoring & Dashboard: I switched to Grafana for visualization. The new dashboard gives a detailed view of performance and energy data.

I’m working on a detailed overview (with schematics) to explain how everything is connected. Hopefully, it will inspire anyone looking to build or upgrade their own setup.

Nice..

Are you Othell yarwyck on TG?
This looks like Abuja doings

TechGeek777:
Brother I still dey wonder the way you take dey type all those episodes abi na litany I go them.

Abeg focus on your programming, make you no go call wrong function .

Na joke I dey oh, before you come for me too as I know say you get answers to every comment

He go soon write three pages of reply on top your head. Best is to ignore him. But even if you do, he'll still invent something lengthy in his head from nowhere and still drop.
He's like Thanos. He's inevitable.
The main guys in this forum have left and moved to telegram and tiktok. The joy is that he's not there. Let him remain here alone. The forum is his.

HeavenlyBang:
Thread has just gotten tedious. Steep decline from what it was months ago.

I've replied and mentioned the guy's name many times and each time I'm given suspension from the platform.

I don't know how someone can use emotionalism to hold his ego over scientific facts.
God help us here abeg!

ezebunafo:
Lol my company sacked everybody that went on strike that was induced by the union body,and told everyone they are free to reapply,but have to write an undertaking that that they will not be joining the union again,that's how the union died a natural death.

Hi... I'm naive and wishing to learn.
Why are companies scared of unions for their workers which is meant to protect their interests?

bassdow:
so as I no come act matured enough to keep mute, you come kukuma tell me.
Why not try ignoring me, maybe, just mayBe, I would get tired.

e funny say una dey talk without viable evidence, BUT expect me to bring evidence. MayBe you haven't observed I don't share pictures or videos. Those ain't my line of work hence no get such time.

Una wey dey quote figures, where una evidence. Even manufactures of the things una dey promote go shock sometimes seeing the confidence and figures una dey quote

Maybe you are not on Tiktok. Many guys here like damreey5 and others post experimental videos and do 5 hours+ of tiktok live scientifically reviewing solar DIY products.
They are doing the doings you are doing the talkings.

Dam5reey1:
Na why we dey Test oo,
I tested panels with Amazing results, many came and said I was making things up, I doctored my numbers.

They are pushing narrative of NOCT rating, just like 80% DOD on battery

But for the Bifacial thing, Good complete Bifacial panel is way better than mono in performance.

I will be tested Jinko 590w Mono Vs ZN shine 590 Bifacial in a real word scenario. Side by side on the roof.

Do a video of your results.

bassdow:
you guys need understand something, I no get time to dey do online searches just because I want to follow person talk. I don talk wetin I know. If you come talk something BUT only focus on the good (sometimes questionable) sides, and do like say e no get bad sides, I go tackle una gain. If una like, use 5 multiple accounts, You no fit shame person wey no get shame.

Una don succeed to make everyOne to dey struggle to find new solar panels when used ones dey. e enever do, na to begin suggest and push for Bi-Facial panels, with no regards as to whether potential customers would be needing such or not; e no concern una so long money dey enter una pocket. Later na una go still yan say Tinubu do this and that like say if una get 5% opportunity, una no go do worse.

Oga don rush quote 30%; some traders go even try convince you say both sides dey give equal harvest hence if one side break, you fit turn to the other side. me ma kukuma be M U M U + Confused Mutula by default, as you dey try confuse and deceive me, na so i go dey look, hardly can you tell when I'm confused and when I'm not.

At end of the day, You win, the Customers loose. OverTime, said Customers loose interest and everyOne groans and put the blame on China and FAKEs

"TIME TO DEY DO ONLINE RESEARCH"... Not surprised. That's exactly what i expected you to do. Online research, to get the tradeoffs. I thought you had practical verifiable experience, but of course you no get.

I'll advice you just keep quiet on such issues or give your opinions as "your opinions" and not as facts.
You then went on writing a long litany of emotionalism which works on no one here.
Talk with facts! Here is a science lab - not ted talk space

bassdow:
How many verifiable proofs you drop. My own na to respond to, so if you drop your proof, then I go respond. Merely looking at your own comment, answers are there already.

You're Dropping, I'm Responding, Equation go balance

Yes, i dropped that answer coz we all know that those new brands reduce price. That point has to be taken off so that you can give us those other things that you know. You made it sound as if there are quality issues or hidden "tradeoffs" that you know and we don't know. We want you to assist us.

bassdow:
That 30% is often very rare and requires utmost optimum conditions. It's mostly theory BUT a customer is after real world values. A more realistic figure ought be around 5% to 15% best case scenario. Anything extra is just extra and should be seen as temporary.

Major issue is, a lot of people have their bi-Facial solar panels installed just like regular Solar panels. Doing that is just unnecessary waste of resources.

For those saying it's cheaper or same price as single faced Solar panel, na Lie Ooo. Even if dem subsidize the price on the receipt (to encourage more people to buy them), there are other costs and trade-offs.

For potential buyers, except you willing to meet the minimum requirements, you better off increasing your panel count, except of course space is an issue. A lot of roofs (if considering the roof) these days are not really that strong + how many of us even have reflective roofs (actually it must not be reflective) + for safety reasons, you need account for thicker cables, fuses, etc; + ...

For scientific purpose, can you cite the other costs and tradeoffs?
Cite with proof and maybe you'll help this community to be well informed.

Why is ZN bifacial 610w 108k but Jinko 590w is 125k apart from the fact that jinko is the bigger company and ZN and JA are trying to penetrate the market? Tell us the tradeoffs bifacials have coz you seem to know something we don't know.
Let them be scientific and not speculations

bassdow:
if you understood the meaning of that BI , then you would know the answer to your question is a Capital NO

Naturally, I always often discourage clients going for such. The extra cost is never worth it coupled with the fact most times, we mount flat on roof top / car port

Just buy yourself the regular solar panels, go for MONO and be done with it

Most Bifacials with higher wattage are cheaper than front alone panels. A bifacial of 610w is rated with the front and not the back. With the back you can get 30% above rated capacity. So you can use them on roofs if you want but you'll get more if used on a reflective place that gives the under sun light

lilachiever:
Hi boss.

Could you suggest reliable brands of inverter, battery and PV for a 5KVA and 10KWh Lithium battery setup for a total installation budget of 3.5M?

Will appreciate.

8 x ZN 605W Bifacial N-Type Solar Panel (fouani or any other 555-590w) - 8 x 110,000 = 880,000
Growatt 6kW inverter - 600k
10kwh from brands that have confirm 10kwh is around 2.1m like Firman. But you add 200k you'll get 16kwh of confirm quality batteries from Valto 2.3m. Or you get 15kwh same quality from Mrreed for 1.6m only that his has no communication ports and DC breaker, which are not necessary features and cheaper at 1.6m over that of Valto that is 600k costlier with breaker and communication ports. 😭😭. I'm sure you are asking same questions with me about why he can't reduce price too. Only that Mrreed often runs out of cells cuz of people rushing him.

Total cost = 3.1m to 3.8m.

Make your choice

Commentor:
Do you guys pretend to act lame or you truly are?

Do you hide your head in the sand for convenience or simply avoid the truth because you have some set beliefs?

The internet is there for you.

You can act ignorant until this is brought to your doorstep.

Just as we told you what would happen when the Tangerine Cheeto Mussolini is elected, now it is legal to racially profile anyone including you tour parents and your children.

Continue running defence.

You just typed 76 words without making any sense. What are you saying?

Commentor:
He prompted ABC to fire Kimmel.

You think ABC and Disney, the most leftist companies, can be prompted by Trump?
Lol

[quote author=Commentor post=136836768][/quote]Thank you. That's exactly what i said. He's thanking ABC for cancelling his show and he's happy for it. But it's not him that did it. He has no power to cancel a show except the owners do it

Commentor:
No matter who he cancels, he can't cancel his name from the Epstein files.

All of una get really poor comprehension clouded by emotions.
Una read or listen to the video? It didn't even say or suggest that Trump cancelled the show, but poor comprehension and bias just made you make that conclusion.

Jimmy made some weird Charlie comments that triggered various sister stations to say, sorry we won't show this guy on our TV again. Being bad for business, coz views bring in the cash, the parent company of his show put his show on suspension indefinitely.

Of course Trump will jubilate and be happy with this, but doesn't mean he's the one that told ABC to cancel the show. Mek una de try listen

cococandy:
Fascism is characterized by a dictatorial leader, centralized autocracy, militarism, forcible suppression of opposition, belief in a natural social hierarchy, subordination of individual interests for the perceived interest of the nation or race, and strong regimentation of society and the economy.

Then it means we don't have fascism in USA if this is the meaning

Mostly from new sponsor.
This year no Europe, less home matches, and already removed from EFL Cup by a club called greenbeans. So next year, revenue will be about £150m only.

I'm being truthful. This is my club and we are a mess now. But I'll die a united fan even at relegation

Valto:
he don't seem to get it. some username are already flagged. there are things i can't post with this my moniker, but can post with an alternate one. seun is a follower of this thread

Choi!
That explains it then.
Seun abeg na, help your boys if you too like DIY solar stuffs.

Dam5reey1:
This thing you did now, na only you if i post same it will be deleted.

If its true, then be like dem don bookmark una wey be sellers. Any pimmmm ! Delete 🤣

But I'm surprised the picture own gets deleted too. I mean putting the price encoded in a picture. I no wan believe say nairaland don advance to get OCR decoding from images.

Valto:
thanks for understanding. i tried posting a picture yesterday and i was banned 6 consecutive times,the bots allows picture or post anytime it likes

12v 4kwh - 400 k
12v 2kwh - 350 k
24v 8kwh - 800 k
24v 7kwh - 700 k
48v 14kwh - 1.9 m
48v 16kwh - 2.1 m

These are not real prices. But if you can see this without me getting banned, it means you can post prices but put the k a space after the numbers.
Bots obey commands and if you use what isn't included in their command they can't see you.

True fact is that you are losing customers by making them make extra efforts to get prices.

Except there's a nairaland admin among us here.

So fast!
7000 leads!

Whereas we've over 400k leads to catch bandits and Nigeria can't catch one

BigDickProblems:
Wow, this is interesting. I would like to hear more about this experience.

Because I always wondered why Oraimo and many other Brands uses Lythium-polymer (Li-PO) battery type that swells up in less than a year of use. So this also happens to LifePo4 if I get you right? Is it also after or almost attaining their complete cycle count?

Every lithium battery expands and retracts. That's where many builders insists on compression of cells when assembling.
Lithium is very sensitive and will catch fire and explode when punctured. But when mixed with phosphate, it reduces or hinders that fire issue during puncture depending on how the lifepo4 is produced. That's why LFP is safest lithium battery for home.

Yes, lifepo4 will expand and swell if you keep it at high charge for long. That's why it's discouraged to have LFP cells stay at 3.65v or anywhere near it. This is where BMS comes in to ensure you don't let it get there or stay there for long.
Most keep there cells at max 3.5v or even 3.45v so that LFP cells can last for decade+.
No matter what you do, after 5 years for example, if you disassemble the cells you'll see bulges or little belly in the cells. That's normal and they are still very good as long as it isn't exaggerated.

So, when bms is damaged, current won't stop entering the cells and they will swell beyond point of retraction and could explode.
