numericalguy:
The inverter is a Luminous 24v/1.5KVA and does not have editable settings

Though I have solar panels and an MPPT charge controller

You are correct.

https://www.nairaland.com/6298302/luminous-1.5kva-24v-ion-sine

It does not have settings for various battery types.

Schneider has.

mctfopt:
This inverter doesn't die.

My cousin has one since 2015. Still rocking.

They did such a good job that Schneider either licensed the model or got the rights to make something uncanningly similar

2 used and in perfect condition Jinko 475 watts panels available for sale at 115,000 each in Abuja

Everyone is trying to do solar.

Something is wrong with these packages.

StarTimes Solar offers a cost-effective alternative, like the H25 package (3kVA inverter, 2.5kWh battery, two 450W panels).

Solutions like StarTimes Solar H50 solar package featuring a 5kVA inverter, 5kWh battery, and four 575W panels.

Can you tell?

GloryJoyeux:
Pardon me, I can see felicity in your teardown also. So is it Felicity that polishes busbars before coupling? Felicity whose earlier packs were known for harvested and over stated capacity cells. Felicity whose bms in earlier packs were notorious when it came to reliability.

Some DIY batteries are better than some of this so called professional coupling.

Just look at pylontech, industry name yes, but the are notorious for having failing bms, complaints about bloated cells, packs not charging to full etc

Eg4 batteries have numerous complaints too, i have also seen similar complaints with deye LV batteries etc

The fact that you are lucky that your installs don’t have problems doesn’t mean its same experience for everyone. A simple deep research will show numerous complaints on forums by users if this so called ‘better than diy battery’.

I’m telling you a fact which you can also verify by simply researching forums on the internet.

DIY is simply do it yourself, the more skilled the builder and more access to quality tools the builder has equals a better build. Full stop.

This back and forth has been invaluable.

In the decision to pick a vendor for batteries

clevermugu:
considering that u to wait for 2 or 3months after payment , before u recieve ,DERIY pack not cheap sir, heat fit kpai person before one week sef

Naira per watt, and you want it now Valto

Naira per watt and you can wait, then Derry

Sometimee one just cannot wait.

If you already have something to manage, and want extra then you might play the waiting game.

Say you have a contract and need to supply ASAP, you cannot wait

AdisaMighty:
Unsolicited advice alert!

Just look for an internship and grow from there.
Alternatively you can skip that, start something that solves a real problem and raise funds.

If I were to advise my younger self, I will pick the latter. You are very unlikely to ever become wealthy coding for a salary.

PS: I have been coding for almost 20 years, I have seen both money and lack thereof

Words on marble.

But he faces a chicken egg situation.

Learn code on an empty stomach or not.

That is to say without a means to survive he will find it very difficult to give learning to program the undivided attention it deserves.

Does he even have a laptop?

Access to the internet?

A stable accommodation?

He didn't say but you get my drift.

That said never were truer words spoken in response to his question.

Then the other issue.

It takes a while to learn to solve problems when school taught the majority to learn to follow directions. (The conflict between being self directed and following directions)

Finally, you need to realize that you will need to learn to solve several problems before you hit the one that is the equivalent of striking gold. He must bear this in mind.

Very rarely will the first problem you solve be the problem that results in a financial breakthrough

Peterlove11:
I bought 16kwh from him recently. He delivered directly at my doorstep in less than 24hrs.
I did capacity testing on it, was able to pull beyond 316ah from the battery, that was at 48v low voltage disconnect.
He used JK bms on the battery which I later read from reviews its a good and quality bms.
I will give the build quality a 8/10. Quality battery terminals and circuit breaker.
Concerning cycle life, he said it's rept cells with 8000cycle life.
In all, I will recommend if you want genuinely rated battery with good bms
This is based on the battery I bought from him, can't say about other capacities.

This review is both technical and detailed.

Thanks for taking the time to comment.

you may also want to consider huawei

fouani are selling them. my understanding is they are doing direct purchase from huawei.

Thanks for the heads-up

This is an objective question and not a diss or an attack.

What are the pros and cons of purchasing a battery from our guy here Valto versus any other packaged batteries?

I've read here that Felicity batteries overstate their capacity but that Valto states the real capacity.

What other issues play in favor of Valto?

If there are any cons, please share.

Want to make an objective purchase decision here.

This is going to be my first lithium battery purchase and I don't want to get it wrong.

Comments on the below will be helpful:

Capacity,
Cycle life,
DIscharge rate,
safety features,
Build quality

Will be helpful

This list is by no means exhaustive

bkuranga:
I have this POWMR 60A (pic attached) charge controller and 3 pieces of Jinko 590W panels with the following parameters.

Maximum Power Voltage(Vmp) 43.71V

Maximum Power Current(Imp) 13.5A

Open Circuit Voltage(Voc) 52.63V

Short Circuit Current(Isc) 14.13A

Is it okay to series this panels with this controller?
If not, can you recommend a controller that can do this work and give room for possible future upgrade?


@Dam5reey1, dollarnaira and other bosses.

You have missed an important detail.

What voltage does your battery run? 12v 24v 36v 48v

Search is broken.

Make the search functionality better.

Why limit results to 20 pages?

mctfopt:
Powerful awesome inverter. If your area is affected by low voltage, as most places in Nigeria, get a good voltage stabiliser if you don't have one. It doesn't tolerate voltage lower than 190v.

Though you can adjust this if you have an SCP. Not recommended to drop the input voltage though. Can charge up to 45A and handle crazy surges.

Note, you practically can't change anything (charging current, voltage cut off, LVD, etc) on this inverter if you don't have an SCP. An SCP is attached.

I have a Schneider inverter.

I can attest to the fact that even low current can be utilized by the inverter.

It will charge even when my SRNE refuses to charge due to the low current

dollarnaira:
Those stuff don't work except some car batteries.

Thanks.

This means I need to budget for a new inverter and lithium batteries.

Still serves but the back up time has reduced.

I have seen videos suggesting that aged AGM batteries can be revitalised.

But those were car batteries. Can thesame be done to SMF batteries.

Also if done, how many more months or years of service to expect?

My first set of AGM batteries are on their last legs.

How much does 48 volts 20kw battery cost on this thread?

Vendors make your pitches please

AinsSama:
Does the 9 hours include night time?

Yes it's sufficient. Can't say much about battery sizing without info on night runtime.

No, it does not include night time.

Also, in some ways there is over-estimation.

The printer does not run 24/7.

The computers can also go into standby mode when not in use.

The display units may go into standby mode, but I calculated for the worst case scenario.

If it were to be a 24/7 operation, I am sure that battery would be insufficient, but for day time loads of 8 hours + 1 hour overtime just in case, I felt it is adequate.

Your views are welcome all the same

dollarnaira:
620w available

How much?

swagifted:
So that shortman Coscharis no really be distributor?

Wetin the short man do?

AinsSama:
That's more than sufficient

Once again, thanks for chipping in.

AinsSama:
Yes it's more than sufficient. Even a good 6kw inverter is excellent, 5kw is also fine.

I appreciate your feedback.

Based on my calculations 5,430 watts running for 9 hours means 48.87kWh.

What is the appropriate solar panel and battery sizing for the above?

is 15kW of solar panels and 20kw of battery good enough?

HeavenlyBang:
A 7.5kw inverter would be running at effectively 67% capacity constantly. Do 10kw instead.

Thanks,

I appreciate,

Please recommend appropriate inverter, battery and solar panel sizing for the following equipment

7 computers each consuming 330 watts or 2,310 watts total

1 printer that consumes 20 watts

1 non inverter 2hp air conditioner that consumes 2,000 watts approximately

2 display units that consume 550 watts each or a total of 1100 watts

Assuming that I need to power these for 8 hours non-stop and I also need the battery to be fully charged at the end of the day.

Will a 7.5kw inverter do the job or should I make it 10kw?

Thanks for your advice

Not if they are using WhatsApp, Signal, Telegram or other such means of communication?

Don't be so sure.

I had to relearn too when Drugs/medication almost put me in trouble. My neighbor his gf was sick and she went to the pharmacy to get medication, when the BF came back and asked f I saw her, I just innocently said Yeah I saw her she went to get drugs. The guy shouted WENT TO GET DRUGGSS?

Before I quickly corrected that I meant medication

A relation here in Nigeria always makes this distinction.

Drugs bad

Medication good

From him I learned to not use the two words interchangeably.

Tareq1105:
I prefer to pay #2,000 toll fees from Abuja on a very smooth road than to spend #100,000 on repair of car after arriving makurdi. It's all about being reasonable.

Which road will lead to such a repair cost from Abuja?

If your family is not blessed with a lawyer

Please try and get a lawyer as a friend

And ask him to explain to you as a friend what the problem with your position is

I have seen both lawyers and non lawyers explain to you that you are wrong

But you refuse to see the wrong in your position

This is the exact same mentality that operates when a soldier is killed by a community and then the Army invades the community and destroys every living and non living thing

Law is about balancing of rights, the rights of the accused and the rights of those not accused, the rights of the criminal and the rights of non-criminals,

One of the cornerstones of the American legal system is Blackstone’s Formulation. Sometimes known as the Blackstone Ratio, it is about the balance between protecting the innocent and punishing the guilty. In the American criminal justice system, you are presumed innocent until proven guilty.

William Blackstone was an English jurist who authored commentaries on the laws of England. Blackstone lived in England from 1723 to 1780. English settlers in the American colonies took his legal theories and used them as the basis for the American legal system.

The exact quote from Sir William Blackstone is, “It is better that ten guilty persons escape than that one innocent suffer.”

The goal of Blackstone’s formulation is not to allow the guilty to go free. However, it ensures that the innocent are not unfairly jailed or punished.

I hope you will never immigrate to where the law is practiced in a fair manner.

By your words, you belong to the jungle. I hope and pray you remain there.

The presumption of innocence is a constitutional right

Bank toilets in Nigeria are cleaner than government hospital toilets

Bank toilets in Nigeria have a pleasant odor while government hospital toilets have a very unpleasant odor.

Let me not get started on comparing the looks of both.

IyaTola:
When you're living in a house, it's actually more of a liability. Here's why:

1. *No rental income*: Since you're occupying the house, you're not generating any rental income from it.
2. *Maintenance and expenses*: As a homeowner, you're responsible for maintenance, repairs, property taxes, and insurance, which can be significant expenses.
3. *Opportunity cost*: The money you've invested in the house could be invested elsewhere, potentially generating a higher return.
4. *Illiquidity*: A house is a relatively illiquid asset, meaning it can take time to sell and access the funds.

While a house can provide a sense of security, stability, and comfort, it's not necessarily generating income or appreciating in value while you're living in it. Therefore, from a purely financial perspective, a house you're living in is more of a liability than an asset.

What if a portion of the house serves as an office? In short it is both a home and an office, then it maybe an income generating asset not just a liability
