With this price if you are patient and can wait 3 months for shipping, are willing to learn, you are better off ordering certified automotive grade cells and a diy kit and have peace of mind…..and for less money. To me there is a level of spending where he “F” batteries makes no sense for what they are. I am yet to see any review of any “f” battery where the tested capacity matched the claimed capacity.

F is for Felicity .

Lemme see what happens next

TechGeek777:


Thought they said lithium iron phosphate (LFP) does not catch fire nor explode?

There are too many unknowns in the case to have a definite cause of fire..

Eg, i received a batch of lfp cells from china, that were improperly packed..and this resulted in one of the cell terminals getting slightly depressed and puncturing the cell...with resultant leakage of few drops of whatever liquid the cell is made up.

However the cell didnt have an obvious damage.
A greedy person or seller could have simply wiped off the leakage and used or sold that cell....

That cell when then used to build a pack could be quite unpredictable. So i simply laid it aside...and its gathering dust in my store.

Nb: nobody shud ask me to gift them the cell...cos i won't

Post-mortem of the plug
@TechGeek777 and Valto thanks

You mean you connected your inverter thru this 13amp socket?.
800va is the max inverter you should ever connect to that type of socket

Obnoxious2001:


this is the power the pump will consume while working.
using 48v dc as input, you will need 13a to run this pump.....
you can always twerk it to get good result

so technically, his 1.5kva system can run the pump



aside that, who has experience with solar ceiling fan moving the other direction when is about to start
until you push in the right direction before its able to rotate properly

His 1.5kva system is 12v....no way it can run the pump. @12v..he wud need about 55amps...assuming the pump can even accept 12v.

@ fan, was told its something going bad in the fan.will get worse with time till the fan fails.

Obnoxious2001:


1.5hp is the power of the dc pumping machine.
this pumps comes in various design ranging from 48v upto 120v dc (the amperage vary).
a 1.5hp might 48v 10a
i attached a photo

Yes, thats the specs am talking about.
Only thing i dont understand is 600w and 1.5hp tag.
1.5hp is about 1kw...hence the 600w tag is confusing.the flowrate is healthy, though i expected much more.. 1m³/h is about 16liters per minute..that is about 1000liters per hour

Obnoxious2001:

buy high hp.
around 1.5hp should fill those tanks within 3hrs....
another thing you need to take note of is the depth of the bore hole

most pumps has a depth dey cant pump beyond

osayuwamwen:

thats maybe an inelegant way of solving a problem, throwing high hp at an issue. recall his major constraint was power- using his inverter to pump water. a 1.5hp sumo would require minimum of 4kw inverter to power it. unless its a dc sumo...then he would require minimum 2kw of panels to have a chance at it working ok.

any sumo has a ''head' as you rightly pointed out, this is written on the spec sheet of any decent submersible pump...and tells you the depth and flowrate of the pump. so a pump with a head of 200ft will work ok, be it 0.2hp or 10hp.....the 2nd consideration now becomes the flowrate, a 10hp might have a 100liter/minute flowrate while a 0.2hp pump might have a 20liter/minute flowrate.............so you then calculate your water tank capacity and usage to arrive at the hp that is optimal for your use case.

the inverter sumo i talked about has a head of 210ft/70meters and flowrate of 35liters/minute...and its being deployed for a single house with 2000liter overhead tank. works ok for that use case. deploying a 1.5hp pump there may deliver water faster, but would be useless as they just have a 1.5kva inverter which cant power it and totally offgrid

osayuwamwen:
Pls do you have idea abt the cost of 0.33hp and will it be efficient enough to pump for 3 tank of 1500 liters each?

It pumps about 2000 liters in 70 minutes.
Was about 120k i got it on jiji last year.
Now will it last being used daily to fill 3 tanks as u described...i have no clue, its made in china not europe.

If u have upto 300k, try grundfus pump, its made in europe very reliable but rugged

osayuwamwen:
Is solar pump same as inverter pump?

I dont know exactly what u mean by solar pump...but i guess its a dc pump you can connect directly to solar panels or battery.

An inverter pump is like inverter fridge....uses ac , has no startup surge, very efficient, and consumes low watts

osayuwamwen:
Can i use a solar submersible pump on my 12v solar inverter system?

An inverter submersible pump is even better.
No surge and low wattage.
Using one for my folks in the village 250w and 0.33hp...using it on a 24v 1.5kva luminous inverter....am sure a 1kva inverter will still work ok

We all know that very few people will be able to afford EV grade cells.
As many of us are dealing with non Ev grade cells generally known as grade B, we should try to adjust our marketing terms to reflect what we sell.
I salute Amy Wan, Gloria Basen, Cassie Wang and few others for their marketing strategies but Selina Li must step up her game. Telling people like us who are very inquisitive that Eve has grade A, grade A+, grade A-, grade with letter B QR Code and grade without letter B QR Code is not a good marketing strategy.

Interesting analysis, curious if you have ever bought cells from any of the bolded?....as their cells are 30% more expensive and i sense from your posts that you like a good bargain

kristien4:
its written @c20 rating. Then recommended maximum charging is 10% of battery capacity. I was thinking since its four battery connected in series 40amps should be okay... but i noticed a low bubbling sound while charging the 4 batteries(tubular)at 40amps current. Is it normal?

for series connection, current remains the same, voltage increases. @ c20 in series..10amps is the recommended charge rate if you want to play it by the book, but you can do 20amps without issues...anything above 22amps...you are asking for trouble...the battery will be heating up and boiling.

the 40amps would have been ok, for parallel battery connection, since the 4 batteries wud share the 40amps. in series..the 40amps wud go tru each battery -- very very wrong. you risk premature battery failure, shud you persist in doing this!!!!!

shogbenga:


Thanks @mctfopt

The total load is 4.45kw, less a/c and heater

you have all this on just 8 pieces of 12v 200ah battery?.. omo u get mind...those batteries will die/get weak within 1yr, seems you are not knowledgable and fell into the hands of kazeems installers. like the one I saw on Instagram, a so called experienced installer with over 400 followers, hooked up a 1.5hp sumo on 2units 12v 200ah battery and 24v 5kw inverter...and was bragging, on how rugged the inverter is ..... an less than 2 months I give such a setup, b4 the battery go die. lead acid battery is not designed to carry such humongous load.

back to your question your 8 batteries if in good health can only carry a max of 1.6kw, so you need to ensure your panels would bring in the balance of 3kw....and also because of the varying weather/suns intensity..you may need up to 6kw panels to ensure you are sure of producing average of 3kw all the time......then the wahala of this design is that you may also exceed your battery acceptable charging current, likely 20 or 30amps.......unless its special agm that you can do 60amps.

lastly for you or anybody running or planning to run such a huge load... best you for lithium battery...or 2nd best option, these 2v 1000amp or higher battery

Obnoxious2001:
Attention please I need your opinion.

In a recent installation I embarked on, I was having thoughts on Which configuration is best for a hybrid inverter system.
(3kva 24v)

Voc of the panel is 64v, 7amps
No. Of solar panels is 6pcs of 380w panels all connected in series (output voltage is 360+) charging a 24v 100ah lithium battery

Vs

2s3p (output voltage is 120+) charging same 24v 100ah lithium battery.

This system has a continuous load of almost 700w in total.

Which panel configuration is best

strange panels you hv got there 64v voc.....and 380w.. curious to know the make. have you rechecked this specs with a meter?.

since u say u hv a hybrid, only option is a series connection.

nasonaso:
earthrealm pls I need to ask some questions. My number is 0818seven8threesix063.Any installer in Benin or someone you can refer me to

Just seeing ur msg.
Unfortunately, i dont know any sound installer...i would recommend to work unsupervised.
Unless you are knowledgable and just need raw labour..i can link you to a couple of installers....but if u need a highly skilled installer ..u may hav3 to bring them in from outside benin.

I recall one of the installers i gave someone for a hf hybrid.8 panels.
The installer with over 8yrs experience just did 3-3-2 connection and turned around to say the hybrid inverter isnt working

I had to go physically to direct him on what to do.
E no bother read inverter manual or spec sheet....and who even does 3-3-2?

YOU KNOW how long cbn takes to effect a cancellation?

i cancelled my ist application, yet the lien hasn't been removed on the amount I initially applied for..hence am unable to apply for the maximum amount in my new application. the email to log a complaint on the tradessytem website bounced my email

semasir:
The era of going to the bank to apply for foreign exchange (Forex) in order to pay for school fees is now going away as the Central Bank of Nigeria has introduced the Trade System website.

Why the Trade System Website?

The website enables individuals and cooperate organisations to apply for dollars, euros, pounds or any of these to pay rather than just filling the form in the bank.

This platform gives an opportunity to even apply earlier even when you do not have the completed funds in your account since it'd log you on the queue to be debited.

Things You Must Have Before You Apply or Register on tradesystem.gov.ng

- As an organization, you must have a TIN (Tax Identification Number).
- If you are registering as an individual, you must have your email linked to your BVN

How To Register on the Trade System Website

- Enter the website on your device – www.tradesystem.gov.ng
- Scroll down and click Register Now
- Choose your category (Organization or Individual)
- Enter your Tax Identification Number (TIN) (if organization) or your Bank Verification Number (BVN) (if individual)
Choose your password
- Reconfirm password
- Click Continue. An OTP email will be sent to the registered email on your BVN.
- Retrieve the code and submit.

How To Apply for Dollars, Pounds or Euros Using the Trade System Website

Now that you have successfully completed the registration, you can now apply for your foreign exchange by entering the required information.

- Click on Login and enter the email address. An OTP will be sent to your email, copy and paste it in the box
- Click Start Application to begin your documentation.
- Step by Step on How to Fill the Form A For School Fees

- Upload sponsor’s identification (if the student is paying through a sponsor)
Enter the school fees amount (max $15,000 per semester)
- Enter the bank account number to debit
- Select preferred bank from the dropdown
- Submit

You can follow up with your bank using your AF number. School fee processing may take up to 1-3 weeks

Step by Step on How to Apply for the Personal Travel Allowance (PTA) on the Trade System

- Login to your account
- Select PTA/BTA
- Enter all necessary travel details
- Upload necessary travel documents (return flight ticket, visa page, and  passport data page)
- Upload the company’s letter of nomination and certificate of incorporation (in case of BTA only)
- Enter your bank account number to debit
- Select your bank from the dropdown
- Select the bank branch that you prefer to treat the transaction
- Submit

What to do after submitting your Form A Online With Your Bank

You have to follow up with your bank using your A-number. To do this, you'd need to get the contact details of your account officer so (s)he can follow up with your application.

PTA/BTA processing may take 1-3 working days but due to scarcity of Forex, it takes about 60 days to be processed.

Documents to Submit on Your Form A When You Want to Contact Your Account Manager

Once you are done finishing your form, it is advisable that you follow up with your account officer or the bank personnel who is managing your account.

These documents are very important to attach on your Form A application which will be processed by your bank:

- Duly completed Form A with the tracking number
- Passport
- School admission offer letter (this can be the conditional or unconditional)
- Invoice generated via Flywire as well as any other from the school with the payment guide
- Undergraduate certificate
- Letter of an authority to debit your account (this is a letter you'd write and address your bank to debit your account of the sum of money (usually in Pounds)

Meaning of The Stages on the Application Dashboard Explained

Stage 1 – ADB_REVIEWER


This is the first stage. The reviewer carefully check for correctness of your details, verifies your account number, and confirms your uploaded documents.

Upon approval, the application is passed to the reviewer’s supervisor.

Stage 2 – ADB_SUPERVISOR

This is the second stage. The supervisor also checks the filled details and confirms the uploaded documents.

Upon approval, a 16-digit AA-number is generated and the application is forwarded to the disbursement team to approve the disbursement of the cash/transfer.

Stage 3  - ADB_DISBURSEMENT_REVIEWER

This is the last stage. The disbursement reviewer takes a final look at the application and approves the disbursement of the funds in cash or transfer.

A mail notification will also be sent to the applicant to this effect.

How to Successfully Cancel Form A Application and Re-Apply

When making a Form A application, it is advised that you exercise extreme caution. This is because – once you confirm and submit your application, you will not have an opportunity to go back to make any correction.

The only change you can make to an already-submitted application is to upload additional documents. You cannot change the account number, the bank, name, address, phone number, or whatever.

However, you cannot rule out mistakes, or in other cases, the bank you chose may simply refuse to treat your application for whatever reason.

Here’s how to successfully cancel your application and re-apply:

- Login
- Tap Form A
- Go to History
- Go to the extreme right of the application
- Click the dropdown
- Click Cancel
- Enter the reason for cancelation
- Upload the supporting document (if any)
- Upload a blank document (if none)
Submit

vta2008:


The problem with equalizing is that, that particular mode isn't on most inverters so you have to be calling technician to come equalize battery for you. My inverter usage isn't so intense and I added water only after 7 months of installation.

My batteries do produce correct fumes sha which I only notice because of the weird smell in the room where they are setup. The smell is intense during harmattan period as I tend to close the windows because of dust

Why wud you call installer to equalize for you, when you have at least 1 functioning hand and 1 head? .

2ndly the average nigerian inspite of several warnings still fails to educate himself on the workings of inverter/charge controller...heck on the workings of anything...but choose to rely on someone else to think/do for him----that is the bane of the issues we are having in this country!. automated equalized/desulphation is the best. people shud ensure they buy inverters and ccs with this function....and ensure its programmmed apprioprately.

note: kazeem doesnt know nor care to programme this. so the onus is on you to ensure you buy a device with such function. 2. to ensure its programmed accordingly

Trippledots:
Good evening guys. Please someone argued that tubular batteries do not emit gases anymore, that it was older technology issues which has been solved now. He is a coren, mnsce etc etc engineer.

Any one can corroborate his claims please?

he is wrong wrongest.

flooded batteries still emit gases, however because the average installer in clueless and inept, they usually don't program the inverter properly, so the inverter ends up sending suboptimal voltages to the battery.
flooded battery usually requires 14.5v to 14.8v for proper charging and 15.5v every 4hrs monthly. the battery will usually release gases/fumes during this equalization cos of the higher voltages sent to the battery. most un programmed inverters send only about 13.8v to 14.3v , this voltage is too low to produce any serious fumes/gases, and they also don't equalize----with this you see some flooded battery users saying they only top up water once a year , very very wrong, and such practise is irreversibly damaging the battery

zeestone99:


Seraphim is a very good brand. Tier1

Oh, i didnt know.
The name sounded local/naija issh.cherubim & seraphim.
Do you stock them or knows where to get them?

Peterlove11:


8 270watts sunpower(chinese) panels and 1 280 Neptune panel making 9 panels.
Configuration: 3S3P

ok great. @valto also recently stepped out on a limb and bought seraphim panels...against his better judgement, but he was pleasantly surprised as they presently are doing quite well too.

would be nice to compare notes after some years time as well

Peterlove11:

My panels are average panels. Had them installed Dec 2020. Total of 2440watts in pv. Still generate this. That's more than 90% instantaneous pv generation after 2yrs of use. I feel it can still do more. Maybe average panels ain't that bad as we think.

Superb!, whats the name/model of the panels. what config are you running?.
so those on a budget can look out for them.

isangjohnson:

Boss, he is asking to learn......
Properly set-up lithium pack will not have thermal runaway.
Thermal runaway is caused by either unmatched cell or wrong connection.

gloriousgbola ain't a novice, he ain't asking to learn.
am keen to hear his POV.

isangjohnson:
Again, I tested Felicity panel 350w few days ago at about 10:30am with multimeter and I got 297w which is about 85% of the stated capacity.
I'm sure it would produce more on a good sunny day.

GREAT NEWS, perhaps they hv improved,.......................... perhaps cos its still new. hitting 85% performance by 10.30am is really really superb, that means it cud easily hit 100% and more between noon and 2pm...which is the period with highest generation


wish we can get this data after 2 or 3 yrs, as that's the average time, the performance of lowend panels nose-dive

GloriousGbola:


Thermal runway nko?

do you use/ever used lithium pack?
what would cause thermal runaway in a properly setup lithium pack?

oweniwe:


zeestone99 the last time I talk say seller give 13 months warranty, una yab me tire o

This one wey be 24 months nko?

Lithium is a different breed of cat...
Its almost idiot proof and doesnt suffer from the limitations of leadacid battery, hence almost impossible for user to unconsciously damage it
3yrs is standard waranty and 5yrs extended waranty

Godliftedme:
Good morning DIYs,

Please, whats the best lead acid flooded battery for best value, good quality and at good price.
Thanks

best - rolls/surrete battery

2nd best - trojan battery

3rd best - battleborn, if you can get your hands on their flooded series.

my advice for you is go L*******
mek i off my mic, b4 fla fanboys will come for my head

Israelicc:
make the guy check whether na warranty or guarantee them tell am o because my people can use both words interchangeably.

lolz, any of them...no one will listen to him after 6 months, they will simply toss you around, and if your wahala too much, they will repackage another used/returned battery and give you...you may be lucky that one may be slightly better or worse, you insist again..they either blow you away..or clean up the original battery you returned , repackage it and give you again...........luck + persistence plays a role in all these.

with what I know about leadacid batteries, user ignorance and carelessness..............b4 I give you warranty, there must be 247 cctv video feed of the battery, usage logs of the load you put it and your charge & discharge pattern.

you cant have 2 or 4 pieces of flooded battery and put 1.5hp sumo or AC on it,, or not recharge properly and come crying warranty if the battery fails within 6 months

Drgreatone:
Thanks, any experience wit this particular inverter? Specs look great but would love a personal experience too

not used it, but deployed the powmr cc for many years and zero issues. also know someone using the 5.5kw powmr inverter for 1 year plus, zero issues. most hybrids once you protect it properly from voltage fluctuations and surges...you are good to go.

a 12v 1.5kw inverter with inbuilt CC that can handle 2kw panels, 60amps grid charging also.. all for below 200k. its a very rare combo...nuthin comes close in that class

neyosea25:
when you transfer to the wema bank account you are not charged. It's when you swap naira to dollar that you are charged. The dollar rate depends on the prevailing fx market but better than others at least for now.

ok sounding nice if so. prevailing fx cbn rate is usually about 770 or so...so guess the may be charging about 800, wch is still fair considering that other virtual cards charge over 900 now
