What will I do my inverter spoiled during the rain every time thunder strike my own trip off
And will not come on again

Please contact a competent person to fix a good earthing for you.
Buy a good stabilizer and place it in between the inverter and the main to take of nepa over current madness, if you're running a grid tied system. I guess prag/ servo is expensive depending on the capacity. My cousin's transformer based 48v 3.5kva felicity inverter was damaged by nepa a few days ago. Nothing concern me with nepa..... Na only lightning I know.
In this raining season, I can't just imagine myself putting off my system whenever it rains. The inconveniences alone.....

dollarnaira:
Some inverters will act otherwise.

Can you give practical review on this for lesson purpose?
All the inverters I've seen tripped off when they are overloaded them.

dollarnaira:
Hope you checked enough positive review?
Plus 4 important protections:
* Lightning
* Short circuit
* Overload
* Temperature

Na the above dey finish inverter patapata

Number is user defined.
My inverter may escape lightning hit due to good earthing and other factors.
Another person with the same inverter may not escape it due to poor earthing and other factors.

TechGeek777:
Money is water to some people, 75kwh is no joke, enjoy your setup bro.

Snap your MCCB and enclosure box for clearer view

Jonescosmos don vex again.

jonescosmos:
How my set up looks now.

What happened to your former batteries?

olopan:
TECHLAND SHOULD HAVE SOME

Thanks sir

I need original Canadian panels to be shipped to Uyo.
Who has a link to where I can get the original one?
Fouani store doesn't have 580w at the moment?

obinna37:
is for friend that went to china,he wants to buy it for personal use,he is seeking for my opinion,he doesn't know much about lithium battery

Can you drop the datasheet of the battery pack?
How much did they tell him

dollarnaira:
1.25m now an entry level and a budget set up for a 12v. Evidence of bad economy laced with inflation. Omo 12v set up now a luxury and unaffordable. How did we get here?

Most reason most of us that started this journey a few years ago should take good care of our investment and thank God for the foresight.
Most family can't even afford fresh tomatoes now in the market,

It's getting worse by the day...........

obinna37:
Good morning all,my friend that went to china he sent picture of this battery,if he s should buy it

What actually do you want to find out?
We only see the picture of the package and we don't know the quality of cells inside.
You may furnish us with the details of the battery pack and let's work on it.

Nutridelfarms:
Good day people, I intend to install a 5/6kva hybrid inverter. I have attached the quotation received from my installer. Just wanted to get remark about the adequacy and reasonableness of this quotation from knowledgeable folks and experts in the house. I welcome any advice, suggestions, comments.
Is it advisable to combine a particular brand of inverter (eg GOspower) with a totally different brand of lithium battery (MARSTEK)? While my installer quoted 1.7M for the battery, I did some research and found the contact of the main dealer of the battery in Nigeria. I could get it for 1.2M directly from their office in Ogba. However, the hybrid inverter of the same brand (MARSTEK) cost 1.2M and they're not willing to reduce the price. They advise buying their inverter and battery together but completely optional with a caveat though - that combining my battery with a different brand of the inverter voids my warranty (10 years), as they cannot vouch for the performance of the inverter I would use if it's not from them or one of brands they've tested. They sent me a list of other brands that their battery is compatible with, however, the prices are ridiculously high compared to theirs.

Is it worth taking the risk to go ahead with the quotation given to me by my installer? I don't just think I want to buy an inverter of over 1.2M. It's a lot mehn.

The company will give you 10 years warranty if you buy the 5kwh lithium battery and the inverter together, right?
Does it mean there will be no warranty at all if you decide to buy only the inverter?
An average warranty most companies give to inverter is 2 years. If that company accept to give 10 years warranty for ithe nverter and the battery, then I'm assuming that the battery warranty might be 7-8 years.
Then note that any lifepo4 battery manufacturer that gives you 5 years warranty and above on its battery MUST be batched and matched grade A cells used in coupling the pack and it will NEVER be in the price range you' have mentioned.
Maximum warranty they give in quality grade B cells coupling battery pack is 3 years.
You can drop the datasheet of the lithium battery and let's see the information.

Malevonent:
Whats the cost difference like between the matched and batched eve and normal eve cells?.

U still buy from selina

About 15 to 20% higher.

No

TCD:
Are there specific felicity models with Gade A cells and those with Gade B cells?

How does one tell the difference?

Jonescosmos has given you the company contact number already.
I strongly believe that whoever will receive your call will be someone that has been in the system. Tell them that you want battery pack build with the batched/matched grade A cells with manufacture's test report.
I'm sure they have it but the price might be 15 - 20% higher than their usual Grade B battery pack.
How to differentiate?
Request for EDMS from them and connect the bms to your PC monitor that will enable you to view the charging and discharging of individual
cells using the datasheet/recommended C rate. Pay more attention to the upper and the lower knees as I earlier explained in my post.
Goodluck

Dam5reey1:
Las Las most can't tell difference once it's inside pack, no matter how you preach this Grade A gospel.

Let's just leave the matter and move on with, people will get what so ever they paid for.

Home storage DIY users can always top balance their cells and not have issues, for a long time with Good smart active balancer in place, also they are not heavy users, hence Grade A is useless.

I vividly understood your points but we need to constantly enlighten and pass the knowledge to those who do not have the
privilege information that we have.
Money is very hard to get now, even the rich men are also feeling the heat. Getting what we pay for should make us happy and honesty is key to business, especially when there is no warranty or the warranty is not possible to execute.
Nigerians should not always be taken for granted. I challenged and I want the Chinese aftermarket (grey market) Lifepo4 Cell/Battery Vendors to stop their fraudulent activities. I will keep exposing them here. Some of them are silent readers here.
The Grade B stamped on the QR code by EVE is easily removed with a lazer and reprinted Grade A on it. We've seen video evidence of vendors doing this. That's why all of them are selling grade A cells
SINCERE companies like batteryhookup, Sunfunkits, Ezeal etc selling batched and matched grade A cells will email the manufacturer's test report to you free before you ship out your order.
YES, diy users won't have much issue on it but what about people that are buying ready to go battery?
Most of these people are heavy users.....

mctfopt:
Let's just assume things for a moment what if a seller sends you a faked test report how can you tell?

Fake test reports are extremely easy to verify. Simply email the test reports to EV for verification.
Between 24-48 hours, you will receive a feedback.
I verified test reports for 280ah matched and batched Grade A Ev cells a few weeks ago and they said are all legit.
I'm expecting 105ah batched and matched grade A cells with their test reports next week
Tuesday. Once I receive them, I'll email the test reports to EV for verification.
EV company is too big for the cells resellers to bribe and the company doesn't joke with it standards.
The company has been receiving negative complains about the dubious activities of the gray market cells dealers. That was why Ev decided (about two years ago) to stamp B on top of the cell qr code in all its rejected cells that were not up to the automotive standards. The
resellers would replace the entire qr codes with the fake ones and sell them as Grade A+.
These are all fake market strategies. There is
nothing like grade A+ or grade B-.
You can peel off the black cover, clean and wipe all the glue off with rubbing alcohol gently to find out the truth.
Finally, capacity is not a good measure of a cell, nor is it the primary reason why cells are grade A.

jonescosmos:
People ended up buying Lithium Batteries from random places at a too good to be through prices.

I personally discovered that some sellers harvest cells and replace with lesser capacity cells (I kid you not, fear Alaba Market People)
We often times look at China as a major source of fake products. Truth is, those guys actually have Quality Control Department that works. But our people will always find a way to infiltrate facilities.

Any Felicity Product you see with Internal defects or cell mismatch and etc must have been tampered after it left factory.

I can show you my chats with Felicity Engineers, where they give a go ahead to open up a product and show them what I found inside and through that most times they have confirmed to me genuine components and fakes.

See this new 25KW that was recently brought into the market, I have made verification from Felicity about the cells and they said its packaged with REPT Cells and this particular 500A Grade A >8000 cycle cell is not yet in the market because REPT must satisfy OEM factories contracts before selling to open markets, let's wait a few months and see what cells you will see from the Alaba Market Sources.

Try to visit Felicity service centers you will understand better.

When buying felicity products, buy from them directly, e get why

I really thought the community was beyond this but looks like we're right back to where we were two years ago.
I just decided to keep a simple decision about lifepo4 cells purchase in China.
1. If I need batched and matched grade A cells, you MUST attach FREE test reports of each cell with 5 years warranty or more.
I'm very happy with EV for not compromising on its standard. Dubious gray market cell sellers are afraid to issue out their fake test reports because they don't want to be exposed when we mail the reports to EV for verification.
2. If I need grade B cells, then we discuss in details about the quality. If the quality test is up to the standard, I'll keep the patronage.

TCD:
Chief what's your experience so far with your felicity lithium batteries? Do you recommend? I'm reading alot of complaints

Felicity honours warranty....... There is room for refunds if it doesn't meet up with what is being advertised.
You may test it by using the manufacturer recommended charge and discharge parameters via its datasheet. You may also monitor the performance of the individual cells via the bms pc monitor. Batched and matched Grade A cells will remain balance and work together at the upper knees of 57.6v while charging at the recommended C rate and the same thing with the lower knees of 44.4v while discharging at the recommended C rate.
Grade B cells will not work together from the bottom to the top. Runner cell will take a lead on the upper knees and hit full voltage cutoff before reaching the manufacturer recommended max voltage and the same thing will happen at the lower knees while discharging.
SUBMISSION: We should not always rely on misleading stickers pasted on products.
Physical assessment and practical test will
also reveal the hidden truth.

jonescosmos:
I have no complaints what so ever.
I will do a take apart video soon to disclose what cells and other components are inside those beasts of batteries.

People who have complaints probably did wrong installations or didn't buy genuine felicity products.

I think his findings here were centered on the type/quality of cells used by Felicity and not the connection as perceived.
Actually, there have been negative reviews about some of its batteries and I've seen some interior pictures of LPBF model of its 15kwh battery bank.
Apart from the poor performance of the cells not measuring up to the advertised standard, the owner also complained about the quality
of cells used as he was carrying out physical assessment.
However, there were positive reviews about the LPBA model, except one person that complained about its bms not allowing full charge.

capnies:
please where in port harcourt can I get good tubular battery

When you say good tubular battery, are you referring to a product like Quanta battery?
Putting budget range may help to know the quality of battery to recommend.
You may even be lucky to get lifepo4 battery for similar budget, especially if the owner needs money to add and clear his goods at the port

Hybrid600:
Felicity dey vex o! Omo!

I am really happy that they are bringing out more bigger cells with AH that one could use for a single battery bank.
Parallel battery bank occupy more space and makes people spend more in terms of accessories.
There is 628ah Eve Matched/Batched Grade A Cell with 8000 cycle and test report for each cell. One can verify it by emailing the test reports to Eve. It takes them a day or two to response.
I verified reports for 280ah Matched/Batched Grade A Eve Cells a few weeks ago.

AdexAyanfe:
Please gurus in the house, I have 2 questions.
1. I'm trying to build a lithium battery pack. Can I use button head 18650 lithium batteries, or only flat heads are acceptable?

2. Where can I source good lithium battery please? I'm based in Ilorin.
@Valto @isangjohnson @everyone

I think there is someone in this forum that sells lithium ion cells

Damlesky:
Here are some details about the product.

How much?

For the number 2 question, are you looking for lithium ion or lithium phosphate?

adrusa:
Same here. I bought a battery from him based on the recommendation of a friend who has had one of his batteries for about 2 years or more. The battery I bought came with JBD BMS which seems to have occasional loss of Bluetooth connection. However, I do not consider this a serious issue and I did not even contact @Valto to complain. I think his batteries are good. He didn't make the BMS and it is likely that one may just have a dud. This is not something to attack him for.

I bought 100A 16S jbd from him when he was in the hospital. The bms app wasn't working. I later called him and complain. He gave me a discount when I picked another one. I'm not even using the first bms again.
Business is all about understanding..

AllyPolly:
I should have reached out to you again when you have not sounded as if you care about what's happening? Not even a single word of apology was rendered about the awful experience!

Is it an abomination for you to check out on a customer whose last conversation with you states the issue persists?

If not that my installer is good and calm, he was the only person following up on the matter. He was also really disappointed on the turnout of event.

Okay, now, I'm saying it clearly: The issue persists and I need a resolution to this matter.
2.8M isn't something to gamble with. Thank you!

Please, bear with him. He's going to fix the issue.

adrusa:
It is a lot easier to do than you think. Once you get the hang of it, which is very easy to do, it becomes a part of you. And the reward is sweet. I don't buy any smart thing if I can not "flash it" and put it completely under my control. I have Sonoff, Victron, Axpert, Wemo, Emporia, ANT BMS, JK-BMS, JBD BMS, Felicity, Easun products, etc and I talk to them locally without using the manufacturers' apps or internet connection.

The last time I checked, you were still trying to get the communication aspect done on your Felicity inverter.
Were you able to do it at last? I want to even replace my 5kw Felicity inverter and get another product with an easy/flexible communication protocol.
I'll appreciate if you can contact me through my phone number here.

princely009:
Omo...these steep roofs(send down the rain roofs) are really bad for solar generation.
These past few weeks, my battery has barely charged past 45 to 50%. Something that gets to 100% b4 2pm before now. It's seems the sun direction has changed. Now it currently favours North on my roof while my panels are facing south.
The solution now is an expensive solution. I need to install new panels facing north and buy a new charge controller and cables

By the way, who sells growatt 120A charge controller. I need one for this upgrade.

Between , hope my lithium battery not charging to 100% daily won't affect it?.

People with steep roof tilt their panels to their choice of angle for efficiency. The bad weather conditions you experienced is affecting all of us in the south. This is the time of management and those that put about two days head rooms in their battery bank may not feel much impact.
Partial charging doen NOT have effect on lithium battery. It only affects lead acid battery.
