Okay, I do not know of this regarding growatt three operations

ojtech8291:
like phase balance that is when the three are connected in parallel they will work as a single 3phase with no effect on the individual Inverter.

Love this, folks recommend lifepo4 easily....I think it's definitely going to become obvious to many in near future.

The future is now Sir. I am a living testimony that Lifepo4 is the sure way to go. I ventured into using inverter since 2013 though I added solar panels to my set up in 2015. I must confess that my major challenge all these years have been the early failure of my LA batteries. At a time I decided never to buy new batteries from Alaba bcus they don't exceed six months of usage before they pack up. I decided to start buying fairly used batteries that were put for auction by banks which never helped either but at least served slightly longer than the brand new deep cycle LA batteries. My turnaround in Renewable materialised when I reached out to EFURO who gave me a link to a guy who have been in this forum but on the quiet side. He is based in Lokoja (Kogi) state. His core is assembling and coupling of Lithium Ion and Lipo4 cells. To cut the long story short I was able to reach him on phone and we talked at length. After explaining my plights to him he assured me that if I can take a bold step by going lithium my story will change for the better. At first I thought it was just the usual market strategy which we Nigerians are used to but after due consultations with another guy that strictly sells lithium cells in Kano his name on this forum is (Tetralogyfallot) he sells lithium cells but does not build he still referred me to the Lokoja guy. That gave me the confidence to have a firm deal with him. All these are history right now bcus as I speak he was able to build a lifepo4 bank of 6,000 watts for me. Its been two months now since I started using that battery and I must confess that my experience at the performance of that battery has been amazing. I must emphasise that owing to the high cost of brand new lifepo4 cells I was not able to go for such. He rather coupled a grade B cells for me and attached a reliable BMS to it, but to my amazement that battery is performing way above my expectation. When he did a capacity test before sending the battery to my location I discovered that he was able to pull over 400 watts continiously for over 10 hours without the battery shuting down. He attached a battery meter to the battery which helped me and is still helping me to monitor the battery without stress.

Still available

16 units of 100AH 3.2V Great Power LFP cells


@ 27,000 per cell

Are they used or brand new?

What is the Lokoja guy's contact

The way things are in Nigeria now,I would recommend a 100ah lifepo4 cells with BMS...lower cap but guarantee of at least 3years..thank me later.

Do you have specific model in mind. Where can I get it from.

earthrealm:

How many batts do you have..and what type of load do u put on it?.
Whats the size of your inverter?...

A well built lithium battery pack 100ah to 200ah will be a better option

My inverter is famicare 1000 watts, 300 Watts solar panels 100 ah battery. The loads on it 3 bulbs (3 Watts) rechargeable fan and my laptop.

Is the lithium battery thesame as the lipo4.

Keemie:

nope, li-ion batteries are different from lifepo4. @generalstingz have some for sale

Guys,

Please is there anything like a DC ceiling fan? If yes, how does it work and like how much is it sold for?

Wow! E cost o...how many inches is it?
Can it be mounted like the usual ceiling fan?
What is the maximum consumption in watts?
I can see it has a remote. Nice. But does it have the usual wall control?

Trust no one.

I encouraged a ffriend to buy 8 pieces of 300w panels+ hv hibrid inverter.
Do you know a ''reputable" installer connected the panels in a 3_2_3 config, n turned around to conclude the hybrid inverter was defective

Was it a 24v system or 48v system?

Who knows. Maybe the reputable installer has found a way to make a system inverter work as either 24v or 48v system simultaneously.

Can this type also work with AC? I know some models can be used with AC power through and an adaptor

It appears as if the Chinese are scamming people now with LifePO4 packages that are too good to be true. Bros, let's be vigilant o. Let no one use our hard-earned money to chop whatever they chop in China o.

Good evening Mr. Obimind....

I think we can actually always try to share experiences with certain type(s) of RE item technology without completely painting one type black, especially a type that has proven and is still proving reliable.

This forum deals with facts and details. And as far as this your story goes, it's completely devoid of details.

A lot of newbies and guests come in to this forum to get enlightened and its bad if they always tend to meet misleading stories

I'll go straight to my observation in your story. I strongly believe that the problems you had with your LA batteries (as far back as 2013, 2014 etc) weren't because they were LA technology. I believe they were as a result of misuse; in fact, consistent misuse.
Details that you didn't tell us here are the size of your battery bank and the load that you use. You also didn't tell us how you cycle it and how appropriately you were charging them.

We all know that LA has a big fault when it comes to maximum current you can pull from it at any time, and recommended DoD.

Imagine drawing 30ADC from a 20hr 200AH LA battery bank. Even the likes of Varta or US Trojan or Quanta would die within months.
Draw same 30A from a 200AH Li battery bank, and the battery would be smiling, and the voltage won't even dip. Drawing 30A from a 200Ah Li battery bank is even a "misuse"

I deal on both LA and Li and I always explain the Pros and Cons of each to new clients and allow them make their choice.

Folks are still using same LA, going to more than 5years and yet to change their batteries.

LA technology does not forgive abuse and misuse of any kind. Folks that understands it and are willing to abide by its "regulations" are still venturing into it happily. So, if you had consistently misused yours, don't come and dump unfounded conclusions here without facts and details of what actually happened, especially detail of your load, charging, and usage.

Just 2 months into Li technology and you're already concluding. I'll strongly advise you to study that guy very well and use it properly, otherwise you'll come back tomorrow to blame Lithium and now testify about NiCad technology...
Remember that those years, LA battery was amazing to you too until something started going wrong.

This is not for debate, as plenty have already been done, but to prevent new guys that are still trying to find their way around RE world from being mislead by your post.

Cheers

Dam5reey:


This Debate has been discussed, I don't just understand your Analysis..

I will take Felicity Lithium over your German Varta or Exide LA
LA will still be LA, if you use it at 80% DOD, it's won't last as long as Felicity.

Problem with LA is the Cycles life and DOD.

With Lithium you will still Discharge at 90% DOD without fears.. Funny enough the voltage will still be in a Good range..

HI Dam5reey...

Please, this isn't a debate at all.. Just making observation and trying to keep the thread healthy.

Now, the bolded is quite laughable. Varta has a designed lifespan of 10-15years and I've seen a man that, as at last year, his Varta batteries are 8years and still going.

I have 2 clients that have used their Ritar and Quanta for 6years 3months and 7years respectively before changing. These are facts. And yes, they don't cycle below 50% and both are using Magnum inverter

Now, who have you seen that have used Felicity lithium beyond 3years, that gave you the confidence to make the statement?

Yes, there are folks that have used Lithium even beyond 5years and counting. But felicity lithium? I strongly doubt

So please, that your bolded statement seems to come from a sentimental perspective, and that makes it a fallacy.
My problem now is not Lithium VS LeadAcid. It's specifically your statement. LA battery has proven to last very well when cycled at or above 50% DoD. As far as am concerned, there's No PROVEN record of longevity as far as felicity lithium is concerned.

Tell me that you've seen good performance with it compared to LA battery in terms of charge and discharge current, voltage stability even under heavy loads, among other; and I'll fully agree...
But until you're able to have a prove that felicity lithium has lasted even upto 5years, your statement is false, unfounded, and very misleading.

Cheers

Good morning house, please how do I get this battery to work with my rechargeable fan? What do I need to do? I connected it to the fan but it doesn't charge.

Felicity started packaging Lifepo4 cells less than 2 years ago so if you wait for a few more years you will hear that testimony. However so long as it's a good grade littium that is packed in there, it's reasonable to estimate at least 5 years absolute performance life from the cells. You don't have to wait till 5 years for that. I don't have to wait for someone to use an LA before I know that using it often at >50% dod will impact it's lifespan significantly, same calculation can easily be applied to lithium cells

That's the problem, to maintain above 50% DOD on LA, you need to at least double your capacity, which mean double the cost.. but Lifepo4 cells in Felicity are being used to 90% DOD..

Almost 2 years on Felicity and counting is a testimony already, against LA counterpart

Regarding reliability, we have this thread, please almost 2 years they were introduced, how many can you count here that has make any complain aside Capacity issue, which to me is not that bad considering the cost...

Get this straight, Maintaining Above 50%, comes at higher cost to LA user.. because it mean they will treat 200AH cell like 80AH, in order to achieve those numbers of years..

Also does those LA, Rita and Quanta, Still have Above 80% capacity Left, the answer is NO.. maybe 40% usageable..

I have LA of over 5 years too, it's still in use, but with 40% ish capacity left

As far as am concerned, Lithium technology is the best for now. I bought 2x480wh LiFeO4 used INEC battery in 2017, till today am still using them. I build a circuit that protect my battery from over discharge but New LA battery fail me after 2yrs 60% DOD but my LiFeO4 didn’t even when I discharged it 75% DOD. Beside it a proven fact that LA battery has less cycle (500-800) at 50%DOD compared to Lithium technology that has 2000 cycles at 80% DOD. Though All battery depends on maintenance and usage. Charging system is critical for both LA and Lithium technology. LA battery must not be partially charged 48hr and must not be changed above it rated current, Lithium battery decomposes at high voltage so don’t charge to maximum voltage and stored for long
