Why not just invest in liFePo batteries?... I'm just saying tho.

It ticks the safety box that you fear.

Its in a remote location and I don't to test run it in a place uninhabited incase of fire

Isn't the self-combustion thingy more common with Li-ion batteries?
I have read from different sources that Lifepo4 doesn't do that.

Yes I believe it's a Li-ion battery syndrome. I read Lifpo4 are quite safe. Here is a video demonstration of a self bursted lifpo4:

Okay I don't have that option in mine so I had to set manually. You may want to check that bulk voltage of yours as it may be under charging the cells maybe you push your bulk to 14.6. My system cells has a charge up to 3.65 per cell (Which is 29.2) when I kept both float and bulk at 28.8 I experienced occasional spikes to 29.1 but things were stable with current settings.

The BMS overviltage alarm trips and beeps at around 14.5v and it switches off the charging and the battery output to the inverter.

I think to be doubly sure, I'll measure the output voltage of the provided AC charger of the battery.

Sorry that was a typo I meant to write 14.3. Original post updated

You should be able to provide technical support especially here, ensure you provide technical details and support, also learn more about a product.

I walked into a solar shop, sales girl told me they don't have battery charger, that is on the shelf

Day 1 with lifpo4.

My night loads was the same (or even more because I did put on my 1.5hp GenPal for about 20min) and I still have 26v reading on my display.
It outperformed my lead acid significantly as I will be at 24.5v if it were my 300AH lead acid.

In other to reduce the long speech I think the attached picture should summarize the difference between lead acid and lifpo4 experience and you may see my signature for more detail log reference. Perhaps it's just a coincidence but it seem my system efficiency was better. Including temperature of inverter.

I am wowed! with just a day performance that I have experienced with this thing and I am wondering if this will continue in months to come. Whether 4 quanta will have given me the same experience is what I don't know but one thing I know is that the weight and space of a quanta alone na worry.

How I got mine: Meet with a guy remotely who deals in lithium. So he coupled for me 16 EVE LF105 to make 24V 5.4kwh (actually nominal is 25.6 as each cell is 3.2V) and ofcourse it comes with a BMS and voltage indicator.

Price: 450k - I checked price of the cells and estimate cost of materials he used to conclude that it was a fair price.

His contact is on the battery sticker but you may also PM me if you like to have his details. He was quite professional with me though I have not meet him physically before but took the risk.

great news, seems i would try it as well. to replace a disaapointing 12v 200ah quanta, that barely lasts the night on a simple load of 40w to 60w, in this dry season.
since a 12v 200ah batt is abt 2.4kwh, i guess i would be ok with a 1.4kwh LIPO4 battery?. i wonder how much that would be

But the guy intentionally punctured it na...and the cell was not inside the battery pack.
It did not burst into flames on its own...In fact, the thing only released gases (which I know may be dangerous sha)

But why would I intentionally rough handle something I sold a kidney to buy up to the point of puncturing it like that?

My LFP doesn't have alarm or display but I think the BMS is doing a great job. Though not yet connected to solar yet due to current resident but with the ac charger is rated 14.6v 20a.

The charger trips off at 14.4v and I noticed battery never goes above14.4v. So I'm guessing the BMS trips of charging once it gets to 14.4v.

This is strange, hope it's not fake. There was a time I dreamt of purchasing a quanta

You can try a 12v 100AH lifpo4 which is 1.35kwh. The guy sells that at 110k you can reach him via his number.

It was to demonstrate that it cannot burst into flames

So that you can be rest assured that selling that kidney was safe enough

What's the ballpark figure of 5 modules, Pylontech US3000B?

desiji:
Sorry but it is if you want all this completely finished product with Warranty, I am using the Pylontech US20000 Plus that cost from my end 1200€ i am now upgrading to 2x us2000plus plus 1x us3000plus which when you change to Naira cost like the 2 Kidneys. but i have the absolute warranty i have testeted the 1 us2000plus for over one year i have about 267 circles on it i can add the others because it is modular

Your 1.4kwh is around 100ah to 120ah 12volt.

I got the 12v 120ah for 155k.
12v 60ah for 80k.

Yeah, I too guessed 14.4v as the safe limit which is why I initially programmed the bulk to 14.5v before it now starts tripping overvootage on me. I will try reprogramming to 14.2v and see how it goes.

The 12v 60ah LFP I own doesn't seem to have an overvoltage alarm cos it has gotten to 14.5v (never past it) on many occasions without any alarm.

Oh, this is another fair and more competitive price. Although I will watch your experience with yours, being 9ja made, to see how his product goes before taking the leap

Please at what prices bro?

I will drop the price once available

I agree as you are new too.

Sorry i was not online yesterday night. The Pylontechs us300plus cost like 1500€ at my end i am currently handling with them if they can cut the price the two Us2000plus i bought they gave a discount and i guess if you are buying more something would be done, funny enough the us3000plus is cheaper in S.A but i know no shipper from there and trusting somebody with such amount , but i can qualitative say the pylontechs are good for the money ,till now not disappointed and doing its duty like a soldier
