Hi guys,

Pls anbody knows if fangpusun charge controller can actually handle lithium battery.

It's on the manual, but I want to be sure oh since the manual is a copy of victron's own.

Certainly since it has adjustable settings

mctfopt:


I see these batteries in industrial application, it is great to see someone use it in a domestic setting. Good job here. These batteries have the right to cost an arm and a leg plus two eyes

A popular marketer was marketing this product last year

https://www.nairaland.com/390522/solar-energy-complement-fta/602#83420592

I went through the link. The marketer was selling 6 pieces of the battery for 130k. If you factor in inflation and other things, it should now be about 200k. It is quite affordable...abi am i not getting something right?

Bros 1 2v @130k will be about 1.6m for 24v 2000AH setup.

earthrealm:


Yes they are,
8 x 250w near owerri.
12 x 250w in benin city.
Bulk purchase is encouraged with a slight discount, as seller would prefer dealing with 1 or 2 persons

I am interested in getting 1 or 2 pieces of the Flames brand - the ones you said were recently installed.

Can we create a group (with other interested persons) so that we can pool funds and buy at once?

I am in Lagos

Very pricey, indeed, for just batteries. But can one do 12v for starters? And does it use the normal inverter-panel models?

BeardedTraveler:


OK. Thanks. Which of these 2 is urs though? I'm trying to figure out if there's any real difference between the 2 because of the difference in price.

The first pic, however both look the same, apart from the efficiency sticker on the first.

Lemme let you in on a lil secret.
The single reason aparently same ac have different prices is the evaporator/condenser, expensive models come with copper, which resists corrosion, while cheaper variants hv the evaporator made with an aluminum alloy, wch will corrode and leak within 5 yrs, especially if refilled or left unused for long periods

24 x 130k is 3.1m for a 48v 2000ah bank.
Incountry price of 48v 600ah lifepo4 bank is Abt 3m.
40 x 12v 200ah quanta = 48v 2000ah is abt 6m
I would take a 48v 2000ah lead acid bank over 48v 600ah lithuims.

Wish the batts came in 6v 2000ah, would be a lot easier and affordable for a 48v bank owner.
I wonder the price of 2v 1000ah

This should give an idea!

Although there are way cheaper brands in alaba for less than 100k

Are there Inverters that work work this or it has to be accumulated to at least 12v?

If it's 6 for 130k, I'll be using it

Glad others have answered this question.

IYGEAL:

The lowest battery system for most inverter is 12v, meaning you'll need at least 6 of this battery (6*2=12) to make this happen.

Are they pure sine wave?

Pure sine wave sir

ceaser:


I believe your long courtship with the Zenith lead batteries boils down to usage. When I was "lead acid", the low discharge cut off for the batteries were 12.1v, but I wasn't impressed with the two years plus I got before I felt they needed replacement, although I admit they were not "high premium" brands.

An AC gate opener (idle consumption of 3 watts+6 watts idle of the 300 watts inverter) I used always ran down the two pieces 12v 12ah batteries by morning if the sun does not come up as early as 8am and within 6 months the batteries usually needed to be replaced. The solution then was to switch off the inverter at night and back on in the morning, which is not always done since I'm away for weeks at a time. But ever since I changed to a DC gate opener on two pieces 12v 7ah batteries 10 months ago, the headache is no more.

Your 12 pieces 260ah lead acid battery bank is massive, so I won't argue if you say you don't go below 12.5v DoD in most cases within the 8 year period. This undoubtedly will earn you more years of beauty from the battery. The popular consensus here is that lead does not forgive too much and too frequent high DoD at all, but lithium gives you more at higher and more frequent DoD. One of my lithium pack has rarely gone below 13.0v by morning in the last 4 months even though the LVD is set at 12.3v. If it continues like that, I see myself getting 12 years use out of it.



Sonnes what?... Sounds like something out of Hitler's Germany I almost bit my tongue pronouncing that. Woah, massive beasts by the way; literarily, "I kill drum for you" (I doff my hat for you). Abeg which of your kidneys did it cost you? Just wondering ni o

With this renewed acquisition and rekindled romance, I don't see Mr GeorgeD1 courting lithium for probably the next 15 years, a time majority of us here as AE enthusiasts might already be using lithium-powered electric cars. The only reason he might be forced to use lithium at that time will be in his own electric car. Lolz.

i tend to agree with the dod bit as part of a wider range of factors that helped prolong the life of my zenith batteries.
right from day one, my battery lvd was set at 48v cut-off. This translates to 12v for each of the 12 batteries in the pack.
and for the almost 8yrs they were in service, i can count on my fingers the number of times inverter tripped due to
low battery voltage (it rarely does).
in my experience, i have come to see lead acid as a "if you do me well, i will pay you back handsomely" kind of battery
chemistry. provided you don't abuse them, they are ready to give their life, their all for you. and the zeniths seem to have
done this in grand style in my own case.

as for lithium, the good news is that i wouldn't be waiting another 15yrs before i jump on the bandwagon. i know the
value of keeping abreast with technology so i intend doing a little experimenting in that space. maybe a little lithium
bank side-by-side the massive lead acids might not be out of place. but first i would need a little time to recover
from this huge dent the sonnenscheins have inflicted on my balance sheet.

odimbannamdi:

Most 12v inverters comes with 20/30A charging, so charging 12v 2000AH will require a number of multiple external chargers. Some of those external chargers do up to 70A or more @12v. Ultimately I won't think of trying it for 12v even if am gifted, I can make an attempt with 24v but it won't be optimal for a solar setup unless external charging is involved.

you're right bro, but i didn't get mine from him. i guess other guys (probably not on this forum) saw the great bargain
and quickly grabbed them. by the time i made contact, they were long gone.

so, yes. those batteries are actually industrial type off-grid lead acid batteries (if you check the specs i posted earlier on).
they are the type you find at telecoms base stations, bank ups rooms, remote sites for weather monitoring equipment, etc
given their size and weight, they are an "install and forget" kind of investment. nobody expects to be changing out such
massive size of batteries every two, three or five years. it's really back-breaking work aside the financial outflow.
how they suddenly became available to the public as "project left over" is still a puzzle i'm yet to resolve...

We've not factored in waybill as well, you will probably need a truck to move 48v 2000AH and also a large room space while with 3.5m max I can have a 48v 1000AH LFP in my car trunk

You have them in your house already so leave the detective work for batman. Congratulations on the upgrade though.

This type of battery connection always confuses me when I see it. Each battery has 6 terminals, how does that work?
Do you have a drawing for it?

GeorgeD1:
in conclusion, while i'm reluctant to change a winning team (obviously lead-acid has served me well),
i'm open to new technology and definitely lithium will have a major part to play going forward as a
next steps towards acquiring even more storage as i continue adding power guzzling creature
comfort equipment to the house.

If it's 6 for 130k, I'll be using it

Terminals on the battery relate to the individual cells that make it up. Each comes with their positive & negative terminal which you have to parallel to get the full AH as printed on the battery. Number of cells is determined by the amount of AH on offer.

From here you connect in series to make up your desired bank voltage. Remember the batteries are nominal 2v. Quite easy to get around though.

Especially base stations and switch. It's truly "install and forget". Congratulations, you probably won't be buying battery for the next decade or more.

One fear I had about this kind of setup is if a few of the batteries developed faults. 1. They are rare batteries, not easy to come by and 2. The cost of replacement. That is one of the advantages of 12v systems in parallel. A bad battery will not immobilize the entire system.

With my experience with Lead Acid and LFP, I will take 600AH LFP over 2000AH Lead Acid. I don't know the characteristics of this particular battery, but a 2000AH LAB does not give you 2000AH, maybe about 1000AH or a little more if your load is light.

earthrealm:

It's c10 lead acid I think it may give close to the spec since one won't be doing up to 0.1C discharge concurrent; a typical household won't be pulling more than 200A @48v consistently. I think the battery gives 3500cycle at 50% so it's not the normal lead acid out there.

Good day all. I recently got two 220AH Luminous NRGT batteries (Tall Tubular) and my inverter indicates the batteries are full. When measured with voltmeter without load they jointly read 25.6V.

But when I put load on the inverter, and put on like 5 led bulbs, the volmeter immediately drops to 24.4V. I'm surprised in the sudden drop in voltage.

Is this normal or there is something wrong with the batteries.

Inverter is Luminous Hybrid also bought newly
