Can this inverter "speak" with the Pylontech batteries? A friend just imported some batch of Pylontech and trying to get me interested

Valto:
still available

Present sir! We shall see in za other room!

ojeysky:
Someone expressed interest in my current 200AH LFP bank some time ago but I can't seem to find the post. It should be available from next week for 400k pere, you can reach me on whatsApp.
Current status:

1. 16 by 105 cells

2. It's deepest discharge I have done is 170AH

3. Its currently at about 150cycles or less. From the picture you will see 85cycles but I installed the BMV about 3months of usage.

4. Procured early this year, around Feb/march.

5. It has a reset button incase you do a deep discharge and trip the BMS but that button no longer works. So if your BMS trips, you will need to wake it up by charging from utility source the Daly BMS does not wake up by solar charging in hybrid systems unless you are using an external CC

I have attached some pictures for your reference

Danke!

ceaser:
Sorry, I didn't get the message you quoted but I assume it's the one about the orbit fan.

Pre-dollar wàhálà, I got it for 12k. The vendor is Justcallmenuel. He's a regular on this thread.

Price and source of purchase? [quote author=ceaser post=92874628][/quote]

Excellent! It's me that I was referring to about understanding what I was reading. I will be glad to take the battery of your hand at the appointed time. Please keep me in the loop.

ojeysky:
Lol.....I built the dashboard so yes each value communicates to me, I shared it so you see the 170AH discharge at battery voltage of 25.2v



Certainly a good buy and meets the specification. Though I think it's sold at 500k now....if you are interested, mine will be available for sale in near future (when I get to do my planned upgrade)

As I saw all the beautiful charts I thought this is biblical do you understand what you are reading?
I just want to know if the battery is performing within name plate specifications and a good buy?

ojeysky:
What batteries? You mean my LFP? Battery is going fine, no issues at all. I have discharged up to 80% before and it's kicking fine. No sign of degradation of any form.

How are your batteries doing after 6 months? Any recommendation about the seller and his products?

ojeysky:
He sure made a good choice!

jovialswag:
i cant smell or taste anything. what seems to be the problem with me

COVID -19!

omotolsy:
Honestly i am surprised

I think this is one of the most truthful forum concerning the COVID-19 scenario in Nigeria.
There is massive community explosion and people are only able to talk freely because it's a faceless forum.
I have family members with loss of smell and /or taste as far back as February 2020. Never for once doubted it did not need an Italian to bring the virus to Nigeria ; Nigerians visiting China full ground!!

Because the COVID-19 response in Nigeria has been so heavily politicized and stigmatized. Unfortunately.

Investnow2017:
What strikes in all the responses is the question: WHY ARE PEOPLE HESITANT IN CALLING NCDC EVEN WHEN THEY STRONGLY SUSPECT THAT THEY MIGHT ALREADY HAVE THE CORONAVIRUS

I have watched the raging debate on why fish farming should be encouraged or discouraged and I want to state some points in an unbiased manner.
1) Profit margin in businesses differ. Even there might be differences within a specific business. Yet many market factors demand that each aspect of that business must exist for there to be a flow. E.g hospitals make more money from conducting surgeries than clinic care BUT you have to run the " Unprofitable" clinic to see patients to do the surgery on.
2) All business survive on reducing the cost of production while the keeping the value of goods produced. The profit margin in fish farming is delicate and you just have to KNOW what to fine tune without incurring losses
3) No business survive on passion only. You must make profits. However, some people are contented with thousands while others are not satisfied even with millions.
4) No business is immune to risks. Businesses fold up daily whether Pure Water business or a fish farm or a Petrol Station. Yet new ones come up and thrive where some may have failed.
5) No business is static; you must keep innovating and learning. Study-apply-learn. That cycle must continue.
6) YOU CANNOT DO ALL BUSINESS! KNOW WHAT WORKS FOR YOU AND STICK TO IT!!!!!
Selah!

I just wonder what the idle consumption of this will be?

atoleybaba:
ok...get OTC...and please if it is possible, can u take a picture of ur fish??

I will do so as soon as possible. Thanks a lot

Thanks so much for this. I want clarify the name of the drug ( antistress or fratadol?)
Thanks.
NB: I usually do not feed on the day of delivery.

atoleybaba:
first of all when you collected the fish, did u feed them immediately? If yes you made a mistake cause they just underwent stress and should have been left alone to get use to the new environment (new water) which is also another stress on it on. So best thing u could have done was left them for at least 30mins before feeding them a little (depending on how they respond) another thing was that you should have administered anti stress in their water. Now, the problem is u might have been overfeeding them thereby the water is getting polluted making them have that white patch and getting sick. They will keep dying in hundreds, infact that white patch indicate that they are sick. So what u should do is go to ur local store where you get catfish feed and drugs and ask for it or fratadol. When you get it, I don't know how big the pond u kept them is. But if it is a plastic tank, drain the pond, flush thoroughly let the water in the pond be clean,pump the water to a quarter of the pond(basically just let the water volume in the pond be low not too extremely low tho), put 2table spoon of otc in a bowl, mix with water and pour it in the pond. Let the fish swim in the treated water for like 30-40 mins then pump the water to half of ur pond and feed them little (don't overfeed) 24hrs later, drain the water completely and repeat the process. You should be fine by then.

Good morning house, I took supply of some fingerlings (2000) about 3 weeks ago and have lost about 50-60 of them. Sometimes for days no death if I don't feed them but immediately I feed them they will start dying the following day. I have changed water repeatedly, done flow through etc. Same result.
They are housed in a 16 feet by 14 feet tarpaulin pond filled to 2-3 feet level. Source of water borehole.

Recently I noticed white patches on their heads, though they remain quite active and not hanging.

I have been rearing fish in that pond on and off now for 3 years with good results at the onset. Similar thing happened with the last batch of fish I got last year and I lost close to 300 pieces before they stopped dying.
Before restocking, I allowed the pond to be empty for a month then washed with salt. Rinse out thoroughly before filling up. Used some fish feeds to encourage small algae and insect growth before putting the fish.

Please help because I am now confused. Water PH is 7.5.

The frequency (50 or 60Hz) mismatch between Gen and inverter is the commonest wahala

debeey87:
I'll appreaciate inputs based on the wealth of experience from members on this thread.

I Installed a 2kva inverter with 2 x 200amp batteries last August but its rarely used because my neighborhood is on 33kva line. But whenever we use it, it can last up to 36hrs on few light bulbs, 1 ceiling fan through the night and TV in my flat. My only concern is that whenever the battery gets low or depleted, it might take up to 16hrs or more to get it charged back up. Also whenever it is put on generator to recharge the battery, error is mostly dispayed with a long beep sound. I called the guy who installed it who mentioned smtn about the generator but when I checked, the input from the generator was more than 200v and it carries every other appliance in the house except the inverter. I have a4.5kva generator. What could likely be the cause of the error showing whenever it is on generator and is it ok for the batteries to take that long to recharge after it is depleted.

Thanks

No I don't sell. I use it for business and domestically spread over different facilities. I also started low and went up the size ladder as my need increased. I however kept all, making use of them as I see fit. I do most installations myself, including solar panel installations, as a form of relaxation. I should not mention the number and total capacity of Ccs that I have or the number of panels or batteries.! !!!
Without alternative energy, my business would have suffered terribly. Imagine 2 years without national grid power and you need power 24/7? I went the route of using generators before sense found me.

ewizard1:
Those external Bulk chargers are referred to "Dumb Chargers". They work on a simple AC - DC principle consisting of a Transformer and Diode and are advised to only be used to revive a dead battery.

Inbuilt chargers of a quality brand inverter should be different and work intelligently unlike the previous one up there. There are also intelligent "3 step" standalone chargers

Bit wait ooo, only you 9 inverters, you mean you sell them?

Sir, let me start with the fact that I am not a professional installer ot technician but I have had some experience with inverter use. At present, I have a total of Nine (9) inverters ranging from 800va 12v to 6kw 24v. Of those eight ( have inbuilt chargers, while 2 of them are Hybrid inverters in that they also have solar charging capability apart from charging through Nepa or Generator. I also have 4 external chargers deployed when I feel I need additional speed in recharging my batteries after use.
One important thing to note is that some chargers (whether inbuilt or external) are BULK chargers and do not optimally charge a lead acid batteries we commonly use. A good charger (whether external or internal) must be appropriatly sized/ big enough for the system and able to replace the power drawn from the battery as soon as possible without overcharging the battery or destroying it. It must also take the battery through at least 3 phases--bulk, absorb and float. A fourth phase may be required intermittently by some batteries called equalization phase. These type of chargers are called "intelligent" chargers and are the best type, and remember, it could be internal or external.
Sometimes to cut costs, some inverters come without a charger or a low grade one, causing issues with time for the attached batteries.

Timileyin1234:
Wetin we talk reach there be say, he say inverter dey charge battery. I com say if u don’t have external charger inverter cannot charge the battery else maybe u are using solar with it.
He com upload him own inverter and it has charger, I had to accept say inverter dey charge battery cos me I never see inverter whey charge battery without external charger.
As I com see ur own external charger now, e mean say wetin I know b4 no b fluke. That is my external charger

olaolu11:
It is adequate today, but tomorrow? She has a fridge which she will want to power tomorrow when she begins to enjoy solar. We are only trying to avoid purchase of another inverter in the future.

True BUT the issue of "you better do better" is what chases some people away from solar energy thinking it's too expensive. People buy and use I PASS MY NEIGHBORS Gen readily just to power some things in the house and not use generator to power their fridge etc ever or buy a bigger generator. Must someone upgrade? No!! Or because of possible upgrade in the future allow Heat to suffer my head now? No again!!
I sincerely think she should and could use her proposed system as it is. If she so wishes to upgrade then let her ask for advice.
My view only. Half cooked meal is better than none.

Oga stop talking what you don't know. Coronavirus has been killing both young and old, has nothing to do with age.
https://nypost.com/2020/03/16/soccer-coach-dies-from-coronavirus-at-age-21/
That coach was 21 years old, and Coronavirus killed him. There are hundreds of young healthy people the virus has killed. You people said it doesn't affect blacks, but today that is fake info too, blacks are already dying from it. You people said our hot weather, smh, another fake info because other HOT African countries like ours are starting to get Coronavirus cases. Some of you also said it only kills people with weak immune system, which is another hogwash, because the virus has killed healthy people, the virus has killed old and young, male and female, patients and doctors, it has killed rich and poor, elites and commoners and maybe soon, it will be killing presidents.

Concerning point 1 was my issue. While I fully understand the reset button scenario, my worry remained. How can my Cc charge at all if no power gets to it?
Possibly that was why only grid might be successful to wake it up on the event of a shutdown.

ojeysky:
There are 2 things here:

1. Low voltage protect of the BMS, if and when this happens the BMS shutdown power from going out of the battery hence your inverter won't even come on. The idea is for you not to get to that stage by doing point 2 below, but if it happens, the reset button or hoping that a high solar current will be sufficient to wake up the BMS are the options

2. Voltage cut-off by the inverter, if this happens then no issues as the inverter is what has stopped output hence your battery still have juice in it and will be ready to receive charge whenever it comes up. I recommend this and currently have mine set to 24v.... unfortunately that is the highest cut-off voltage that I can set on my inverter (and I think this is applicable to most inverters).

Do you MANUALLY have to reset the BMS? I presume a low voltage cutoff means the system shuts down due to battery being disconnected to inverter. In an Axpert type of inverter system, the inbuilt CC depends on battery being available to power on and I connot but imagine the possibility that the sun will be shining and my system will be sitting dead while I am at work. Or is there something I am missing here

ojeysky:
No it can't be connected in series. It can be powered by solar if you can get high amps from it. If the BMS trips due to low battery, don't reset the BMS until you have reasonable hervest (at least 5 to 10A), am off-grid and that's what I do everytime I have had a BMS trip. That said, it's better to avoid getting that low in the first place :-)

zeestone99:
Congrats man. I will send my cable underground.

Abi o! Or do remote tapping!!

solasola:
the talk has spoken itself. My advice is that you need patience and never rush. We are waiting for your analysis to cater for an off-grid scenerio , tell us the battery bank needed, the dod%, inverter choice, cc choices, etal.
We are waiting to learn from your wealth of experience.

Kai, e go hard for our friend o. This will involve some little THINKING!

See well informed analysis, the genius has spoken! Everybody bow down for the king!!!

(Maybe he will allow the thread to rest now, and we can have some peace, otherwise nah to organize some lytic cocktail with a dash of propofol for him )

Chest beating afonja.. empty vessel.. Because we are on Nairaland, some people will be claiming all what not.

Because it is Niyi now, none of u want to think with your brains, only with ur anus.. my opinion hasn’t changed. 3 inverter air conditioners, an inverter washing machine, an inverter microwave, TVs on energy saving mode, all bulbs as leds and u are down to 3000-5000 watts instantaneous at most..

Why then does anyone need 19k watts??

Uninformed fools

Eeya. It's so sad.
Funny enough you could turn out to be one of my residents, that's how small the world could be. After all NL is a world of anonymity.

But you've been a great disappointment to the medical profession with your depositions.

Except those that may have been patient enough to decipher thru some of my subtleties on NL, not many will ever think that I have attained the highest level in the medical profession (on the clinical side of course). Yet I never tried to brag about it nor rub it in the faces of anyone.

Truly, as Barezzi opined, people in the west mostly mind their business. Such outlooks about life also come from experience and exposure, two vital things that is apparently lacking in your make up.

If you truly are a doc as earlier alleged, then I honestly think you need to do a deep introspect to know if medicine was really your calling.

I am thinking a diagnosis of Tourette syndrome with Colprolalia will be apt to describe his condition. I really doubt if he ever entered any medical school but in case he ever had any form of medical training, I just hope his verbal diarrhea will not manifest in a viva. On day, truth will truly be told and then prostration and ejowo sirs will follow.

Classsss! Pls let us not digress. We are still in d class, let us learn.

On point my brother! There are some discordant flash in the pan, sitting room critics that derive peculiar pleasure by being nasty. There is no iota of sense in you yabbing anybody in your bid to instruct them. Moreover, you are not anybody 's father and also, the money no be your own;
so why the incessant vitriolic diatribes?
Nairaland no do well at all. There should have been civil sense age limits for some threads, walahi!

Typo! It's 24v/400amp.

Thanks for the info.

ojeysky:
For now the major performance I noticed is the ability to accept amps/power surges. For instance, my washing machine on startup does some few min of over 1.4kw draw (think it's the heater), my lead acid was unable to cope even when the battery is full but LFP takes it without stress. Capacity wise I have done some rough test but yet to do actual (getting bmv soon) but I don't expect much surprises as the 200A LFP serves the same load (or more) for similar duration that my 300A lead did at corresponding DOD.
For me the big deal in LFP performance will be whether it's capacity remains the same in 3 to 5 years time (after many cycles)


Do you mean as 48v/200A? with over 2 years of usage, are you loosing capacity on it yet? and at what DoD have you been maintaining.

That said, If I have opportunity to get more lithium, I will rather go DIY by procuring the cells, slamming a BMS on it. That way I am able to easily do periodic individual cell check(even though I know that's the work of the BMS) and will also save some cash. Found some good deals on AliExpress but shipping is the problem, if anyone knows a reliable china-nigeria freight forwarder please share.

ojeysky:
LFP Vs Lead Acid. You going lithium? If you have a 24v set-up, Don't expect voltage to reach the 24v and infact if your lithium get to that level then you are already at almost 90% DoD. Most of the lithium juice is within 3.2 and 3.4v (per cell)

After using for a few weeks, is your present LFP setup performance actually DOUBLE the Lead Acid 300amp 24v performance? I have 4 Monbat 200amps batteries (connected as 24v/200amp) that have been in serious use for 28months and
I am gathering info as I consider replacement soon
