@nonoski.
1. Verify that the charge controller charge voltage settings are in line with luminous batt, i once made an error after a battery swap of not changing the cc battery voltage charge settings.

2. The HA02 battery balancer may be a culprit, i would suggest you try bus bars or another brand of balancers.

3. Since the housr is relatively empty all year round. Consider have a 1kw load, say water heater or even fridge run for some time weekly or so. To draw the battery down periodically

1. Charge Controller is victron blue solar
Setting is 54.4v for float and 58.6v for absorb

Inverter setting is 54.8 for flair and 58.7v for absorb.

The batteries are mostly charged by solar

Attached is a screenshot as at this morning.
There was lite all throu the nite so the batteries were on float.

2. I have been using HA02 for years maybe I should try another balancer as u suggested.

3. Ok will consider that. I have several fridges in the house will connect it to a timer switch.

I bought those useless luminous batteries myself from Simba in Lagos and had them shipped to Anambra.

I was so disappointed with the batteries when I saw each of them drop to 9v during load testing.

I didn't bother calling the Simba even duh they muted warranty when I was paying for them but I know how warranties work in Nigeria so I have made up my mind to discard the batteries. I don't even have flight money to spare to go to Lagos.

My problem now is which batteries do I go for?

I have been researching about the claim that having batteries on float almost all the tym is not good for batteries
Even duh it discharges every nite to about 15% DOD

Lithium batteries are out of my option coz it's in a remote location and indoors wouldn't want to burn down my inheritance

Sorry for the loss... It's a very big one.

Though since this Luminous Blue came out, I've only been hearing bad reviews for it. Their yellow mode was a little better.
As a matter of fact, a Solar Company here in Eket carried out a capacity test on the Luminous blue and got about 87%.... Very poor I must say.

I also know a boutique that is using 1.5KVA/24V Sukam falcon plus with the Luminous blue. Loads are just the lights. No fan sef, just lights and they have never drained it to alarm level. After 9 months, another story... And two or three other negative feedbacks from users.
I've been discouraging people from going for this Blue model

I believe it's a factory issue. Same thing that happened to PRAG battery sometime. After they modified their battery and it started have early failures.

I might not be able to suggest the best battery, because I've not actually used or installed all. But Over 5 years now, the two batteries I can vouch for are Quanta and Safepower.... Both are Indian

From Chinese angle, I've also come to trust Mpower (distributed by AirWave Ltd)... I do use them for clients on low budget.

All the aforementioned are from my personal perspective.

As for batteries always being on float charge posing a problem, to me it's a fallacy. As long as the float voltage of the charging source (Inverter or PV) is within the recommended voltage of the battery manufacturer. For example, almost all inverters have a default float voltage of 13.7/13.8V. But Quanta strictly recommends 13.5V as the float voltage. So question is what happens when you have Quanta batteries that are being subjected to constant float voltage of 13.8V?
These days, people just randomly choose Inverter and batteries without any form of regards to conformity and compatibility.

Finally, looking at your setup, it can be seen that your battery arrangement calls for long battery interconnecting links at some point. I hope ALL the links are same length and same size. Not that some would be short and others long...

As for the Battery balancer, if it's HA02, then I believe it shouldn't be a problem. Unless it's all those Sukam and few other "unbalacing" balancers.


Once again, sorry for that heavy loss. 12 batteries no be beans, even if you're Chevron manager ( lolzzz)

Hmm... your load is going to be over 200w going by the things you listed.
But the information is not yet complete. How many hours do want to run these appliances? This will help calculate the number of batteries you will need.

Thank you very much

Coughing out N1.4m for batteries is not funny at all.

I double checked the set voltages so over charging is not the issue.

The charge controller is premium brand Victron and the inverter is Felicity.

I have used HA02 battery balancers for years without issues.

The 3 units of 4 batteries are connected to a Busbar so the Lenght of the wire (35mm²) are of the same Lenght.

I have made up my mind to change the batteries.

Really sorry for your lost sir! It's quite unfortunate, but like the white guys say "shit happens sometimes"

Maybe it's time to go lithium iron phosphate known as Lifepo4.
I stand to correct you that Lifepo4 is one of the safest amongst the lithium battery family... You can do more research and find out for yourself.

The beauty of it is that you don't need to connect several batteries in S and P but have a single unit built to you voltage and capacity as well built according to you application.

There's always a first time and we already have guy's within this forum with good knowledge of it.

kiekie1:
Hello amazing people and great forumites , it's been real tasking making sure i satisfy most of my clients needs / orders who commit so much cash & get their products in return ! Apologies to few out of millions who view but do not type that i couldn't attend to due to very busy schedule . I don't think anybody in God's name will come out and say I absconded with his / her cash for countless years of transactions done with me.. Issues of warranty on brand new items purchased by company who offered us warranty are treated with hitches unless for few companies who don't offer warranty or basically on fairly used batteries which I rarely offer written warranty but sell in good faith as most already know !
We've many who committed cash and got fast supplies and few with saddist traits who did very little or no deal and felt that coming online daily for tales / Epistles of unrealistic transaction which if at all it was as they paint it to be , I do cash refunds to be factual ! I am physically present in Lagos State and likes of Abunafiu, Niyi etc has been to my personal aboad . I also have so many who has met with me in person Saipro, Barezzi, Dam5reey, Pranil, Prime,Hisenjos, Richmond, Ola, enough installers and renewable energy enthusiasts etc and Boss George , Rovar who've transacted with me and no issues till date !
We face some challenging issues sometimes in our line of business as I have most who know absolutely nothing about solar product vis-a-vis quality , they commit cash to you under "abeg help me get something good under trust" like someone who I have transacted millions with and he needed a Korea car battery. I gave him option of everstat battery but after viewing pic he sent and terminal polarity position, I opted in for a quality Korea product called Sebang . The client issue was that he doesn't know sebang and I would have told him battery name before sending far North which I said "sorry for that" & also mentioned he can send back and I refund cash back since the whole business was just for old time sake not necessarily for humungous gain ! The client operated on deaf ears and threatened he was a lawyer called to bar decades ago and would do xoxoxoxooxo if battery fails but I only kept my cool and he has been here calling a fellow man like him names like he was his creator or the mistake/error of communication can't ever be forgiven by him as a mortal being !
The way Prime mentioned to someone here if he needed flames office contact, he can assist .. I deliberately sent receipt snapshot picture of a panel I got from popular foresolar warehouse on Yuletide break which all travelled but I tried my possible best to see client was happy.The picture was to show not all foresolar panels have the tag "foresolar" on it's nameplate which I confirmed from their CEO "Mr Ifeanyi) , the client never believed even after knowing I don't ever rebrand since my years of existing on this wonderful forum ! The second issue was little change which was gotten from my routine logistics bid just to use for my stressful shuttles that holiday but client felt it's another issue forgetting it's where someone works - the person feeds from and even a cousin,friend,sibling can also do that when it comes to business which is no criminal offense .
It has been a lovely family in here .I advice let's learn to live & let live ! You ain't anybody creator in here and can't be a lopsided / partial admin in minor or bit juvenile cases as we havemost who don't type here but are observers seeking for real serious cases not tantrums as kids do ! I don't feel moved by been JUST and UPRIGHT .. If you've any serious personal grieve with a fellow being , i am physically available for dispute resolution to reduce much unnecessary noise here and those who which to transact will always do by God's grace ! Why must someone call a fellow man a conman for a used battery deal without warrant receipts! Fraud for no single transaction which anyone absconded with cash ? Someone mentioned "it is finished" like he has the last say on partial judgement here . Funny gist is that the remaining few who type or do unnecessary LIKES on negative post like a saddist does, I do not know them not owe them anything to be keen! See few snapshot attachments below.. I have most who have driven down personally to my Abule Egba , Lagos State location for various item(fullriver,Ritar batteries etc) pickup and I see no reason for side talks here like infants do forgetting that the rough sea only grooms or builds brave sailors!
If I officially owe you a denari/penny , bring in on and I will PAY you OFF as a Freeman which I am!

Less I forget >> Am always available for renewable energy transactions as usual !

I will not go back to the past but just For the records Frankie you never made an offer for me to return the car battery you sent to me that was leaking fluid and did not last up to 6 months before u had to change. Anyway, it is like you can never change and you keep it up your downfall will be sooner rather than later. Just keep in mind that You need customers more than they need you. One day monkey go go market he no go come back. A good name is more than gold. Do have a pleasant year ahead.

Thanks for the response, the appliance will run for 12 hours maximum

Using a 12v system and assuming a 200w load, you will need
1. At least 2 units of 200ah batteries (roughly 200k).
2. A 1kva inverter (price varies, contact the sellers on this thread for a quote.)
All things being equal and excluding solar, 250k should get you the setup you need. That is, assuming that all the appliances are turned on for 12hrs non-stop. But if they will not all be turned on at the same time and money is a constraint, you can manage with one 200ah battery further reducing the cost to say 150k or thereabout.

DUNKA:

I really don't know which one
But I have attached the picture
It's 5kva Hybrid with 60a pmw (which I'm not using duh)

ceaser:


So I had to immediately change charging setting on the MPPT SCC from the default AGM charging setting to the Lithium charging settings, and also edited the maximum charging voltage from 14.5v to 13.9v.
.

So did you set both your float and bulk to 13.9v since lithium does not really use the float or bulk options? I currently have my float and bulk at 28.6 and 28.8 respectively. Just trying to figure whether to just put both at the same voltage level

Oga go and sit down. You are part of the 10% of kiekie's customers who got away unscathed. You see prominent members of this forum telling tales of woe regarding this man and you are here talking about your 1 review.

Go and read this thread from the beginning and see how many issues he has had with people and then judge for yourself. That you got your batteries doesn't mean all the noise is false. He is not the only seller here so there must be a reason it is always about him.

Enough said.

Again sir, shove your review up your ass. It is not needed here!!

NiyiOmoIyunade:
I need to clarify that it is not really about tightness of the connection but two factors come before;

1) Sufficient contact area between the cables being joined - i have found your typical near 1 inch of contact insufficient - perhaps 2 inches of contact is ideal and splitting the cables into smaller branches that can be wound/braided together better

2) Ability to weatherproof the connection and keep moisture out as well as withstand heat.

Think of it that the cables with cheap asian panels may be substandard but the use of MC4 is not magically upgrading the cables to a better spec, rather the MC4 ensures minimum viable contact surface area between the panels and keeps moisture out and is able to withstand the heat of the sun.

To reiterate MC4 metal contacts are pretty thin and unable to withstand the arc that comes from making or breaking contact under load, yet if used properly, they manage to create secure connections that last many years.

I encourage anyone to look into the anderson power plugs for DC connections - rated for about 100,000 no load connects/disconnects and over 200 connect/disconnects at full load. Even if you don't use them to connect panels together, a serious DIYer or pro installer will doubtless find many applications for them.

hi mr niyi. You are abosolutely right. I had to learn this when my 600w pv array began behaving like a 450W in practice. Lets forget what the book says cos there are so much sub-standard materials in the market. Mc4 ko mc4 ni. Except you have the premium ones.

Thanks you very much, how many solar panels will i need, should i go for 300 watt solar panels for instance.

Abeg, In conclusion we should use MC4 connectors or Just cut and join wires?

I'm thinking of MC4 connectors oo,

I remember when my panels were producing less power, I had to rejoin the wires after the wires on Yachi panel became Rusty and burnt, but the Yingli panel with aluminum coated remain intact no sign of rust at all..

MC4 is a good option, provided it's a good quality one.

Personally, I do use a kind of terminal connector shown in the picture, as long as it's protected from any weather condition (rain or sunlight). I can easily screw and unscrew cables in it...

And I normally, after testing and commissioning, still properly cover/seal up the open ends of the connectors

Cheers

If you will be using only one battery, make it 500w-600w for faster charging. 300w will do but it may not charge the battery fully before sundown.

I strongly agree - however try very hard to get a decent quality MC4 fom a reliable source and ensure it mates tightly/firmly with your solar panel's existing connector.

An el-cheapo will only cause stress and pain in the long run.

Trying to see if I could get Lithium from China, but the weight and the cost of shipping is proving tricky. Can anyone give me a reasonable price on Lithium 200AH 48V?

let us talk

There is believe in this forum that DOD does not affect lithium, this is not through. There is no battery that DOD does not have effect on. If you check lithium battery datasheet you will observe the graph decline from 100% DOD to a lesser number of cycles. Even higher charge/discharge have effect on the bms. Some will state 100A charge/discharge and at the same time put a recommended charge/discharge. Please note I am not saying lithium is bad in fact I will have 100ah/51.2v/5kwh and 12v/100ah/1330wh soon so if interested contact me

I forgot to add that I was scammed by the Chinese on my first lithium battery research over 2 years ago

Lifepo4 48V 200AH~10kw
Weight=168kg

Air freight=1.150M (3weeks-5weeks)
Sea freight=1M (8weeks-12weeks)

You can PM me if OK with it...

JUO:
I forgot to add that I was scammed by the Chinese on my first lithium battery research over 2 years ago

Sometimes buying from these Chinese guys can be very tricky, the smallest difference in price can make a very big quality difference.

I noticed that sometimes they pack lithium ion cells and call it LFP as well I've once gotten an offer for this kind of battery pack at $120 for 12v 100ah while the packs that are build like the normal lead acid pack cost twice or more for same 12v 100ah.

Substandard cells and cheap BMS can lead to the swelling of the battery.

For all I know the Chinese will always give you what you pay for and for those who don't cut standard, it will always be difficult buying from them due to high cost and sometimes not willing to offer smaller units.

Still would like to know the current state of the battery now.

nonoski:

I really don't know which one

looks a like an Axpert clone branded under Felicity. Those inverters charging parameters do not give it a true and proper 3 stage charging of bulk, absorbtion and float. The behave more like bulk chargers. Before you go for the change of all your batteries you may look at the inverter you are currently using. Regards

1. Charge Controller is victron blue solar
Setting is 54.4v for float and 58.6v for absorb

Inverter setting is 54.8 for flair and 58.7v for absorb.

@bolded seems victron and by association dont include bulk voltage setting in their devices, only float and absorb..
How or what then does the battery use as bulk voltage when charging.
I have a fangpusun 50aD and the lack of bulk voltage setting is giving me concern, exchanged series of mails with seller, no resolution.
For batts like kung Long batts, whose recommended cycle voltage is 14.4v to 15v and absorb 13.5v to 13.8v,
How do you set the cc to charge at the bulk/cyclevoltage, since the cc/inverter doesnt recognize/assign charging voltage to bulk charging state

Talking about marketing fraud, i just fell victim to A&E dunamis 15kva servo stabilizer.
I have a 10kva of same make wch has served me ok for over 4yrs, but due to increasing load, i decided to upgrade to a 15kva. Ordered same via jumia.
Lo and behold its same size as my former 10kva, and even same weight when i put it on the scale!!...choooi a&edunamis, but why
