HeavenlyBang:
Umm, don't these numbers mean this is a 2.5kwh battery?

This looks like a 100ah 24v battery?

Juror:
You've don well, the battery is/has been charging but obviously it won't reach 100%.

Next thing you have to do is this, just when you're about to go to bed, take same set of pictures you just took and send them here, when you wake up in the morning too, do the same.
Hopefully that should give us some more data to analyze.

AndroBlaze:
Good spot. Though I did not think their smaller batteries come in this build.

Please KudozInteriors confirm to us all what your installer said before buying the battery and the price you bought it for.

Please as much info as possible so we can be sure who the culprit is.

KudozInteriors:
Okay. Thank you so much.
I will do exactly so

Juror:
Please share a picture of the battery label.

CuteMaro:
Boss calm down, your battery is 2.5kwh..No need to buy anything else. Go check ur manual first.

KudozInteriors:
This is the label on the battery.
It’s says 5120wh

KudozInteriors:
Let me fetch the manual.

AndroBlaze:
Wow, speechless and this is the first thing your installer should have noticed if he isn't in on this.

Sorry, please confirm, are you a lady?

Please also confirm the price you paid.

CuteMaro:
Guys notice that the warranty seal also seems broken.

KudozInteriors:
I’m a guy sir.

I paid 1m50k sir

All this one is talk. The truth us that the company has defrauded him. How can a suppose 200ah battery be reading 100ah and the time use correlate with 100ah. Wow wow

HeavenlyBang:
Well, your battery is quite evidently a 100aH battery. So 2.5kwh, not 5kwh.

It appears someone may have pulled a fast one on you.

Mavor:
I'm thinking they cost that much because they are higher voltage rated and LiFePo4. I am strongly leaning higher voltage cos they require lower current to operate which means less heat and no fans needed so no battery noise. Your LVTOPSUN is 24V abi?

KudozInteriors:
After the first time that the battery was dying fast, I had to click on the buttons on the battery and saw 100ah. Didn’t know what it meant but I knew that the sticker said 200ah. I snapped it and sent to my installer and the vendor. They said it means nothing and that it’s just the charging current but I just knew that the thing was dying fast while carrying my appliances. It’s actually possible that they did not send this to the factory and they kept me in the dark for 2 weeks.

I’ve been good to this guy. Why would he do this to me?
I’ve called him though and he said he’s coming to my house tomorrow.

Dam5reey1:
Still not adding up discharge that batteries to 21V till it shut down then charge again.
That is not a Li-wall.. but Li-Sun.

I got it for someone and it's 25.6V 200AH Li-Sun

KudozInteriors:
Please I don’t understand this sir.

AndroBlaze:
I don't think you should allow that installer near the battery again till you can rule him out as being the mastermind of this fraud.

If I were you, since the warranty seal has already been broken, I would open it up to see what cells are inside.

Dam5reey has already done this before, so the shortest way is to contact him or any other person not connected to this scenario to open it up so you can see for yourself.

I'd say it's almost 90% certain that it is a 2.5kwh and not some glitch in the software. However only opening it up will determine for sure, and one thing we are 100% sure of is someone has already opened it after you bought it, which is why the seal is broken.

Once you are certain of the cells in it, you would then know whether to proceed with the local option of police or my preferable option would be you do a youtube video casting out Sako Nigeria as a den of robbers, which would force Sako China to think twice and probably compensate you.

Again that's if it's Sako's fault and not your installer (for now he is the only person who clearly doesn't have a convincing story in this whole scenario).

KudozInteriors:
Okay. Thank you so much🙏🏼

If that one will serve me, then I’ll just go fit it. I saw if for N26,500 on Konga.
Thanks once again.

KudozInteriors:
Please I don’t understand this sir.

KudozInteriors:
Thanks so much for this.
I’m already thinking of arresting the installer tomorrow like this. I’m just confused like this.

I feel terrible right now.

Juror:
Don't arrest anyone yet.

Try to take the battery to Sako yourself, point out the discrepancies to them and tell them to disassemble the battery in your presence.

Iinnov8:
Regarding the emboldened; did you want to refer to VoC limit of the controller, considering the battery voltage (12v)?

If yes, then I doubt that is the issue here because the VoC of each of his panels is less than 40v and he is on a 2s2p connection, keeping the VoC of the panels less than 80v, the recommended VoC for a 12v system

fuckboys:
no, I was still under the recommended voltage of the cc for 12v system.


Total voltage was around 64v

4pcs of cworth panels connected in 2p s 2p

Each pv has a max voltage of 31.6v

AndroBlaze:
What he is saying is that you should still do a capacity test, what we recommended earlier to you when you were advised to get the shunt.

Charge it fully up and drain it to determine the capacity ( the only other way, beside opening it to be sure it's really a 5kwh battery).

He's suggesting it might just be a software issue (wrong parameters were input).

To be certain you will need something independent to measure usage or do it yourself manually (which I would not recommend in this case).
