Problem solved.

This is Catl 302ah that I want to couple for someone. As usual, I hooked it up with bms to move the charging limit to about 56v before carrying out the final top balancing.
Tonight, I decided to put heavy loads on it and observe the cellvolt diff. I was shocked to notice that almost all the Eve cells I've carefully top balanced has never performed as good as this. The cellvolt diff has always been higher than this with the similar loads.
Eyes are too much on Eve. I will pay more attention to Catl henceforth.

is 56v not on a high side. Dat shud b 3.5v per cell. Am open to corrections bro

bassdow:
Nigerians and PRAYERs. hmm

Are u daft? Even if u are daft dont u kno wen 2 kip shut..

Has anyone used cee power inverters here?

Hybrid600:
Anyone heard from Valto? Hope he's recovering well. Speedy recovery to him and all that are under the weather.

I paid him a visit yesterday. Lets put him in our daily prayers. He will b fine by Gods grace

My Jinko panel is clean. It is brand new. So no dust on it yet. Just 3days old and I have been taking the reading over the course of three days. Good shinning sunlight. Yet the max I am getting is 270w out of the Jinko 550W

what is the orientation of ur panels? Cable distance and type of cc

JoeSef0:
This part has been eliminated already

This issue only happen on the inverter
Gen and phcn works fine, even while the inverter is connected and charging with PV. If nepa light come or generator is on
Everything is okay until u switch to inverter.
i.e. The problem is only present when pv is changing and inveter is working. Doesn't happen on nepa or gen

get anoda cc and test pls.

JoeSef0:
They said it's Mppt on paper

I spoke to their office i bought the inverter from. After so much do this do that, they finally asked me to bring the inverter in for them to check up. Maybe na replacement e need or what not. Inverter wey i just installed for Akure o. Client is really pissed now, he said i should just come install a secondary charge controller and we should just move past the issue because inverter fit reach their office mak dem say nothing do am and they send it back again.
My issue is if I'm to install another CC, na pwm e go be cos I'm not about to spend over 100k on a CC wey client no go pay for and if the one built in with the inverter is really Mppt then it will work better than the PWM.
I just dey confused like this

this ur issue only happens when the pv breaker is on. Please disconnect all devices both inverter, wires, pv, battery and all breakers like u never installed anything Start troubleshooting with a gen set then move to phcn. If none of these isssyes occur on both sides then reinstall your devices one ny one. First only inverter and battery since its hybrid) then try to charge from phcn or gen.observe if the issue occurs there.

If u feel this is going to b a stress. Just get a temporary cc to test before you tink of buying anoda

TechGeek777:
Does this price include lightening protection to the ground?

recently did earthing with thunder arrestor tru a friend for 200k.. i know if its from a professional personnel i might cough out 300k.

HAS anyone patronised techland. I got the contact here on this thread a long time ago but because no recommendations i didnt use them

JoeSef0:
Sms sunmate 2kva

hmmm. Was it liie this the first day u installed?. There might be issues on your inverter

JoeSef0:
What could be the issue here
I noticed whenever I'm on inverter and I'm using my phone while plugged in, the phone touch start malfunctioning, even my laptop trackpad and touch also malfunction when plugged in on inverter.. this doesn't happen on gen or NEPA.
Abeg who don experience this thing b4

what kind of inverter are u using?

isangjohnson:
I disagree with your submission in terms of lfp battery quality in USA.
Most of us here are members of other forums dominated by foreigners including USA residents.
Maybe I would drop some lfp battery USA warehouses including reviews from various companies (Docan, Luyuan etc) and perhaps the issue some people are facing there regarding the genuineness of the products in question.
Someone shipped 280ah cells last year October from New Jersey with no signs of use and the manufacturer date of March 2023. He was happy that he has gotten quality cells but when he dropped the pictures of the cells in the forum for confirmation, Steve_S and others told him after the analysis that if he removes the black cover from the top of the cells, they're certain it would show signs of sanding and re-lasering. Of course the cells were not legit.
Most of us are facing the same issue from these dubious vendors. The latest Eve grade A 280ah version comes with double screw terminals and test out at 292-298ah and will deliver the full 280ah working voltage as intended.
We should take note of the terminals being used on the cells. As usual, grade B cells will have welded studs instead of dual hole mountings.
Unfortunately, some vendors are still flogging cells with tapped holes.
Submission: A lot of people from USA are buying fake cells just as Nigerians do.....
If you don't know, you don't know.

sites like batteryhookup.com and 18650batterystore seems to have the double holes on thier eve 280ah cell. D price now nor b here judging our current dollar rating

Obnoxious2001:
Omo Na really finishing

At least one point Is clear, there is no hybrid inverter with lithium profile coming from India.

Am speaking in respect to Nigerian market.

My point is this countries are operating on certain government regulations(am very sure why India is not producing lithium stuffs, it's due to environmental hazard).

You see that flooded batteries, luminous are not the only ones guilty many big name are on that table.

For the LVD Na true , then no go sell market if they do it at 11v😆, besides users will complain that the battery goes off too early.

I have met a clients that asked me to adjust the low battery. (Some inverters has option for you to choose the LVD)

what is the actual capacity @ 11v

dollarnaira:
See finishing...
Mortal combat style

@Obnoxious2001 com n defenf ur india brodas ooo

Obnoxious2001:
What criteria do we use to define a good inverter and cc?


Both yohako and felicity are both Chinese.
Felicity is beating yohako in terms of packaging and organisations.

Na the same people.
I don't see any difference between this two products.

u have com again

olaztek:
Building a reliable and safe Lithium ion battery pack is very hard and time taking.

How can one make it a business when you can't finish 5 or 6 orders in a week?

invest im quality tools. I tink dat wud help alot

mank1234:
Yes you can buy its recipe for quick failure (lithium)
It's not recommended. It's better to go for a 24v battery at once.
In the long run, imbalance would set in.

I never understand this lithium chsrging failure wen in series. Abeg make una let me understand. Cos i have one in series but connected to a busbar and i dont see anything wrong. Me i nor de monitor anytin. Install n move to d next available job

kristien4:
Get thermocool instead...hisense inverter Ac is not inverter enough...

hmmm. na wa

Obnoxious2001:
I got in with my journeyman and we started preparing the mounting rack ( we used interlock aluminium profile for this job, from experience I think they have better stability when trying to nail them into the roof)

We did some calculations to manage material my oga you dey owe me . So we ended up using 3pcs of aluminium profile to mount 8pcs of the 550w solar panel.

Preparing the railing was not the problem self, pulling the panels up the roof was too stress full (all my body done break forget I said I was made for this 😭😭).

There where some many challenges with the ridge board has broken and some of the wood.

So we had to swap position (who dem dey lead sometimes no know Wetin leader they see) with me myself taking the most risky position on the roof.
We dont have pictures of the process just minor clips here and there.

But am grateful, am able to come back to this thread to document it
.
Shout out to all the key people involved in the project.

Hopefully, we I will be sharing update on battery and inverter system.
We are having some down time procuring the batteries

Lol... money don finish

Valentinooo:
This is roughly 60% at noon. That's not too great.

I have read it here several times that the original jinko panels sometimes generate more than the stated capacity.

maybe u shud ask how the panels are connected, wat kind of controller he is using,panel orientation, cable length and size

Obnoxious2001:
I must confess men carry 550w of this solar panel is very heavy.
I will try to do justice to ascertain how much it weighs tomorrow, because we have to safely move this gadgets upto 2 storey building using a ladder 🪜🪜.
Am very sure you don't want to miss that
aspect of this story.

I will use this night to fast,hopefully it shall not be our last. But in all, we shall prevail. .

After the bustle and planning, my chairman at @brightk said let go and eat with igbe (sacrifice in Urhobo) plate in one corner.
Shout out to the people whey dey call us come chop🙌🙌🙌

lol u nor well

tysontim:
How far any Good news op?

gud news 4rm where? E wants to eat his cake n have it. 1 naira wen wash e nor go see.. u tink say bet9ja nor get sense

kristien4:
thanks for the headsup. Lemme go do my 900pages..

lol

FEGEITOK:
The calculation that helped me decide which panel to buy:
To calculate the ratio of watts to dollars for each solar panel, we'll divide the wattage of the panel by its price.

555-watt solar panel:

555 watts / $166,000 ≈ 0.0033 watts per dollar

600-watt solar panel:

600 watts / $202,000 ≈ 0.0029 watts per dollar

670-watt solar panel:

670 watts / $224,000 ≈ 0.0030 watts per dollar

Comparing the ratios, the 555-watt solar panel offers the highest ratio of watts to dollars, indicating that it provides the most wattage for the money.

Substitute dollars for Naira

Add the cost of freight to the cost of the panel for a more accurate figure

My oga i salute ooo. This your analysis na die oo

hi everyone,, am having a hard time choosing between canadian 600w panel, jinko 550w and 580w panel.. am on a tight budget and want to replace some old sticker panels i have...

i would appreciate your comments..

thanks
