Obnoxious2001:
Your system has no fault why worry?

Too much information don dey cause harm .


On your controller, the only thing you can Change or modify for the equalisation is the time it should take

Why I am bothered is because on the indicator of each cell, most are still around the green line but one in particular is lower than the rest but not at the red line. I was thinking if it does equalization charging, then every cell will be balanced.

Ferdiwar:
How does your CC determine the temperature of the panels.

Dam5reey1:
You mean the Internal change control temperature.

jonescosmos:
My brother, that temperature shown on that screen is the room temperature where that System is installed and such high temperature is not healthy for your Inverter, Battery and CC. It's gone way above the threshold.

Except of course you can show us the Temperature Sensor attached to the PV and wired back to the Inverter to get this reading.

Holy Bleep, I was pretty certain that was just the inverter taking a temperature reading from the panel. Which thinking of it now, makes little sense since the only connection from the panel to the inverter is a simple DC cable which isn't able to carry temperature data.

You all are right, it seems to be the temperature of the charge controller side heatsink.

It's weird, though. The ambient temperature of the room definitely isn't anywhere near that high. My battery BMS reports a temperature of around 31°C, and the inverter temperature was at about 52°C.

Edit: Figured out what was likely the issue. Vents were blocked by dust and grime. I've now cleaned them up and will run a similar load test when sun's up to see how temperatures sit.

Thanks for the heads up, I love this thread.

Please kindly do well to equally share with us how easily rePairAble this is.
Me can't imagine spending over 100,000 naira (including wayBill / Transportation) and not have the rest of mind it's rePairAble.

Another is, if cost of rePairs, is not negligible enough, then it's another NO. Make cost of rePairing 3 times no go be money wey go buy a brand new one. That Penny-Wise Pounds-Foolish.

You probably forgot mentioning if those heavy loads you listed above would be powered consecutively or individually. Say dem rate am 3,000-Watts , no mean say e no fit cry if you give am 2,500-Watts.

Gone are those days I suggest sachet inverter to those on tight budget. Those days, their costs were negligible enough; and even at that, I don't recommend to those needing anything beyond 1000 watts.

100,000 naira fit be small money for some people, to others, na over big money Ooo.

Abeg no vex, I'm not hear to spoil anyOnes market.

You no reach to spoil my market, brother. My focus in business is Delivering Value from the perspective of the customer, even before profits, and that is why I am still here today, selling this product across Nairaland, Jumia, Jiji, Konga and Facebook with over 95% verifiable customer satisfaction.

You have made this same snide remark about the repair-ability of this inverter before and you received the below responses, but cat immediately got your tongue and you never responded or acknowledged being clarified. Go back and read those posts, they are my responses to you

You can follow our main thread to read verifiable testimonies from people who use the inverter. If it wasn't that effective, trust Nairalanders to invade the thread with negative reviews:

The only thing I see worth addressing in your post is your comment about the load it can carry:
In my original post, I implied that the cumulative load placed on the inverter should not be more than 1,100w. Also, in the video I posted, these loads were applied alternatively

Thanks for the feedback bros. We are all here for exploring knowledges.

Okay. Wavy/corrugated roof is still better.

Yeah, the links mean better air flow beneath the panels.

Cleaned the vents, temperatures are a lot more tolerable now.

HeavenlyBang:

Yes. For mine, I don't even know, I think it's facing north based on sunset and sunrise, vertically placed. I will change it later when I am ready. Heavy stuff. Highest in this harmattan is 350 watts (555 watts panel).

Great, now the CC is breathing well.

Getting about 410w from each 550w panel, so not too bad.

Can you share the temperature of your room via your phone app. That can actually give a clue as to such a high temperature.
Bro in 35 degree celcius, you’ll sweat in a not-well ventilated room not to talk of 49 degree. Battery health is paramount.

Greetings

Please I need the help of everyone
Just yesterday I bought 4 pieces of jinko 615kw from fouani

It was installed on 5kva felicity inverter, 2 pieces of 220ah battery and 60ah felicity charge controller

The image below is what my charge controller is showing this afternoon, is this normal or is the connection wrong?

Added to what everyone has said, your pic indicates the CC has considered your batteries as full, so that's why you are seeing only about 200w coming in from the panels which is basically what you are using in the house at the moment of the pic.
There's no problem with that.
Just try to follow the advice of getting a better battery like lithium so that you can comfortably charge with 1400wh seeing you are using a small 60a CC. You'll never get the full power of your panels too except you change to 100a cc. Even if you do, only lithium batteries can chest that high charge current and not tubular batteries

Dam5reey1:
Na so jare people are too emotional.

I only show cell behavior if you discharge them below 3V, regardless of the manufacturer same applies across, if he read between the line he will understand say na only Cell I bought, the pack was built by me.

What I was expecting is a someone to come out and show me their pack at 47V, and lets see the Cells behavior, this thread is DIY where we learn not a market place. Where we market or demarket anyone.

I once mentioned this when there was arguments about cells grades and all.

I hinted that most LFP seller will tell you charge to 3.45 and cut off at 3V so as to cover some flaws. Now that is evident.

Many went against the Pack that can reach 3.65V without OVP getting triggered and condemn seller for selling a 14.6V charger.

You are still trying so hard to bring down some good trusted hustlers for no reason.
All we do here is DIY. The battery pack you have, you didn't manufacture the battery. You got the cells, same way others in DIY got theirs, assemble and sell.

I don't know what point you trying to make by saying trusted people here tell people to not charge above 3.45v to hide flaws.... Are they the manufacturers of the cells? As one who assembles grade A LFPs, you'll simply follow the instructions of the manufacturers in charging their batteries. You won't invent your own charge/discharge protocols.

Don't talk down on good and trusted people's hustle.

BTW, I repeat what I said many months back, 98% of LFP manufacturers in the world recommend charging their batteries to 3.45v-3.55v. It doesn't mean they are hiding any flaws and doesn't mean they can't charge safely to 3.65v (just that they see it as not necessary since anything above 3.40v in LFP is just waste of charge due to LFP charge curve). Only one who doesn't understand LFP charge curve and longevity protection can say such thing. You are experienced in LFP and these shouldn't be coming out from you.

You assembled your batteries, BRAVO ! Let others do theirs too and stop making yourself look good and others bad when you and all of us here no be battery manufacturers.

The temperature is not the room temperature. It's the temperature of the component inside the inverter (MosFETs).

Good Morning Bosses,

Please I need your advice before I install my setup. So i bought this inverter with this data sheet and 9pcs of 485w Jinko panels. Kindly advice the best wiring connection for maximum yield.

I was thinking connecting all 9 in series, considering the inverters Imax of 22A.

Panel Datasheet below

Pmax - 485w
Maximum Power Current ‒ Imp [A] - 13.38a
Maximum Power Voltage ‒ Vmp [V] - 36.25v
Open-circuit Voltage ‒ Voc [V] - 43.76v
Short-circuit Current ‒ Isc [A] - 13.93

Please advice me.

BlueStripper:
Good Morning Bosses, . I was thinking connecting all 9 in series, considering the inverters Imax of 22A.

Please advice me.

u are good to go.
connect all in series bro. I hope u have enough battery bank /load to download these lovely juices from panels

OK.. This big ones are always better..but i would advice you if you can raise some money go for Growatt or sern. Even felicity self.. Just to have better rest of mind...

toscotech:
That is the inverter am talking about

3kv and below

Thanks ✌️

odimbannamdi:
When you say "low end own", what do you mean? Which Powmr inverter do you refer to as "low end"?

Valto:
u are good to go.
connect all in series bro. I hope u have enough battery bank /load to download these lovely juices from panels

Thank you Sir!

I have a Bluecarbon battery that i bought January last year. I have been buying in bits and cant wait to get on board.

My Dream come through

Baba na me one return am.. OK since you gat solution to the battery, kindly enlightening me. I hv lil to no knowledge abt packing lifepo4 or ion battery or any battery for that matter. Installation was done Nov 2024,all parameters set as it was sent from the seller.. Just like val do send me and his pack never for ones give me headaches which was even bought long before uncle sako product oo.

At 1st it do discharge up to 13% before it will alert for low battery before cutting off .later to 20% now 30% then it goes off.. If you are the customer, tell me if you Wont be worried? Maybe tomorrow now it will start going off at 40 them 50 and so on..

So if you rili do hv solution for me, kindly provide rather than saying someone discharge below so so so and so and what to return battery..

See as me they so, na solution i they always look for... Abeg if you hv one for me, do provide.. To send the product back will cost me gangan money and to send it back to me as well..

Abeg provide me solution to save me the stress of sending back.. Thanks chief ✌️


And anyone here who want to buy sako product both inverter and battery, I'am ready to sell at give away price

6.2KVA and 10kwh battery all 2mths use.. Everything gitting 2.55M can give away at 2M last..

Kindly quote this message or DM.. Thanks

Dam5reey1:
And someone wants to return battery he discharged below 2.9V

You are missing the Point, Once cell crosses below 3V dont expect them to have the same Voltages, or be balanced. That was what I showed in the picture. Can you proof me otherwise with a picture of cells in a 16s configuration that was discharged below 3V that have good and balanced cells.

The pack shows all cells below 3V with average these range, 2.9V 2.8, 2.7 and 2.6V.. is that an issue?

If he had cut off at wetin una dey recommend, like 3.1V he wont see any difference.
