50A

50A x 53V is just 2600W.
In the day, when sun is up, I'm sure your total load is more than that. During mppt tracking (for deye) solar output drops to 0W briefly and the load would be on battery.

Changing that to 115A, should solve your issue. Connect all your panel back and observe for some days.

Ferdiwar:
Thank you for your response.

The max charge/discharge current has always been on 0.5C since installation and the only thing that needs surge startup is the fridge as all my ACs are inverter AC. I'll adjust the the max discharge current to 115A and see how it goes.

What was the maximum discharge current value in the inverter before?

[quote author=Joezinho post=130526049][/quote]That's the logical thing to do, world cup or no world cup. But trust the NFF to go for a foreign coach who will fail.

Ferdiwar:
Kindly explain more of the No 3 please.

As for No 2, the total installed panels are not up to 6,000w.

The installer will be coming over the weekend to carryout a check to determine if there's a short circuit to frame or anything like that.

For number 3, go to settings, then battery, scroll to the second page, it has figures for maximum charge current and maximum discharge current.

Maximum charge current - set to anything you want. This is not important since your panel is not more than 6500w.
Maximum discharge current, leave it at 115A to accommodate startup surge of some appliances. If you set a lower limit, DC overcurrent will be reported when you try to draw more than that value from battery. But be sure that your total connected load is not more than 5kw.

If the above was already correct, (ie discharge current 115A limit) then the issue is number 1 as earlier stated.

Ferdiwar:
No but I just discovered that it threw this error code instead F14 DC_OverCurr_Fault.

It's the same error. The number may be different in different model. And the cause is what I told you before. 1) Your panel is exceeding 17A Isc during favourable condition and your controller is thus unable to clip the Imp to 13A.
Or
2) Total wattage at that point is in excess of 6500W and the unit is unable to handle the excess.
Or
3) Your discharge/charge current limit is too low relative to load and panel size.

U c 5million for dis economy,u no happy 😃😀😀😀

Abeg make I go dust my cv sharply 😎

No be by CV dem take appoint Finidi na . Someone wey dem talk say CAF no allow make e sit for bench for Enyinma match.

Shame on osimhen if this is true. Really disappointed in him.

When student don't like a teacher, they skip class. If it's true, the blame is to NFF, they should consult top players when they want to hire. Two cannot work except they agree.

What happen if you use Toyota ATF WS.where Toyota CVT Fluid FE is supposed to be used? What is the difference between the two.

Torino joins Inter Milan in race for Super Eagles goalkeeper Maduka Okoye

According to mondoudinese, Torino are interested in signing Super Eagles goalkeeper Maduka Okoye who has been linked previously with Serie A champions Inter Milan.

The Turin-based side are preparing for the possible departure of Vanja Milinković-Savić who was once on the books of Manchester United and have identified Okoye as a possible replacement.

The 24-year-old returned to his brilliant best last season with Udinese, helping the the Bianconeri maintain their Serie A status with a series of brilliant performances in goal.

His reflex reminds me of Enyeama.

Oshomo12:
Kindly clarify this statement, is it inside the inverter, done by deye herself or installer done?
Why not connect the jinko panals only and observe the inverter, since you have connected the other string without issue.

I told him the Jinko is the issue. That it's Isc might be exceeding the 17A during sweep on favourable conditions. He said it hasn't exceeded 12.5A before (refering to Imp).

TheGoodJoe:
Lie small now!

Guardiola's style has not become popular in the time of Amodu. 😂 😂

Tell the truth. Was he not sacked because we were not playing beautiful football. Tiki taka is synonymous with good football. I won't be supprised if you were amongst those criticising him then. He was pragmatic. He was reliable on rescue mission.

Napoleon55:
1994 set are not the problem,
some of them might not be good enough,
but how about some of them that are good?

Siasia played good football with U20 WC and Olympic silver to show for it,
Keshi won us AFCON,
Amuneke won us U17 World cup.

Oliseh and Finidi can b said to b woeful,
Eguaveon failed but not woeful.

Six of them have been tried on d national team job,
three of them was successful, three of them failed.

So how do u justify getting rid of them entirely when some has proven to b successful?

Mine is not if they are good or not. Mine is on how they were criticising and belittling Rhor's success. When it's their own they won't see anything wrong.

TheSuperNerd:
More fair? Fairness isn't by local or foreign. It is down to the actual selection decision-making competence of the individual involved.

Was it not Lars Lagerback who also picked nonsense? Rohr, in his final 2 years with us was rubbish too in his selections and decision makings.

We have had them both local and foreign mess us up in terms of selection.


Not ripe for a local coach? Was Festus Onigbingbe from Togo when he led Nigeria to Afcon Silver in 1984?? Amodu Shuaibu remains the only coach who has qualified Nigeria successfully for 2 World Cups AND HE IS BLOODY LOCAL.

It is the choice of local coaches that matter. So snap out of your delusional fallacy.

I miss Amodu. On both occasions he did it on rescue mission - when other mess up. Unfortunately, each time he qualifies after Afcon third place finish, the tiki taka crew will mount pressure on a willing NFA to recruit a foreign coach (for perceived cutback).

lbrichman2:
We were never going to beat South Africa and Benin, let's tell ourselves the truth..
Finidi's issues nothwithstanding, SA and Benin had been in camp for weeks training and perfecting team strategy and cohesion

Our own players strolled into camp late, thinking they would have it easy.

Finidi is the scapegoat and he may probably be sacked
But truth be told, we were never going to beat both teams with such lackluster behavior from our players
And it showed on the field
No fight, no urgency
See how Benin players wan die for pitch!
That's what I'm talking about

True. That's because they don't regard the coach. We saw all this when we were saying let's stick with Peseiro. We're they behaving like that before now?

Goke7:
we said then that we needed a Lesson learned strategy from Afcon but all the attacking football analysts said it's anti naija football.

sticking with Finidi is a higher risk, am sorry he doesn't have the charisma to charge the boys forward. We have lost something huge after Afcon, the pattern Finidi is trying to play, we don't have the full personnel to execute as Finidi is trying to add something he thinks is missing from the Afcon experience. What he's trying is what Paseiro also tried before Afcon that did not work, make we no deceive ourselves

Yes you're right. After the first game at afcon that we drew he saw that we were poor in defending and that we struggle when we conceed first. He changed strategy. This his disciple that was with him and should have learnt something, jetissn the idea and gave us the worst of defences.

A team is as good as its leader. A zebra can not lead a pride of lion.

lbrichman2:
Very tight..
Even if we win all our games, we still need other results to go our way ...

But we should do our part and win our remaining matches
Warrior mentality is needed
Zero room for errors or mistakes

We must become that resolved and put together a Man City-esque end of season winning run..
Then hope other teams drop points
Anything other than that, were out

We put ourselves in this situation unfortunately

Nigeria will not qualify. Stop this false hope. Will all the teams go to sleep like Nigeria? On a good pitch you can't play, is it on artificial turf you will play well?

dijon:
Patriotism isn’t always about local solutions.

Patriotism is about wanting the best for the country even if the solution is foreign while also closing the recognized gaps and improving on the local solution to be at par with foreign solutions.

Our local media and NPFL apologist damaged SE.

Top on th list is Segun Odegbami and 94 set of SE.

Marjoribanks:
We have been so unlucky! Awoniyi missed an open net against Lesotho. Likewise, Moffi missed a 92nd minutes 1v1 against SA. Today we conceded from a long ball and corner kick. lol! God of football is not on our side.

Ekong, Simon, Osimhen, Aina, and Onyeka. Half of a team starting 10 at AFCON are missing.

Look at the bench who were available? Fisayo injured, an unfit Boniface, and Onyeka.

We need to support Finidi! What would a foreign coach do better?
We need all our players back and fit!

We will win our remaining matches and qualify for the World Cup. Keep the faith.

Are you saying the opponents had better player than Nigeria? How many times did our two point men struggle for the same ball instead of one running behind in anticipation of a drop ball? That is a pointer that there was no pattern. They just assembled the team and let them play as they like.

9JAMac10:
Is it still possible for Nigeria to qualify for the World Cup?

On paper yes. In reality no. I don' t see any team with less than 4 points after 4 matches qualifying.

mostob:
With due respect sir, you sef are not serious. Imagine the kind o excuse you're making for Peseiro.

Lolz. I couldn't help but shed tears when I saw Obuachu and Boniface going for the same ball not once, not twice. It was like school children playing. That's down to the coach not understanding how to use his payers. Peseiro did same thing but later learnt. Thought Finidi having been with him all this while would have learnt also.

I would have said let's wait for siasia but as e don spoil so, del go say n him spoil of we still fail to qualify.
Those saying Peseiro started the failure are not serious. At least he drew the away game on an artificial turf. This one failed to draw on a good neutral ground football field.
Finidi should finish up the mess.

After the fourth round we are going to be at rock bottom of the log.

Ferdiwar:
Since I installed both panels the inverter have never pulled more than 12A from the panels. The highest I've seen from the CC (MPPT 2) with the Jinkos is 12.5A and about 10A+ from MPPT 2 with the Longi panels, so it's not the current but voltage.

I'll open the inverter and check the connection inside.

Take note that reversing polarity may cause failure of unit.

THE RETURN OF THE ERA OF CALCULATOR IN SE QUALIFICATION MATCHES.

Observation: Bafana Bafana has always been a tough juggernaut for the SE of recent. It has always been either they beat us at home or we barely escape with very slim margin/victory in competitions played out of Nigeria (Afcon).
Coupled with this abysmal preparation( inexperienced gaffer, withdrawals and debutant call ups) and playing a prepared, tested and refined SA team,its going to be a very long night for SE in UYO.


My verdict: This two matches came too early for the gaffer and there is nothing he will add to the playing style of the SE but only a disjointed, chaotic display and SE will only take one point from six maximum point in the June matches and this will be the albatross not qualifying for the World Cup.

Prophet Dijon

Napoleon55:
The way I see things now,
Without Osimhen playing the rest of the matches, we may not qualify or even win any away games.

We always struggle whenever our major star player is missing.

No way we would hve won this game even if VO played.
The coach is a goober.
The players are not serious either.
They are playing passing football without movement.

Ferdiwar:
Update on my setup.

Sometime last month I connected all my AC to the smart load of my inverter, and noticed that the inverter was going off and on repeatedly for like 5x before stabilizing back on. This would happen severely in a day before the sun goes down as I discovered it only happens during the day.

As a result I reverted back to the previous connection and disabled the smart load thinking that was my issue, but it still persisted, so I did some reading online and concluded it might be a software bug.

I emailed Deye and requested for diagnosis and update which they did by pushing a remote firmware update to the inverter, yet the issue continued (in my mind I was like I spent huge money to buy a faulty batch of an expensive inverter). I sent an update email yesterday to Deye explaining that the issue is not yet resolved (yet to get an update though) after it happened for the 2nd time in the morning (around 11am). At this point I thought it wise to calm down and observe the inverter when next it happens rather than be angry, so I stayed put in front of the inverter and watched it.

Few minutes later it happened again this time around I was watching the screen and boom I caught it in the act and it happens to be that the voltages of 2 strings of panels attached to the 2 MPPTs of the inverter exceeded the max 500v of the inverter (string 1 5x Longi 570w panels was pumping 240v+ as at that time while string 2 5x Jinko 625w panels were pushing over 265v both exceeding the 500v max voltage).

As I saw that I quickly switched off string 1 breaker and the inverter stabilized instantly which suggests that the input of the 2 MPPTs are somehow connected in series or something like that as one of the MPPTs can take 500v alone but the 2 MPPTs combined together is still 500v.

No matter what you do, do not exceed the max voltage of your inverter and take not of the tolerance of the VOC of your panels when connecting your panels to your CC or inverter to avoid stories just in case your inverter or CC is not equipped to handle any form voltage spike above the rated max voltage of the inverter or CC.


@Jonescosmos the 500v is for the 2 MPPTs after all

This is invalid diagnosis.

All 5kw upwards have at least 2 independent trackers.

Both mppt are independent of each other. Check your error log. My suspicion is;
One of your string especially, the 625w may be exceeding 17A Isc during tracking. Very likely when sun comes up after cloud on a rainy day. I use same panel but luckily for me my roof is steep. My inverter clips the input current to 13A Imp. If it wasn't steep I'm sure I would be running into same issues.


The model you have has 13A as Mac input with caveat not to exceed 17A Isc. Your panel is exceeding that limit that's why it happens. I'll suggest you change panel to panels with lesser Isc else the inverter would spoil in the long run. Ideal for that model is Longi 450W with Isc less than 14A

BascoVanVeli:
Onuachu had a good game for someone without service. If he had missed opportunities like the one Moffi did I would understand the complaints

Onuachu that went to EPL and flopped. As tall and huge as he is, SA were getting the better of him repeatedly. I repeat, if Onuachu was there he won't position himself to receive the ball Moffi received.

Iheanachio that Leicester most times don't even name in their starting lineup becoming a starter yesterday was like a dream to me.

twentyk:
Cant believe this😱😱

I just saw that Moffi miss from a highlight.

How could he miss such chance for God sake.
What else does he want?? On his left foot again. Abeg that guy no be striker. Even Onuachu go score that goal.

Onuachu
Dessers
Sodiq
Moffi.

These four no follow.

Onuachu won't get that chance because he won't be where Mophy was.

Okay, any drop in the lithium performance?.. i was thinking of upgrading to lithium soon. All the hype about lithium. Even mobile phones that use lithium battery, over the years the battery does depreciate. Phone wey dey last one full day after purchase, 6months later, e no go reach again..

My 5 year old phone must have done over 3k cycles by now and I guess the capacity would have reduced to close to 80%.

If your phone is not doing that, it means the charging system is not suitable. Charger supplies 5v, your phone is responble for sensing when battery is full and cutting off power supply to the battery. It's also responsible for knowing what voltage it should consider as empty and shutting down.

It's same for inverter/bms. There's no hype. There's a reason no EV is using lead acid battery.

We won't develop our u17 and u21 but when we see u17 and u21 that other countries developed, we start dreaming of luring them over.

TheGoodJoe:
We have to consider time. At the time Messi and Ronaldinho were becoming greatest of all time, football defending and tactical play was behind. Today, many teams will not allow too much hugging of the ball. Especially that of Ronaldinho.

Tactics is the new skill.

I doubt. Today vinicious, mpappe etc still do it. Messi, Ronaldinho would still do it today if they were around.

Dribbling is a skill in football. It's reason Zidane, Ronaldinho are rated over Debrune despite the stats.

It is smart world, anything you can measure can be used as a condition to start or stop something. Let me just share a snippet of my water heater control.

Bonus: You can see that when my water heater is about to come on, my AC (ACSolar) is first switched off.

Nodered?

jonescosmos:
Hmmmmm? Like seriously?
Well what you just talked about has to do with your Raspberry PI Distribution Board or Smart DB or even some bunch of programmable timers in conjunction with your Inverter Dry Contacts, Perhaps you could tell us with visualizations how your Battery SOC between (30%-80%) would be a determinant for the behavior of your smart setup.

What he talked about is not what Gencos should dabble into. Load shedding is not their concern.
