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.

It's not a straight yes or no.

In a short circuit situation, it depends on a lot of factors, including the power source,. Public utility will be catastrophic because the source can sustain the power surge associated with a short. But with solar panel in a single series connection, no catastrophy as only the rated current Isc will flow. If the panel is well made and the cabling is rightly sized, the energy can be dissipated indefinitely without any damage.

In an accidental shocking (body touch) situation, higher voltage is more catastrophic..

For battery, unlike a solar panel, a short circuit is catastrophic because the battery can supply the the entire short circuit current without limit (very low internal resistance). In HV battery, if the terminals is not grounded (physically or capacitively), no shock ensued without touching both terminals.

Parser:
that hybrid high pv sef dey fear me! Like whooping 500V to 400V for person house.

Which is even more severe in electrocution between a 220ac and 400v DC.

And another thing have been thinking about, betwn a 200v/20A and a 400v/10A source which would cause more damage

I still feel for homes make PV array dey around 100 to 150 range for safety. Just my thought sha!

What did Emerse Fae achieve before he won the Afcon?

What did Pep achieve before he took over Barca?

What did Xabi Alonso achieve before he took over Bayer Leverkusen?

That's why I've been asking NFF to appoint me.

Kog45:
I just don’t know how person go Dey give dis kind effort negativity……even Taiwo Awoniyi was like what a great and scaring leaping but me I no Dey understand again o….make we Dey talk as e be nau even if una no rate the player.

If it's CR7 that scored this against Heartland of Owerri, you won't see any analysis from same boastful self acclaimed international agent.

@Emmypam Your panel Vmp may be too close to the battery voltage.
When insolation is high, measure voltage at the input terminal of the controller and also the voltage of the battery.

BlueStripper:


Thank you so much Edrizz

Max Solar Voltage (VOC) 400VDC

If max input current is 15A, doing 4s2p will waste a lot of valuable power as inverter will only take 15A from the combined 2 strings.

You'll be better off with 7s1p. The controller will clip the excess pv power to 3kw as per your nameplate specification. 7s will ensure your input is below 15A and VoC below 400V.

Setaleonoz:
Kane

Compare to Alvarez. Very unfair.

Meanwhile, CIV beat us blue black. That was a very poor and timid display from our boys.

mank1234:
If a team could reach final after loosing it's first team to plane crash, then nothing stops Nigeria from achieving same or even surpassing it, with just few injuries.

Can Peseiro be another Waldrum? He can. 'Never underestimate a man who is down'.
Peseiro is injured.

And our injured Peseiro did it.

Like Peseiro like Waldrum.

Next is world cup qualification.

I love the fact that we won RSA going to work cup qualifier later in the year.

Finally, it would be unfair to football, if CIV end up champions.

humility33:


So u will sub in Onauchu instead of Moffi for Oshimen whenever Oshimen is tired?
Who told we still can't initiate a counter in the 90+10 mins and Moffi with his pace and strength will be of help to utilise

Lolz. Some teams are home now because they wanted to initiate counter towards the end of a match.
A fish at hand is better than a thousand in the ocean. Or is there a difference between 1:0 and 10:0 scoreline?

Blueelf:


Oga, at this point, let them have him. He is making Super Eagles games to be too close for comfort abeg

If una like, make una insult me. Na una way be that

Someone dropped a post here how the SE have created the lost big chances of any team despite not even playing an attacking style of football and psimhen as SE top 9 can only convert 1 yet Nigerians should just keep quiet and.manage it like that. Omo make una rest!!

Even Drogba would not play this bad for a long stretch of games. You think if he continues like this, even Chelsea would want him? Dey play

I won't take you serious because you're a fair weather fan. At a point I thought you're Ghanaian.

How many goals did Giroud score when France won world cup? Was he not their number 9?
Even the last goal Lookmn score HD his signature. All the defenders were rushing to goal line with him while Lookmn attacked the space.

TheSuperNerd:
Simon Adingra.... Super sub. What a substitution.

Mali showing how indisciplined they can get at the back.

Allowing 10-man CIV to equalise is just unfortunate from Mali. 4 fresh players in for Mali and they still crack.

Though not the root cause for the goal but changing 4 players at once is not a good strategy. At most two. The payers need few minutes to blend into the game.

Lazy defending by CIV. That guy showed intent to shoot since and they couldn't close him down.

Can CIV defend for 45min?

Offside is correct call

M7even:


Lol for matching their AfCON trophy and not surpassing it. An AFCON trophy that they have last won in 1982. And we are just about equalling. Give the little country the flowers it deserve, I mean how could the likes of segun Odegbami, Christian Chukuwu, Steven Keshi, and JJ Okocha play so many years and still deliver only 3 AFCON for us. I feel we should easily be on 9 AFCON trophies by now.

It's because our target is always semi final and not the final. Too bad for a great team.

ThunderFireAgba:
Do you think we can displace Morocco at the 12th position if we win AFCON?

We will still be 3. You need longer run of games to get enough points to love you that much.

If it's uzoho we would have been 1 goal down and that our goal wouldn't hve come because after scoring Angola would be all back defending.

komekn:


The trouble with stats they don't tell you the quality of the assist and or the goal 🥅

A player may have dribbled and skilled 6 players before passing the ball for someone to tap it in.

Michael Olise was taking players I and giving pin point accurate crosses both of them are poetry in motion. Eze goal from a precision ball from Olise simply Magical.

I agree with the bolded and would have liked this post. What followed after is typical of you and may not be accurate. Someone scored hattrick you didn't mention him. Were all his 3 goals tap in?

This CIV is going all the way to the final.

Thank you CIV.

Which team is stopping this Senegalese?

dollarnaira:

With lithium or lead acid?

Lithium.
The person mentioned connecting 2 12v lithium battery in series. Each of these 12V battery would have their own bms controlling only the cells within itself and would be unaware of what is happening in the other 12v battery.

mank1234:
North Africans and tricks. How's that a penalty?

May be it's to correct the error in allowing DRC's goal

brightk:


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

Series or parallel? Can you draw your connection?

If connected in a series, anyone to first gets to 100% cuts off charging an anyone that first gets to low voltage cuts off discharging. As the internal resistance between them is not same, with repeated cycle, the difference in capacity between the two will become much.

North Africans and tricks. How's that a penalty?

dollarnaira:

Batteries of same chemistry can be in series.

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.

lexyman:
EG was so unlucky ! although they had a good tournament .

Unlucky with 0 shot on target.

Equatorial Guinea left after toping the group. Same way we left last term.

Komekn Cameroon must be daft for benching an EPL keeper playing in one of the best team in the best league in Europe.
How can you bench your best player?

daveP:
Mauritania will qualify ahead of CIV. O boy. Another powerhouse bites the dust. The energy in their veins...truly they need be checked for some form of enhancers. Lol.

CIV will likely still qualify.
