Hello Sir, I believe its my personal post which dosnt really affect you in any way as anybody can quote a post on the thread .. Its not illegal ! So you can simply ignore instead of scouting for irrelevant issues. . Thanks

You are forgiven, son !!!

This is bad for appliances, that it is 1kw doesn't mean u shud load it up to 1kw, u ll kill it gradually, for me i won't even do 800w,thats 80% broda... Get a higher inverter dat ll do 800w comfortably

he is suffering from thermal throttling . . .

Hello, Kelvin 20kva albs is an Indian brand which uses 30 batteries .. It is a pure sinewave inverter which operates from 0°-45° temp with features like;
-All necessary Protection like Short Circuit, Battery Low/High, Electronic change over, hence better reliability, High performance voltage and current regulation with DSP control, Mains MCB Tripped etc. with Comprehensive display., Over Temp etc

Emerson brand as stated above must be 110v ... Cheers!

110V for Naija ? huh

That, my friend, isn't a satisfactory answer to my question . . .

You have just answered the question,

Yes it's shows I bought real 300watts panels, then I can troubleshoot other things like cable, controller and so on... Cheers..

You see why I said you're confusing yourself . .

Take for example, the OP asked me this question and I answered in the affirmative, the OP goes home happy

and sees only about 55% panel power under intense sunshine and he starts troubleshooting like you . . buys a $1500 controller

and uses 00 AWG cables all through and in the end still gets no more than 77% ; and the sun is blazing hot outside?

What is your resolution; since he didn't buy fake panels, nor fake controllers; and used overkill wiring . . ?

with installation near perfect, all being equal ?

Good, could you please answer this again!

I received my panel today and took it out around 12 noon for bench test if I measure both Voc and Isc; Am I supposed to get values close to the panel spec VOC = 44.3, Isc = 8.93A?

Yes, you should get values close to that . . .

And why sir do you need those values ?

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by makavele: 3:59pm On Nov 27, 2017

P.S.: I am not also practical; I am highly controversial . . .

Y'all should start getting used to it . . .

You are still not getting it...
How do we then know he bought real 300watts panels and not a fake 300watts at the back?

I use a 1kw inverter,
but it cannot power power a load of 800W continuously then you tell me it's 1kw

You are practical person yet you use multimeter to measure your current instead of using the sun intensity to calculate...

You have not answered his question correctly... That was why I disagree...

Let me break it down for you sir . .

What do you mean sun intensity to calculate . . ? LOL

You be confirmed olodo

I need real life answers . . . So i go to my lounge; hook up a multimeter and see what is coming in . . . How simple can it get . .

I don't even take into account what the Charge Controller is telling me, i check voltage and current and resistance manually . . .

That's an overkill for practicality . . .

Back to you: Let's be honest and serious for once . . .

Even with a Yachi, Yingli, Solarworld, CanadianSolar or brazilian whatever . . in real life specs; you cannot get 91% of panel specs . .

That is the answer he needs. So if we go back to why I told you all to discard the manuals, now you see it.

Under STC, a 100W panel should produce at least 99.9W of power . . . but if you are basing your judgements on STC, you are headed for an

epic world of failure or regrets.

He asked a question, f*ck the STC; give him a real life answer . . .

if he gets above that, good . . ; if he doesnt, then he won't be disappointed.

Makavele, he asked a very simple question...

And I gave him a real life answer !!! I do not care about his Isc and Voc , Vmp or Imp or whatever. . . he doesn't care about it too . .

I only care about the end result of all multiplication = Wattage

What he wants to know . . is:

if i have 100W panels, can i get close to 100W on a very good day with sunshine aplenty?

Simple answer: NO ; realistically ... no need for too much Isc X Voc mathematics.

Please go back to his question initial question peace..

https://www.nairaland.com/390522/solar-energy-complement-fta/276#59001874

Young man, calm down and learn 4rm ya elders . . .
I have seen the attached and yes he did get about 99% . . and I bet you it wasn't sustained.
If it was, it would be replicated on another day sooner or later; and I couldn't find it.
It was instantaneous and that is not what the OP wants to know; unless the OP himself is confused.
Looking through his question; he wants to know how much his panels can deliver during good sunshine in order to charge his batteries well
If you are giving him false hope of getting sustained 91% and above; I so pity those batteries.
SO go back and read what i said about "instantaneous" and "sustained" generation.
Shalom.

Yes you should get, up to that about few months ago some guys posted their results for a Month...

I can't remember their monikers, Those with 4500Watts setup can post their last month Generation this will clear the air...

Generation is generation; irrespective of wattage or panel strength . . . I don't want to look at a full month's statistics to get an answer;
because it will only show me "peak" generation for a day . . (which could have been say 95% for just 10seconds) .. which is trash

or "average peak" generation for a week/or month or year . . also trash .

I am talking about sustained (prolonged) generation during peak sunshine . . which is what I think the OP means?

Unless of course, I misconstrued him . .

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by makavele: 3:30pm On Nov 27, 2017

Dam5reey:
The readings were measured with multimeters, Also I mentioned Peak, that was the question he asked...

If the panels you bought cannot provide close to it's rated capacity at a bench test, go and change it....

WHy you dey confuse yaself, Mr Man?
You mentioned peak yeah?

Did you generate 91% consistently and continuously for say, 10-15 minutes during "peak" sunshine?
(i find this hard to believe)

Or did you generate 91% for just 1-3 seconds . . which I would term as "peak" generation for the day?
(i can still believe this one)

So in which context is your "peak" used ?

Zeestone99; I am loading for you !!!

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by makavele: 3:14pm On Nov 27, 2017

Dam5reey:
I disagree with that... 220 Panels 140 + 80 has produced 201 watt peak going to the battery..CC is PWM In July... So he should get close to 100% on bench test

201 n 220 about 91% . . was it sustained or instantaneous . . if the former? how long?
Also if it's a PWM; i won't believe the numbers except for a high-profile PWM manufacturer . . why?
Had one chinko PWM that would always cut off at 31A and stay at 29A. it would try to go over 30A again and cut off .
lead me to believe more amps could be delivered ..
Only to install a better and trusted CC that had never even registered 25A max.
Tested with a multimeter to confirm !!!
PWM be giving me false hope !
Thanks

Now I have come to that realization. I should have added more panels to compensate for the inefficiency. Today, I am doing roughly 55%. So many thing to learn

55% is not so bad; depending on weather conditions though.

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by makavele: 2:37pm On Nov 27, 2017

olagunju2000:
Thanks for this insight. Actually, the solar panels are in the open like a car port with flat roof. No shade and ventilation should be ok (my thoughts).

Still not gonna get past the 77% mark grin

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by makavele: 2:19pm On Nov 27, 2017

olagunju2000:
Thanks Makavele, Charge controller is supposed to be an MPPT according to the spec . I will check each of the panels as suggested and cabling as well.

One question in my mind is, on a sunny afternoon, if I measure both Voc and Isc; Am I supposed to get values close to the panel spec VOC = 44.3, Isc = 8.93A?

Thanks to Bigrovar . .

you would never get close to the panel specs . . at most 77%; if you're lucky

no matter how the sun shines . . .

as a matter of fact; too much sunshine + poor ventilation = too much heat = reduced panel performance

Good day house. Please i need your help to help review my setup as I am getting not up 60% of my installation capacity

I have the following

1) 15 pcs 300W mono solar panel (3 in series and 5 parallel)
2) Panel Spec:- VOC = 44.3, Isc = 8.93A, Vmp = 36V, Imp = 8.33A.
3) Based on the connection, Total V= 132V and I= 44.65A(Voc and Isc used in the computation).
4) I have a Master Charge Controller: Max 150V and 80A (48V system)
5) Battery setup: 24pcs of 2V 600A batteries connected in series to produce 48V.
6) The setup was installed 2 months ago.
7) The highest generation seen has been 6.1Kw/day on a sunny day.
I leave at Ajah area of Lagos
9) My Depth of discharge has been around 65% until last week when I was advised to use more to see if it will boost the production. I increase DOD to 45 - 50%
10) in Real time, the maximum that I have seen is 2400W.
11) Installation was carried out by a professional.
12) I check for loses, I am only losing average of 100W (comparing power from solar output measured under the solar shed and Controller output)

QUESTIONS:
1) my total installation capacity is 4500W (solar panel), out of which I am getting max of 2400W. Is this normal
2) Is there anything wrong with my installation.
3) The power generated has not been sufficient to charge my batteries. Is there a way to improve this

Please help

Speak to zeestone99 (08117398294, 08033913155)
Thank me later !!!

none of the batteries in my 48v battery bank setup has failed prematurely - yet
and this is going 5yrs and still counting. my first setup of only 4pcs 200ah batteries went 7yrs before I changed them out. I have a feeling these ones will surpass that milestone if their present superb performance is anything to go by.

You can say that again . .
batteries, if adequately pampered; will last a great deal
be it a 12V ; 24V, 48V, 96V, or 100000000V setup;
