Jst check if ur mppt has a nominal voltage of 12v, if ur panel is 24v,u can connect ur panel in parallel or even series two 24v as long as it doesn't exceed the max input voltage of the cc(usually btw 100v to 150v).the Mppt ll tk care of the rest. Also check ur nameplate to mk sure u r nt exceeding the current ur controller can dish out

I'm just about to do the connection.

I just got panels, but was confused about the capacity of the charged controller to buy.

We are fixing next Saturday, that's why I need advise

Poor camera in 2017

Dam5reey:
Yes, this will make your battery system 24 Voltage.. and capacity 200Ah.. Rather than your 12V 400Ah.
however, you will need to change the Inverter to 24V..

Since your Panel is 800Watts.. you can use a 24V 40A MPPT controller, which will take 1040Watts panel at 24V

Good morning

For now, I do not intend to change inverter
How best should I go about my

1000 watts
12 v

400amps battery

800 watts solar panel

Mppt 40amps charger

Dam5reey:
In this case.. PWM will be a waste of resources....

For better efficiency.. if you are not looking at cost go 24V battery Voltage system with 40A MPPT controller....

Your 800W panel will provide approx. 60A @ float charge of 13.8V. you will spend more in this case... Since 60A MPPT controller is required...

Go with first option.. otherwise​ you can go with your installer,

Does the highlighted mean battery connection should be in series rather than in panel as currently is?

Dam5reey:
Alright.. don't complain about performance after installation sha....

What is the PV system watt and battery system Voltage? The installer might have his points..

What other points​ did he mention aside 4 panels?

See my response below

Inverter is 1000 watts 12 v

2* 200amps battery
Connection in parallel

Intend to use
4*200 watts mono Frame panels

You guys can advise better

Thanks all

DMerciful:
Unless u re OK to loose 30%

DMerciful:
Use MPPT......Mppt harvest Ur 25%-30% more than pwm. Its the latest on charge controller technology... Its like Comparing CNN with NTA

Thanks.

I was told to use PMW, since I don't inter to use more than 4 panels

Football enthusiast ,I've 3 metre dish which can solve your problem of where to watch Epl and some other leagues.I've gotten 4.5 metre that is the reason I want datch it out,if you're interested you can reach me on my WhatsApp:08053054300 or simply call 08022045276

How clean and what's you price?

Yes o. Dey su can dan

Wan naijiria

Hello house.

Please advice.

Between Mppt and PmW charge controller, which should I use and why?

Thanks

So to seek a right of secession is a declaration of war?
Don't you get it, we are not compatible

You're missing the point.

Ojuiku declared war and not gowon. Ojuiku 'perceived' marginalization and chose to go to war

This guy should shut up.

The lanre Osibona he mentioned is my Uncle. He should shut, all he said are twisting the facts

Evablizin:
Lols Dino the truth sayer,the man who fights corruption with his anti-corruption book continue

If you're clean, you need not fear arrest.

Fanikayode has been abusing APC and buhari almost everyday. He has not been arrested for treason, but he's facing charges for collecting money.

There's freedom of speech, but there's no freedom for corrupt people

deji15:
I really can't understand why they always believe in the alternate facts when the truth and reality stares them in the face.

If greed didn't push ojuiku to war, then no one would ha é been starved. Before the war were people starved to death? After the war were people starved to death?

So, without one man starting the war, no one would have been starved

new2020:
How I wish that Awolowo did not starve 5 million Biafraan children.

Ojuiku starved them, not Awolowo

Yes I will, except if Osinbajo decides to run for office.
Aside buhari, which other candidate is better?
Atiku? Elrufai? Kwakwanso? Gej or who?

Can your president do this?

Rubbish and attention seeking thread

Fayose the eye service governor does that
Politicians when seeking office goes to the street to buy roasted corn.

So what's the big deal?

Current president of Nigeria now is Osinbajo, whilst OBJ is the vice. As at today

Car cannot cash coold again? Do they now have feelings?

Its the body, which is metallic that gets affected by weather and moisture

So he is this talented?

Dialogue and kudi or ego at work

I heard that the Niger Delta Avengers were given $10m at first, during initial negotiations and thereafter they agreed with the government on how much to be paid monthly.

Note that this special arrangement is between the FG and the Avengers and not part of the usual Amnesty budget.

Yes, it was dialogue and settlement.

You can see that the avengers haven't coughed for over 6 months, cos their lungs have been blocked with $$$$$

Nice one.

One of the reasons I like Yoruba people. Many of them are so detribalized. Let's see this

Igbo
Nedu OAP, Lilian Esoro,

Middle belt/ Niger Delta

30m??even some yahoo boys have more than that in their account....or maybe u meant 30billion

Don't mind him. Davido's house is worth over 100 million in Lekki, if put up for sale today today

Nice one

Hope none of those opportunists will claim its their money again, except they want to claim they own Lagos patapata

more like erosion and not collapse
