omo i yaff give up, mek dem continue with whatever works for them...........................hope newbies, wouldnt go and copy wrong info

if you can tune in now.
morningstarcorp is doing a webinar and this pwm/mppt issue is being thrashed out.

I tell u. We deserve the leaders we get

realestniggah:
Rubbish

Nigerians channeling their energy toward the wrong thing

Sowore is there they forgot him.. It tacha that need our blessing and support

SolnergyPower:
I have done both connections.

Oshomo12:
Let me help out a bit. Ur 4*150w=600w @ 12v ABI?
So if ur panel orientation and cables are rightly "placed". @eff of 80%, u should not get anything less than 35A at 14.2v. anything less than that, u re running at a very big loss with ur connection. Just parallel the four panels and revert to the house(to share the good news)!

SolnergyPower:
Overload alarm? You may be talking definitely about something else.

What I wrote was, as long as the PWM Charge Controller allows for it, I will always input as much voltage as I can from the PV.

This means, for a PWM that allows for up to 50V from the PV, I can do a series connection for two 150W, Voc, 22.05V in a 12V battery bank as against doing a parallel connection. From experience, the series connection has yielded me more harvest than a parallel connection.

I have come across MPPT charge controllers that ONLY allow matching PV voltage closely with the battery bank voltage.

Like I have always noted, I will always aim at the roof for a PWM as long it is allowed.

Thank you sir.

SolnergyPower:
Sir, where exactly in my claims do you need understanding?

SolnergyPower:
Indeed! Oga, take your time and take a second look at what I claim.

My claim is a personal experience in the last 6 months or so.

ojesymsym:
Are you sure of this your number 2? We are dealing with a pwm charge controller and not an mppt.

I think you are wrong. If they are 2 panels and the system voltage is 12v the panels have to be connected in parallel not series.

Lantern042:
Rightly said bro, Location is very Paramount when setting up a new business, it could make or break the Business. That's my predicament at the Moment, right now am just Wallowing in regret.

ceaser:
Li-Po or Li-on 18650s?

Sirvingeo:
A year plus 5 months . I am even lacking behind self because my laptop developed faults, for like 2 months I could't code and plus Nepa issue . I would have gone far .Nigeria is really very frustrating but i know i will surely live this shit hole country .

Sirvingeo:
Backend : python is my primary language .
Front-end : html, Css and JavaScript

Sirvingeo:
It's simply because of its mathematical concept. I will continue coding until I die and mine kids will take over from me . Although I started coding late at around 26 years and I'm 27 now

WHEN GUARDIOLAR WAS SETTING RECORD OF 18 CONSECUTIVE WINNING, DID HE WIN THE AWARD BACK TO BACK?
abumeyang won the best player award for last month and my question is WAS HE BETTER THAN KELVIN DEBRUNE?
There is a strong conspiracy theory that FA, UEFA, MEDIA ETC, are working to bring city down by distabilizing city players mental psychology- making the play feel that they are being hunted and their effort at city wil never be recognised by others, judging from ballon dor etc, not a single city player despite 3 trophies.
Even a harmless joke between two childhood friends has been interpreted to a racist slur by FA, thereby slandering bernados name and that has affected bernado mentality and his performance to the benefit of liverpool, what a dirty game.

Because of hatred for city, the best player ever to grace EPL (david silva) wil retire without ever being recognised for his effort, not even EPL best player of the year but van dirk and salah have all been recognise despite one seasön wonder with one trophy

uc4uandc:
We all know what will happen.....We just cant wait to see the look on the faces of Liverpool fans

Olalan:
As expected just hope they won't slip as they are always know for

spiritedtete:
Yea... i agreed with you... but as at when 3310 came out it was one of the best ..and was a fine luxury.
