Okay..

It actually depends the VOC, ISC and connection (either series or parallel)

If your VOC is the same 350+250 will give you up to 580

I do get 200+ from 140 + 80 and not 160

Oshomo12:
What I 'do'?

Note: it's like u didn't get my point.

duwdu:
Congrats, davodyguy.

But please permit me, guys... isn't the total watts from the panels in this configuration not supposed to be limited to 270 + 250 = 520 Watts? Or, have I been missing/muddling up some of my lessons learnt? (Honestly, I'm relatively new to all of this.)

No involve niyi, jst block am 4 junction...

Oshomo12:
Over sabi dey worry u(I can't blame u though; it's a DIY thread where anybody can answer ur question), he specifically mentioned Niyi, u see ur name and others there?

davodyguy:
Thanks Chief

I hope its true lol

davodyguy:
Chief niyi, wanna ask a question.

When I was using 1000w 12v inverter with 540watts Panels via 40A CC on my 2*200AH batteries connected in parallel, the CC drops about 30A on the 400Ah batteries.

Now I'm using 2000watts 24v inverter same 540watts Panels via 40A CC on my 2*200AH batteries connected in series, the CC drops about 14A on the 400Ah batteries.My question is doe the CC adjust based on the battery connection or voltage?

pranil:
Out of curiosity, I asked Victron if their charge controller will survive without battery - Interestingly there is no issue even if the breaker trips

I believe Morningstar and EPEVER are known for failures any other which come with the warning not to switch on without battery

bigrovar:
OMG.. RED TEARS. The worst is the BN series of controllers. I once timed it for 4 minute before it recognised cloud change and perform a sweep.

agabusta:
Thank you for your responses. Which is to be clamped btw the red and black wires to check the charge current?

sinistrian:
Very little sunshine here too. I was waiting to boast of the stats generated by my morningstar
Anyway, the only thing i can say for now is that the MPPT sweep is very very fast - like once a minute, you wont even notice it. No more starting from zero like the Fangpusun 150/70.

agabusta:
I have a multimeter, will I just connect it to the negative and positive terminals of the batteries while setting it to DC voltage to check the batteries? And do I have to disconnect the batteries before the test?


How do I test the inverter itself?

GAZZUZZ:
A/c repair history since importation?

AZeD1:
Have you asked yourself why they are limited to the Southeast ?

Why are they not in Lagos?


You can watch EPL online but everyone knows the streams are illegal.

nonoski:
Yes I know the max wattage for flex max 80 using 48v system is 4000 watts like u pointed out but from what I gathered from this forum is that a 4500 watts system will most likely not do above 75% - 80% (3600w max) from my pv due to inefficiencies.
So I think I will be doing just fine

agabusta:
Please how can I confirm my inverter batteries are due for replacement. They don't provide much backup time like before. My Bro is saying he is suspecting the inverter is not charging it properly, while I'm suspecting the batteries are almost gone. Btw, the batteries are 200mah and have done 2 years.

ceaser:
Bro, I'm still temporizing o. Wanna get it all right and be dead sure before i start connecting stuffs.

NiyiOmoIyunade:
Tell us about it na!

Pics and a review would be nice.

This is a DIY thread afterall and we should always broaden the knowledge base.

Just to confirm, your posts have indeed been valuable to me.

It’s refreshing to see that there are still motorists out there that not only take pride in maintain their vehicle but also willing to pay a commensurate bill.

The Baba Latis may never reach financial freedom if they keep getting hosed by greedy clients.

I had my car worked on by someone in Ibadan. I forgot how much I paid but was at least double what he asked for because as an Autoist I knew what he had to do. Do you know that this man was working while wearing a colostomy bag? I donated in addition to his medical bill that day too. I also bring him tools whenever I come home. I brought him a torque wrench last time. The last time he used a torque wrench was back when he worked for RT Briscoe. Imagine that.

In any thing we do in life we have to fear God.

Please don’t stop doing what you are doing. Buhari won’t solve all the issues in Nigeria, it is us, the average citizens that will.

temmym4:
You are very rude and insulting. That shouldnt have been. But i pardon you though, i know your type

From your posts, one can easily tell, you have got a very high degree of PRIDE! infact you stink of it. At the end, when they check people like you out, you don't weigh a thing.
Those who actually own the wealth don't make disturbing noises.

You dont even know me, we have never met. how are u so sure i v got a financial misfortune and that you are any way a step higher than me.


At this stage of my life if i start going into that kind of rants with someone we never met in physical, then i am a f.o.o.l


Why do you keep tagging GAZZUZZ unto your posts anytime i quote you. lol.
Why not leave him out of your rants.
Must you put how much he charges for AC here.?

As a matter of fact 2 of my recent tires were bought from him and it was purchased at a very reasonable price.

Just as i posted earlier, not every Auto Engineer is unreasonable. I have worked with a notable brother here, Though he quitted Nairaland now ( His posts still exists here though). Old nairalanders active in Cartalk session will know him. He was very good and his charges were reasonable even when i was expecting him to cost a fortune when i met him, no major fix ever since he fixed the car to the point of bringing it down to the country and till i sold the car.

AC is entirely up to u. I "replaced" my wife's car AC for more than 40k (compressor,dryer, tinner, gas flush) and that includes workmanship of 9k. They didnt press button and billed that, they "changed parts" .

Now tell me, how does "changing oil as maintenance routine" relates to "FIXING AC"

Actually i dont have a problem with you servicing your car with your arms, lungs and whatever you so wishes. It's not my headache, it's yours.. But the issue i have with people like you is trying to impose your beliefs on others and condemning them.

I actually feel it s actually unwise thinking, because a mechanic charged 500 or 1k for changing Brake pads, it s a death sentence, while the one that charged you 10k guarantees life.

Brother, Learn how to be humble, embrace humility cos pride kills, even faster than AIDS sometimes.

Keep your beliefs to yourself, when you feel you need to educate others, make it minimal, without insults too.

Lastly, don't assume what you dont know about others just because they gave their own opinions. Humility doesn't signify Poor and Pride doesnt mean you are Rich.
Be mature. God bless u.

temmym4:
Say all u want bro. But that doesn't change the fact that your using almost 25k service charge (apart from the parts and oil purchased) just to change oil and brake pads is outrageous and wasteful. You think everyone are polithiefcians, looting all the resources and can decide to spend whatever they like? Hell No! Some of us work very hard to own stuffs.


An average Nigerian will own a used Camry (Not brand new) bought around a million, you expect them to spend half of that amount on the same car within a year just for a service charge to change pads and engine oil?
Who does that?

Am sure you pay 2000 naira each just to gauge each tires with an educated Vulcanizer.

Who says Educated Auto engineers don't make mistakes, are they God?

Maybe the so called Educated Auto technician should pull themselves together and review their charges so people can patronise them instead of hiding under being a professional and billing exorbitantly. This is Naija, not the US.

Truthfully, not all professional Mechanical engineers does that anyway. We v got some very reasonable ones.



Does changing only your breakpads with over 20k + service charges guarantee your own life on wheels?!

so it is the service charge of 500 naira paid to the mechanic who changed the pads that will cause the "Brake failure accident".



If you use 75k to do change oil and breakpads, i wonder how much you ll spend in putting a fault to order.
Automatically if u are a regular traveller and u do a monthly routine service. U would have spent 750,000 apart from fixing other issues within a period of 10months
If u dont have nothing else to do with money, bros donate to the needy around you. It will do u some good later in future.

Funny thing is, u will be surprised to find out most Criticisers here are the ones who visit Kazeems mostly. Some don't even know the road to a mechanical engineer's office or workshop.
Lies everywhere. That is what is killing Nigeria!

Not all Kazeems are incompetent. some just dont have the opportunity to attend tertiary institutions.

I visit Kazeem when i need to fix minor issues especially issues i can relate with, i even make sure i look up the issue online then wait and hears what he has to say.
sometimes he is busy and i wait patiently monitoring him doing mine or other cars, he might scan for codes, the name might feel strange to him since he he didn't go to school to study mechanical engineering, he searches via google image, gets the picture and works it out.

when it comes to major issue that i know will eventually turn a Kazeem into a guesser, i seek the help of the internet firstly then visit an experience engineer. Since i dont usually have major issues. I think proper supervision with my mechanic does it for me.

Felixtuta:
No be fight bro....someone richer has already paid the said amount.

God bless u.

EgunMogaji:
I see two issues.

1) Shrinking middle income: Folks do not want to pay a commensurate fee for services. Do they think Buhari is going to come and deliver money into their accounts? It's these commerce in between people that stimulate the economy.

2) Labor pool: because there is no standard, anyone can hang up a site under an iroko tree and call himself an engineer. So, of course, they can afford to charge N20 for an oil change since there's zero overhead.

It will take an act of God for Nigeria to reset.

Back in my youth, taxi driving was actually a noble profession as is most non "alakowe" work, but now every riff-raff that can't get a job is an engineer.

Then we wonder how seriously good cars and brands get to Nigeria and they become a bucket of bolts. I bought a 4Runner a while back now and one day I was looking around the engine bay and I noticed that the previous owner has removed the brake booster with all the accompanying ABS pump. Who does that? I'll tell you, it's a Kazeem and not Elizade.

EgunMogaji:
Please one more question.

If within the service area, would an offer of a free shuttle back to your home/office/school and back to pick your car back up when the job is completed of value to you? Or you'll rather wait in an air-conditioned waiting room with free wifi?

Thanks.

temmym4:
Bros. Relax first.
You paid 10,500 for to change an engine oil that costs 16500 seperately.

Your mechanic charges you 2,500 each wheels he replaces its Brakepads. So u use about 10,000 to replace brakepads that costs 35000
......

In other words, you actually used 72,000 naira to change oil and brake pads.

Waoh. I envy you bro.

God bless Your mechanic. He will soon buy a new car or finish his building project
