My discipline makes me to doubt stuff like this. But sometimes, the Wright brothers experience makes me to sometimes give them the benefit of the doubt.

Yet many Chinese products, including many inverters we rate highly here are produced using "backyard process" only thing that guaranties "repeatability and reproduceability" is factory automation. Even in the far east it cost a lot to have fully automated factories only tier 1 solar companies can afford them. Majority of Chinese producers carry out most of their manufacturing in dingy, basements or old farm houses.. many no name black china products which floods Nigerian market are produced with little quality control yet they don't have the issue the Nigerian manufacturer have to deal with like power, lack of basic infrastructure or trained man power and a vampire government. The lad here might not have the scale to mass produce but this thing takes time. Let him show us what he has done first.

Yeah I agree with u...

Solar/inverter is d way, check my sig for enquiries, it's a win win for u nd ur neighbors... Cheers

Shygirl1989:
i concour with you totally. when feminisim started in the late 20th century,it was to give women equal opportunities as men not necessarily making them the same as men. whether we like it or not,men and women have different roles to play in the grand scheme of life,we are all unique in our different ways,we were created to complement each other.
the recent wave of feminism seems to stem out from women who want to "eat their cake and have it", they want to live as they please and not be held accountable for it. its surprising that Nigerian feminist want to be independent in all ramifications and still require the men to pick their bills,propose etc. ladies lets be realistic,open your eyes and ponder this decisions, i'm all for equal opportunity for everyone,male and female,but let's not shoot ourselves in the foot by pushing our men to the wall and end up regreting our actions in the future.

You spoke well, will u marry me, I'm tired of slay mama's with empty head.

That is why I look at people shouting "entrepreneur is the way". OP after my masters I obtained a loan to start frozen food business, luckily for me I have a shop, freezers and diesel generator. Sales was so low, it was as if people no longer eat in Nigeria, plus the epileptic power supply affected the market, when the product gets soft people won't want to buy it, and they also don't buy in bulk because of light issues too. The cost of fueling generator just to ice and maintain the temperature of the product to required standard is outrageous (10k in 3 days). I ran at a loss every single day I opened the shop, till I eventually closed down the project, now I am in serious debt with the facilitators on my neck.

I tried poultry and catfish business, that was is even worse, everyday price of feeds was always going up, same story.
All this happened between January-July, just went back to my cupboard, dusted my certificate and joined the pool of "I beg to apply". God help us in this country.

Many thanks Mr Olagunju and you are welcome too.

With the pictures you have shared most of the house would say your installer could have done a neater job with the wiring cleanup especially with the changeovers/knife-switches inside the house but this is just aesthetics in the end

I also observed that he did not use the modular MC3/4 connectors to connect the panels in series and then parallel - to my eye the way he spliced the panels' positive and negative cables to the main trunk lines may not make for a firm mechanical connection - just something to check - if you could isolate each series string of panels and see what they are doing with a volt and amp meter and see if any string is doing much worse or lower than the others - further in the evening or after disconnecting panels from CC, try pulling the spliced wires apart - they should give no 'play' whatsoever i.e shouldn't feel loose.

The good news is that panel heating up and reducing output should not be a big issue in your scenario - you will also enjoy a cool shade under the panels in the afternoons.

I think you are pretty close to getting to a good place with your system - with a few wiring tweaks and a solid charge controller you should soon be smiling and reaping the benefits of your system.

One last thing is to check if your batteries are behaving close to spec i.e 48v 600ah - do you have access to a battery monitor? or you can just run a known wattage load for x hours and see how the batteries hold up - it may be that your batteries are lightly cycled given such a huge bank and the CC is just floating most of the day - but again in the pictures I saw the battery voltage at between 48.sumtn & 49.sumtn which is not a good sign so early in the night as it means they were not fully charged during the day or have been quickly depleted after sundown.

Are you simultaneously charging with PHCN or Generator during the solar charging hours? Is the surface of the panels clean and relatively dust free (if not wash them). Is the house or other object overshadowing the carport and shading the panels?

Just looking for what random factors could be limiting your yield

NiyiOmoIyunade:
I have been following the intensity of today's posts with keen interest and I must say I echo you BigRovar!

My MorningStar TS-MPPT 60A is connected to a 4.5kw (15 × 300 Mono Panels) array just like Mr Olagunju - my yield today was 17.77kwh in Lekki. Lagos State and this was an average day with quite a few cloudy intervals.

This underscores the importance of a solid charge controller as I routinely do 21kwh daily yield on a good day when my batteries are deeply drained.

Please bear the following in mind - my panels are West facing at a ~30° slope so by no means ideal yet I get these results with a solid charge controller - I made custom settings to throttle my controller max charging amps to 55amps - it will routinely hold 54.4amps from 1pm to 4:30pm with only brief rests at 40sumtn amps when there is a lot of cloudy skies.

When I had my chinco EP Solar on this same 4.5kw array I would get say 45 amps very briefly as peak but EP Solar would generally stay around 39amps - the only thing different between 39amps & 54amps yield is a solid MPPT charge controller!!! - 15amps improvement and remember I am throttling the morningstar controller output to 55amps via custom settings so as not to boil my batteries - I have seen it easily hold 58.sumtn amps steady for 3 hours plus.

So that's it - Mr Olagunju probably needs a proper charge controller if everything else checks out - currently I disconnected my second array of 1.8kw which is connected to the EP Solar - I am keeping it as backup for when the rainy/cloudy season comes.

What u r trying to say is better soup na moni kill am.

Dam5reey:
We are saying the same thing...

My point was the importance of rating at the back of Panels VOC, ISC, Imp Vmp and so on.. thanks

I occasionally use my 1k watt Inverter for Ironing, I understand all your points

Yeah noted, it's all important... Cheers

Dam5reey:
yes I'm aware but 1kw should be able to do 800watts conveniently.. I only made an example.. why ratings on appliances are important


I'm not talking about Chinese ratings... That will rate the Inverter it's peak power, instead of continuous power, those are the Little things we should take note when buying electronics.. cheers

That's y u got it at a cheaper price, if u want the one u r talking abt, u ll get it four times the chinko price, instead of blaming the chinko, get a higher rated chinko, or quadruple ur moni and buy a U.S product, trust me if you do the later, fear won't allow u load it 800w sef ... Hp u get my point

Dam5reey:
After checking through this https://pvoutput.org/list.jsp?userid=46221

Seems he does not need to worry to much... Unless he has spare cash to get Better CC...

He still needs a cc for upgrade, so he can't escape the cc tin

emmaniche:
House please help review these inverters. Thanks.

Emerson CP 70i 01 20 KVA 110V Inverter

Kevin DSP Sine Wave ALBS 20 KVA 240V Inverter

U ll shoot ursef in the leg using the Emerson, as it does nt support our country voltage, while Kevin is an Indian brand, it uses more ba3, as opposed to the normal 48v,wch means more backup but ll giv u headache if u want to go solar,... Why don't you try our Felicity inverters, with good customer services, warranty, and service centers here in Nigeria. This ll giv u ease of repair services incase anytin happens(they are fast abt it too, I took an inverter there, and it was repaired or spot without charges, jst under 40mins).

Call/watapp 08117398294 to order... Tx

olagunju2000:
Thanks to everyone. All your your argument are very robust and I really appreciate all your thoughts.

My real concern is that I only get about 2400W max instantaneously out of the total install capacity of 4500W. I wanted to know if something is wrong with the panels. I have learnt a lot today about what I need to check on the other elements. The last enquiry is that how am I sure that my panel is doing what it is supposed to be doing. I wanted a way to validate that the problem is not coming from the panel itself. So, I wanted to find out from you experts, if I can validate the panels by checking the Voc and Isc on a sunny afternoon and comparing to the ratings of the panel. Based on all your experiences, will I get a reading (using multimeter) close to the ratings of the panel if the panel is ok ? Or is there another way of finding out if the panels are ok?

Thanks...

One step at a time sir, Wat we discussed is OK, besides u ll stil b needing the item for upgrade, so moni no waste

Dam5reey:
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...

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

At last, this is gud news...

EKPETI:
I love this interview Papa granted. My people, Education is expensive that is why a sane society don't leave in the hands of the capitalist. The truth must be told no public university or polytechnic in Nigeria is average let alone standard.

The fee of CU is worth it compare to the services they render. 24/7 water, electricity, quality lecturers earning well, research at ur disposal, infrastructures, well equiped library, good hostels, above all discipline at its peak. There is nothing u are looking for in schools abroad that is not in CU. I know u cant compare schooling abroad and CU fees.

Bishop Oyedepo said the church has not taken anything from the school since inception and I believed him.

I pray God bless us all to send our children to good schools to get quality education not what we have in our public schools in Nigeria. Do u knw that PMB removed food subsidy in the tertiary institutions in d 80s during military regime? Do u knw what it takes a private inst. to have 24/7 electricity for 18years alone? No institution in Nigeria can say that except CU. I knw u will say is it possible. Here this, my children will attend CU. I love it.

God will continue to empower Bishop David Olaniyi Oyedepo.

NB: Education is costly.

Pls can u educate us on the benefits of the sch n it's outrageous fees to the society, wht projects v been carried out by sch or students, Wat research, benefits of the research to the nigerian pple, cos Wat i understand here for now is that with all the quality education n research the sch boast, it all boils dwn to getting a job, wch any1 from any oda sch can get, it relates wit dat saying " at d end a lady ll always end up in the kitchen(I'm nt sayin dis it right)". So pls educate us.. Tx
