Funny, hahaha. It's definitely crude oil! Palm oil bawo...

Okomu dey move na

Time will tell. My bet on gold is paying off nicely. I'm currently betting on a rally in oil

Which of the oil though, Palm or crude

primehero:
Please which broker are you using to invest in Nigeria stock exchange

I use meristem though their charges is kind of high but they have good service

ojesymsym:
How do you set up this raspberry pi, I get idle pi 4 when de idle that I can deploy. Any link to a tutorial?

I hope I don't get picked up by NL bot here is the link to the solpiplog with all the instructions: https://github.com/njfaria/SolPipLog

odimbannamdi:
Which app/software is this? And how does it sync to your components (batteries, inverter, panels, etc)

It's the mobile version of emoncms that basically reads data from the emoncms on on my raspberry pi, the emoncms receives data from solpiplog for processing which inturn hervest the raw data from my pip inverter and BMV.

Oshomo12:
My brother, pls never use that figure to work. Use the VOC on the name plate. If and if u just for a second or two, u see 38v, what happens after that?
I have seen that quite well on 255w trina

You are absolutely correct my brother!

funken:
I currently have 9 (250W) panels in a 3S3P config mated to a Fangpusan 150V-70A charge controller on a 48V battery bank. I am thinking of adding 3 additional panels to this. Which is it safer for the CC - to have the panels in 4S3P OR 3S4P configuration?

Would have preferred the 4S3P as the cables I have already run can take the additional panels and I wouldn't want to be running additional cables to my cc.


cc Niyiomolade, earthrealm, ceasar, ojesky, spartacus11

When I was using a 250w Panel max I got was 34v so I think you should be fine with 4S3P but 3S4P is certainly safer incase your Panel voc is higher than mine.

Edit: I guess we were all posting simultaneously, lots of support in this thread.

deepwater:
But you know you are just a stupid person ?

Am sorry for engaging initially, constructive criticism seem not to be your goal. Your statement above tells me you are at a different state of mind.

deepwater:
See how people behave
Pay them to drive your car to you destination
They turn the car to kabukabu before it gets to the owner.
Other people will enjoy the car before the rightful owner.
How are we sure you dont steal the car parts since you are already using it for interstate journey?
One thing I was tell people, stat away from anybody who hager prices for no reason.
They are poor in spirit, body and soul

My brother some drivers are like that, even if you tell them not to, they still do, there are certainly drivers that don't and for those ones a higher price bargain is due.

Edit: I just noticed your insult on another post of mine.

izzou:
[color=royalblue]I come in peace too, sir

I did not say his 100k is fair. It's just an estimate he did. But you saying 50k max will send a wrong belief on prospective clients

An i4 and V6 have different fuel consumptions. Condition of the car also matters. The driver will still be settling. Obviously take a public transport back to Lagos and still have some profit. How can he achieve all of these inside 50k?

I no be driver too [/color]

Did you not also consider that saying 100k could also scare people thus sending a wrong signal as well, a range works better in such situation.

My intention is not to discredit the op (far from it) and I hope he knows that, it's just to indicate that it can be cheaper. 50 to 100k is what is a safer estimate.
As to how 50k will be sufficient while driver still makes good profit, well unless the car has no free space in it, but I will leave it at that as my intention is not to go into such details.

izzou:
[color=royalblue]The farthest Eastern state from Lagos is Ebonyi, and you charge 50k for it

Then how can Abuja that is farther than that, be less than or equal to 50k?[/color]

Bros am not a driver o, am just talking from my experience using various drivers, it can be more than 50kv a little but 100k is a lot. That said, one man's food is another man's poison, and the sky is sure large to use various drivers to fly. I come in peace i beg no vex

izzou:
[color=royalblue]50k max

That's too much naa.

It should be about 25k to 27k.

You overestimated too[/color]

My deliveries to Ekiti from lagos has been 25k, my deliveries to the east has been 40 to 50k.

amdman:
100k should get it from Lagos to Abuja

This one na over estimation, should not be more than 50k max

I like the fact that the inverter did not seem to increase its fan speed at that load, though since it's 5kva, the load would be about 30%, nice to have inverter I must say!

earthrealm:
The poor performance of the Ac, maybe mechanical.
Perhaps it has a leak, and needs topping up.
Why not get an ac tech to look at it.

From what my chinese yingli panels are producing, i passed up the chance to buy 350w canadian for 50k, and went for yingli 320w @ 44k....sounds crazy huh..
[b]For a 1680w array to hit over 2kw instantenous production, [/b]am yet to hear such from a canadian panel user.

I think we've discussed this, you were just most likely lucky to have received a wrongly labelled panel, on the positive side though

Based on competitiveness, price & functionality.
Mpp& Sorotec appear to be the kings, phocos coming a distant 3rd and then this your Deye.

What's the price range of Deye because I think it's features may actually floor that of MPP.

Only time will tell how they hold up over the years.
I hope anybody buying these high pv input hybrids hol im side knowledge wise...cos these half baked installers will connect 3s4p for you..sending 100v to a n inverter that requires 120v minimum start up voltage..and then turn around to tell u that...
Oga this inverter wey you buy no good!!
Return am

Hahahaha.....I also hope that someone planning to buy those high PV inverters will not be working with the lower band (120v) you should get at least 250V PV before you can get a good use the inverter. There is no start small small in high PV inverters o

chris81964:
The battery communicates with the inverter. So it does tell the inverter. The inverter consumes about 50 watts.

That's quite fine for a 5kva, how about the efficiency part i.e when a load of AC 500w is put on the battery, what does the inverter reports as consumption? With 500w AC load on mine, the DC consumption is about 570w to 580w, so it consumes more as load increases...even though no load consumption is about 28w.

Edit: noticed a typo on my stats it's 570, certainly not 670

chris81964:
My brother they are blowing my mind. I retired my Victron and Schneider products. This inverter and battery are IP65 rated. The inverter has a 120 amp AC charge and a 10 kw surge.

Okay this is interesting, one man's food is indeed another man's poison. Are you able to check consumption directly off the battery? If yes, what's the DC power consumption with an AC load of e.g 500w and the no load consumption?

spartacus11:
[b]Many in Benin don't even know what is lithium batteries, [/b]engage with different installers they where telling me they only use tubular batteries that it is the best.

On the CC u are right all they know is charge controller

I just told them their customers dey try

Not just in Benin my brother, it's generally across the country. I started procurement of extra lithium accessories whenever I placed order for my use with the expectation of selling (at 15 to 25% profit margin) to those who needed urgently and can't wait for overseas procurement.
Let's just say I may have overestimated the demand o

Sample of what a poor hervest day can look like, sun was not smiling at all

chloride6:
Good day,

Please who can help me with specification to build a small inverter system. Inverter and two batteries. No solar in the system for now. It will all be powered by mains electricity for now. Maybe Solar will be in the picture in future.

What is important to me is that I have an inveter with like 3kva capacity, cos I plan to gradually increase the amount of batteries i have because I plan to occasionally use 1hp AC and microwave in future.

I'm asking so that I dont fall prey to unscrupulous installers.

I've read the thread but so many terminologies to catch up with.

What is a hybrid inverter?

MPP?

12v vs 24v?

What brand should I go for?

Lithium vs Lead?

So many questions.

Thanks

- hybrid in this part of the world has both solar CC and utility Charger in one inverter
- that's typically the battery voltage options
- it depends on your budget
- I am always inclined to lithium so my opinion may be biased
- Some of them has been answered in the thread as well

Overall I will suggest you get hybrid inverter if you plan to upgrade gradually

IYGEAL:
That's what I thought too. I guess it's still using the voltage of just one of the panels.

Please get me clarified on how this 2s2p arrangement is practically done. My suggestion was that the panels be divided in two, each of the groups be connected in series and then the series arrangements be connected in parallel... Is this correct?

The attached picture is 4s2p that's to give you example of how the wiring should look like.

IYGEAL:
Progress report...

So I hired someone to climb the roof to rearrange the panels. He connected two in parallel and two in series and the two arrangements in parallel. I was a bit confused. I thought he was supposed to connect 2 in series, the other two in series and the two arrangements in parallel; he said it's the same thing.

Open circuit voltage of the panels are 18.0V. 8.3amps current.

I have a multimeter and tested the connected panels (disconnected from CC) they read between 18 to 20V. When connected to the CC, it's showing between 15 to 17v; and this was in the afternoon when the sun was supposedly at peak.

I think this may not be right.

If that is the rating on each panel then after the 2s2p setup your multimeter should read above 30v (18x2) unless it's not sunny or you have significant shading

chris81964:
Time of use and cooking with solar power. I cook lunch an dinner on my solar. Now I run 2 AC to get max production. I intend to double my batteries and PV. Enjoy the video

https://www.youtube.com/watch?v=pcxTDrOY9pQ

I love the "time of use" feature on the inverter, in my case I use solpiplog to schedule that for my inverter. What kind of cooker are you using that is consuming 1.2kw? Is it the typical ones as I think those consumes more than that?

ceaser:
NB: I realized my wattmeter may have recently been overestimating recorded consumption by as much as 12 watts. So I relied on the reading on the inverter which has been tested against at least four different appliances with good reproducibility of result.

So I recorded 102 watts on the 319L inverter freezer (nameplate 115 watts) this morning after it worked for 36hrs non-stop. Then it increased to 115 watts when a bucket of fresh unfrozen fish was put inside. One hour later, it had dropped to 113 watts.

Tell me more about that inverter freezer, thermocool? Or LG?

PETERiCHY:
Hope you know INTBREW has a negative EPS of -35k per share

NSE eh.... My brother even with the significantly reduced revenue from seplat people are still gunning for it, look at neimeth as well, plus uacn as well. Make intbrew move a little bit o based on other speculative factors and not on EPS

This Intbrew will not kill person o.... It's still digging for oil

IYGEAL:
Thanks a lot. I appreciate.

PS. By the bolded, I guess you meant 3s3p.

Nope with 6 panels it's either 3s2p or 2s3p

IYGEAL:
Thanks.

In simpler terms, you mean I should continue with the current arrangement (4p) instead of 2s2p since I use 12V?

Am saying you should reconfigure to 2s2p so you have early wake up and late shutdown

morning bosses in the house..
Abeg me sef want join this solar geng ooo..
My calculated watts is 900watts for at least 10 hours everyday..
I need the list of materials to buy (solar panels, inverter, charger, battery)..

I don calculate Taya.

@eleojo23 has said it will, before you go on this project you first need to be sure that you have at least a six digit budget. However there may be a cheaper option if you are only targeting 10hrs max

If we factor in 0.8 inverter efficiency that's at least 10.8Kwh of power storage that will be required assuming the 10hours is from backup and that will require 400AH of 24v Lifepo4. However if we can factor in 5 to 6hrs of sunlight then you can comfortably reduce your battery capacity by half. The following should be sufficient

- 270w panel 9 units
- 200AH Lifepo4 or 400AH lead acid
- 3kva hybrid inverter
- connection accessories

With a a little above a million you should be all set-up.

Disclaimer: These are rough estimates

IYGEAL:
Thank you.

Although I'm still curious if that would mean reducing the total wattage to 300W and then less charging current. Or will the Wattage and charging current remain the same irrespective of the arrangement, with 24v advantage over 12v?

You have a single 12v battery so the CC will charge based on 12v peak even though you have 600w total so yes it's a disadvantage. When you have 2 batteries you can have them in series to make 24v to take full advantage of the CC charge current and maximize your panel hervest

ceaser:
Why don't you just shop for it on AE?

I got two units about three weeks ago 29k apiece but used DHL option. Got to me in 12 days; no customs charges. Shipping was I think 11k with DHL option compared to 5k with the regular shipping which is complete wack at the moment, thanks to COVID.

You may have DHL issues with your location though. Seller says some DHL- designated remote locations will require extra 45 USD charge aside the 11k shipping charge. One thing I also didn't know then was that you can negotiate DHL shipping fee with the seller which is something I'll never forget to do henceforth.

Yeah the uncertainty of customs charges with DHL was my concern. I may have to go that route eventually.

Abeg if you go do am that way, you fit hep me find 14s Li-on 18/65/0 30amp BMS hide for inside? . I ordered one last week but with regular shipping. And the way regular logistics from China is going, it may not arrive this year.

Lol okay, I have ANT BMS on ground for sale if you are interested, though that is 320A

Are the table fan and standing fan of the same blade diameter? Please feedback on the fair consumption that may make it desirable over other brands.

The standing is 12inch, the desktop I think it's 9inch but they both have 12 speeds and at the highest speed it's 30w on name plate (was about 28 on my inverter AC readings will check with my wattmeter). It also has room temperature

Meanwhile, got a 12v orbit fan installed a week ago, costs 12k. Three speed and works fine so far. Strictly connected to 12v DC for now, I intend to connect an external AC power pack to measure the consumption later as the inverter freezer is monopolizing the wattmeter at the moment. The nameplate says 12 watts though.

Will be good to know how well it performs at the highest speed.

IYGEAL:
There are those stickers, but the panels are on the roof top now; not easily accessible.

The CC, it is 12v/24V 30amps. I just snapped the part with more info.

Max PV voltage is 100v so you are very fine with 2s2p set-up
