I bought mine mid January 6mm @2k


Correct, 4mm² shouldn't be more than 2.5k, them go dey inflate prices anyhow and put the blame for innocent dollars head.

Make them wait and see dollar crashing to 700 per dollar, then them go come online say na distress sales!

What's the price range for coupled battery 24v 1.5kwh

Am not sure I have seen 60Ah here.

Will suggest you go for 24v 100Ah, which will give you 2.5kWh.

Minimum 500k.
There is no way you can get a 220ah battery less than 280k currently, 1kva inverter like 100k, charge controller 80k, solar that one is on drugs right now. Wirings and all nothing less tan 50k. You go spend 500k sef.

Brand new 1kva inverter is at 170k now, where did you get yours for 100k

Just checked again. Thought the temperature is voltage. Lol.

Some installers are crazy. Why would an installer opt for 6p after swapping out a PWM? THAT'S the problem then, Kendzyma get your installer to go and change the configuration to either 2s 3p or 3s 2p. He did 6p which is the reason the charge controller is running very hot, low voltage and high current are often recipe to high temperature. Also your MPPT won't work well at such low voltage. That'll explain the poor yield too.


That controller is not bad, I have friends using it without issue, just to set the battery type you are using


Bro what is 2s 3p

Bro what is 2s 3p

2S= 2 s in series
3P = 3 s in parallel


Let me use the diagram below to illustrate 3S 2P

s 1,2, 3 are connected in series = 3S

s 4,5,6 are connected in series too = 3S

Then there is two parallel. s 1,2,3 is in parallel with s 4,5,6 . Notice the parallel connection between s 1 &4 (and s 3&6

s in series are connected + to -

s in parallel are connected - to - and + to +

PV Plus and PV Minus goes to the charge controller PV + and PV - respectively.

This client got an MPPT charge controller rated 40A and 520W

The set up is 1kva 12V

He has 2 set of 300W in parallel this is like 600W

Wanted to know my opinion

Told him the charge controller would not be able to handle the excess difference and might affect the controller. and even if the CC no get issue the excess is useless.


That’s what I think.


I would like you to share more technical reason boss.

WHATS THE VOC MAX INPUT of the charge controller?.
600w on a 520w max cc isn't an issue. few s generate at max. also you can over array by up to 20%--zero issues...the dangerous part is exceeding the cc voc rating...an that one dey fry cc

mvphenryeto5:


Bro what is 2s 3p
P means Series connection ("+" s with "+" while "-" s with "-" OR "Positive" s with "Positive" , while "Negative" s with "Negative")


S means Series connection ("+" s with "-" while "-" s with "+" OR "Positive" s with "Negative" , while "Negative" s with "Positive")

In Series connection, Voltage increases, while current remains same.
In Parallel connection, Current increases, while Voltage remains same.


when you see us write 2S3P , it means there are 5 (2 + 3) Solar s involved; and we want to connect 2pcs of Solar s in Series, while the remaining 3pcs of Solar s would be in Parallel.

That way, we enjoy both Advantages of Series and Parallel connections.

Would suggest learning basic electricity and if you want to go far (electronics) because such basic knowledge is required to have immense knowledge on not just Solar s but other electrical things. At least use Google. In our time, we didn't have such luxury. Just that I had the interest and was often idling around electricians

charge Contollers, just like most electrical appliances, have tolerance limits hence even when it says 520w on it's sticker, you could get away with feeding it slightly higher and nothing would happen.

Though, it's often better you never get close to it's limits on Sticker, let alone it's tolerance limits.


and you see that 40A of that charge Controller eh, ensure you don't risk it because if you near am and na overrated, or you am (assuming say na 40A true true), your charge contorller fit fry any how. And successful Repairs ain't guaranteed.

Also, Solar s rarely produce up to 90% of their stated output. That's assuming said Solar is original, not close to it's old age, and not overRated.

Also, hopefully you're very much aware even charge Controllers, arre over rated atimes. When one of my epEver charge controller (rated 40A) went bad, I temporarily bought a cheaper version (rated 60A) pending when they fix mine (which they couldn't) and guess what, the 60A no fit do wetin my old 40A dey do. Spoke with a top importer and the moment He heard the brand, He told me more than I thought I already knew

300w s Clearance sales

12pcs of ~300w for clearance sales @86k each!!

Reason for sale
Buyer begged a friend in alaba to help him get s and other solar devices.

Later buyer got referred to me by a colleague for installation.

Buyer got the shocker of his life when I analysed the s and told him they were relabelled to 400w. 😳

Now buyer wants to go for 550w s and needs to dispose these off at a great discount. s were bought at the rate of 110k

Location is ojodu Berger, but can be sent to any part of Nigeria.

URGENT SALES!!

What is the conductivity difference between aluminum cable and copper

ChatGPT
The conductivity difference between aluminum and copper cables is significant. Copper has a higher conductivity compared to aluminum. Generally, copper cables are preferred for electrical wiring and transmission due to their superior conductivity. Copper has a conductivity of about 58.5 × 10^6 siemens per meter (S/m) while aluminum has a conductivity of approximately 37.7 × 10^6 S/m. Therefore, copper cables can carry more current with less resistance compared to aluminum cables of the same size.




Can aluminum cab lure be used from solar s to charge controller?

ChatGPT
Yes, aluminum cable can be used to connect solar s to a charge controller. However, there are a few considerations to keep in mind:

Size of the Cable: Aluminum cables typically have higher resistance compared to copper cables of the same size. Therefore, you might need to use a slightly larger gauge aluminum cable to compensate for the higher resistance and ensure efficient power transmission.

Compatibility: Ensure that the connectors and terminals used with the aluminum cable are suitable for aluminum wiring. Some connectors and terminals are specifically designed for copper wiring and may not be compatible with aluminum.

Installation and Safety: Proper installation techniques must be followed to prevent issues like overheating, corrosion, and loose connections. It's important to use appropriate techniques and materials to ensure the safety and longevity of the electrical system.

Environmental Considerations: If the installation is in a corrosive environment, special measures may be needed to protect the aluminum cable from corrosion.

While aluminum cable can be used, many installations opt for copper cables due to their higher conductivity and lower resistance, which can result in more efficient power transmission, especially in solar power systems where efficiency is critical.

This can be ok for someone who is on a budget installation.

Before I installed my s on the roof I was running 3 of my 570w s with normal 2.5mm house wire to my inverter just by laying the s on the floor.

But to me it didn't make any atom of sense to spend over 3m to buy inverter, battery and s only to start cutting cost on wires that is not even up to 100k.

bassdow:



experienced person no go get issue with that. Also, even non-experienced person shouldn't have much issues with that.


That's hardly an issue. Worse case scenerio, you place something on top to cover it BUT I have never done such becase the coating is more than enough

reason why I said and made it very clear, I rather spend more on other MORE IMPORTANT things, before considering cable.

Moreover, that House Wire of 2.5mm is very very overPoor. No be that wire wey dem dey take draw light from iBetterMyNeigbour Generator ?

Cable me gan sef dey talk about get quality and difference between it and the copper cable no plenty. and you know what, some in bid to buy copper cable, ends up buying lighter ones because it's costly. A thicker Aluminium cable, is much better than a Lighter Copper cable.

and that Cable wey you talk say no reach 100,000 naira , fit 100,000 naira depending on distance.
