The way things are in Nigeria now,I would recommend a 100ah lifepo4 cells with BMS...lower cap but guarantee of at least 3years..thank me later.

Thank you for your recommendation. I am still enjoying my lifepo4 battery. Its been over 2 years now and it's still good.

Oga, save yourself, and your finances the stress and get that NEPA wire sold by omo`ibo down the street.

Yea that same wire that draws light from the electric pole to your house. The coating of the wire is ash in colour.

A bundle should be more than enough though that depends on distance.

Cost of a bundle, is so much cheaper than that copper wire advertised as solar cable.

That wire would handle even 4pcs of 300w solar panels all in parallel.

But please feel free to buy the copper cable if your pocket no get wahala

Boss please can you show me the type of wire you are talking about here. So as to know the particular one to buy

That cable / Wire that NEPA / PHCN cuts whenEver you fail to pay your Bills.

The wire is Ash in color.

Now fort hose using prePaid meter, they often use a different Cable / Wire which is Black in color.

That One that's Ash in color, is often sold in those Omo ibo shops selling electrical things down the street. Please don't buy in Yards because you would cheat yourSelf. Just Buy a Bundle. They have big Bundle (Full) and small Bundle. Most times, na the small Bundle dem go bring out tell you price. Ask for the bigger One.

The Cable is equally called Service Wire . The ones sold by in electrical stores down the street is mostly China, hence you need ask of madeInNigeria version.

low quality 16mm nepa wire for solar panels . God have mercy!

Kendzyma:
Hi Everyone. I have a 2.5kva setup with 2 12v 220ah tubular batteries (24v system), I also have 6 300w panels connected on series (not sure, installer did the whole set up, but the said it's in series) .

Issue is, I have been using a pwm 60amp cc with it for a while now that works fine, just decided to upgrade to powmr 60a mppt cc which I installed yesterday, but I have been getting an abnormally high temperature from the cc, like 60+, which the highest I have gotten from pwm was around 40. And I also noticed a reduced battery time when I am on battery compared to when I was using the pwm...


what could be the reason for this temp increase and reduced battery time?

From the PV voltage I suspect that the connection was 2s 3p. See if you can do 3s 2p to reduce the current coming into the charge controller. Would've asked if the cooling fan is working, but this design doesn't have any.

For Experience, this Particular Model of MPPT from POWMR Sucks at tracking... You are better off using a PWM... The controller is rubbish...
The versions with Fan are far better...

He is doing 6p based on the PV Voltage on the screen... It shouldn't even get hot as there is not much conversion...
3s2p/2s3p maybe hit or miss.. he can try his luck...

People want to save cost by all means not minding the effects.

Why didn't anyone mention that solar panel wires are so Damm expensive??

Jesus!!! That's expensive!

yemi2plus:

you people speak as if it's everyone that could afford those Copper wires.

See eh, when I meet those who could afford it, and require it, I use Copper for them BUT for those managing, that Aluminium is good enough.

Imagine you stay at ground floor, in a 3 or 2 storey building, and trying to pay ₦4,100 per yard. At end of the day, even ₦60,000 won't be enough for Cable alone, when the alternative which is good enough, would cost you less than ₦10,000.

I rather save cost here, since difference isn't that much, than try to cut cost buying inferior Charge Controller, Batteries, Solar Panels, etc.

Have seen those who used very light Cable just because they couldn't afford the required thickness, and you know what that means.

In some cases, I have had to make their solar PV in series to reduce the current BUT that wouldn't work in all cases because most times, even their chargeController, is almost at it's capacity limits.

Solar systems is meant to be Luxury, but situation of things in this damn country, have turned it otherWise.

isangjohnson:

so it's better buying inferior Inverters, charge Controllers, etc.

A lot of us condem or go along with things without [clear practical] experience.

Aluminium cables are only slightly lower compared to Copper of comparable thickness / size.

in other words, a 6mm Aluminium cable, is only slightly lower in conductivity, compared to a Copper cable of same thickness. In fact using Aluminium cable thicker than that 6mm automatically EQUALs and/ or SURPASSes the current & voltage handling capacity of the Copper cable.

when One understands the PROs and CONs, it's easier taking decisions.

Gshems:


6mm @4100 , 4mm @3800

now how much is 16mm of Aluminium cable ?

Have you compared % losses between them to know which PAYs you better ?

Let's not forget, that when used outside, Aluminium is LESS Likely to corode, compared to Copper.

Last I checked, I prefer that 16mm Aluminium cable, to 4mm or even 6mm of Copper.

it's even much better when going over longer distance OR when Carrying Higher voltage over long distance. Same decision NEPA / PHCN took.

yea, if you're doing 12-volts system, where current might be so much higher than Voltage, you could and should use Copper BUT then again, 12-volts system would only cost you more, while giving you so much less.

why did NEPA / PHCN decide spending and installing Transformers (which are very expensive) at every point, rather than transfering exactly what's required by utility consumers directly from the Power [sub]station. Yea, they just could have just used Copper, and deliver exactly what's needed by Consumers without the added cost of boosting it

Dam5reey:

3s2p/2s3p maybe hit or miss.. he can try his luck...

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 remember to set the battery type you are using

Good day,
Pls can you advice or give me a rough estimate to set up a solar inverter system ... budget is 850k

You no go pick calls, you no go reply WhatsApp mssgs. Which way now? Your CC still remain?

He doesn't depend on it for his income.
It is a side hustle. If otherwise, I bet you he wont behave like this. To keep to agreement? He will raise your hope and crash it as if nothing happens. It is in his blood. Yes, in his blood.

my own be say dem take light for over 24 hours and e no be natural disaster.

I am new to renewable energy but I see alot of solar setups
Please I want to ask for advice
Are all in one solar power generators reliable or its better to go for conventional setups?
I see alot on jiji ranging from 300w to 5000w

Jesus!!! That's expensive!

Thanks o. Got my cc delivered.

They are reliable but before you buy, check the datasheet of the inverter and the type of battery/capacity and compare with your loads.

jasp12:

Please rather than ask just a single person, better thow your question to everyOne of us. Then you take which you believe makes sense.

Should you ignore everyOne else, and focus on just a single person, even if the person misGuide you, dem fit punish you by keeping mute.

At end of the day, we are all here to learn one way or the other. We dey a rgue no mean say we know it all

for someone who's not just in this field for the money, and from experience since I know how they're Built, would suggest going for conventional setUps even if they appear slightly more expensive

even if One doesn't depend on something as major income, so long you're willing to collect people's money, you should deliver na.

na my issue with most of we Africans (case study: Nigeria)

it's worse the moment they've got your money. I've learnt never to put money into people's hands when work never finish even if they don't look hungry

Thanks for point that out. MeanWhile, the old version of that charge Controller, is much better than the new version.

Imagine giving MPPT charge controller low Voltage. na wetin e wan come track again

isangjohnson:

Theory may not give you the needed results in question 1. Tell us your loads and we will tell you the pv capacity that will power the loads and charge the battery to full in a day plus or minus.

2. Hybrid and non hybrid are durable, efficient and stable. It's a matter of choice.

3. Panels are still ok if you wish to continue with that capacity but that 30a cc is not good for 24v or 48v system.

Thanks sir.... Will do that and get back
