Mac2016:
When I see Nigerian youths that shd be bothered with working their asses off to place Nigeria back on track calling out fellow Nigerians herein saying Igbo, Aboki or Afonja, it makes me feel Nigeria has lost it! Nairaland shd pls do more. It's not about making money only, help foster unity. Your site shd not be used to fan the ember of divisiveness that's already at high level in this nation. Its not enough to sit back and believe cos you state it in your policy you can go to sleep. Ban flagrant tribal bigots/defiants. Place necessary sanctions
Cc lalasticlala

I agree with you, Quora and Reddit has millions of users, but just try and type a racial slur or something of that nature and see how fast the comments disappear and how quick it leads to ban! I think by turning a blind eye to the tribalists, the owner and mods are complicit in keeping this tribalism alive. Does it worth the extra traffic? No!

There should be zero tolerance for such behavior here. If every tribalists knows they'd earn a ban, they'd take their trolling elsewhere!

Thanks for sharing!
But we don't use all these voltage levels in Nigeria.
Can you help us with the ones we use in Nigeria too, please? (0.415KV, 11KV, 33KV others seem to be in your earlier post)

The higher voltages 11kv, 33kv are for transmission purposes. We transmit at very high voltages to reduce loss in power and be able to use smaller sized cables. The 0.415KV or 415V is the voltage you get between phase to phase in a three phase system. If you take one phase and a neutral you'd get 230V which we is popularly used in most homes. So most of the three wires you see along the road have 415V in between two phases. Transmitting for very long distances we often use 132KV for that.

Is it an accident or what,I'm interested in her story

Arteriovenous malformations (AVM) are high-flow lesions having a direct connection between an artery and vein, with bypass of the capillary bed.Those affecting the upper limb and causing cardiac decompensation are rare.

Treatment of such lesions remains a surgical challenge. Despite multiple procedures, total eradication is often not achieved. For some patients, limb amputation becomes necessary and carries significant risk.

Akin3891:
Pls, how much does it cost for a solar panels system that can regularly power two fan, one tv, 6 bulbs. It's urgent cos my family is dying of heat, and i hate the sound of Gen at night.

Well, the costs may be from 150k and above.

You can also invest in forex , learn to trade and trade with your smartphone.

Don't forget to mention that this venture can make you lose all you've got the same way it can also make you a wealthy person overnight. People going into it should know the risks involved. Peace.

Since the topic is not about BB Naija or something to do with tribe so that the tribalists can have a field day, this article is likely NOT to get the attention it deserves even though it's on the front page. SMH.

baugustine:
please am just seeing this but have seen people getting alart from this platform not one not two things is it still not real

Although I have no idea of the person you are referring to, but I just want to let you know that scammers are known to drop bogus positive and glowing feedback either by creating multiple accounts or through the help of the network of other scammers.

The hypocrisy, the blind hate, the self-aggrandisement will be the death of progress in Nigeria as we know it. Here I see people congratulating themselves for being the holiest or pious and hence the reason for the so-called low HIV prevalence. Have anyone taken out time to check if there is high precedence of HIV in any state of the country that no one is really safe? Do you know why polio is still in Nigeria? I'd tell you, some decided due to either ignorance or religious bias and belief not to inoculate their wards. No one is really safe from contracting any of this disease as long as there is freedom of people travelling from state A to state B.

Also, in everything statistics, you should take cognisance of things like people's ease of access to hospitals. What if state A has more people visit the hospital and is declared higher HIV prevalent while state B residents hardly visit any hospital?

Part of the problem of Nigeria is that we are too tribalistic and religion blinds people to facts staring at them at the face. It makes people so blind that they don't even recognise trouble when it is sitting on their laps! What should be the way forward is to have more awareness created about the diseases, HIV is no longer the death sentence of the 1980s, carriers of the virus can even live more quality life than non-carriers if properly managed.

Please i need advise on solar I can buy that will carry TV, fan and deep freezer and maybe 3 bulbs...

And the cost

A fan is about 80 to 100w for the regular fans and about 30 to 70w for the rechargeable type. A TV is from 55W (if 32 inch LED) if more the wattage increases, conversely, if less it'd consume less. A deep freezer wattage ranges between 200w to 450w depending on the size, make and model of the freezer and the temperature of the items in it. The freezer draws more current if, for instance, the things inside it are not cold; and the freezer takes less current if already cold.

The favourite low energy bulb ranges from 3w to 20w. I'd assume the lamp you are using is 15w; therefore total power consumption is 45w for the bulbs.

So assuming your total load, I can say you have 300w ( deep freezer) + 100w (fan) + 45w (bulbs) = 445w

You didn't make any mention of the number of hours you plan to use it, so again, I'd assume you want to use it for six hours (between 10am to 3PM)

Energy consumed is 445w x 6 hours = 2670 watt-hours (WH)


If you are running a 24V battery system, i.e. an inverter that needs two 12V batteries to function, to calculate the theoretical number of batteries capacity required we have:

2670wh / 24v

111.25Amps dc per hour draws from the system.

Battery capacity is expressed by how many Amps for how many hours a battery will last - Amp-Hour (A.H.) capacity.


For 6 hours for a 24-volt battery, we will require 111.25 amps DC x 6 hours = 667.5AH


If you are buying 200AH batteries that will be 667.5AH / 200AH = 3.3375 or approximatively four batteries.

I see someone selling 200ah batteries 70k here. Though prices change dependent on make and quality. That means you require 70k x 4 = N280k for batteries.


Now since the calculated energy is 2670wh, you will need some solar panels to replace the 2670wh of power consumed by the devices you run.

A 300watt panel will produce in 6 hours of sunlight 300*6 = 1800wh.

But we know in reality that it will not produce 100% of its rated capacity but rather between 30 to 50% of that. Going by worst-case scenario (30%) we have 1800wh * 0.3 = 540wh

Therefore we will need 2670/540= 4.9444 which we round to the nearest figure- 5 numbers of the 300w panel.

Assuming you buy the standard Chinese clone which ranges between 52k to 60 k you will require 52k x 5 = 260k

In Summary

Battery cost = 280k

Solar panel cost = 260k


I did not add the cost of the inverter and charge controller.

I can only say the budget between 200k to 220k for both.

That makes the total cost approximately 740k.


This may be less or more depending on the quality of the product used and the person running the installation. I was only trying to give you an idea.

Experts are welcomed to weigh in on this


FYI: I did not add the cost of wires, installation of the solar panels, breakers and other accessories as that is dependent on the person(s) doing the job for you. This is just purely an approximate estimate.

specter:
I saw it. I really wish those who went short on their shares happy times. 24b plus in their pockets. That's no joke money.

I sincerely hope airbus will do a proper check on their A380max. This gives them an opportunity over Boeing.

I prefer them anyway. Boeing should go back and overhaul the entire system.

Short sellers will definitely be smiling to the bank.

I always like the way information that even if paid you may never get is disseminated for free here

They've lost more than $24b in shares since Sunday.
Grounding it may just be the quickest way to restore confidence in their products. I'm really a fan of Boeing and I hope they fix this to prevent more people from gruesome untimely death.

Don't bother yourself. I use Glo too and it's Super fast. Freemanbubble, this is 2019, speed is location based. That your almighty Airtel is what is worst in my place. Try Glo's 4G where the reception is good and thank me later.

Truer words has never been spoken.

Season of fire. I guess we have to be extra vigilant on inflammable around the house. Eg petrol, use of candles, insecticide sticks, use of iron, cooking rings, etc.

But my glo is fast

That's even sadder. I hope they all find peace at last.

What else is new?

primusmaximus:
I have attached an extract from the manual of the hybrid Inverter I think I'll get. It shows the Inverter's charge controller can be programmed to deliver a charging current of 10A to 60A to the batteries. The default current to the batteries is 30A regardless of what gets to the charge controller. The excess will be sent to the load.

Also, the 3.2hrs from my previous calculation only applies if I'm using just one 200Ah battery. If using 4 batteries then it should take abt 12-13 hrs to charge from empty.

Do you know much about Mono and Poly Solar panels? All the research I've done shows that Mono is better. I'm just wondering why Poly costs more in the market.

On the contrary monocrystalline PV panel is more costlier than the polycrystalline type. The technology between the two had so advanced that the line that divides the two are today blurry. But the only difference is that polycrystalline panels tends to perform better under higher temperature while monocrystalline tends to perform more in cooler weather. Also, if space is not an issue, a 300w monocrystalline solar panel is smaller in dimension compared to the polycrystalline.

dreamwords:
Charging deep cycle battery in 3 hours is an over Killing, deep cycle battry are not designed to charge that fast, u need to respect the rule of c10 unless u plan to b replacing ur battery every now and then

That's why the charge controller is there to do its job- regulate the amount of current that gets to the battery.

primusmaximus:
Your neighbor is really vexing lol. Do you know much about 'icellpower' and 'ipowerplus' Inverter brands? They both have Service Centers in Nigeria which I feel is a good thing

A friend once bought an inverter that looks like the type sold by iCellpower from PSCSOLARUK in Lagos and inverter had lasted for three years with no issues. However, I've heard great feedback on Felicity inverter on excellent after sales support. There is this annoying feeling that comes when you tried to resolve an issue and get only stories. So, I think it is worth buying from people who may not turn their backs on you as soon as the money hits their account.

primusmaximus:
Thanks for the clarification. I'm considering getting 12 250W solar panels for four 12V 200AH batteries (5 KVA Inverter, 48V), is this an overkill?

There is never an overkill when it comes to solar panels, the more the merrier.
It means you'd have no problem getting your batteries to float (charge full) in almost virtually any weather condition. My neighbor uses 16 nos of 300W panels for his 48V inverter system comprising of 24 nos of 2v 500ah batteries. He's still planning to add more panels.

primusmaximus:
Nice thread Terrymason. What is your opinion on Hybrid Inverters (inbuilt charge controllers), will you advise against getting them? Also, what are the advantages of having many Solar panels (20+). Thanks

Most people believe a standalone cc is more robust and does a better job compared to the hybrid. That may be a subjective belief as some hybrid are pretty good, like in things of this nature you always get what you pay for. If you pay for premium quality, you'd still get that premium performance. The benefit of having many solar panels is your batteries get to be fully charged faster, and also gets charged on cloudy days. Also, the number of batteries determines how many solar panels you'd require for sufficient charging. E.g. if you install 24 numbers of 12V 200AH batteries, there is no way the size of solar panels will not be more than 20 250W, unless of course, you have a small load that it is catering for, in that case, you do not really need to size that battery bank that large to handle it.

crownwell:
what does it mean please

It means you should start getting worried if after 15th March your package has not gotten to you. But for now you'd have to chill. It usually takes an average of 60 days to declare a package sent via post (excluding the likes of FedEx, DHL, etc) missing.

I'm only here to read comments.

Trippledots:
what do you think about fangpusun cc as against makeskyblue or powmr?

Fangpusun can handle higher current more than any of the other two and most users complain of being unable to use more than 6mm size cable on either the pv or battery terminal section of the MakeSkyBlue or Powmr CC, in Fangpusun you can easily use a 16mm cable on the cable terminating point of the CC. Fangpusun has more customization and data logging ability too. If you can afford it, go for it.

Sad story,the law should take its full course,also the passengers in the vehicle didn't handle the situation calmly,you don't overheat situations especially when dealing with an armed person

No matter the verbal confrontation, an armed officer should never open fire on an unarmed civilian. The military/paramilitary members are supposed to be "The best of men." If you cannot be the best of men which include knowing how to behave under pressure/confrontation, then the person has no business handling a gun! We shouldn't fear for our lives when we interact with members of our security agencies that gets paid via our taxes. Although I don't support jungle justice, I know of many area where the man that opened fire will be a mound of smoking flesh. The young men there did restrain themselves given the level of anger they experienced seeing a man shot dead for simply refusing to offer a 5k bribe!

Trippledots:
as for that mppt, i thoroughly researched it before buying that pwm and i felt it was an overkill for my system. i may have to buy it after all. btw, that powr model is actually a clone of the makeskyblue original fyi

That clone issue is hard to prove
There are these back and forth accusations between these two. The difference between the two is not much: by the way I have seen both and I don't really see any difference between them hardware wise apart from the software little difference. That being said, getting an MPPT won't be a waste of money.

I'm still a bit confused on the part the laptop charger plays.

Trippledots:
i have an issue with my landlord not allowing pv installation so i really cant increrase my panels as i would want,and connect the two panels in series.

Also, how is it much of a difference to your landlord if you change your panel connection configuration from parallel to series as I think you already have two panels connected in parallel? I thought the problem he has is with you adding more panels.

Trippledots:
pls house is this normal?

i have a very small setup. two 100w panels in parallel charging a 180ahr battery. i average 40w draw on the inverter but thats not the issue. My battery measured 12.9v when i got it but i haven't been able to get it up to 12.7v ever since. i added a laptop charger to the solar input just to boost the input power. laptop charger clocks in at 89w and the battery voltages rapidly rises once there is power supply. but i noticed that once the battery voltage gets to 12.6v, the voltage drops to 12.4,3 and 2. looking at the wattmeter on the wall shows the charger watts drop to less than 3w.

my concern is why is the pwm cc disconnecting the dc source at 12.6v when it is set at a float of 13.8v?

It's not normal. I really do not understand the part about adding a laptop charger to the system. You mean you added the output (in DC) of a laptop charger to the input of the CC or directly to the battery?

I think the problem may likely be the PWM CC. Try getting an inexpensive MPPT ,and connect the two panels in series. Do you ever charge with the inverter? If you do, what voltage do you get when you do.

The man should face the music. How can you kill someone over N5,000? I don't get it.
