you're welcome to the solar league - where the possibilities are endless.

what is the brand name of your mppt solar charger?

looks like i'm seeing this for the first time.[/quote]Oga George, I no get money yet for brand o.
Na China I dey befriend so.
On a serious note, the model number is emppt3024z.
It has a serial port for remote monitoring and data downloading although I am still speaking with my supplier to get the needed softwares.

jayboskie7: bodejohn
How much is the cost for this charger.

About $300 excluding shipping and bank charges.

As promised, the pictures of my solar charge controller and setup.
I was only able to harvest 12Ah on the first day because it was past midday before i installed it.
I already had like 12Ah charge stored in the batteries before 11am today.

CNN80: The inverter voltage is 24. I thought, if I got 3 batteries, of connecting the first 2 in parallel and then connecting that setup in series with the last battery (giving me 24V) but I've been told that is a bad idea.
I wish I had known that the inverter was 24V before I agreed to buy it.

Do not blame yourself for picking a 24V inverter, i think it is even better and more stable than 12V, although i stand to be corrected.
Your setup will only permit you to use batteries that are in pairs so long they are rated at 12V, there are some batteries that are not rated at 12v.
So i will advise that you go for 2pcs of 12v 200Ah batteries, remember also that the bigger the batteries in terms of the Ah capacity, the longer it will take your inverter to charge the batteries to their full capacity.

One of the reasons why Europeans are not legally getting married.
The cost of their divorce can settle boko boys forever!

CNN80: Hello, please I need advice. I want to buy a 1.5 KVA inverter and I have the option of getting two 12V, 200Ah batteries or three 12V, 160Ah batteries. Which one do you suggest I buy? Thanks

@ CNN80, the first thing that will determine the number of batteries that will be needed in your setup is the operating input DC voltage of your inverter.
If the input voltage of your inverter is 12V, you can use any number of batteries so long it is connected in parallel. But if the input voltage is 24V, you can only use batteries in pairs, that is, you can only use 2 or 4 or 6 etc, but if the input is 48v, the batteries will be in multiples of 4, that is, 4 or 8 or 12 etc.

Since your inverter is 1.5KVA, assuming the input voltage is 12v, with 2pcs of 200ah batteries you will have a storage capacity of 4800watts but with 3pcs of 160ah, you will have a totally storage capacity of 5760watts. But if the input of your inverter is 24v, you will have to settle for 2pcs of 200ah or better still get 4pcs of 160ah.

[quote author=George_D]bodejohn,
yes, what we have here with solar is a ppp (personal power project)

sorry about your power outage. it is at a time like this that the usefulness
of solar as an inexhaustible source of energy becomes very evident.

will call you later on today to have a chat.

cheers![/quote]Oga George and all,
I finally received my charge controller from DHL, it came with a serial port to connect to a PC, although my supplier initially told me he was going to send one without pc communication. I will upload the pictures of the setup tomorrow after I have reduced the size.

Oga Geroge, I don join the league of independent power producers like play like play o.

This statement credited to the respected preacher is certainly out of place. More than ever, I can see that the biggest problem in Nigeria is certainly not corruption or tribalism but religion.

Oga George, many thanks for the call. I am very humbled.
I returned to my abode to discover that there's been power cut for 5days.
My batteries were flat as I left the security lights on the inverter while we were away. I thought there wouldn't be any power in in he evening if I didn't act fast.
So I had to quickly connect the panels together and wire it to my batteries monitoring to turn it off as the sun went down because I still await the delivery of my mppt controller by DHL.
I must say that I wish I had more money on me, I would have headed back to Lagos to buy more panels because the thing dey sweet my belle.
With your help and some personal research I have solution to what even the federal government could not fix.

[quote author=George_D]no, bodejohn, you can't just connect all 4 panels in series like that.

depending on the type of mppt charge controller you have, there is a maximum open circuit
voltage each one can handle. thown all the panels you got at it will fry out your charge
controller. besides thee is a also an optimum operating voltage the charge controller
needs to down-convert into useful current to charge your batteries.[/quote]My charge controller has a solar input voltage scope of less or equal to 70v and maximum power point voltage tracking scope of 24 to 70v if 24v battery bank is selected and rated for 30A. Might be save on the 4 panels. What do you think?

I wonder if there are still comprehension passages and question in our schools.
I will break it down for you folks, the man already suffered a stroke, he would have been burnt in the fire.
He was saved from the fire by his wife.
It is still an act of bravery for the wife to risk her life to save an already bedridden man.

[quote author=George_D]ok bodejohn,
i thought it was a 36v system you had. since it is a 24v system, you can make it 2 panels in series.

in the long run however, if you want to make full use of your mppt charge controller, you should
connect at least 3 panels in series else you won't be able to reap the extra benefits of mppt
and the charge controller would work like a normal non-mppt controller.[/quote]Oga George, sorry for the double post on the forum and on the mails. I just want to document the learning on the forum for others to learn.
Since the voltage from the 2 panels might not be enough, maybe I should connect all 4 panels in series.
This should give me a minimum of 50v which should be good for my mppt charger. What do you think?

[quote author=George_D]bodejohn,
from your specs, what you have are essentially 12v solar panels - never mind the nominal 17.82v stamped on them.

therefore you will need more than 2 pieces if you want to effectively charge your 36v system.

in effect you'll need to connect a minimum of 3pcs of your 100w panels in series to make up 36v to charge your
system. that leaves only one panel remaining which may just be lying about unused unless you want to add extra
2 pcs in series and connect them in parallel to the first set.

hope this helps?[/quote]Oga George, my battery bank is 24v.
So I plan to make 2 panels in series to get 35v and connect the 2 series sting in parallel which should give me a 35v/11A system to charge my 24v battery bank through an mppt charger.

MAYOWAAK: I am waiting for Reuben Abati's response,I know he would in reply give it to Tinubu ,The O'sanle of Iragbiji more that what he bargained for.

Abati will be too civil, the response will be by the attack dog himself, Okupe.

[quote author=George_D]bodejohn,
you shouldn't have settled for the lesser wattage panels. overtime you will realise that the bigger panels give you more
value for your money.

what is the specs, i.e vmp, vmax, voc, isc, ioc, etc?

i need those details to be better able to give you an informed opinion on installation.[/quote]I tried the number you provided on the forum yesterday afternoon but I couldn't reach you before I made the purchase.
I had already made up my mind to buy the panels and didn't want to take the money back to my base.
The 230watts I found at vitus' was quite huge, I wouldn't have been able to transport it to my base without the risk of breaking them.

See below the parameters on the panel, there are 40cells on each of the panels.

Rated maximum power: 100watts
Maximum system voltage: 715volts
Rated voltage: 17.82v
Rated current: 5.62A
Open circuit voltage: 21.6v
Short circuit current: 6.35A

Yeah....his wish will become accomplished when the cost of petrol becomes unaffordable. We will either go back to the dark days of lighting with red oil lamps or the very fortunate ones will go solar.

The foremost problem we have in Nigeria is not corruption but Religion closely followed by Tribalism which are both an enabler for the massive corruption that we daily see in our society.

I am less concerned about the other personal issues that the former pastor has with the RCCG, but I have come to notice that pastors who are not willing to provide their "holy podium" for other pastors jump at the opportunity to offer same to corrupt politicians and the congregation in other to say that the president or the governor worship in their church are also blinded by religion to believe that the politicians mean well.

Was Akingbola not a pastor in RCCG? What was the church's reaction to the monumental fraud that he committed?
Are the other churches any better? But we are daily blinded by our religious sentiments to the detriment of our collective good.

I see religion as a self destruct button that might blow away our country.

[quote author=George_D]hello bodejohn,
its so nice to know you been reading all the posts here.

to your question, most standard 200w panels available in the market today have vmp greater than 30v.
therefore if you're using a 24v system you can safely connect both panels in parallel and your battery
bank will be well charged. however, if you have an mppt solar charge controller, it is best to connect
the panels in series (not more than 2 in series pls) as this will help boost output.

finally, please go for original sharp solar panels or suntech - if sharp is not available.[/quote]Oga George, I had to change my plans when I saw the size of the 250watt panels.
I would need a truck or a bus at the minimum to transport it, unfortunately I went in a small car.
I had to buy 4 pieces of 100watt panels.

Now to my question, I plan to connect two panels each in series and then connect the strings in parallel to get a 36V/11A system, what do you think about this setup?

fikfik: Hi George, I plan on getting a 5KVA Cyberpower inverter (with 12 batteries) and 10KVA Prag Stabilizer for my house. Some of my equipment, TV, computer, network equipment, desktop already have individual UPSs. Will I retire these from the system once I deploy the inverter? or will the UPS still be needed maybe for the sensitive equipment since the inverter may not switch fast enough? what do you think?. Thanks.

Depending on the inverter you get, there are some inverters with UPS functions.
You will not even know when it switches between one source of power and another.
I suppose a 5KVA cyberpower inverter should have the UPS feature, so you will most likely have to return your smaller ups to the store.

But on a lighter note, bros, 5kva cyberpower inverter, 12 batteries and 10kva prag stabilizer, you be big man o.
I beg no forget me for your kingdom o.

@OP
I once saw a man unrinating by the roadside in Europe, Czech Republic to be precise.
While I am not saying the shameless act of that man is justified, we need to really stop all this oyinbo mentality.
They are humans too and they also falter in little things.

Do you have a neatly used ipad 2 3g with 16 or 32g capacity?

The galaxy s advance is a good phone, I have owned one since september. Unfortunately I am not quite sure you will find it in Lagos.

Hi, is the ipad 2 with 3g?
What is your best offer for it?

Bad....worse....worst....torres!!!

I suppose Akingbola and Cecilia Ibru also once knelt before the Almighty God before squandering the life savings of their fellow Nigerians and church members entrusted in their different banks for save keeping. Kneeling of prostrating has very little to with uprightness.
I will rather prefer a pagan who fights corruption and illegality at the elm of affairs than all these attention seeking bigots.

Sexynick: Guys,pls help with the guide on how to connet inverter to car ba3 to produce alternative power.

Your question is not quite clear to me, but I will try to answer anyway.
I presume you already have the inverter, if not, please calculate you load requirement before you purchase one.
Also, it might not be a good idea to use car battery for your inverter, there are special batteries used for inverters called deep cycle batteries.
Depending on the rated dc voltage of your inverter, the way your batteries will be connected will be a lot different.
I will advise that you also go to the beginning of the thread to read more.

jayboskie7: Sir,please i dont understand this thing.kindly break it down for me. i am really a novice in this aspect of solar.just tryin to make life comfortable for me when PHCN cease their light.Kindly explain to me what i needed to buy with 3kva modified sine wave inverter that will able to powered on my electronics and other home accessories.

Thanks

The calculator helps you to avoid long and boring calculations, but since it is not clear to you I will try and give you some explanation.
Each electrical equipment has it's rated power in watts and will consume that amount anytime it is switched on irrespective of whether it is on gen, inverter or phcn.
For example, a filament bulb will take say 40watts. If you need this bulb on for 5hrs that will be 40 X 5 = 200watts. In the case that you need like 4 of such bulbs on for same number of time or more, you will have to work out what the total power required for each bulb and add all together at the end.
Same way you will calculate for all electrically powered equipment that you will need to put on when you run on the inverter. It is important that you have a good idea what you total load is before you purchase the inverter, battery and solar panels.
You will find better explanation in the thread if you read from page 1.

While the OP did a good job in analysising what the fuel subsidy funds should have been, I will like to say that the total 881billion appropriated for fuel subsidy in the 2012 budget is not only meant for PMS but also Kerosene that gulps almost same amount as petrol. Before I get nailed to the cross, I also need to point out that my observation is not a cover up for the massive looting of the country's resources by past and present leaders.
The nation is under claws of charlatans who have no regards for the wellbeing of the common man on the street.
I have a feeling that the last days of this year and the first weeks of the new will most likely be like the last one, I don already stock up some fuel, atleast, the wahala go don settle before I finish it.

ignis: Does bad government encourage kidnap of an innocent woman?
Nigeria commit all sorts of crimes and attrocities and blame it on the government.
Lets be the change we want to see.

Yes sir! A bad government encourages violent crimes.
And by saying government, i mean the three tiers of it not blaming anyone more than the other. The government has failed to prosecute those arrested for crimes to a logical conclusion thereby encouraging others to venture into it.
Justice done on time and appropriately is the only potent solution to crimes.

The words of the minister made me laugh, I hope he was not expecting any Nigerian to believe him. His anybody would rather mean anybody in the presidency.

jayboskie7: Oga George
Thanks for the other time .sir i really want an explaination from you.i have been planning to go for 3kva modified sine wave inverter.Please how many batteries do i need to buy that will be okay for this inverter in order to power my washing machine,pumping machine,television and refrigerator.Then am also considering going for wind turbine but i dont know the watts i needed to buy that go along with this solar inverter.

Hoping to read from you soonest.

Thanks
,

Let me jump to answer you.
You can use this calculator in the link below to determine the load you will require
www.freesunpower.com/system_sizing.php
I also think a pure sinewave inverter will do you more good since you will be connecting your electronics to it.

Oga George, many thanks for your response.
I already called vitus with the number you supplied.
I am thinking of using suntech panels and i also plan to use a mppt charge controller too.
Do you know any reliable brand of mppt charge controller (with the meter display ) that i can get from vitus?
