Dunka, that 145Vp is too close to 150Vp!
This na just wet season, what happens when dry season reach?
Your cc will be damaged if that voltage level is breached!

skalamanga,

going back to my earlier example above, it even gets better when you think of solar as a means of continuos power supply and not just like a generator which you start and stop every now and then.
let's say you have a solar power system which supplies you steady power during the day and a back-up system that supplies you power all through the night, the difference between solar and generators becomes just staggering!
if i were to run my generator on a 24hr (or minimum of 12hrs) basis like i was using an inverter, here's what we'll be talking about:

let's rewind:
30ltrs in 1 wk of roughly 3 hrs use daily becomes: 40 litres in 12hrs or 80litrs in 24hrs.
we will stick with the 12hrs minimum use option.
40ltr/day becomes 1,200 litres/month
at the present pump price of 65naira/ltr, this becomes: 1,200*65=  78,000 naira per month.
in a year that amounts to: 78000*12 =  936,000 naira per year
assuming pump price remains the same (which will be virtually impossible), in 25yrs, this becomes:

936,000*25 =  23,400,000 naira.

here it is! if you were to run a 5ka petrol generator for at least 12hrs everyday, you'll end up spending about 23.4 million naira in 25yrs at the present pump price but as we all know, the pump price can never remain the same over that long a period.
now the big one: if you were to run that same generator for 24hrs everyday (which you can achieve with a solar power system) you will end up spending 2 times that amount in 25yrs:

46,800,000 naira!

for less than one-tenth of this amount, you can install a solar power system that gives you trouble free operation for over 25yrs!

now, who still says solar is expensive?

This is definitely fake. It's amazing that you deliberately decided to become a victim of fake tinted glass permit with all the information & sensitization on this forum regarding the process for tinted glass permit. Part of the reason share experiences is to educate other intending users of such service and equip them with firsthand information so they can be better guided when applying for such services.

For sure, police officers at the various check points will happily prey & feed on you. No two ways about it. By the time you call the number given to you by those who extorted you, the number will be unavailable.

Giving the porous nature of permit issuance and the multiplication of signatures by the police and in order to avoid the proliferation of signatures on the tinted glass permit the NPF high command decided to centralize the process as well as the signature (emphasis mine). The permit is signed by the CP FEDOPS for the IGP & no other officer is allowed to co-sign it.

In your best interest, start a new process of obtaining the tint permit with the right channel already detailed herein & follow through to the end.

Just my thought.

DUNKA:
with this your username I trust you will not accept this crap. By the time you dey for road I can assure you the number will be busy and by then grammar will start

My brother to not be deceived as of today this is a fake behind the door permit which will cause you only trouble. Please see how a genuine permit with Biometric duly captured is meant to look at.

There is only 1top officer designated to sign and even the police in the field know that.

Do not be deceived but sorry your money don enter voice mail

DrWise:
I went back today and confronted the officer that what he gave me is fake without BIOMETRICS, he took me to the Assistant Commissioner who explained that the capture and biometric stuff was bringing various issues and the IGP has directed that this be issued and a communication would be sent before end of next week. He gave me his number if I am disturbed to call him.

The attached is what my 10k and 2k at the gate bought.

freshcvvs:
Please help me with this, if i need to leave a shop i rented few months ago and another tenant in the same property wants to rent the shop, do i get the commission and agreement fees that i paid back + the remaining months on my rent? will the new tenant pay a fresh agreement/commission fee?

DrWise:
I went to Force H/O here in Lagos and I was asked to pay 10k. I paid and asked for capturing and they said i dont need to capture, i should come back same day to get it. How genuine is this?

Teeboy06:
pls what's the procedure and how much you eventually paid ?

guys,
this post was made by my humble self on the 4th of august 2010 - more than six years to the day (ref. page 2 of this thread). looking back now, I can't help feeling a particular sense of satisfaction that I made the right choice to go solar

Barezzi:
No issues at all kiekie1. It's still Bright and spotless as if I bought it this morning.

Yes Dunka.

Battleaxe, I prefer the hybrid inverter to modular setups.

I currently own the Magnum MS4348PE, FM60 charge controller, PV array of about 3500w, 400Ah 48Vdc battery bank, dc disconnect box, surge protectors etc. I've been using this for more than 4 years i think...

I'm currently dissatisfied with it cos it's dumb. I've been racking my head on how to implement an intelligent energy management system with it, but no luck.

I want a setup that can intelligently look at my PV production, Battery capacity, PHCN, time of day and smartly decide the mix to power my loads.
A smart hybrid inverter can comfortably do this...
Hey, my setup listed above is up for sale, interested buyers are welcome

@ Gurus in the house.

Well done! Every time I think I've got this figured out, then I hear some new insights from you learned folks.

I have a couple of questions, which hopefully the house is able to help with:

1. What is the best connection for a 3kWp solar panel installation, with 6 nos. 12V, 200Ah gel batteries and a 4/5kVA, 48V Hybrid inverter? What brands would you suggest?

2. Is there a preference for flooded lead acid over say gel or AGM batteries, in a solar, partial off-grid system?

3. Re Dunka's comment on the Axpert inverters and their undercharging of flooded batteries. Is this problem just for flooded cell batteries or also for AGM and gel batteries?

4. From searches, is a de-sulphator really required for small battery setups such as the above?

Thanks for your kind responses.

Barezzi:
Chei Dunka, this is mouth watering. Congratulations bro, and welcome to the club!

I am in need of a Goodwe GW5048D-ES hybrid inverter. Any dealer/seller please respond, thanks.

iLoveTheSun:
@DUNKA

Thanks for sharing the link. I hope many will find it useful to learn how to wire properly.

Without knowing the length of the ground cable, I'd go for safe harbor. Surge protection for DC photovoltaic is more demanding. I'd recommend to install the DC SPD outside of the building envelope and leave the grounding cable outside the building. And I would run the cable the shortest way (low resistance).

By the way, the last indoor pictures show indoor wiring and battery setup. Is this the bespoken installation?

JUO:
you and Abu want make we thief?

Various Solar Accessories

Total Price:

I am a complete novice in this how I was able to set this up was what I gleaned from here then gathered all the accessories over a period of about 2years.

To this end let me hail all that have contributed to this thread but most especially GeorgeD1 who invaluable early contributions really pushed me down this line. Though it seems he no longer active on the forum and to Chris81964 whose background advise has been invaluable.

I also give a shout out to all the suppliers of my solar items namely CoOgumo,Richmon,Gennextec, and the one and only Chief Marketer Kiekie I will say that I have never met anyone of them in person and we have transacted seamlessly as payment is made and items sent no long story. Anyone can deal without fear.

Though a novice let me give a little advise if it can help anyone. Start small as you will be discouraged if you try to buy everthing at once.

For the inverter please go for the high end products Magnum, Scheinder,outback,victron,SMA, as all the ogas in the house use them so that should tell you something.

Do not buy the cheap Chinese,Indian and Korean inverters. If constrained by funds go for Prag or Voltron.
For the charge controller also go high end if possible with Outback,magnum midnite solar, morningstar etc. Being the top brands.

For Batteries I prefer flooded due to its resilience and particularly for the ones I am using the electrolyte indicator is a God send as you can easily see when the cells need topping off (newbies take note) . Good value for money.

A word if caution if you are using flooded batteries u should note that the popular Axpert inverter is limited to 58.4 charge which will undercharge flooded batteries and will kill them. It also cannot equalize flooded batteries you will need a good quality CC to perform that for flooded batteries. I know because that was my 1st inverter before I now went for the Outback. Also note some branded inverters advertised I see here are Axperts so you have to know the right questions to ask. That been said it served its purpose for me and now will dispose it or keep it as my back up inverter for when there is any issue with the Outback.

I strongly recommend that you protect your system from lightening strikes by using surge protectors on both the A. C and D. C sides of your system. Thank me later

Please do not ask me any technical issue as I just got the items and paid for installation.

Also do not ask for price as with the fluctuating dollar rate prices are totally crazy now so whatever I tell you will not be correct as of today. If you do not believe me agree for an order with Kiekie and you do not transfer immediately by the time you come back after a week you go know say khaki no be leather.

Solar is the only way to go as in the long run it is cheaper than the unreliable grid which makes running g generators very expensive

As a whole get the correct information before you start. My last word of advise change all yr light bulbs to low wattage LED bulbs. You will thank me later.

Installer are still tidying up the install. Will post the internal set up later.

chris81964:
Awesome job brother Dunka. I will be stopping by when I come to Plateau State. I expect a bowl of kunu. The person that did your panels did an awesome job. Those tubular batteries can get a real good charge. Change the charge current on your outback to be 13% of your total battery bank.
Your advice is invaluable and on the money.

iLoveTheSun:
@DUNKA

Nice setup!

And a very good choice of components (-> Solarworld + Outback + Flooded batteries + Surge arrestor + Desulphator). I guess, you will be happy for a long time (and make some folks jealous in the house )
Either you were professionally consulted or you knew what you wanted. (And this demands some $$$)

Yes, I do agree. Solar is the best way to go!
Keep in mind. Good quality solar modules will last 25 years. Low quality modules can "break"/"burn" within five years. The difficulty is you only know when sh:t happens or it doesn't. But then it is too late, right?!

God bless...
