My grassroot teacher, anxiously waiting!

GeorgeD1:
all,
my solar water heater is finally up and running.
pictures to follow soon.

kool & totally efficient

na wa ooo

master will always be master.

Nigerians are always better where they put their minds. we are learning from you sir.

I wish there is no recession.

Thank you for the words of encouragement. We have a customer running three charge controllers on 8.5 kw in panels. Some day I will have that much on my roof.
Recessions come and recessions go. Nigerians are the most talented group of people in the world. Naija no dey carry last

Yes its a gradual process...

Dreamflyin no dey hear.
SOme1 has asked him his cable size and distance..he simply said its god blah blah blah.
NOw he goes off to acquire an mppt cc without eliminating all likely causes.

Dont think we shud bother trying to help u till u start showing some seriousness.
1. how many strings of panels do u have.
2. are u using a combiner box.
3. what size of cable are u using in mm or awg.
4. Whats the distance from panels to cc
5.whats the distance btw cc and batt bank.and what is ur cable size.
6. what is the make of ur panels.specifications..are they all the same make..hope u didnt mix poly n mono. 80w. 150w. 250w on same string etc

I don't have a caliper yet, to check the cable size, but it should be 5-6mm. I tired uploading pic.
Combiner box? No.
Distance from PV to CC would be around 15 - 20feet.
CC to battery should be 3feet Max.
All pv are poly.
8 250w panels.

..but please, I thought MPPTs does a better job. If PWMs were giving 20a at peak, should MPPTs also give same?

nice, little Paradise shame on power holdings & discos

i commend your bold choice going 4 mppt.
don't be discouraged, lucky u it has offered u a real opportunity to gain experience you can't buy off d shelves.

by the way it is too early to determine mppt is harvesting less using 2 to 3hrs. in my view.
1.check if ur cables is rated > 6mm (beta if is 10-16mm awg), if OK then

2. disconnect all ur PV config. if ur running 3x2, load & test each set independently, u will surely notice a set probably from ur last setup down d line drawing you down.

3. consider reviewing the type of ur grounding style.

however, try and draw ur installation so dat masters and gurus can attended to u quickly.

my regards

I wish I could draw the connection. An installer did the job for me.
Par the duration I assessed the Cc, I left it for a whole day. It did Max 22amps, same as my two PWMs.

Cable sizing spotted in your pics really looks RIDICULOUS ! Contact me for 10mm×2 armoured copper cable"with grounding/earth strands" seen in pics below @N1400 per yard. Utilize 16-25mm cable upwards from mppt to batt bank...2×2 panel config works BT 3×3 works best esp on I Tracer ...

YOU still didnt state how the panels are connected, how many strings, if you are using a combiner box etc.
5 or 6mm is too small for 2kw panels, if you dont understand the connections/what the installer did, your best option is to get a good installer or some1 who is knowledgeable about the whole thing to guide you.

you are providing half n half information , maybe cos you dont know, or dont understand the reason why we are asking for all those info, n its a bit frustrating...
since u said u hv 8 pnels, its likely ur installer used 4 strings of 2 panels or 2 strings of 4 panels ]not so good for itracer].
state ur location, maybe some1 here who has knowledge can volunteer to help check ur system out

nb: most cable size is written on the body of the cable!, look carefully/closer

Obimind1:

Something must certainly be wrong with ur set up. In as much as pwm is not effective as mppt, its still not doing bad on a small set up. Using my self as an example, 4 of my 150watts panel(600watts) are connected to my 30amp charge controller, and the minimum I get on a rainy or cloudy day is 35amps. This days that we no more experience rain in the middle belt area of nigeria, I harvest up to 60 amps. I formally had the same complaints u're giving currently but luckily I ran into a well experienced installer who discovered that my wires were seriously undersized. After installing the right wires I recorded a great improvement in my harvest. Contact an installer to have a critical look at ur set up and I believe u will be fine.

this is not scientifically possible in this century, maybe in the next century it will be.
getting 60amps from a 30amp cc, from a 600watt panel?
pls crosscheck and verify what you wrote

In addition, the 30A cc should clip the current at 30A. You shouldn't see 31A sef...

I guess u didn't get me right. The 60amps u saw me talk abt is my harvest for a whole day.

The current drawn depends on the state of charge. If a battery is almost full, the current reduces so when comparing make sure to state the voltage of the batteries.

Dreamflyin:
Please house, I need help. I'm now as confused as hell.
Since my two 40/40amps PWMs were harvesting 22amps at peak from the 2kw PC array, I thought that installing a Mppt will help issues.
So off to the electrical mart I went for one.
I got offered a Xantrex (Schneider), a ETracer and Itracer (both EP solar).

On installing the ETracer there was no improvement in harvest, rather a decline in harvest. It did 20amps peak.
So back I took it to the dealer and got a refund.
The Xantrex, based on the poor performance of the EP, I insisted in having it test runned on the 2kw panel setup there. Man! it did 18amps while the PWM that was there harvested 32amps off that same PC array.

Now am confused.
I thought Mppt is far better than a PWM?
What's wrong?
It's a 24v system.

Obimind1:

You should have said 60Ah then. Current (A or amps) is an instantenoeus quantity and is very different from ampere-hour, AH which is a function of current and time. Solar harvest is stated in AH or WH.

Thanks for the correction. I do appreciate.

Gurus in the house.
How is this Agisson batteries and do we have 6V option?

Mainly 2v. I haven't seen any 6v options

It's OK in terms of performance

hello gurus, I already have a setup which comprises of a 1.5kva inverter and 2 12v, 200amps batteries. I want to add a solar system to it. I got an advice that 2 200w mono panels and a 60amp mppt cc will be enough to charge the system and power 2 led tvs, 2 decoders, 1 sound system, 2 ceiling fans and about 5 nergy saving bulbs, although I dont put on everything at the same time. My 1st question, is this setup ok or does anything need to be upgraded as per the solar installation, and what is the price range of the panels and the charge controller in this "buhari period". Thanks.

welcome to solar world. i can recommend the great kiekie1 am sure you'll get best deal.
am sure he will also insure you against buhari prices 4 atleast a week.

l also have great faith in the ability of gurus in the house to resolve ur fears

welcome to this great thread, I will recommend Dmerciful for you, he will give you great info and not just because he want to try and sell something to you in the end or convince you that what you bought is inferior/inadequate so you can buy his own

@Dmerciful,is a generous scholar,when it comes to solar setup.I want to assure you that you would be glad if he begins to posit solar stuff for you here.I strongly recommend him this-wise.Mind you,he doesnt sell any solar materials,just an enthusiat.God bless the day,i got to know him.I can authoritatively say my solar life has not remained the same since i got to know him.Godbless you man.RE rules,green for life.One love all.

Your setup is very okay. You can add more panels+batteries in future if you intend to use fridge/freezer + go off-grid. I recommend kikie1 for purchases, Dmerciful for advice. Congrats.

You are right Dmerciful is great guy, selfless and generous. Some here are trying but are usually seller so their advise dey dey some how especially if no be from them you buy

@ codemaster2much, @ monlo, @ mank1234, @ dicksonadams , thanks very much for ur kind words...seeing people go renewable and helping in any way I can gives me joy.

@ foonshur
In setting up ur system, there are some units that are not modular per se and as such needs proper planning from the onset. You battery bank cannot easily be increased as you become buoyant cos of the limitations of mixing old and new batteries so better to buy like 4batteries of 200AH one time. Also the 60A mppt is OK...as it gives room for future expansion. You can buy fangpunsun flexmax or epsolar itracer...these are not that expensive but quite good. Use at least 8mm cables to run ur panels so you don't have to replace cables when d need to expand arise. For ur 12v,200AH * 2 batteries, their kWh is 4.8kwh(24*200ah) and as such requires a solar arrangement that can deliver 4.8kw per day. A solar setup that can give 4.8kw must in reality be 4.8kw/0.6 =8kw as you can only get 60% due to changing sun angle on d horizon from sunrise to sunset and also as it moves from Capricorn to Cancer(a bit intellectual). So you need about 8000/(200*=5 panels of 200w(8hours of sun projected) but to cater for cloud covers periodically I'll advice 6panels and mind you your batteries will not be drained everyday. Cheers

thanks guys I really appreciate your prompt and honest responses.
@ DMerciful
6 panels? damn! I'm not goin to depend solely on the sun to charge my batteries as I have a perkins generator and also still connected to the national grid(although I get like 5hours of supply in 2 days) so the point of having a solar setup is to save on fuel. like I said, jst want to power the basic appliances as the refrigerator and ac will be considered much later.

You cannot be talking generator if you're talking renewable energy . 6 panels is not much or that expensive .

@ DMerciful bros, I cannot become a champion 1 time, I have to stepup, to stepup , to stepup I have reduced my generator running hours to about six hours a day, a great feat if u ask me. then abeg how much will the 6panels be?

We have sellers like kiekie1 or email me for more options
