Are they for sale? I'm interested

Oshomo12:
Ok, how do I contact you, mail or WhatsApp(I don't have the number though)?

Ijeoma660:
@mcTrinity @NiyiOmoIyunade @makavele

Thank you for all the selfless support you are providing here...

Please I am about setting up and commencing my DIY solar project. I have

i. a 3KW, 60A mppt CC
ii. 4nos PV panels whose capacity [wattage] were not stated but made by afromedia. i assume they about 250w each. I think I was wrong in my assumption as I later realised the panels were under 100w each.
iii. 1.4KVA inverter and
iv. 2x200AH deep cycle batteries

Kindly advice what size and type of cable I require between the pv panels and the CC. The distance from pv panel to CC is estimated around 12m max.

Ijeoma660:
I successfully mounted my pv panels and here are my CC readings today.

The first pix at about 7.00am and the second around 11.42am

Any useful comments will be appreciated

makavele:
Are you sure that CC is an MPPT type ?
By my calculations, it is stepping down the voltage to battery level ( and multiplying by charging amperes) to give Power..
Without upping the charging current using the extra voltage . . . Maybe I didn't check it well, will do again . . .

Not bad at all, but in the end, how did you string the panels?

By 7 A.M, I am already seeing about circa 150 Watts, though on a larger array !!

@makavele
Please what is the size of your array?

Ijeoma660:
I parallel-ed all four panels.

makavele:
Presently sitting @ 1.8 kWp and counting . . . *small though*

makavele:
I thought you had an MPPT CC; why did you have to parallel all four panels
My guess was good then!

chris81964:
If you did that and are getting more than 30 V from your PV. They are bigger than 100 Watts. Your voltage will be in the high teens after the controller kicks in on 100 watt panels.
Do you have the manual? You might want to connect them in series, thinner cables, longer distances and better efficiency. Good luck welcome to our world. The most I saw out of 2600 watts today was a little under 1500 watts. So if you are seeing over 300, you might really have 150 to 200 watt panels.

chris81964:
You have more 400 watts in PV if you are in Lagos. It looks good. Is that the 60 amp controller made by Voltronic? works fin on AGM batteries

sinistrian:
@chris81964 @NiyiOmoIyunade and @makavele Is it strange to get 20A max from a 2x2 arrangement of 300W panels? That's the highest current i've seen today @ around 12:30pm and my batteries were about 57%, even after washing the dust off the panels daily. The panels are ground mounted (i didn't have any other option, landlord issues) and the Charge controller is a Fangpusun MPPT 100|50.

makavele:
Strange !!!
You should be between 25-30 A during this hazy period

sinistrian:
Ehen. Because with a max possible input of 17.66A from my array (each panel has 8.83A I_mp) I am sure the MPPT controller is already doing 'something' to get me to 20A output, just not enough. What could be the limiting factor(s)?

makavele:
Your panels V_mp shuld be at 33. something. So in an ideal condition, with your 2 x 2 config
your input to the controller would be about: 67V18A (rough calculation)

Limiting factor 1: Battery bank . . . If your battery bank is a 48V one, there is little or no voltage headroom to convert excess voltage to ampere. If it is a 24V bank, should be sufficient enough to convert excess voltage to amperes; if a 12V bank, very cool.

Limiting factor 2: Faulty charge controller . . . that is limiting your output for whatever reason (incorrect battery profile selected, etc)
or losses due to bad wiring system.

makavele:
Take a snapshot of your installation and post here; so we can work with facts and not guesswork

Thanks

Good day everyone.

Please I need your intervention concerning a purchase from JUO. I have transacted with him few times successfully until recently that he stopped picking my calls while we still have a transaction not concluded yet to my detriment.

I bought 2 units (12v 190ah) of used batteries from him barely 4 months @ 80k each for a client on 1 Sept, 2017, I planned buying new but he was able to convince me that these batteries are better than the new ones I wanted to buy, so I opt in for his option and he promise me a guarantee of 6 months if client discharge 50% only. I paid him and he supplied the batteries to me, few days after installation we were chatting and he asked if he has a solar system installed and I said NO... he said that's bad o, he barely gives people warranty with no solar and I told him this client lives in an estate with about 20-24hours power supply daily, he's only trying to make sure he covers up his 24hours power supply always, that's why he's getting it and there won't be a problem concerning charging of the battery but I will persuade him to do solar, that's all.

I can't force money out of the client's pocket likewise you didn't base your warranty on a condition before you sold it to me, it was after you sold it you were talking that condition... and that's not a goal to me, even batteries perform well without a solar system, so not a solid criteria.

About 2 weeks ago, the client called me that some liquid came out of the battery terminals the previous night and he's been observing for about 4 days that battery barely last 30minutes from the previous 9 hours it's used to. I went there 2 Sundays ago to inspect the batteries and the terminals are dried, i didn't see any vivid traces of water and I met battery fully charged, so i disconnected the grid supply to see how long the battery will last and behold, less than 20 minutes it started alarming and 3 minutes after, inverter went off.

I informed JUO and he said he can't be responsible for total refund (even tho that's not conditionally stated in his warranty, what he told me then was he will replace if battery is default) and now he said he can only give a discount on another purchase.

Client said he's never going to buy used again... Poor experience for me as well.

His discount was client is to pay #130,000 for 2 brand new Mercury 12v batteries. Client insisted on #100k because he can't lose such money within that short period. And I had to come in just to protect my integrity, I agreed to pay #30k from my wallet.

Client called me yesterday that he's ready for the purchase. And I informed JUO and since then he has refused to answer my calls, nor reply my text and whatsapp.

So I am begging everyone to implore him to fix this transaction even though I will never have to deal with him ever again. And I am not "mr. dangote" to bear a burden of #100k.

We transact with each other on here most times based on trust, we never meet each other and I do believe everyone has a name to protect, so kindly implore him to do the right thing as agreed... This JUO is a man I have input my words for on this forum for a good services & delivery rendered, so I never expect him to show this ugly side of his to me.

Kindly help everyone pls!
