Oga calm down. Alaba boys don run you street.

This is a PWM branded with MPPT sticker. If you are still up the test and you are in Lagos, I can give you a Powmr MPPT controller for you to re-do your tests, then you come here and publish your results.

Game?

i will appreciate if you can give me the powmr mppt to confirm if this mppt is okay...like i said am using one 200w panel for now and am getting 2.6A from the mppt..when the panel is giving 6A via multimeter and my pwd is giving 6A too but i dont know my mppt is giving lower ampere in of more AMPERE

oga i no be jjc when is come to alaba... I brought the mPpt for tasha energy they are very big company in Alaba, abuja. port harcout....you can google them and visit there site...i did not buy for alaba boiz ....the controller is mppt..and i brought it directly from company at 55k...i have pwd too so i know what am saying....just test your mppt with one panel and tell me the reading

Penuelseun:
I don't think what you have there is an mppt controller, that is pwm

Oga it is mppt..it is 30A mppt
Tasha energy
MPPT SOLAR CHARGE CONTROLLER

Penuelseun:
mppt is not useless, it just works better when the input voltage is 2x, 3x or 4x more than the output voltage. Kindly share a picture of the spec sticker of your charge controller

It is a 30A controller
75voltage max.

Pls how do I get atleast 20A from this mppt controller... I will appreciate if you can put me through cos that is the reason why I get this controller

So far so good my ampere reading of the 3 panels from my Felicity Mppt has never exceed 11amps . While my PWM gets so close to 18amps . So like I said it’s the settings that matters.

You have answered my question..it really means mppt controller is useless for 12v set up...cos how can you be getting 11amp on mppt and 18amp on pwd....the purpose of mppt is to convert excess voltage to ampere...if you are getting 18amp on pwd, I expect you to get 22amp from mppt.... There is something wrong will all this mppt...it is just a waste of money..I regret wasting my money on mppt... I will need to get a bigger 60A pwd controller cos I intend to get 2more panel

BigDickProblems:
I see you got the Cworth battery that Dam5real (here on Nairaland) or so did a load capacity test on, cos I watched it today; that’s a good one especially the way he made it easy to understand.

Firstly, I will advice you get at least 4 pieces of that panel. Yes because when you connect them in parallel (parallel means you want to increase the currents by adding more panels while you keep the voltages from the panels constant), you are getting a max of around 40Amps (going by the panel rating of 9.89Amp). 40amps is 0.4C of the 100Ah battery which is ok. But you can add one more to it to charge your battery faster. It also means that your charge controller should exceed 40amps (so get a 60amps, especially for room for upgrade).

Now, your Charge controller also needs some settings. Firstly, you need to select the Lithium battery type (some controller will give it a label of “Lib” or “3-5S” or “3-4S” (I use two controllers that is why I know). There is what is called charging voltage (and it can come in different names too but do well to read your manual well); this voltage should be at 14.6V or +or -0.2V for healthy charging of your lithium battery. This means that your battery will be charging at 40amps and 14.6V = 584Watts. And this will take your battery about 2hours 30minutes to fully charge under ideal condition. But I’ll suggest you make it 5 panels if you can.

Now about your single panel giving you this issue, well one thing you need to note is that the weather today (from my end) is mostly cloudy. And I can’t judge my panels based on it, and it’s been this way for the past few days; looking as though the rain wants to fall, but it never did.

Secondly, get a multimeter, maybe a DT830L model, which is a 10amps Dc current meter, it’s around 9k or so when I bought it. Connect it to the terminals of your panel and confirm the current coming from your panel. This way, you are certain if your panel is good or not. If your panel is reading closely to the rated capacity just like that in your controller, then it is the weather. And you can only hope for a sunny day.

I know this is a long read, but I’ve been in your shoes, and I try to make sure you get all the answers you need from this reply.

My solar panel, just like your yours, in those days will be giving me a max of 4amps. I washed my panel during one of the sunny days in January, and I was getting a whooping 17.1Amps (i.e 5.7Amps per panel) from 3 panels of the same Africell 200watts , I attached the picture below. Some days I could get close to 18amps as well.

Be that as it may, I am not a professional in Solar and I don’t have much experience like some people here. I’m more of a DIY guy, who loves experiments.
All the best bro. If you still have questions, you can still tag me. And please pardon my typos.

You have not really answered my question
Firstly I have a multimeter and I was the one that advised you to get one in arena
Secondly I can't get 60a mppt cos I already have 30a which is okay for 100ah battery...
Thirdly I can't get 4panel on 30a controller... If I can get 20amp from the mppt am okay.
I just want to know how you where able to solve your ampere problem...like I said am using pwd and am getting 24v 6amp from my panel....but this new mppt is giving me 15v and 2.6amp which is way below the pwd controller.. I just want to know what you did to solved the ampere problem cos I know you are getting 2amp before and you where able to solve the problem.... Note my multimeter read 21v 3.4a this morning despite bad weather and at the same time my mppt read 15v and 2.6 amp...that is my concern why low ampere from mppt instead of getting more ampere from it.... I hope you understand me now

Lastly pls what is your ampere reading on mppt and pwd

BigDickProblems:
It’s a PWM charge controller that shows the readings.
This is from this morning:
Panel Reading by 9:00am
Twin Tech 12.5V 1.0Amp = 13.75Watts
Africell 12.5V 1.0Amp =12.5Watts
Parallel Connection 2.6Amp 12.9V =33.54Watts

Panel Reading by 9:26am
Africell 13.0V 1.8Amp = 23.4Watts
Twin Tech 12.9V 1.5Amp = 19.35Watts
Parallel Connection 2.9Amp 13.2V = 38.28Watts

This is way too low for a 360Watts panel. What could be the issue here?

@BigDickProblems
Pls I need your help on how to solve my mppt new controller....I was using 200w africell panel with pwd controller...so I decided to get myself 100ah lithium battery with 30a mppt controller in other to protect my new battery and also to get more ampere....note I usually get 24v and 6amp from panel directly and 6amp from my pwd of course the excess voltage will be wasted. But since I installed this mppt control am getting 15v from panel and 2.6amp and a total wattage of 34watts from a panel of 200w .... I thought the mppt was not okay so I have to waste money on transport to return the mppt controller, I was given another one and I ask them to test it to confirm if the mppt is okay....they tested it and show me the result via video 56v and 20amp although I don't know how many panel they use for the testing....i installed the new mppt controller this morning and am still getting 15v and 2.6amp and a total wattage of 34watts from 200w same as the one I returned....I don't really understand what is going on cos my panel read 24 and 3amp....I expect the mppt to boost my ampere but is decreasing it...
