Was this what I was supposed to learn after 5 years of engineering in a naija uni?













Op.. How many units of these can you make large scale?..

updated mppt.. Up to 200vdc input

updated mppt

Inside the casing .

I would upload a more detailed MPPT design
but on a dedicated site. I would make the URL available soon

that would be very nice sir, looking 4wrd to that

This is really inspiring. This is what ive been discussing with Bigrovar. With integrity and adherence to international best practices, I see you conquering the African sub region.

I'm impressed. OP keep it up. We need to patronise Made in Nigeria product. Chinese don finish me

Nice, Let's keep the Good work of MPPT active, I successfully installed 120v unit recently
, modifying my MPPT for RoHS compliance.. keep it up Bro ....

Thanks, I am still be posting more design details at nisol . com . ng

Meanwhile do you produce your boards in China? how many days does it take for delivery.

my PCB is produced in Singapore, and takes 18 days to arrive from the day I sent it out..

Please share your contact details

go and use local method. etching ur pcb with chemical

This attempt of mine of making a PCB may help, see here >>> http://jeansunday..com.ng/2017/07/make-your-printed-circuit-board-pcb_23.html

Thanks. I'm doing that now

Our MPPT is featuring this packaging, and will soon be available for purchase in Nigerian market ��. moved from pic16f876a to more powerful processor for better performance. designed by Ghost™ .

we now have our three phase signals, our updated mppt is featuring 3phase interleaved mppt, 98% efficiency. limited to 60a, input raised to 300vdc, output up to 96v . Ghost power technologies .

Preparing our mppt for Nigerian market.

Great effort man.

I am presently working on an arduino based mppt 20A solar charge controller but not done yet, will like to work with interested people

I have completed my 45a version, working well , using 16bit pic processor.

At work, and the internal structure of the mppt .

Bottom view !

How can we learn this mppt sir

nisol:
Objectives:
Considering the high cost of commercially available MPPT based solar charge controllers,
I decided to build one for myself at a much lower cost and secondly, to have customizable features.

Methodology:
Solar charge controllers are majorly DC buck converters.
There are several methods of achieving MPPT based charge controllers.

These briefly are:
Perturb and observe, Incremental conductance, Current Sweep Method, Constant voltage.
The first four methods involve storing the PV (photovoltaic) array Voc (Open circuit voltage) /current
against the controller output voltage Vout/current with varying pulse widths applied to the buck converter.
The stored points are then compared and that with the maximum power transfer value is then used to
switch the semiconductors in the controller for a fixed interval after which the process is repeated.

Good evening sir please how can I reach you because I'm working on a solar panel project?
