Please tell us how your algorithm for finding the maximum power point works, according to what law the PWM control signal is generated and what is the speed of reaction to changes in input parameters. I also have a homemade mini solar power plant, which has been working for more than a year. :)

This project uses P&O MPPT algorithm. I took the code from techbuilder's mppt project and edited for my need.

Yes! A homemade MPPT with a laboratory power supply works very cool. And when connect it to a real solar panel, “unpleasant miracles” begin. :)))

NO, I have 100 A / 150 V IN / 66 V out MPPT, ESP32, onw design, own SW, it works with 90 - 98 A power all day long a few yeras and no problem. It will work at 45 - 47 *C another 30 yeras.

To power the display iam using the same 3.3v that power the esp32. And I didn't get a lcd with 3.3v supply.

Hello friend, I think there is a small error in the schematic, in GND1 and GND2 connected to the Source of Q1 and Q2, if someone were to draw the PCB using the schematic they could have problems. Would you have the firmware for Arduino instead of the ESP32? thanks.
@ElectroRetro3 ай бұрын
GND1 and GND2 are separate from Power GND, I don't have code for Arduino. This project is made for esp32.

@ElectroRetroАй бұрын
It's possible to increase Max input voltage by replacing mosfets, diodes,input capacitors, input voltage dividers and some editing in code. But I don't recommend it, because it's not safe and I didnt test this mppt with more than 90V.
