@AngeloCasi I'm not sure how to contact you, so I guess I'll try it here.

Just FYI, I've made a KiCAD copy of your schematic which should be a JLCPCB assembly friendly version. The files can be found here. https://github.com/jharvey/Charge_Controller

where do you need help with? :D

[SandhyTresna]

cool, just wonder is it possible to built mppt solar charge controller using buck boost converter topology. if it so what modification should i make based on your code, thanks.

[JosePineiro]

For the buck boost converter topology, you need to modify the hardware. I can help you with the code.
But think of the buck boost converter as more complicated, more expensive, and less efficient.
I recommended that you choose a battery with less voltage than your solar panel. The solar panel changes its voltage very little during its operation.

Let's have a chat between different forks? :)

@jharvey hi

@krzysztof9nowak do you like any of https://github.com/Kureigu07/FUGU-ARDUINO-MPPT-FIRMWARE commits by @Kureigu07 or his upstream @JosePineiro?

@k0rn3l any interset to pick any of the above commits?
@yangminglong? @Henn1ng? @HuaZao?

[krzysztof9nowak]

Hi,
I browsed through the commits. They seem to be just tweaks specific for specific versions of PCBs. Or am I missing something big?

In my fork I mainly refactored the code and moved to PlatformIO instead of Arduino IDE. I also have added web interface and have plans for MQTT integration with Home Assistant.

@krzysztof9nowak
Would you be interested in reviewing my copy of the hardware? https://github.com/jharvey/Charge_Controller Do you see any concerns before it's sent off to be manufactured? Do you have specific features you would like to see in the hardware?

I'm also working on a different version, where I'm attempting to combine the MPPT, BMS and pure sine inverter into one PCB. In the near future I may inquire about there might be interest in adding features to the ESP32. For example, I see the pure sine wave offers things like amps or voltage readings via serial stream. Would you be interest-able in adding features to the software for additional hardware features?

[krzysztof9nowak]

I'm quiet happy to review it, as I was planing to also make my own redesign in KiCad with some improvements. I will have a look today.

[krzysztof9nowak]

I've posted my notes in a new issue in your repo.

I'm also building a sine wave inverter. I'm experimenting with different on-grid and off-grid configurations, but I'm using same topology as you i.e. low voltage H bridge -> LC filter -> 50Hz transformer. I can work on new hardware and software features with you.

Here is also a screenshot of my very basic telemetry via website:
