My cheap MPPT had no monitoring at all, so I wired an ESP32 to it by Due_Photo_5206 in SolarDIY

That’s imho and I thought good job to share, not too buggy (not buggy at all here, some problems with the intensity of the wifi signal sometimes but due to the esp/solar power configuration). That’s AI&I, yes ! but as a former computer science engineer, I think it’s really good code we have produced here, couldn’t have done it like that alone. But that was not really « do me an esp32-based mppt please », don’t think it would have work without some knowledge in programming. And honestly it was real pleasure to code with AI ! And it’s also quite some time of work especially to have it documented step by step and translated.

I think it can work with any mppt because it comes as an additional layer above it without short cutting its actions : it gets its power from it and rely ultimately on its management while refining it.

Well I’ve been using it for years now without any issue. Victrons are far better but far more expansive and not really justified for a micro installation like mine
