Title: Open source solar controller
Post by: 172pilot on September 12, 2021, 03:41:54 pm

I stumbled across this project:  https://www.youtube.com/watch?v=ShXNJM6uHLM (https://www.youtube.com/watch?v=ShXNJM6uHLM)
Listening to his video, this sounds great - I would love to hear Dave's opinion on the build, and if there are any safety concerns, and/or curious if anyone has built this or something similar?

There are loads  of designs available, some better than others. I have made a few of my own design that Ill post later, they all work but i'm still not happy with the current capacity. I stopped making them last year as I could not get parts anymore - the ACS sensor in that design you posted is still out of stok everywhere although there is a drop-in replacment by TI available. I had just switched from using a PIC16F1509 to a dsPIC33EP64GS504 in order to get ready for a multi-phase buck design but now I can't get that micro anywhere.
