First off, thank you sixfab team for making an excellent product! I’m very impressed so far with both the hardware and the API. I have a python script feeding our own database and it’s running perfectly.
My questions is about solar. I’m not an expert but am curious if feeding a 12v 50w or 100w panel directly into the J4 terminal is the correct way to do it. Do we need a charge controller upstream or can the hat handle direct DC input? I’m considering one of those $80 panels on amazon but would rather not fry my system before asking.
