They did not come up with protocol specs but there seem to be some projects that have implemented access to the controllers.

Morningstar charge controller

Renogy Wanderer 10A Charge controller

10W panel

32W panel

2024-03 I used to have a bank of four 12V/7A gel batteries rescued from several UPSes but they died finally, I used them with the 32W panel and the Morningstar controller. When I replace the battery bank I want to get a single LiFePO4 battery, probably around 20AH. I already got the Renogy before the lead batteries died. I am holding off getting another battery so this project is on hold.

They did not come up with protocol specs but there seem to be some projects that have implemented access to the controllers.
