I’ve just received emonpi board today had little problem getting the image flashed and reading my solar export but now need to use this data
I’d like to capture some of the excess energy in batteries in the process of harvesting 18650 cells to make the store
Any advise on how to drive the charger or charge reconstruction would be good
