Sorry you are having issues, where did you buy the Charger? Victron support is supplied through the dealers or through the Victron Community support forum. If you got it off Amazon then try contacting the seller. Did you go through the app and make all the correct settings? If your batteries are charged up, it won’t show any wattage from solar, only reports when there is an output. The chargers are pretty basic, here is a link to the Victron community, whenever I have had issues, I have gotten answers there, there are Victron employees on the sight.

Here is an article from Battleborn of setting up the charger.
