We are currently Boondocking-last night the entire 12 volt system quit. This morning, when the sun came up, the Zamp controller came on with an error code of 601. We have 3 100 amp Battleborn. Yesterday, it seemed that we were not charging well with solar, but I assumed it was shade. Regardless, last night, Victron battery app showed 77% battery capacity. I am going to run our generator to see what happens. Any ideas about troubleshooting?
