i have been dealing with this problem since i got this set up dec 27 but for the 1st time since i got it today it when from 65 to 66 % and it is cloudy he in NY so i am hopeful that it is fix the line still says hook up a panel but i don’t care what that says as long as the battery charges so let’s see if tomorrow when the sun is out it charges friday was my dead line but up one % is better then no %
