I am super impressed with the panels thou. I will order more from the same guy 3s5p for a total of 15 panels and 3750 watts..( my unit has a max of 4000 input). look like i will need 6 more panels and one replacement ordered.
the cable that came with the battery was double ended. i had to remove one end to put on the batteries eyelet to connect to the pip. one cable popped right out with little tug. i think and hope this is the problem with power not working 100 percent of the time
