Everyone should watch the above video to see and excellent example of the problems with wiring several panels in series. The RV in the video has all 6 of the panels wired in series. The total amps from all 6 panels at the start of the video is about 37amps. As they tilt each panel there is almost no increase in output until they tilt the last panel. Then the output jumps from about 38 amps to 51 amps. This also shows the affects of shading on panels in series.Kevin Means said:By the way, here's a YouTube video of a couple who has the same system we have - six 160 watt Grape panels with an FM80 controller. Watch how tilting them dramatically improves their output. It's the same output we see - both before and after we started tilting our panels. https://www.google.com/url?q=https://www.youtube.com/watch%3Fv%3DG01A51L-5Vc&sa=U&ved=0ahUKEwjckPCkqY3VAhUnsFQKHQRcDT4QtwIIIDAC&usg=AFQjCNGoB1NZ-EZWFkk6J0GcWgp41i0ZNQ
