I should have clarified - 10 awg carrying 17a at around 120 to 150 ft, depending on the string of panels. I think that's close to max but maybe a little over.
Glowing at night - I'm gonna try to avoid that! Other than scorpions and horn worms when I hit them with a black light.
I have a pair of inverters that create glow lights to match the glowing wire, don't have to even have the light switch on. Maybe you can buy them off James at a discount?
A few videos, I had thought maybe I had aliasing causing the distortion with the LV6548 waveforms on a longer time sweep, however I've now captured the waveform of the LV6548 with PV input. It was not aliasing.
Here is the MPP Solar LV6548 output power with PV input this morning.
