Thanks, I have msview but never used the logging feature before. It will do nicely.
One odd behavior that both controllers seem to do... when the sun is low or the panels
are shaded, the voltage is typically higher, 16v-18v.
When the panels are in full sun, they both drop down to 15v. Is that some kind of physics issue or ??? I'd rather they run higher voltage obviously, but have no way of controlling it.
Maybe I'll try rigging
a gopro to take pictures of the panels and then I could correlate the data with the shading... but I may just drink beer
24 hours until we're off the dock! of course we're due for rain this week... so the sun will suck when I need it! but hey if it's a little cooler I'm all for it.
