I did a little testing of the panels today before I mounted them on the roof. The panel voltage checked with a Fluke Multimeter and no load,wired in series and in pretty much full sun was 40.3 for the matched pair (2 Kyocera KC50 50 Watt) and for the unmatched pair(1 Kyocera KC50 50 W & 1 Newpowa 50W) it was 41.7. Does testing the voltage this way tell anything and does this seem like these panels are a pretty decent match?
Thanks!

What would the IV curve look like if one series panel looked like this?
Would controller algorithm 'pick' the correct mppt?

In theory, a quality product can be manufactured anywhere. In reality... take your chance.
IMO, 36V is pushing the limits.

If you trip the panel switch, the only consequence will be that the battery will stop charging.
36V is right there at the max Vmp of 2 panels in series. If you believe in quality of Littelfuse Suzhou products, go ahead ๐

Not having much luck coming up with a suitable DC rated switch for the solar panel wires that connect to the controller. I am not real sure what the max voltage and amps I would see in these wires with the panels series/parallel wired. I have been looking for a DC rated switch with a minimum of a 40V and 10A rating and screw terminals. Would this be satisfactory?
