Larry, This was an AEE product, but we no longer sell it. It was made for us by Apollo Solar. You can check with them to see if any are still laying around. They bypassed a module when the temperature dropped to 40 degrees F. You could use SolarEdge inverters and Optimizers and have strings of up to 25 modules with no worry about overvoltage in cold weather.

I can't find any info by Goggling. Some customers in the FAR north, ay, can see > 40° below zero with bright sun and snow reflection. I want to be able to switch off one or more modules in a string for protecting the controllers. Thank you, Larry Crutcher Starlight Solar Power Systems
