Eco-Worthy MPPT and Solar30 PWM Test
Did a quick backyard test of my two solar controllers using the actual trailer wiring etc as intended for camping with solar later this month. Got some blue sky, no clouds. The Eco-W on the 230w p...

To add
The normal working voltage of my 230w poly is 34-35v. I've never tested Voc at altitude but I'm sure it's higher by a bit. There have been many sub freezing mornings up there but the panel isn't exposed to intense light all at once either. It has a gentle start in lower light and by the time the sun is fully up the panel is warmer and the VOC already limited.
So I think it would be pretty hard to get the voltage spike I saw pulling the cover off. Maybe a sudden break in heavy cloud cover on a sub freezing day could do it. Still it would be good to have some head room on any controller.
