So you folks have got me thinking again about adding some portable solar to the existing fixed solar.
Curious what happens when the solar panel V exceeds a PWM's max input spec. (on really cold, bright sunny days)? Do they just shut down or blow up ... or? IOW any harm to them?
Looking at two 36 cell panels in series going into a 24V battery bank via PWM. Each panel with Voc of 23.39V @ 25C and maybe 51.5V total at 0C (estimated roughly from that graph posted earlier).
Have seen specs for max solar V of <50V in cheap PWMs and up to 60V in more expensive PWMs.
