MW that does look like a simple solution, I can get a 24v fan like that from Aliexpress delivered to my door for about$5.
So you are saying that because the fan is 24v vs 12v it will not run unless the panels are charging at around 19v? And the voltage off the battery that I get through my pwm Trimetric won't run the fan because it's too low?
That sounds like it makes sense but just to belabor the point (for the moderator's benefit), just because the fan isn't turning, is it not still using power? The magnets will still be charged just not enough to spin the fan?
