The epever controller specifies per cell I think (mv/degrees C/2V) default is -3mv.Or disabling temp comp if the system permits that.
Yep. Higher voltage when cold, lower voltage when hot.
Agreed.
Agreed.
Show us.
Temp comp is expressed as a total or a per cell value. You sometimes have to do the math to get it right.
My Trojans were -.005V/°C/cell
I had 24 cells, so I had to enter, -.005 * 24 = -0.12V/°C or -120mV/°C as the Victron MPPT wanted to see it.
Datasheet is here.
Says temp coefficient is -30mv /degrees C
I'm assuming that would be per 12V so would that make it -5mv that I set the controller to?
