I think the temp adjustment feature, whether remoted to the battery or not, just adjusts the controller's set points for temp. Has no effect on panel voltage or MPPT bucking AFAIK
With high temps the battery voltage set points would be adjusted lower so the spread between battery voltage and the lower panel voltage might be maintained? Is that what you mean?
FWIW my controller is right beside the batteries so its non-remoted temp comp should be about the same comp as a remoted one. I am still getting the MPPT heat loss effect as described.
Shows the Eco-W (internal temp comp) near the batts (two T-1275s and four 6s--two of the sixes off to the right of this photo) Now have the Solar30 disconnected and the whole six batts as one bank off the Eco-W since the 130w panel was sold that the Solar30 did. Am getting to Float mid afternoon and full SG by dark most days on the 230w tracking in the contraption.
