MPPT Temperature compensation setting

Batteries.pdf

According to the battery profile document attached, what should be my temperature compensation setting for 2 x 6 volts wired in series? I have an SmartSolar MPPT 100-50.

Thanks!

Hi @MichelBeausejour

from your document:

Please note the voltage settings displayed in the IUI with Pulse Termination Charge Prole graph, corresponds to the set points at 25°C (77°F). For temperatures below 25°C, adjust +0.005VPC/°C . For temperatures above 25°C, adjust -0.005VPC/°C

VPC = Volt Per Cell

so for 6 cells, multiply by 6 (0,03V/C)

Thanks @Daniël Boekel (Victron Energy Staff). I thought that I should be using the values from the IUU profile. Am I not correct?
