I want to cut off all charging to my lithium batteries when below a certain temperature. My system includes a MPPT, BMV, Multiplus, and a Venus.
My original plan was to:
- Connect the BMV temp sensor to the battery, link the BMV and the MPPT and cut charging when under some predefined temp.
- Additionally, use a relay on the BMV to trigger an assistant on the multiplus to cut charging at the same temperature.
However I am beginning to think that maybe I can do all of this on the Venus. Can you please provide me with a recommendation that Victron supports?
Thanks and sorry for some duplicate posting but getting this question answered hasn't been easy!
