I currently have a BMV-712 Smart installed in my boat together a solar installation and it works great.
The SOC relay function indeed works as intended, but it would be nice to have similar functionality independent from the discharge floor.
What I am looking for is a way to use the BMV relay to signal my third party solar charge controller to keep my LifePo4 batteries at a SOC between 60 and 70% while the boat is not used. If I had Pb batteries I could just leave them fully charged, or use the Low voltage relay function. However the voltage curve on the LifePo4 batteries are just to flat for this function to make sense. I have my discharge floor set at 20% now (as recommended by Victron) and would prefer not tot change it in order to have this functionality.
Any thoughts from Victron on this? I don't think I am the only one who would be happy if you included this in a future FW update.
Kind regards,
Simen
