It's starting to get cold here in Texas and I noticed some odd behavior this morning related to my low temp cutoff settings on my MPPTs and I'm hoping someone can help me resolve it. I have a venus gx with a temp sensor plugged in to the first port. The correct temperature displays properly in VRM and in the remote console. I purposefully set my MPPTs to cut off at 45 F to ensure temperature sharing worked. This morning the temp sensor read 42.8 F and my MPPTs were charging... yikes!
I noticed the following:
1. When DVCC -> STS -> temperature sensor is set to "automatic", the "Used sensor" displays "---" and my MPPTs charge the batteries despite violating my low temp cutoff setting. Further, when I pull up any of the MPPTs in victron connect, they do not display a temperature in the "Battery" section leading me to believe they are not aware of the current temperature and something has gone awry with STS.
2. When I manually select what I believe is the proper temperature sensor (there are several listed for some reason), all MPPTs incorrectly register the battery temp as 32 F as shown within victron connect and they stop charging my batteries.
Does anyone have any advice that might help me troubleshoot this issue? Desired state is to share the accurate temperature detected by the proper sensor connected to my Venus GX with all MPPTs so I don't kill my lithium batteries when it drops below freezing.
