Is this correct?
Current Equipment:
Multiplus II 12v 3k 50 120x2
Temp sensor for MP
Smart Shunt 500
4 Litime 230AH (920 AH) 12v configuration.
MK3-USB adapter
Planned additions:
Cerbo GX/touch
3,350 watts of solar, running 2 separate strings
Two Smart Solar MPPT 250/100 chargers.
If that's the case, the MP temp sensor connected to the T-sense terminal will supply the MP-II the appropriate temperature reading to use the MP-II's low temp charge protection feature. It can also be used as the system temperature for when you get a cerbo to feed temperature data to the MPPT.
