I have a BMV-712 smart that I would like to control an MPPT 250/100. I have the BMV in relay mode and it is wired in the back to the COM and NO ports. It connects to the MPPT relay plug. I have it in remote mode. I have set the BMV to cut off at 50 volts.The MPPT is charging. To test to see if it will cut off on an over voltage condition, I lower the high voltage relay setting to 46 volts when the battery is at 48 volts. The MPPT keeps charging. How do I get the MPPT to stop charging according to the parameters that I set in the BMV? I would like to also cut off charging at low temperature based on the installed temp sensor.
