I have a 100 / 30 MPPT and I have three 200 watt solar panels attached and the bulk state turns off automatically.. I heard if the solar voltage goes below 5V higher than the Battery Voltage it automatically turns off.. why would this be the case? Why would the voltage drop and the bulk automatically turn off which stops my solar panels from charging. This doesn’t make any sense. If anyone can help me figure out how to fix this problem? Thank you
