Running a 100/30 Smart Controller with the BMV712 smart Monitor. Installation was completed about 11 months ago. I’m a power boat. I noticed a couple of days ago that after running the boat for the day and then anchoring, the controller would remain in float, even as the voltage dropped below 13V. The controller is set on rotary switch position 2. I have to reset the controller by disconnecting the panel (via rotary switch), then disconnecting from the battery via in-line breaker. Then reversing the process. The controller restarts and enters bulk charging mode and completes a full charging cycle. Any thoughts?
