I have a new setup of 2x100 watt windynation panels in parallel with a P30L controller connected to 2x 12v deep cycle batteries also in parallel. I have set the OVD on the controller to the recommended 13.8v. However, my float voltage is constantly reading in the LCD up to 16v. I am worried that I am cooking my batteries... Am I doing something wrong? Is my controller malfunctioning? Thanks for the help!
