I have connected everything according to the instructions. When not connected to the car, the solar is coming in via a voltage relay switch. In the app it's showing 19 volts coming from the solar panel and I'm get the error: 'charging disabled' and 'remote input not activated'.
Am I doing something wrong? Do I need a regulator to bring that voltage from the solar panel down? What am I supposed to do with the jumper?
Help greatly appreciated.

Chris
