Make sure to FIRST lower each terminal hatch by screwing the terminals counterclockwise (CCW) to expose the wire terminal hatch to the open position. THEN secure each cable by rotating the screws clockwise (CW) to the closed position. 【Remote Monitoring】 The RS232 communication port allows the Renogy Rover charge controller to communicate with the DC Home app and Renogy ONE M1 via the Renogy BT-1 Bluetooth module (highly recommend to add-on ). This will enable you to monitor the status and productivity of your panels on the go.
