The off-grid solar system includes the solar panels, charge controller, batteries, inverter, Bluetooth module, and wirings.
First, the battery should be hooked up to the charge controller with tray cables. Second, then connect your solar panel to your charge controller with adaptor kits.
After the wiring connections, you will need to set your battery type using the SET button, and then the controller can take care of the rest. The LED Indicators and SET buttons are found on the OUTPUT side of the Rover Boost.
