When installing the controller for the first time, it's important to ensure that the battery has sufficient voltage to allow the 40Amp MPPT Negative Ground Solar Panel Regulator to recognize the correct battery type.

To avoid voltage drop and maintain accurate voltage judgment, the controller should be installed near the battery, with wires kept as short as possible.

Please note that our BougeRV 40Amp MPPT Remote APP Control Solar Panel Regulator is designed to work exclusively with photovoltaic panels as a charging source, and cannot be used with a DC power supply.

After making any changes to the battery settings, be sure to disconnect both the solar panel and the battery from the solar charge controller, then reconnect them to activate the modified settings.

Connecting sequence: First, connect the battery to the solar charge controller, then connect the solar panel to the solar charge controller.

Disconnecting sequence: First, disconnect the solar panel from the solar charge controller, then disconnect the battery from the solar charge controller.
