  5. 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.
  6. 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.
  7. Connecting sequence: First, connect the battery to the solar charge controller, then connect the solar panel to the solar charge controller.
