The invention provides a 48V power supply system applied to a photovoltaic power generation recreational vehicle. The 48V power supply system comprises a generator, a 12V starting battery, a bidirectional DCDC module, a lithium battery, a control module, a charging and inverting integrated machine, a photovoltaic charging controller, a smart home module and a photovoltaic cell panel. Positive andnegative electrodes of an output end of a generator are connected to the positive and negative electrodes of the 12V starting battery through cables; the positive electrode and the negative electrodeof the 12V starting battery are connected to the 12V positive electrode and the 12V negative electrode of the bidirectional DCDC module through the cables; a 48V side positive electrode and a 48V sidenegative electrode of the bidirectional DCDC module are connected to the positive electrode and the negative electrode of the lithium battery; the positive and negative electrodes of the lithium battery are connected with the positive and negative electrodes of the 48V sides of the charging and inverting integrated machine and the photovoltaic charging controller; and the positive electrode and the negative electrode of the photovoltaic cell panel are connected to an input port of the photovoltaic charging controller. A line current can be greatly reduced, and a spontaneous combustion phenomenon caused by large-current heating is effectively avoided.
