Grid-connected solar photovoltaic power generation system additionally arranged on ship

The utility model belongs to the field of ship green new energy, and relates to a grid-connected solar photovoltaic power generation system additionally arranged on a ship. And then the direct current is converted into three-phase alternating current required by the ship through an inverter, and the three-phase alternating current is merged into a ship main power station as a total output port of the solar photovoltaic power generation system through a photovoltaic grid-connected cabinet, and is transmitted to a ship load for use through a ship power grid. According to the grid-connected solar photovoltaic power generation system additionally arranged on the ship, operation and use of a ship fuel engine generator are effectively reduced, and solar photovoltaic assembly strings can be flexibly arranged in a non-operation area of an open-air part of a ship main deck, so that the total loss of electric power generated by solar photovoltaic assembly equipment is reduced, and the service life of the ship is prolon
