A marine vessel power supply system (50) for a marine vessel (1) including an electric motor (41) to rotate a propeller (23) includes an inverter (61) to supply electric power to the electric motor (41), a battery (B2) to supply electric power to the inverter (61), and an electronic control unit (55) configured or programmed to control the inverter (61). The inverter (61) includes an inverter circuit (79) to convert DC electric power supplied from the battery (B2) to AC electric power, a voltage detector (84) to detect the voltage in a wiring between the battery (B2) and the inverter circuit (79), and a microcomputer (86) configured or programmed to communicate with the electronic control unit (55) and to control the inverter circuit (79) according to a command supplied from the electronic control unit (55). The electronic control unit (55) calculates an SOC estimate indicative of an estimated state-of-charge value of the battery (B2) based on a value of the voltage detected by the voltage detector (84) and acquired from the microcomputer (86).
