Photovoltaic (PV) power generation systems are more and more widely used in marine ships and marine engineering. In the process of power electronic transmission, off-grid inverters will convert unstable DC power into stable AC output. Based on the PV power generation systems, this paper aims to explore the design and application of PV off-grid inverters in marine engineering. The research results show that off-grid inverters consist of boost modules, filter modules, and inverter module; the hysteresis controller can achieve transmission stability in about 0.04s; the communication protocol of the off-grid inverters used in marine engineering is the controller area network communication, which can effectively support real-time control or distributed control, achieve real-time communication between nodes, and improve transmission reliability and flexibility throughout the local area. The research findings provide a theoretical basis for the efficient use of PV power generation systems in marine engineering.
