Abstract

A photovoltaic inverter and a control method thereof, and a photovoltaic system. The photovoltaic inverter system includes a voltage conversion circuit, an inverter circuit, and a controller. The controller is configured to increase, based on an output power of the inverter circuit in a current time period and an output power of the inverter circuit in a first time period, an output power of the inverter circuit when the voltage conversion circuit does not work in a maximum power state. An increase of the output power of the inverter circuit is an estimated power increment value of the inverter circuit so as to stably increase an output power of the inverter while ensuring stable operation of the inverter and safe use of a power component, and improve power supply efficiency of the photovoltaic system.
