The invention discloses a solar inverter based on UCOS (Micro Control Operation System) control. The solar inverter comprises a storage battery for outputting 12V direct current, a controller, a main control chip, an ADC (Analog to Digital Converter) detection unit for detecting alternating current, a power supply module for raising and lowering the voltage of direct current, a wireless module, a sensor module and an inverter for inverting the direct current. A touch screen is designed. The working mode of the inverter can be controlled, the running state of a system is displayed in real time, information acquired from each path is displayed, and relevant function curves are drawn, so that convenience is brought to later data integration, wireless control can be realized, and the acquired information can be transmitted. The solar inverter is particularly suitable to be built on remote unattended solar power stations; moreover, the equipment is low in hardware cost, is easy to learn and use, and is convenient to popularize.
