In order to meet the convenience of carrying the photovoltaic water pump system, it is necessary to solve the problem of mobile irrigation in remote areas. To this end, this paper designs a portable inverter system for photovoltaic water pumps. This article takes the climatic conditions of northern Shaanxi as the background, and considers the influence of slope, aspect and shade on photovoltaic panels, which can be used as a reference for the parameter matching range between photovoltaic panel installation and system power. According to the requirements of off-grid systems for photovoltaic inverters and the characteristics of portable inverter systems without batteries, a single-stage transformerless three-phase bridge inverter circuit is selected through the comparison of inverter topologies. On this basis, The scheme of the inverter system was determined; secondly, in order to solve the loss in the circuit and improve the efficiency of the inverter, a soft start was adopted in the main circuit, which reduced the loss of the large current to the wire and the circuit during the startup process.
