Abstract ∵ In response to the challenges posed by the high cost of water lifting and electricity in hilly and mountainous regions，the Jinping Town Modern Agricultural Science and Technology Industrial Park project in Yibin City has innovatively proposed a water lifting technology based on photovoltaic（PV）-energy storage microgrid， and established a PV pumping system on the basis of direct supply of green power. Its single-unit power broke 355kW for the first time， the single-stage head of the PV pumping station exceeded 800m ， and the installed capacity of PV was 3563.52kW . To meet the demand for high efficiency over a wide operating range and mitigate the instability of thesystem caused byfluctuations insolar iradiance，an effcient low-specific-speed hydraulic model was developed and complemented by a PV-integrated energy storage system，ensuring that the solar PV water lifting system operates efficiently and stably.This technology effectively solves the problem of high-cost water lifting，promotes the comprehensive utilization of water resources，andcontributes topost-resettlement livelihood support and rural revitalization.Furthermore，it provides an important technical support for the future application of high head PV-energy storage water lifting.
