Problems solved by technology

However, when the traditional photovoltaic power generation system is used in the plateau, due to the frequent failure of the photovoltaic power generation system in the plateau environment, the system may be powered off, and the AC load discharge times are too many and the battery discharge depth is too low, which will reduce the service life of the battery. So that the service life of the system is reduced
In addition, it is difficult to analyze the operation failure of power stations in plateau areas, coupled with inconvenient transportation, this will lead to long-term power outages of photovoltaic power generation systems, which has brought great inconvenience to power users

Abstract

The invention discloses an energy storage type photovoltaic off-grid power generation system for plateau and a remote monitoring method. The energy storage type photovoltaic off-grid power generationsystem for plateau comprises a solar cell module, a solar charging controller, a storage battery pack and an off-grid inverter. The solar cell module is connected with the solar charging controller, the solar charging controller is connected with the storage battery pack, and the storage battery pack is connected with the off-grid inverter. According to the energy storage type photovoltaic off-grid power generation system for the plateau, problems of capacity reduction, performance stability, high conversion efficiency and the like of a high-altitude operation environment of the plateau are solved, a service life of the power generation system is greatly prolonged, the problem of frequent maintenance is effectively avoided, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic off-grid power generation, in particular to an energy storage type photovoltaic off-grid power generation system for plateaus and a remote monitoring method. Background technique [0002] The western plateau region of my country is very rich in solar energy resources, and 2 / 3 of the areas have an annual sunshine time of more than 2000h, which has good conditions for utilizing solar energy and provides sufficient energy for the power supply of photovoltaic power generation systems. However, when the traditional photovoltaic power generation system is used in the plateau, due to the frequent failure of the photovoltaic power generation system in the plateau environment, the system may be powered off, and the AC load discharge times are too many and the battery discharge depth is too low, which will reduce the service life of the battery. So that the service life of the system is reduced. In ad...
