Embodiment Construction

[0023] The solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments,

[0024] Such as figure 1 Shown:

[0025] Working principle of the present invention is:

[0026] 1. Power management function. The system has intelligent features, and performs fully automatic power management on systems connected with photovoltaic and battery dual power sources, and realizes complex automatic switching and combination of photovoltaic power sources and battery dual power sources. The system can be connected to photovoltaic or storage battery alone, or it can be connected to photovoltaic and storage battery at the same time. The system identifies the power supply through automatic inspection and gives priority to photovoltaic power supply.

[0027] When the system meets the conditions for pumping water, ① it can give priority to the use of photovoltaic power supply, and it can run in the state of driv...
