Embodiment

[0041] This embodiment: as figure 1 As shown, a photovoltaic intelligent power distribution system includes a photovoltaic module 1, and the AC inverter output of the photovoltaic module 1 is output to the AC bus 2, and one end of the AC bus 2 supplies DC power to the load 3, and the other end of the AC bus 2 can be The DC inverter is output to the battery pack 4 , and the battery pack 4 can also be output to the AC bus 2 through AC inverter switching.

[0042] Since the photovoltaic module is used for AC inverter output to the AC bus, one end of the AC bus supplies DC power to the load, and the other end of the AC bus can be DC inverted and output to the battery pack, and the battery pack can also be switched for AC inverter output. Based on the AC bus, because it can communicate with the bidirectional inverter and realize the seamless switching between the intelligently controlled photovoltaic power supply and the diesel generator power supply, its working principle is that th...

Abstract

The invention belongs to the technical field of photovoltaic systems, and in particular relates to a photovoltaic intelligent power distribution system. The AC component of the PV module is outputtedto an AC bus, and one end of the AC bus is DC-powered to the load. The other end of the AC bus bar can be DC-inverted and outputted to the battery pack, and the battery pack can also be switched by the AC inverter to be outputted to the AC bus. The system solves the problem that the prior art has the inability to maximize the utilization of photovoltaic energy and achieve stable AC power supply. With maximum use of photovoltaic energy, the system provides a stable foundation for photovoltaic power supply, meets diverse power capacity requirements, and has the beneficial technical effects of flexible expansion.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic systems, in particular to a photovoltaic intelligent power distribution system. Background technique [0002] Domestic conventional off-grid photovoltaic systems generally generate DC power from photovoltaic modules, and then charge the battery pack through the charge and discharge controller. The power supply for the load is achieved by inverting the DC power of the battery into AC power through an off-grid inverter. The existing technology has the problem of not being able to maximize the use of photovoltaic energy and achieve a stable AC power supply. Contents of the invention [0003] The present invention provides a photovoltaic intelligent power distribution system to solve the problem in the above-mentioned background art that the prior art cannot maximize the use of photovoltaic energy and realize stable AC power supply. [0004] The technical problem solved by the present inventio...
