Problems solved by technology

[0003] but figure 1 The locations of the various components of the off-grid system shown are scattered, and the controller 12, the inverter 14, and the battery pack 13 are generally placed indoors; since the photovoltaic components convert light energy into electrical energy, they must receive sunlight when working. Therefore, the photovoltaic modules must be placed outdoors or on the roof, and even some centralized photovoltaic off-grid systems will be installed in remote areas, unattended, and the modules are not working at night, which is easy to be stolen

Abstract

The invention discloses a photovoltaic off-grid system which comprises at least one photovoltaic assembly, a controller, a storage battery, an inverter and a load.The controller is connected with the photovoltaic assemblies, the storage battery and the inverter separately, and the load is connected with the inverter or the storage battery; each photovoltaic assembly comprises a photovoltaic panel and a metal frame; the controller comprises a main control module and a monitor module; the monitor module and the metal frames are connected through wires to form monitor loops; the monitor loops are used for monitoring the photovoltaic assemblies and sending monitoring signals to the main control module through the monitor module; the main control module is connected with the monitor module in the monitor loops and used for receiving the monitor signals sent by the monitor module and judging on-off of the monitor loops according to the monitor signals to judge whether the photovoltaic assemblies are moved or not.According to the photovoltaic off-grid system, whether the photovoltaic assemblies are moved or not can be monitored, and therefore the photovoltaic assemblies can be prevented from being stolen.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic off-grid system. Background technique [0002] Solar photovoltaic power generation system, as one of many solar energy resources, has been widely used in people's lives today. Photovoltaic off-grid system is a device that uses solar energy to generate electricity. Such as figure 1 As shown, the existing photovoltaic off-grid system generally consists of a photovoltaic module 11, a controller 12 connected to the photovoltaic module 11, a battery pack 13 connected to the controller 12, an inverter 14 connected to the controller 12, and a load 15, etc. Composition, wherein the load includes AC load 16 and DC load 17. The photovoltaic module converts solar energy into electric energy when there is light, and charges the battery pack 13 through the controller 12 ; when there is no light, the battery pack 13 supplies power to the AC load 16 throu...
