The invention discloses a lighting, monitoring and alarm integrated system for a micro-grid. The lighting, monitoring and alarm integrated system for the micro-grid consists of a plurality of groups of solar photovoltaic assemblies, and a self-checking module, a public road surface lighting assembly, a family lighting assembly, a video acquisition and transmission assembly, a voice information transmission assembly and a control platform which are connected with the solar photovoltaic assemblies; the solar photovoltaic assemblies supply electric energy. According to the lighting, monitoring and alarm integrated system for the micro-grid, road surface lighting, public security and road lamp theft prevention are realized by combining the solar photovoltaic assemblies, road lamps and video acquisition nodes; family lighting, public security, theft prevention and elderly care are realized by combining the solar photovoltaic assemblies, the family lighting assembly and the video acquisition nodes; self-checking is performed through self-checking module, and the alarm is completed through the control platform, so that the functions of equipment maintenance, daily security, family care and the like are realized easily; the system can work normally with electricity difficulties and without professional maintenance staff in rural areas, is low in investment, low in cost, convenient to use, and is an integrated system which is worth popularizing.
