Embodiment

[0037] figure 1 It is a system block diagram of a solar power supply device for online monitoring, including multiple sets of solar panels 101, multiple sets of MPPT charging controllers 102, energy storage unit 103, detection unit 104, wireless module 1105, main control system 106, and multiple output modules 107, multi-channel load 108), wireless module 109, and remote monitoring and setting system 110. Multiple sets of MPPT charging controllers 102 have multiple sets of solar panels 101 at their input, and an energy storage unit 103 at their output. The energy storage unit 103 provides energy for the main control system 106 and the multiple output module 107 . The input end of the multi-channel output module 107 is the energy storage unit 103, the output end is the multi-channel load 108, and the main control system 106 realizes the shutdown of load power supply by controlling various switches K1-Kn. The detection unit (104) collects energy information of the energy stor...

Description

technical field [0001] The invention relates to the field of distributed photovoltaic power generation, in particular to an online monitoring device powered by solar energy. Background technique [0002] Wireless sensing and remote monitoring are one of the important means to ensure social safety in production. Due to the limitation of geographical environment and practical conditions, most remote detection points and wireless devices cannot obtain mains power. Using solar green energy to power them is an ideal and convenient measure. However, due to environmental and site constraints, solar panels often cannot effectively guarantee long-term power supply for multiple loads when generating and storing energy. How to prolong the online working time of loads and ensure the long-term operation of key loads has become a priority issue for solar power supplies. Contents of the invention [0003] The object of the present invention is to provide an on-line monitoring device po...
