Technical Field

[0001] The utility model relates to an optical storage cabinet system applied to a gate port of an open-air parking lot. Background Art

[0002] Some existing remote areas have been renovated and built into unmanned open-air parking lots.

The renovation of some existing remote open-air parking lots often requires laying cables from far away, resulting in increased costs, and the need for follow-up maintenance and laying cables later. Once the power supply is lost due to cable problems, it is difficult to troubleshoot the problem and seriously affects the normal operation of the open-air parking lot, thereby affecting the parking fee profit.

[0018] MPPT controller, Maximum Power Point Tracking (MPPT) system is an electrical system that adjusts the working state of the electrical module to enable the photovoltaic panel to output more electrical energy. It can effectively store the DC power generated by the solar panel in the battery, which can effectively solve the living and industrial electricity consumption in remote areas and tourist areas that are not covered by conventional power grids without causing environmental pollution. The MPPT controller can detect the power generation voltage of the solar panel in real time and track the maximum voltage and current value (VI), so that the system can charge the battery with maximum power output. Applied in solar photovoltaic systems, it coordinates the work of solar panels, batteries, and loads, and is the brain of the photovoltaic system.

[0019] The photovoltaic storage system of the utility model provides AC220V power supply for the entire open-air parking system alone, and does not need to be powered by the power grid, reducing the construction and later operation and maintenance costs.
