Technical Field
[0001] The utility model relates to the technical field of photovoltaic inverter monitoring, in particular to an intelligent monitoring device based on distributed photovoltaic inverters. Background Art
[0002] Photovoltaic inverters convert the variable DC voltage generated by photovoltaic (PV) solar panels into alternating current (AC) at mains frequency, which can be fed back into commercial power transmission systems or used in off-grid power grids. PV inverters are a key balance of system (BOS) component in PV array systems and can be used with conventional AC-powered equipment. Solar inverters have special functions for PV arrays, such as maximum power point tracking and islanding protection. During use, PV inverters are often placed inside cabinets and monitored using monitoring devices. However, most current monitoring devices are fixed, making it difficult for personnel to promptly detect and address the fault when a PV inverter fails. Therefore, we propose an intelligent monitoring device based on distributed PV inverters. Utility Model Content
