Temperature sensors for inverters in photovoltaic power generation systems.infrared sensor module

　　The photovoltaic power generation system is composed of solar cell arrays, battery packs, charge and discharge controllers, inverters, AC distribution cabinets, solar tracking control systems, and other equipment. The inverter is a device that converts direct current into alternating current. Due to the fact that solar cells and batteries are DC power sources and loads are AC loads, inverters are essential. When the inverter is working, the surface temperature generated is relatively high, and it needs to be installed in a ventilated area for easy heat dissipation during installation. Therefore, it is necessary to install an NTC temperature sensor in the inverter cooling device to constantly monitor the temperature and provide feedback. When the NTC temperature sensor detects that the external temperature is too high, the drive mounting seat drives the heat dissipation cover to cover the inverter, and then uses the water-cooled and air-cooled heat dissipation mechanisms to carry out multi-level heat dissipation. This cools the inverter in high-temperature weather, reduces the surface temperature of the inverter, prevents overheating and accelerates losses, and effectively improves its service life.

　　A ground ring NCT temperature sensor, using a glass sealed NTC thermistor, has good waterproof and moisture-proof performance, will not be affected by external conditions, and can maintain optimal power generation performance and system reliability; The probe adopts a ground ring type with high sensitivity. It can effectively monitor the internal temperature of the inverter in real-time. If the temperature of the inverter is too high, it will burn out the internal components. Therefore, it is necessary to install a temperature sensor to reduce temperature faults caused by excessive temperature.
