Requirements of inverter for physical environment

图片
Due to the high integration, compact overall structure and large heat dissipation, the  hybrid inverter  requires high temperature, humidity and dust content in the installation environment. When installing the  solar inverter , it must provide a good operating environment for the  inverter . The working ambient temperature of the inverter is rated at 40 ℃. If the ambient temperature is higher than 40 ℃ ~ 50 ℃, the rated current must be reduced. Otherwise, the temperature rise of the device will be too high, which will increase the possibility of device damage (especially IGBT power module), and have a great impact on normal and safe operation. If the working environment of the inverter fails to meet the requirements of the inverter on the working environment, it will cause high failure rate of the inverter, affect the long-term, reliable and safe operation, resulting in unnecessary economic losses. Therefore, the following matters should be paid attention to in the application of the
