As the core equipment of photovoltaic power station, photovoltaic inverter has high value and its reliability has a great influence on power generation. Photovoltaic power plants are generally built on the seashore in harsh environments such as humidity, salt spray, and typhoons, and inverters are easily affected. As a important electronic component of the inverter, the precision resistor also needs to ensure the normal operation of the inverter in such a harsh environment. In order to ensure the normal operation of the inverter, how to choose the precision resistor?

 
First of all, in the selection of inverter components, the first-line resistance brand is preferred, and the real material can highlight the distinctive charm under the extreme environment.
In terms of precision resistors, precision resistors are important components of photovoltaic inverters. Its quality will directly affect the life of the machine. Some brands of high-precision resistors can withstand 85°C high temperature and 85% humidity. The inverter can still operate stably under the harsh environment of high temperature and high humidity.
 
 Secondly, the inverter should use moisture-proof, anti-corrosion, waterproof and other performance materials in other materials selection. The appearance of the inverter is also a threshold for protecting the precision resistor inside. The choice of moisture-proof, anti-corrosion and waterproof materials can reduce the damage of other electronic components in the circuit. The precision resistors can also work normally, ensuring that the inverter can convert more power into the grid. 

When selecting the inverter, the inverter will usually choose the inverter of the big brand, which can reduce the damage of the inverter and ensure the stability of the photovoltaic power generation. At the same time, the big brand inverters will use high-end high-precision resistors in the inverter circuit, which can make the precision resistors work normally and stably in the inverter, and can also improve the service life of the inverter.
