How does the inverter cope with continuous high temperatures?

Many people will have a misunderstanding: the summer sunshine is abundant, is the power generation of photovoltaic power plants higher?

In fact, the power generation of photovoltaic power plants is determined by many factors, the more critical of which are irradiance and ambient temperature
.
Hot summers tend to have high temperatures rather than high irradiance, and the temperature characteristics of solar modules are negative temperature coefficients, and the power generation performance of modules decreases as the temperature rises
.
Therefore, the peak of photovoltaic power plant power generation often appears in late spring and early summer or late summer and early autumn, when the ambient temperature is suitable, the irradiance is high, and the best conditions
for photovoltaic power generation are achieved.

In addition, the inverter is usually installed outdoors, even in the direct sunlight environment, the internal temperature of the inverter will rise correspondingly in the summer high temperature environment, and the high temperature environment may also cause the inverter to overtemperature and load reduction protection, affecting the power generation of the power station
.
The following methods can help protect the inverter
.

1.
Ensure air circulation

Ensure smooth air circulation around the inverter, do not install the inverter in a small closed environment, if you install multiple inverters on the same plane, you need to ensure that there is enough distance between each inverter, which can not only ensure that the inverter is ventilated and dissipated, but also has enough operating space
for later maintenance.

2.
Avoid wind and sun

Although the inverter protection level is IP66 or IP65, it can extend the service life
of the inverter by reducing the chance of the inverter being exposed to wind, sun and rain.
When the inverter is installed, it can be installed at the bottom of the module or under
the eaves.
If the inverter is installed on the roof of the color steel tile, it is recommended to install the awning at the same time, which can not only shelter from the wind and rain, but also reduce direct sunlight, reduce the temperature of the inverter, avoid load reduction caused by overheating of the inverter, and ensure the efficiency of power generation
.

3.
Pay attention to later maintenance

After the inverter is installed, we should also pay attention to the later maintenance, and regularly clean the fan, fan cover or heat sink to ensure the heat dissipation and cooling
of the inverter.
Usually, the inverter heat dissipation will adopt intelligent air cooling technology, the fan will intelligently adjust the speed according to the internal temperature of the inverter, when the inverter works in a high temperature environment, intelligent air cooling heat dissipation technology can effectively reduce the probability of load reduction, while ensuring the stable operation of the inverter, but also extend the service life
of the fan.

The inverter has a fan fault alarm function, and the operation and maintenance personnel can receive the alarm information in the monitoring background, quickly and accurately locate the fault, which is convenient for the operation and maintenance personnel to eliminate the fan fault in time, reduce the loss of power generation, and ensure the income
of power generation.
