How to improve the life of photovoltaic inverters from heat dissipation
The photovoltaic inverter is the core equipment of the photovoltaic system, and its main function is to convert the direct current generated by the photovoltaic module into alternating current that meets the requirements of the grid.
But in fact, the inverter is not only an inverter, but a safety steward of the photovoltaic power station. The inverter also undertakes system-level functions such as the monitoring and protection of the photovoltaic array and the grid, protection of the external environment, and human-computer interaction.
Why the inverter needs to dissipate heat
As a power electronic device, the inverter, like all electronic products, faces the challenge of temperature.
In all the failure cases of electronic products, up to 55% of them are caused by temperature.
The electronic components inside the inverter are also very sensitive to temperature. According to the 10-degree rule of reliability theory, from room temperature, every 10 degrees increase in temperature will reduce the service life by half, so the heat dissipation design of the inverter is very important.
Several ways of inverter heat dissipation
The heat dissipation system of the inverter mainly includes materials such as radiator, cooling fan, and thermal grease.
At present, there are two main cooling methods for inverters: one is natural cooling, and the other is forced air cooling.
Pay attention to heat dissipation when installing the system
The inverter itself is a heat source, and all the heat must be emitted in time. It cannot be placed in a closed space, otherwise the temperature will rise higher and higher.
The inverter should be placed in a ventilated space and avoid direct sunlight as much as possible.
When multiple inverters are installed together, in order to avoid mutual influence, there must be enough distance between the inverter and the inverter.
