In order to ensure that this family member can serve us healthily and for a long time, it is crucial to choose a suitable working environment, just like creating a cozy home for it.

Temperature is the first element that needs to be carefully taken care of in this home. The inverter is like a sensitive artist, with a delicate sense of temperature change. Too high or too low a temperature will adversely affect its “mood” and “health.” Therefore, we need to choose a suitable temperature for it, the four seasons like spring “residence,” to ensure that it operates at the optimal working temperature, neither feeling “unbearable heat” nor suffering “cold attack.”

Humidity, on the other hand, is another key to balance in this home. The sophisticated components inside the inverter, like delicate babies, have strict requirements for humidity. Excessive humidity is like putting heavy wet clothes on the baby, which will make them feel uncomfortable and even cause “disease.” Therefore, we need to keep the humidity of the working environment moderate, to create a dry, comfortable environment for the inverter so that it can work at ease.

Dust and debris are the “uninvited guests” that need to be alerted in this home. They are like cunning thieves who take the opportunity to sneak into the inverter’s interior and steal its “health” and “vitality.” Therefore, we need to clean up the dust and debris in the working environment regularly to build a solid defense for the inverter, ensuring that its heat dissipation effect and performance stability will not be affected.
