Do not place the power supply on uneven or inclined surfaces. Avoid direct sunlight, rain, or damp conditions. Keep away from fire sources and high-temperature environments to prevent damage due to excessive heat. Be cautious of oil mist, salt corrosion, and prevent dust, cotton fibers, and fine metal particles from entering. Place the inverter in a well-ventilated area, ensuring the back is at least 10 centimeters away from the wall to maintain proper ventilation of the intake holes. The operating environment temperature should be maintained between 0 to 40 degrees Celsius, with humidity between 0 to 90%. Do not place it in areas with corrosive gases.
Regular maintenance can also ensure a longer lifespan for the power supply. Pay attention to cleaning the air filter cooling ducts and internal dust. Inspect screws, bolts, and plug-in connectors for tightness; there should be no looseness. The input/output reactors' ground and phase resistances should not have short circuits, and conductors and insulators should be cleaned with alcohol. If conditions permit, also check the stability of each switch voltage to ensure circuit waveforms do not distort, etc.
Establish a schedule for regular power supply inspections, aiming for at least once a year. Each product is composed of numerous components, and due to prolonged operation, some components may degrade in performance, leading to aging and wear. Therefore, we often need to replace certain parts to ensure proper functioning. The main components requiring replacement are filter capacitors and cooling fans. Filter capacitors typically have a lifespan of around five years, primarily used to smooth out DC voltage, directly affecting the capacity. Cooling fans usually last between two to three years. As critical components in the power supply that dissipate excessive heat, their role is to expel heat promptly to prevent damage to parts and significant wear.
In summary, proper maintenance and care for power sources during the summer can ensure their safe use and minimize losses caused by power source damage.
