Description of this 315KW to 500KW Economical inverter and low price frequency inverter from Powtech
When selecting an Economical inverter, the influence of the environment on the inverter should also be fully considered.
1. Influence of temperature on the inverter: The ambient temperature of the inverter is generally applicable to -10 °C ~ +40 °C. If the ambient temperature is higher than 40 °C, the inverter should be derated by 5% for every 1 °C increase. When the ambient temperature is 10 °C per liter, the life of the inverter is halved, so the problem of ambient temperature and heat dissipation of the inverter must be solved.
2. Influence of humidity on the inverter: The inverter works in an environment where the humidity is below 90%, the relative humidity of the air is ≤90%, and there is no condensation. When the humidity is too high and the humidity changes greatly, the inside of the inverter is prone to condensation, and its insulation performance is greatly reduced, and may even cause a short circuit accident. If necessary, desiccant and heater must be added to the tank.
3. Altitude effect: The inverter can be installed at rated altitude below 1km above sea level. When the altitude is more than 1km, the output power will drop.
4. Influence of dust on the inverter: In the case of metal conductive dust, it is not suitable to install the inverter. The conductive dust will invade the inverter, which will short-circuit the internal circuit of the inverter. In severe cases, the inverter will be burnt. Even non-conductive dust has a great influence on the inverter. In the process of power conversion, the frequency generator generates heat. The general-purpose inverter generally uses forced air cooling to dissipate heat. If there is too much dust in the radiator, it will Affects heat dissipation, resulting in reduced inverter output or failure.
