    Tips: Service Life of Components of Power Inverter

    Inverter belongs to switching power supply in a broad sense, so its components can be basically divided into resistors, capacitors, diodes, power devices (IGBT or MOS), inductors and transformers, current sensors, IC, optocouplers, relays and so on.

    The service life of resistors, patch capacitors and ceramic capacitors can generally reach more than 20 years. When designing inductors and transformers, as long as they do not exceed the material temperature, they are theoretically considered to be able to work for a long time without failure; low-power diodes, transistors can basically work for more than 100,000 hours; for relays, their mechanical life is basically more than 1,000,000 times and electrical life is more than 10,000 times. As long as the design specifications are met, the life of power device IGBT or MOS is generally not considered. Fans and fuses of power inverters are vulnerable components, which will not affect the life of the inverters, but can be replaced in time if they are damaged. The service life of thin film capacitors is more than 100,000 hours; the lifespan of electrolytic capacitors is generally 2000-3000 hour at 105℃, and the longer one is only 5000-6000 hours, but with the temperature decreasing by 10℃, the lifespan turns over. Times. So in the power inverters, the shortest part of the device is the life of the electrolytic capacitor.

    3000 watt inverter charger works perfectly
    I’ve had this 3000 watt inverter charger for several days now, and so far it seems to be working as described. It ran my laptop perfectly fine for several hours on vehicle power. I will order more.

    3000 watt inverter charger
    I am looking at the 3000 watt inverter charger. I would like it with network connectivity. Is that possible? To hook it up to an ethernet switch and access it via network.

    Unfortunately, the inverter charger cannot be connected to an ethernet switch, and no network communication, but we can provide remote control with cable (5m).
    Good inverter charger, very efficient.
    I have got this 3000W inverter charger three weeks ago. It is very convenient to use that works well for 24V DC to 240V AC and recharges the battery bank. And the LCD display is good to know the working status. This pure sine wave inverter has high surge power up to 9000 watts, allowing it to run appropriately for my compressor. Good inverter charger, very efficient.
