The KUOYUH 88 series overload protection switch plays a crucial role in desktop uninterruptible power systems (UPS), while the KUOYUH 98 series circuit breaker provides essential protection for MPPT solar inverters.

Here’s a summary of why these protection devices are necessary for each system:

Why Desktop UPS Systems Use Overload Protection Switches (KUOYUH 88 Series)

  • Equipment Protection: Prevents UPS damage by disconnecting power during overloads, and protecting components like the battery and inverter from overheating.
  • Safety: Reduces fire risk, equipment damage, and user injuries by interrupting power during unsafe conditions.
  • Prevention of Electrical Hazards: Minimizes risks like overheating, short circuits, and insulation failure, enhancing user safety.
  • Equipment Longevity: Extends UPS life by reducing stress from excessive currents, preventing costly repairs and replacements.
  • Compliance with Safety Standards: Meets safety regulations for electrical equipment, ensuring reliability and reducing manufacturer liability.

Why MPPT Solar Inverters Use Circuit Breakers (KUOYUH 98 Series)

  • Overcurrent Protection: Disconnects the circuit when the current from solar panels exceeds safe levels, protecting components and wiring.
  • Short Circuit Protection: Prevents high currents from damaging the inverter, panels, or other devices by tripping during short circuits.
  • Fire Safety: Reduces fire hazards by disconnecting power in cases of excessive heating due to overcurrent.
  • Compliance with Safety Standards: Ensures safety and adherence to electrical codes, enhancing system reliability and user safety.

Key Differences Between UPS and Inverter

Key Differences: UPS vs. Inverter

  1. Power Backup:

    UPS: Instant backup with no delay, suitable for sensitive devices.

    Inverter: Provides power by converting DC to AC but has a slight delay.

  2. Switching Time:

    UPS: Virtually zero switching time, ensuring uninterrupted power.

    Inverter: Has a switching delay (500 ms to a few seconds).

  3. Usage:

    UPS: Ideal for sensitive devices like computers.

    Inverter: Suitable for household appliances.

  4. Battery Size:

    UPS: Compact, smaller batteries.

    Inverter: Typically larger batteries.

  5. Cost:

    UPS: Slightly more expensive due to additional features.

    Inverter: Generally more cost-effective.

These protective devices are essential for both types of power systems, ensuring they function safely, reliably, and according to standards.
