Advantages And Disadvantages Of hot Backup In Series Connection Between Master And Slave

Uninterruptible Power Supply(UPS) Advantages:

1. Two or even more UPS are basically in a relatively independent and non-interfering operating state.

2. The requirements for UPS synchronization tracking performance are relatively low.

3. Use UPS of different models and capacities to form a series hot backup method.

Disadvantages:

1. The slave is in a no-load operation state for a long time and has low efficiency.

2. The slave battery pack is in a floating charge state for a long time, and there are few opportunities for regular load discharge maintenance, which will affect the battery life.

3. The slave must have a good step load capacity.

4. For long-term operation, the host inverter = static bypass conversion function is good and there is no expansion function.

5. Compared with the "parallel" redundant system, the average failure-free time is relatively low.
