Advantages of line interactive UPS:
- High reliability
- High efficiency
- Reasonable voltage conditioning
- Lower component count
- Rugged design
- Lower operating temperature
- Lower electricity consumption
Disadvantages of line interactive UPS:
- Impractical over 5KVA
- It requires frequent battery use in areas of the extreme voltage of distortion
- Do not provide power factor correction or frequency regulation
