EVI Power Line Interactive vs Online UPS: Which Should You Choose?
Choosing between an EVI Power Line Interactive UPS and an EVI Power Online UPS depends on the equipment you want to protect, the level of power protection required, your budget and how critical the connected load is to your operations. Both UPS technologies provide backup power, but they are designed for different environments and risk levels.
Line Interactive UPS systems are commonly used for homes, offices, CCTV systems, POS terminals, routers and general business electronics. Online UPS systems are recommended for servers, network cabinets, telecom equipment, storage systems and critical infrastructure that require continuous power conditioning and higher protection against unstable utility power.

What Is an EVI Power Line Interactive UPS?
An EVI Power Line Interactive UPS provides battery backup and automatic voltage regulation for everyday power protection needs. It helps protect connected equipment from short power interruptions, voltage drops, voltage rises and common electrical disturbances.
Line Interactive UPS systems are suitable for non-critical and moderately sensitive equipment where a short transfer time is acceptable. They are popular for home internet backup, desktop computers, office workstations, CCTV DVRs, NVRs, PoE switches, POS systems and small networking devices.
What Is an EVI Power Online UPS?
An EVI Power Online UPS provides a higher level of power protection using double-conversion technology. In an online UPS, incoming AC power is converted to DC and then converted back to clean AC output power for the connected load.
Because connected equipment receives conditioned output from the UPS inverter, online UPS systems are preferred for sensitive and business-critical equipment such as servers, storage systems, switches, routers, firewalls, telecom systems, medical equipment, data rooms and enterprise infrastructure.
