How to Choose an Online UPS
Size real load
Use watts and future headroom, not only the VA number on the label.
Plan runtime
Battery modules matter when shutdown time or generator start is required.
Check format
Rack, tower and convertible units must fit the room or cabinet.
Add monitoring
SNMP or USB management helps prevent silent battery and overload issues.
