Online UPS connects the computer directly to the battery backup at all times. The UPS will be designed to power certain equipment, such as a personal computer, without any objectionable dip or brownout to that device. The switch-over time can be as long as 25 milliseconds depending on the amount of time it takes the standby UPS to detect the lost utility voltage.
Offline UPS connects the computer to the ESKOM's power grid (or to a generator) until the voltage falls below a certain level, in which case, the UPS switches over to battery backup.
You will need to switch over to a generator or power your PC down.Īn inverter is meant for continuous power and will not beep continuously.
