Micro UPS and inverter systems provide power backup systems to field devices. IoT power backups can be categorized into the following categories.
For those devices that do have a primary power source two types of power backup systems are used based on their use case.
|Property||UPS systems||Inverter Systems|
|Functioning mode||Primary power supply comes into a battery storage and battery supplies power to equipment. In case of a power failure micro ups system will prevent equipment from rebooting.||Primary power supply is few directly to IoT equipment without using the battery. In case of a power failure, an ultra-fast switching system switches power source from primary source to a battery. In majority of cases, IoT equipment will not reboot and function as if there was a|
|Battery life||Battery life in UPS based power backup systems is relatively shorter as battery recharge cycles are constantly being consumed even if there is no power failure.||Battery life in inverter based IoT power backup systems is much longer compared to UPS systems as these systems preserve battery charge cycles and use batter only when there is a power failure.|
|Device rebooting||UPS systems should be used in situations where device power backup much also ensure that devices do not reboot using switch over or failure.||Inverter systems should be used where device overall uptime is more important than device rebooting.|
|Device suitability||Internet routers, gateways, NVR / DVR systems for CCTVS||Analog cameras, devices with built-in capacitors, lighting equipment, passive and active sensors in some situations etc|
