4.3 Battery Mode Operation
In the event of a power outage or significant voltage fluctuation, the UPS will automatically switch to battery mode, providing continuous power to connected devices. An audible alarm may sound, and the display will indicate battery operation. The duration of backup power depends on the load connected and the capacity of your external battery bank.
4.4 Overload Protection
The UPS features intelligent overload protection. If the connected load exceeds the UPS's capacity (2100W), it will emit progressive alerts. In severe overload situations, the UPS may automatically shut down to protect itself and connected equipment. Reduce the load by disconnecting non-essential devices if an overload warning occurs.
