APC is not really the best product, and if it did have a problem like have, at such a small desposable size, your best soluiton is get another one, and a better brand. check out my page that should help you. You overloaded your system and did damage it prior to the fact that now it shows over load all the time. Get a bigger unit.

What can you advice me to do? i have a UPS SURTD5000XLI, indicating a red Led light, but when i remove it from the AC power source, the Red Led also remove & when i flog it again to the AC Source it...

Is red light on for overload or for battery?
If on overload, try reducing the load on the UPS. If red light on overload persists buy a new UPS (overload fault hard to repair).

Red light on battery - replace the batteries.

Red light on boost or buck, may mean that the nominal voltage of ups and the limits need to be changed/corrected.
