@Naglya Put a diode on the wire, so that there is only current flowing from the batteries:

mUPS --------|<------- battery

Thanks for the response, but I need an industrial solution. It is not possible to mount a diode circuit at each connection point.

Hi!
Is there any way to turn off the battery charging
In solar systems, the battery capacity is hundreds of amperes per hour and there is no sense in charging them via mUPS.
