    This seems like a pointless exercise. You want to charge batteries using an inverter that is being run off batteries. Taking into account the inefficiency of the inverter you would never get the batteries charged to a level near the where the other batteries would be starting from. This is actually a negative process.

    Are you asking whether once mains power is restored, can a UPS inverter be "run backwards" to recharge the batteries? UPS units generally contain battery chargers, but it is not as simple as adding mains power to the AC output terminals of a simple inverter and getting 12V DC out the other terminals.

    What are you trying to design?
