Off grid inverter to take incoming VAC?

I have a cheap Chinese inverter that is off-grid and designed to take solar DC and either converts that to AC or charge a 48 v DC battery (or both at the same time). I'm considering not installing solar panels to connect to this, but i have spare 48 v batteries i want to charge somehow. I could buy an 230 VAC to 48 VDC inverter, but I'm wondering if this off-grid inverter will perform the same function.

Umm, it would depend on the inverter, if it's really off-grid and doesn't have AC input terminals then probably not, if it's an All-In-One then probably. Do you have any more specs than above?

Specs are surprisingly not very informative, but it does show both an AC input from the grid and an AC output.
