Not really an issue with SLA batteries that UPS use under 10 Kva. If you use a large bank of FLA then you might have issues with ventilation and spill containment, but otherwise no problem. If this is a 10 Kva or smaller unit using SLA batteries put it anywhere you want. You can put in in your living room or kitchen.I'm not sure what the size might be, but at some point you're going to worry about the amount of H2 being generated during recharge.
