i have a battery bank cupboard and i wanted to put the inverter in there but the batterys give off gases and the inverter is electrics is it safe to pu them in there
It would be safe, BUT you must remove the heat generated in that room, preferred method would be forced air. drilling a few holes about 6-8 inches below and door opening and above the floor and then placing a vent register such as used for heating in a home would help to dissipate the heat much quicker than straight force air.
Even if the batteries are sealed lead-acid, it will have to be forced-air ventilated or your inverter will cook to death.
