DC is not good to use with HPS systems anyway, as DC is always positive on one side, contacts, electrodes etc will burn out much quicker. DC 'shouldn't' work with an AC ballast as the filters 'should' strip away the DC before it gets anywhere useful but that depends on manufacturer. I wouldn't want to try it though
backup battery power by way of a ups for the air pump only!
UPS with a bigger battery will do you fine for the pump
You can go a bit further if you like with a 5KW hybrid inverter with auto mains changeover and 6 kwhrs of deep cycle batteries 😁
