in paki market, even 3DC acs are marketed as full dc inverter
is that a deal breaker or red flag? in my opinion, No
you can get any 3 or 5dc inverter
yes it's a decent option, my 2022 t3 pro is still doing well, in use 24/7 in summers, in winters. 18 hrs a day
midea xtreme is a decent option too, consider that if T-pro isn't available
knowledgeable sellers? not a single one, research on your own and choose one which suits you the best
