@impulse it’s rather difficult to know much with little data, for example what was your desired humidity level, what was the starting level, what was the cubic capacity of the room, how well sealed is it, etc, etc.
in my case I have a 47l/day unit the room capacity is around 18,000 ft3 the temperature will be around 27C~30C, the required humidity under 70% and the outside humidity at about 35C is over 80%
My unit can drop the humidity enough, running for about 10 hours overnight so it isn’t usually needed during the day.
So dry enough for my needs. If you want sub 50% and sub 25C then you would need double or considerably more.
if you are buying an inverter, many are today, then well over capacity doesn’t hurt and it will probably be quieter.
