Thanks for the info gents. I was hoping to hear much lower numbers. I'm currently sizing for a solar system and the battery storage I need at night is massive due to having some larger sized aircons in the house...
If the bug 48k BTU takes 5kw and I have 15kwat of battery, pretty easy to see that the 3 hours of savings at 5 baht doesn't get me much considering the cost of the batteries.
If it were to drop to 2 to 2.5kwatt, that changes it up a bit..
