12000 BTU to 16000 BTU?


It’s finally time to replace the 20 year old Marine Air System in my aft cabin. Current system is 12000 BTU... I found a good Dometic replacement that is 16000 BTU (the same size that is in my salon). This aft AC unit also vents into the salon, which on hot days, could use the help. My question is, can my one 30amp panel run this new Ac (per Dometic pulls max 6.6amps) along with my other AC and the AC water pump? The math says it would be fine, but I am wondering if anyone has done this? 12k to 16k... is this overkill? Based on the specs, it should fit nicely under my bed.

Thoughts / Opinions welcome... family doesn’t want to be hot over the 4th. :usa:

Thank you!
