That is how I would do it, but a 120-240 5000w transformer on Amazon was $179. Plug and play.
I am sure a 5 amp buck/boost would cost that. Say you would need 24 volt boost minimum, that is a 100VA unit minimum. Amazon has a 24 volt secondary 250 VA for $145. So yeah, that would be cheaper. Especially if you could find a used one. There is a 32 volt one for 133 but only 100 VA.

BTU to watts you are 1100 watts but the COP of the unit probably is better than 1 so that would be an upper limit. However perhaps 2000 when starting. That amazon unit sounds like it will do the job. Make sure to feed it off of a 20 amp 120 Volt circuit if you can. 15 might work just barely. It will blow with starting if it is gonna blow. -----Original Message----- From: Nate Burke Sent: Wednesday, September 28, 2022 11:00 AM To: af@af.afmug.com Subject: Re: [AFMUG] IceQube Cabinet AC units I looked at the amazon box closer, It can do 5000w, but I think it produces 240 single wire, for European use. Not 120v *2 like US 240v. So it probably won't work.
