I have been a subscriber to this channel for several years. Long story short I had extensive electronics training in the USAF in the 1960s and spent about 20 years working on computers (Main frame and PCs) before buying a PC and Networking company which I retired from in 2011. Over the last couple years I computerized my wife's quilting machine and built a 48" x 36" CNC router for my woodworking shop. My current project is insulation my workshop so I can install a mini-split system to heat and cool it year around.
@dave41 Welcome to the forum. Sounds like you have some experience. Are you considering solar power for the mini split? Victron has some inverters that can power a mini split with some battery power, and some grid. When I had my RV and it was plugged into a 30A connection, I could if needed draw a total of 50A. There are a lot of details and if anyone is interested I will be happy to share, but it's not difficult.
