Non of these will run very long off if the batteries.I understand that. Then you're stuck with a single unit system, and likely with a non-ducted air handler, which wouldn't be the cleanest look in these coaches. 12k would surely be enough to cool the front area but leave the rear air to deal with the bed and bath. I'm trying to think outside of the box and also get away from the roof airs as they are incredibly power hungry. For example, one of my 15k units uses at least 1300 watts while running and struggles to cool down the front section of the coach. A 24k mini split unit uses around 1200 watts while running and is rated for 1500 sqft homes. I plan on expanding my battery bank to about 18kWh and add a couple more 400+ watt panels to the roof. Days that would require AC are generally days with full sun, so power wouldn't be an issue. Quote Selected
Re: Another Mini-Split discussion Reply #26 – March 23, 2023, 04:27:26 pm But wouldn't the 24k unit be 240 Vac so the 1200 watts would be 2400 watts at 120 Vac? Quote Selected

If it is 1200 watts the voltage has already been factored in. Amps at 240 volts would be doubled at 120 volts. Quote Selected 3 Likes

So I taped a box over the door for a week . No problems .How is the overall use of it? Is it able to reach the bedroom? The only place that I don't have a cabinet is in the dining area and that area isn't usable without removing one of the doors of the "bar" cabinet. I'd have to either remove a cabinet somewhere or shove the unit inside of a cabinet and remove a door. Not the prettiest way of doing things. C&H 18,000 BTU Dual Zone 9k+9k Concealed Duct Mini Split with 25ft Kits,... This is still a possibility with one unit under the couch and one unit in the inverter bay with ducts going to the bath and bedroom. If I can get my brain to work well enough, I can duct the under couch unit into the dash ducting to cool the front area.Likely going to go the route of split phase inverter or two inverters running split phase and a sub panel to power the mini-split. Shouldn't be overly complicated. This is a project for later this year or next year, so plenty of time to plan. Quote Selected
Re: Another Mini-Split discussion Reply #30 – March 24, 2023, 06:39:48 pm My bus is not very big inside. It cools well . If it's hot overnight the solar seems to not work as well . So night cooling requires the genset and a fan to blow the air around. To be honest , it's only been required one time . I have 2 computer fans in the bedroom that make a huge difference. Second best improvement after fridge . Quote Selected 4 Likes
