Hi, congrats on the purchase.
- will your AC start on 15A service? - Most likely not although not impossible, I wouldn't try to do it. 15,000 BTU A/C will need about 13-15A to just run and about 22-25A to start. If the breaker on your campsite is oversized it may allow for it but even then just running A/C will be already bringing that infrastructure to stress. When pushing electrical components they get hot, start to pose fire risk & short risk. Also, keep in mind that's only A/C. You will have also your converter charging your batteries after the slides were extended (typically up to 6A), lights, radio, TV, your electronics charging - all that also adds up. If your RV has 50A service I'd say you have 99.9% guarantee it won't start.
- Solar panels provide 12V, A/C takes 110V - unless you have installed an inverter they will make no difference. Solar panels are good to keep the batteries charged, if installed on the roof they also slightly limit the amount of heat absorbed by the RV.
- The only way to run A/C on propane is to have generator that runs on propane. A/C runs on electricity only.
TIP: If you decide to go the generator route you can either buy one that is 3000-4000W range or two smaller ones (1500-2200W range), connect them in parallel to start your A/C and run only one of them afterwards. Most generator manufacturers sell now proper adapters to do that. Smaller generator takes much less fuel.
TIP2: If you decide to go the generator route most parks have limited hours when these can be run.
