Don't want to start a firestorm here, but I ran into some information stating one could operate typical air conditioning system in a TT from the batteries through an inverter when off the grid. So just wanted to get some feedback from the good folks here.
A/C would be 13.5 K and the inverter would be a 3,000 watt (minimum). I think, if I calculated correctly, that's about 25A per hour, and with inverter power loss ~28A per hour. Correct me if this is incorrect please.
Believe it or not, I can't locate the electric service spec on the Outdoors RV I'm interested in, so I don't know if it's 30Amp or 50Amp. If I have a choice, I'm going with the 50. A dealer I talked with last week was supposed to get back to me, but hasn't. Imagine that!
More info, the rest of the dreamed-of system would be solar panels with a lithium battery bank of ~600Ah and an inverter/charge combo. Now I'm not talking about running the A/C even most of the day. I'm looking perhaps to have the capability to use A/C maybe 1 to 3 hours if necessary just to cool things off late in the day for example. The times of year and places I plan to be will be temperate, with nights down into the 50s and day highs in 80s. BUT we all know weather, and know that excursions above or below our expectations can happen before one can get outa Dodge. Also, my metabolism is pretty low, so I don't need things as cool as some of you "hot bodes" most likely do (LOL)
Also plan to have a Honda 2000 W generator. I know I could add the companion Honda 2000W to that and run the A/C from generator, but I REALLY don't want the noise and the hassle of dong so. Generator would be mounted in the truck bed. Clouds, rain, dirt and or tree shade on panels are probable at times.
So far, my estimates of daily power consumption (since I've not lived in the TT yet) EXCLUDING A/C, looks to be about 215 Ah -- I like TV and will run fans to cool TT interior overnight. Some of you may indicate that I'm doing overkill on the lithium battery, and that might be true, but all this is still very much in the planning stages so may change. If practicable and useful to add on more battery or panels later (even portable type), I may start with a smaller system.
So can one operate a 13.5K A/C from the 12V battery bank though an appropriately-sized inverter? -- Assuming one is prepared to deal with battery charge and discharge rates of about 28A per hr, and not planning to operate A/C over 3 hours/day or so when off grid.
Your thoughts please.
