I have 41 years exp in hvac and have installed quite a few mini splits including several with multi indoor units matched with a single outdoor unit.
I believe that the mini split could be adapted for an RV although I have not seen that application before.
The amperage draw for the cooling attained with the “inverter” style mini splits is very low and most act as heat pumps to provide heat in winter. I would recommend a good generator sized for it...I don’t know enough about solar power arrays to advise.
A couple of things...don’t buy a system off the internet. Contact a local HVAC wholesaler and price them. Warranty parts for systems bought on the net are sometimes impossible to acquire.
Don’t buy one of Chinese mfg...use Japanese or Korean.
i will second dont use chinese mini splits
crap no spare parts and expensive if you need them and can get them
Thanks for the info and advise. Mini splits are apparently common in RV's in Australia and Europe but have yet to catch on here for whatever reason. They're regarded as well-suited for solar by people who know, one of whom I'm not but I'm working on it. The size of the solar array for any sort of A/C is a challenge for RV application though, as I understand it thus far/
By the way, I was under the impression that this Senville unit that caught my eye was Japanese for some reason, it has at least one Toshiba component in it.
