I used an Outback charge controller up on the mountain. Ran perfect.I live off grid in the desert, 2500 sqft house w/4 mini splits. I'm thinking where you are going that doing whole house might not cost much more. Recommend Outback equipment, been running mine 13 years with no failures.
LOL this whole thread is about night only need for cooling - without having to run a gen. The battery bank needs to be big enough to facilitate that ^^, and the panels have to be enough to charge the bank for the next night... rinse repeat.I don't see where you addressed the night only need for cooling, therefore no day time load on the solar....daytime is only charging the storage batteries...
Unless you and PO are just too busy...

I'm currently running four of the FXR3048A inverters in a series parallel configuration. I am also running 5 of their charge controllers, the whole system has been trouble free. The system is 13 years old and I'm looking to get at least another 13 out of it. Where I live a majority of the people living here are off grid and the equipment ranges from ebay Chinese crap on up and no one else has had the trouble free experience that I've had with Outback. If Outback had a poster child, that would be meI used an Outback charge controller up on the mountain. Ran perfect.
How are their inverters? I had two Schneiders fail on me.

48V, running 4- 24V forklift batteries in series/parallel to get 48V at around 2000 Ah+. I ran 3 strings of 8 - 6V golf cart batteries for the first 5 years (their max life) then switched to the forklift batteries. Maintained forklift batteries have a known lifespan of 20 years + in solar use. I went with 24V because they are around 1500# each, 3000# for 48V and my loader maxes out around 1800#. 5 charge controllers because of the Voltage/Current limitations, over 16KW in panels currently. The panels are set up in arrays of 12, four sets in parallel of 3 in series. 3 in series keeps me under the 150V max input, the 4 in parallel keeps me under the max current input. There are more modern ways of doing it now I'm sure, but this works and it's paid for. As an aside I've been hearing of a lot of unhappy people here that are/were running lithium batteries, pack failures, cells swelling, and at least one fire. For the most part rumor and hearsay except for one fellow that works for me who is switching to forklift batteries after his lithium failure.Thanks!
What's your total Ah if I might ask? 13 years old...lead acid? I'm not sure what was available that far back. My little 2nd system (for a primitive chalet) used 2 deepcycle AGMs.
Did you go 24v? 48?
I appreciate your sharing... and I'm still trying to wrap my head around the need for 5 charge controllers..
Your experience is worth more than anything online, imo.
Would someone define mini-split?
It's not really a definition - but think about a window a/c. the cooling part is in the front and sticks out into the room, the compressor hot part is in the back hanging outside. In a 'split' unit (either full sized or mini sized) the front and back parts are separate units; the cooling half is in the house, usually hanging high on a wall, the compressor half sits outside, and they're connected by tubes that goes through the wall.Would someone define mini-split?
I finally looked at the Midea U's - and - those might work pretty well, for a backup A/C now and then later with what I'm tryin to do... thanks again!In your case, 100ah 48v battery, inverter and charge controller (or an all-in-one) using a window air like the Midea U

might be a way to go...

It's on the north end of the east side, all of which is also under a deep covered porch..so it's always in shade except for 1 hr at sunrise. We got lucky that way.Which wall of the house is the bedroom on? If it’s on the north or east side, you might need less cooling capacity / power than if it’s on the west side.
West side of the house gets the afternoon sun, which would make it warmer later in the day going into night. East side should be shaded late afternoon. Same thing with north should be shaded.
Just a thought.
We're going to have a soft start put on the 3ton central A/C... waiting for the guy to call us back, which he will. He's understandably swamped at the moment -How much amperage/ wattage does your air conditioner pull at start up? Might need a soft start.
