How long can you run a RV AC on Solar? 25C outside 19C inside

How long you can run an AC on solar will greatly depend on what your setup. We have 2 systems in our rv. One system at 12v and one at 24v which is what runs the AC.
The 24v system consists of 1200 watts at 36v into our Victron 100/50 controller which charges our 450AH 24v lifepo4 battery bank which finally runs our 3000watt/9000watt peak sungold inverter/charger

Hello, I enjoyed watching your video, We were able to run (1) AC unit from 12:00 noon on Monday with 100% until 5 pm the next day. We traveled from Los Angeles to Sacramento California. My Victron T70 showed that I had about 11% left on the batteries. I kept the AC unit on during this time period. I have a 3 door residential refrigerator always running and we used the microwave a few times to heat up some food. We didn’t use our generator.
We have a 2008 Fleetwood Expedition 38f class A motorhome
This is our system:
8 12v SOK 206Ah batteries
6 SolarWorld Sunmodule SW 345 XL Mono Solar Panels
3 Victron SmartSolar MPPT 150/70-TR Solar Charge Controller
1 Victron Energy 12V 3000 MultiPlus-II 2 x 120V
1 Victron Cerbo GX MK2 with the Touch 70
I was only able to run one A/C at a time otherwise the inverter would overheat.
If I had a change to do another system I would want a 48v system and 2 inverters running split-phase.
I am happy with the system, however, I will be adding a second Victron Energy 12V 3000 MultiPlus-II 2 x 120V. Or buy two 24V inverters.

Wow that sounds like a great system!
Our system probably would run the second one if I had soft starts installed on them but we are mainly just worried about the bedroom one working for now. As time goes on we will have grid power available so that we don't have to worry about cloudy days. I definitely think that a second inverter would have been a good call for us too but all this stuff starts to get expensive!
