I have 2925W of solar and 22.8kWh of LiFePO4, listed in my signature. Inverter wise, I have two Victron 3kVA inverters running in split phase and a couple Autotransformers to load balance the 120V loads across the pair of them and to ensure that all single phase input (Onan generator, 30A shore power, etc) is stepped up to 240V split phase before being fed in. End result is I have 240V split phase power available at all times, whether from shore, generator, battery, or solar.
With the amount of solar and battery I've been able to keep the entire rig 70F on 95F days in Arizona without gen/shore and I've been able to keep it the same 70F on 40F days with below freezing nights in Idaho. Much above 95F and I'll still have to run the generator a small bit, so I'm eventually going to move to an elevated rack and add another 975W of panels. Those metrics also include virtually "normal" electrical use in the rig, including running the convection oven for dinner, blender, TVs, etc. We don't really do much to conserve, as we designed the system not to require it.
Even with this amount of solar/battery, using the rooftop ACs in this manner is entirely out of the question. On a 95F day they would use around 45kW. Our panels will produce 15-20kW on most days, and our battery capacity is only 22.8kWh. The split units use approximately a third of the power.
