Big house, two AC’s (5 & 3 ton units). Salt water pool, the pump runs 10hrs/day, every day.
But, I'll suggest that you replace the pool pump with a variable speed one, if you haven't already done so. Even when on the utility, you'll save a bunch of money and pay for it within a year. We replaced our single speed pump with one that runs at half-speed during the daily cycle, and 1/4-speed (about 100 watts) if the temperature drops to near freezing. It only runs at full speed for a minute or so after starting to prime the pump.
I could look at our historical usage (we have a smart meter, with 15-minute intervals) and identify exactly what day the pump was replaced. I also got a rebate from my electric utility, offsetting a substantial part of the replacement cost.
We have a salt cell, as well. But, I don't think it's a significant contributor to the electric bill.
A power management system can be used to be sure that high electrical loads don't all run at the same time: i.e. your two A/C units wouldn't run at the same time, and you could add an electric water header, electric dryer, or electric range/oven to the management system:
