My inverter has a/c in terminals. When it sees power on these terminals it feeds the power through plus siphons some off to charge batteries. If you were to copy my set-up you could get one of those water heater timers to turn the a/c in on at night. Use the cheap golf cart batteries since you will be recharging both day and night. On cloudy days your batteries will be more seriously depleted and you will draw more grid power at night. In SHTF situations you will already be in off-grid mode and can either conserve power to make do with solar PV recharging or you can plug into a generator.
Not saying it would be cheap to install the system I describe. You need to value having a whole-house UPS/off-grid capability to make it worthwhile.
