Not everything turns on or surges at the same time. Its just not as big a deal as some make it out to be.
Mitch, 12a shocks me on the water heater. (edit: Yep, 1400w/120 = 11.6...most inefficient thing on there.)
"inefficient" resistance heat uses 99.9% of the energy.
Where one needs to worry is motor operated devices such as the horribly inefficient roof air conditioners. Below 107 volts there is ongoing cumulative permanent damage to the device.
If I'm in that situation I connect the autoformer. I've used it at an input voltage of 97 on a 15 amp circuit successfully. I did have to move the fridge to propane there were no other 120 volt loads except for the inverter charger. The house batteries were fully charged.
I do limit energy input to 24 amps using the inverter/charger and often have the load support feature active.
The largest load is the microwave at 1570 watts. I don't "cook" in it but do thaw home made meals. 222 seconds and my knife and fork are active.
