agreed, but generator power = expensive power, even with nat gas. In spite of my avatar name, I do maintain a grid supply connection, November - Early January are tough to deal with in my neck of the woods, the choices are: over-panel x3.5 of my summer needs, or pay to run the expensive generator power, or keep the utility connection, or do without some energy uses for 2.5 months (and my spouse leave me!).
For us, we used to have two utility services, now only one -our business is located next door and is 100% off grid, the house became the summer 'dump load' as a result of exess energy available. Now we are increasing the capcity of the total system and using an EV as the main dump load.
To your point: we use solar first, then battery, then utility, and lastly the generator (if the others are all unavailable) four levels of power supply. The cost for maintaining the utility service, with minimum monthly charges etc is still a lot less then running a generator, and quieter too.
