Your set-up is great, frankly. With a whole-house capacity from the Genset, and enough fuel to run as long as needed.
I would never have thought this to be a need, but it’s surprising how unreliable the grid has become, particularly in your area.
I remember an ice storm in Connecticut in about 1976, it took out the roof of the Civic Center, in addition to killing power at my parents house for several days. We got by on Coleman lanterns, and a fire in the fireplace, but eventually the house dropped down to freezing, and my dad was in the process of draining the radiators (hot water heat) to keep the pipes from bursting.
That was a freak event, and no house I’ve owned since has been without power for more than about 48 hours, and that 48 hours was during a hurricane here in Virginia Beach.
Perhaps it’s just me, and perhaps it is anecdotal, but it seems like lengthy. The outages have become more common. And when I start to look at all of the things on which I rely, including refrigeration, and some form of heat and/or air conditioning, the whole house generator starts to become more of a necessity.
