We were out of power for 5.5 days... The longest outage in 24 years. Our power line from road was down. Power was restored at the road, but the storm took out a lot of customers, so we were among the last to be restored. Used a Honda 3000I to power TV, computer, internet, lights, refrigerator & freezer. Most of the time the Honda was part load, so the hum wasn't noticeable.
Originally bought the Honda for camping at horse events. Noise is critical there. The Honda is expensive but quiet.
The Honda inverter produces clean power suitable for delicate electronics like the TV. The Generac 4000 is noisy, produces dirty power but also produces 240 volts. The Honda doesn't. Need it for the well pump.
This is a "good what if " exercise for everybody on the forum. Consider what one does for cooking, heating, cooling, communication, entertainment, drinking, civil unrest, etc. Can one get out to the main road if driveway is blocked by downed trees, snow drifts, flood water etc. Power outages used to be rare. Seems the power grid is more fragile these days. And we're more dependent on electricity.
