What Home Backup Actually Requires

Home backup has three non-negotiable requirements: sufficient surge capacity to start your largest appliance, enough runtime for your outage duration, and ideally UPS mode for sensitive electronics.

Refrigerator: 150W average, 1,200W surge. Any generator with 1,800W+ surge covers it. 1,800Wh capacity = 12 hours runtime.

Well pump (½ HP): 500W average, 2,600W surge. Requires a generator with at least 3,000W surge. The DELTA 3 Max at 4,800W covers this.

Window AC: 800W average, 2,200W surge. Any mid-range generator covers it. Runtime is the limiting factor — 1,800Wh gives approximately 2.25 hours of continuous AC.
