It comes down to what you want to keep running during an outage. If you only need the basics—like your refrigerator, lights, and a few outlets—you can get by with a smaller unit. But if you want whole-home coverage, including HVAC, kitchen appliances, and home offices, you’ll need a larger system. Radiant’s electricians will evaluate your household needs and recommend the right size so you don’t end up over- or under-powered.
