Whole Home Generator vs. Portable Generator: What's Right for You?

Whole Home Generator vs. Portable Generator: What's Right for You?

Wisconsin averages over 40 outage events per county per year. Whether it's a January ice storm or a summer thunderstorm, power outages are a fact of life in SW Wisconsin.

Portable Generators

Portable generators run on gasoline or propane and start manually. They're cheaper upfront ($500–$3,000) but must be stored, fueled, and set up outside. They require a transfer switch for safe whole-home connection.

Standby Generators (Whole Home)

Standby generators are permanently installed, connected to natural gas or propane, and start automatically within seconds of an outage — even when you're away from home.

  • Automatic — no action needed
  • Powers your entire home
  • Runs on natural gas or propane — no refueling
  • Higher cost ($4,000–$15,000+ installed) but much more reliable

The Transfer Switch is Non-Negotiable

Without a proper transfer switch, generator power can backfeed into utility lines — a deadly hazard for utility workers. In Wisconsin, generator wiring requires a licensed electrician and permit.

Installation Cost in Wisconsin

A 22kW whole-home standby generator typically runs $8,000–$15,000 installed in La Crosse. A transfer switch for a portable generator runs $500–$1,500 installed.
