Generac Generators

Generac sells more generators in North America than any other brand, and that scale delivers real advantages: over 10,000 authorized dealers, parts availability that is nearly universal, and pricing that runs 10-15% below Kohler at comparable power ratings. For commercial building owners and property managers who need reliable standby power without paying the CAT or Kohler premium, Generac is the default consideration. Mobile Link remote monitoring comes standard on most units, providing cellular-based status alerts, fault codes, and maintenance reminders through a smartphone app — a feature that competitors often charge extra for.

The honest challenge Generac faces is perception. The brand's dominance at Home Depot and Costco has earned it a "residential brand" reputation among industrial specifiers, and that reputation is not entirely unfair — Generac's warranty claim rates run higher than Kohler and Cummins, with enclosure fit-and-finish and control board reliability being the most common complaint categories. That said, Generac's industrial division is a separate engineering operation producing units up to 3 MW, and those products should not be judged by the residential line's track record.

Where Generac genuinely falls short is power quality and resale value. THD figures sit in the standard 5-8% range, which is fine for most commercial loads but disqualifying for healthcare and sensitive electronics where Kohler's sub-3% is required. Used Generac generators also command significantly less on the secondary market than CAT or Kohler units of the same vintage. For buyers who plan to own for the full 20-30 year useful life and do not need hospital-grade power quality, those gaps are academic — and the 10-15% upfront savings is money in the bank from day one.
