Kohler 26RCAL review
Kohler 26RCAL-200SELS 26kW Home Standby Generator with 200-Amp Transfer Switch
By Tom Calder
Kohler's 26RCAL is rated 26 kW on propane and 24 kW on natural gas, with a premium five-year limited warranty. Kohler sells and installs through its dealers, and its manual says the equipment must be installed and serviced by qualified electrical personnel. Check the listing's transfer switch against what your installer specifies before ordering.
- Best for
- A large home that wants a second brand besides Generac at the 26 kW size
- Skip it if
- Your home runs fine on 14 to 18 kW

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- 26 kW on propane, 24 kW on natural gas, per Kohler
- Premium five-year limited warranty
- Sold through a dealer network that handles installation
Worth knowing
- 670 lb, so it needs a pad, gas line and a professional install
- Costs well above the 14 kW and 18 kW sizes

Who shouldn't buy this
Don't buy it if your home runs fine on 14 to 18 kW: the extra capacity adds cost, not much else.
