FAQ
Can this power my whole house?
Add up your appliances’ running watts with our sizing tool and compare with this model’s rating.
Can I connect a generator to my house?
Only through a transfer switch or interlock kit installed by a licensed electrician. Never backfeed power through a wall outlet.
Can I run a generator indoors or in a garage?
No. Run fuel-powered generators outdoors, at least 20 feet from doors, windows and vents. CO alert shutoff is a safety backup, not permission to run indoors. Battery power stations can be used indoors.

Only CARB-compliant models can be sold in California. Each product page says whether a model is CARB compliant.
How are large generators delivered?
