THE 30-SECOND ANSWER

For home backup, prioritize 120/240V output, enough running watts for the loads you actually plan to carry, CO safety features, and a safe transfer setup. Tri-fuel models are especially attractive if natural gas is available at the house.

DON’T OVERBUY

Do not buy wattage you cannot safely connect.

A giant generator does not help if the transfer equipment, inlet, extension cords or fuel supply are wrong. Size the system around real loads and use a qualified electrician for transfer equipment.
