Top 5 Home Backup Generator Brands for Power Outages

Written By: MJ Logan

A home backup generator represents a sizeable investment in a major home appliance. The payoff comes when it protects your home and family during a power outage. Food won’t spoil in a refrigerator or freezer, the basement won’t flood, and the pipes won’t freeze. During a heatwave, your home stays comfortable and livable with all the necessities and conveniences of everyday life.

A Single Home with Electrical Power Stands Alone in a Dark Neighborhood Power Outage

Every home is different, and every family has different needs. For some families, powering essentials like refrigeration, sump pumps, heating and cooling, and a few lights during an outage that lasts a day or less is all they require. Other families prefer to supply every circuit in the house. In hot climates, the ability to run multiple air conditioners in triple-digit temperatures is essential.

Home standby generator brands provide similar functionality; all start automatically and switch the house to standby power within moments after the power outage occurs. Later when the utility restores power, the house returns to utility power and the generator shuts down.

Each brand offers specific features and benefits that may matter to some homeowners, but not to others. Weigh the features and choose a manufacturer that offers the right generator for your home and family.
