Backup Generators for Home

A home backup generator is a dedicated power system designed to supply electricity during outages, ensuring that essential appliances, heating/cooling systems, and home electronics continue to function. Depending on the type, it can start automatically when the grid fails or be manually activated to keep your household operational.

When utility power is interrupted, a generator draws fuel from its source—propane, natural gas, diesel, gasoline, or solar—and converts it into electricity. Standby models use an automatic transfer switch to detect the outage and start within seconds. Portable and inverter models require manual setup but can be positioned to supply targeted loads.

Choosing the correct size starts with identifying the wattage requirements of all devices you need to run during an outage. Add together the running watts of appliances, then factor in starting watts for those with electric motors. Oversizing wastes fuel and money, while undersizing risks damaging both the generator and appliances.

Key tasks include regular oil and filter changes, fuel system checks, and monthly load testing. Standby models should be serviced annually by a professional to ensure compliance with manufacturer warranties. Portable units require more frequent inspections if stored for long periods.
