Buying Guide: Standby Home Generators At A Glance
What size generator do I need? Start by listing essential loads (HVAC, refrigerators, heating, lighting) and estimate peak demand. Choose a unit that comfortably covers these loads with some margin to handle simultaneous use.
Should I pick natural gas or liquid propane? Natural gas is convenient for grid-connected homes with a steady supply, while propane offers portability and storage but may require higher fuel costs or refueling plans.
What is the role of an automatic transfer switch? The transfer switch detects outages and automatically starts the generator, then transfers power to your home safely. A 100-amp or 200-amp switch is common for whole-house protection.
How important is remote monitoring? WiFi or cellular monitoring helps track performance, maintenance needs, and alerts. Cellular connectivity can add reliability where WiFi is unstable.
What about installation considerations? Outdoor units require weatherproof enclosures, clearances around the unit, and professional electrical connections. Check local codes, permits, and fuel line routing before purchase.
Operational efficiency matters: look for units with managed fuel use, quieter operation options, and warranty support. A 5-year limited warranty is typical for generators in this class and provides long-term protection.
