Buying Guide: Key Purchase Considerations
What size is appropriate for my home? Match generator wattage to anticipated load, including HVAC, refrigeration, and lighting. Larger homes often need 14kW to 26kW units, while smaller homes may be well served by 10kW models.
Do I need a transfer switch? Yes for most whole-house setups. A 100 Amp or 200 Amp transfer switch ensures seamless automatic power transfer and supports nice integration with modern panels.
Is remote monitoring worth it? Cellular or Wi-Fi monitoring helps you receive maintenance alerts and performance updates, aiding proactive servicing and quick response during outages.
What about fuel type and availability? Dual-fuel options offer flexibility but require fuel source availability and proper outdoor venting for safety and performance.
What about installation and warranty? Professional installation is advised for permanent standby units, especially with electrical and gas connections. A 5-Year Limited Warranty or longer is typical for many Generac models and provides long-term protection.
