Choose this if you need portable backup power on a budget with fuel flexibility. The 13,000-watt portable model offers dual-fuel capability (gasoline and propane), powering home essentials during outages.

A caveat: since it is portable, it requires setup and transfer before use in an outage, making it less automatic than standby systems.

Buying Guide: What To Consider When Selecting A Whole House Generator

  • Power capacity: Match wattage needs to your home’s essential loads. Consider peak and running watts to ensure critical circuits stay powered during outages.
  • Fuel type and availability: Liquid propane, natural gas, or diesel each have pros and cons. Propane and natural gas offer longer-term fuel reliability, while diesel considerations include storage and maintenance.
  • Standby vs. portable: Standby generators start automatically and run on permanent fuel lines, ideal for whole-home protection. Portable units are versatile and generally cheaper, but require manual setup and transfer switches.
  • Installation and permits: Whole-house standbys require professional installation, transfer switches, and compliance with local electrical codes. Always verify permit requirements before purchase.
  • Remote monitoring: Cellular connectivity enables real-time performance alerts and maintenance reminders. Assess whether premium subscriptions are needed for full functionality.
  • Noise and footprint: Higher-wattage models may require more space and produce more noise. Check local noise guidelines and installation clearances.
  • Warranty and service: Review coverage terms and typical service needs. A reliable dealer and nearby service options support long-term reliability.

Additional Buyer Considerations

  • Upgrade paths: If your home expands or loads increase, plan for a model with growth potential or a solution that can be easily upgraded.
  • Maintenance: Standby generators typically require periodic professional maintenance; portable units need routine checks and fuel stabilization.
  • Integration: Ensure compatibility with existing electrical panels and transfer switches. Some units come with integrated transfer switches for simplified installation.

FAQ

  1. What size generator do I need for a typical home? — It depends on your essential loads (refrigeration, heating/cooling, lighting, and outlets). A professional load calculation helps determine the minimum wattage you should cover.
  2. Are cellular monitoring features worth it? — Cellular monitoring provides real-time performance updates and maintenance alerts, which can prevent outages and simplify upkeep for busy households.
  3. Should I choose a portable or a standby system? — Standby systems offer automatic power during outages and require professional installation. Portable units are more economical and flexible but need manual setup and transfer switches.
  4. Can I install a generator myself? — Standby generators require professional installation and adherence to local codes for safety and reliability. Portable units may be installed with proper know-how and safety precautions.
  5. What fuels are safest for home backup power? — Propane and natural gas are common for standby systems due to existing infrastructure. Diesel is another option but requires storage considerations, while gasoline is less ideal for long-term storage.
  6. How long can a generator run during an outage? — Run times depend on fuel capacity and demand. Portable units display run-time estimates; standby models run as long as fuel is available in the tank or connected lines.
