Buying Guide: Key Purchase Considerations
- What is my home’s load requirement? Determine total running watts needed for essential circuits and appliances to avoid overloads.
- Fuel options: Do you prefer gasoline, propane, natural gas, or a combination? Tri-fuel options offer flexibility during fuel shortages or storage considerations.
- Portability vs. standby: Portable models require manual startup and fuel management, while standby generators offer automatic transfer and remote monitoring.
- Transfer switch compatibility: For automatic house-wide backup, ensure you have a compatible transfer switch and electrical integration plan.
- Ventilation and space: Outdoor placement requires weatherproof enclosures and clearance for safe exhaust and maintenance access.
- Maintenance and monitoring: Look for models with monitoring features, CO detectors, and straightforward maintenance intervals.
