Buying Guide: Key Considerations For Gas Generators
- Power needs: Match peak watts to start-up requirements of devices and running watts to continuous loads.
- Fuel capacity and runtime: Larger tanks extend runtime but add weight; consider expected load duration.
- Portability: Weight, handle design, and wheeled frames affect how easy it is to move the unit.
- Noise level: Inverter generators typically run quieter and are safer for sensitive electronics.
- Outlets and compatibility: Check available outlets (120V, RV, and 12V DC) to fit your devices.
- Fuel availability and efficiency: 2-stroke vs 4-stroke engines impact maintenance and efficiency.
- EPA/CARB compliance: Ensure local regulatory compliance if used in restricted areas.
- Safety features: Look for automatic low-oil shutdown and overload protection for protection and reliability.
Frequently Asked Questions
- What size generator do I need for home backup? — Choose based on essential loads; common options range from 1000W to 5000W for basic essentials, up to 12500W for more comprehensive backup.
- Are inverter generators quieter than traditional ones? — Yes, inverter generators typically produce less noise and cleaner power suitable for electronics.
- What is running watts versus peak watts? — Running watts cover continuous load; peak watts cover short surges for starting devices.
- Can I run a large appliance like a refrigerator on a 1600W generator? — It may be possible with surge considerations, but verify the refrigerator’s starting wattage and the generator’s peak watt capability.
- How long will a typical generator run on a full tank? — Runtime depends on load and tank capacity; many models offer several hours at light loads and fewer at heavy loads.
- Do I need a permit or transfer switch for home backup? — Some jurisdictions and home setups require transfer switches for safe connection to home circuits; check local codes.
