FAQ
- Question: What is the difference between peak and running watts? Answer: Peak watts are the maximum power the generator can deliver briefly; running watts are the continuous power available for ongoing use.
- Question: Are 15000W inverter generators quiet? Answer: Inverter generators are generally quieter than traditional models, but noise varies by engine size, mufflers, and load.
- Question: Is dual-fuel sufficient for storm outages? Answer: Dual-fuel options provide flexibility, but propane availability and storage should be planned for extended outages.
- Question: Do these generators require professional installation for transfer switches? Answer: Some models are transfer switch ready; installation may require a licensed electrician for safe hookup.
- Question: How do I maintain these generators? Answer: Follow manufacturer maintenance schedules, including oil changes, air filter checks, and spark plug inspections as applicable.
- Question: Can I parallel two units for more power? Answer: Some models support parallel operation; check each unit’s specifications for compatibility and safety.
