Electric Generator Size Calculator
Based on the information provided in the search results, I’ve created a comprehensive table summarizing the key considerations for electric generator sizing. This table covers all you need to know when selecting an appropriate generator size for your needs.
| Feature/Consideration | Description |
|---|---|
| Assess Power Needs | Determine what appliances and systems you want to power during an outage. |
| Surge vs Running Wattage | Consider both the starting/surge wattage and the continuous running wattage of devices. |
| Appliance Types | Different appliances have varying wattage requirements, especially motors. |
| Site Conditions | Elevation and ambient temperature can affect performance and size requirements. |
| Fuel Type Options | Options include diesel, gasoline, propane, and renewable energy sources. |
| Portability | Consider if you need a portable generator or a stationary one. |
| Generator Type | Choose from inverter, portable, or standby generators based on usage. |
| Safety Features | Look for safety features like circuit breakers and automatic shut-off systems. |
| Efficiency Ratings | Higher efficiency can lead to lower operational costs over time. |
| Noise Levels | Noise levels vary significantly; check local regulations and requirements. |
| Home Size | Small homes: 5,000-7,000 watts; Larger homes: 8,000-15,000+ watts1. |
| Load Management | Some generators have systems to prioritize essential loads1. |
| Environmental Impact | Consider eco-friendly options and emission reduction technologies1. |
| Future Needs | Anticipate potential increases in power requirements1. |
| Conversion (kW to kVA) | Use power factor (typically 0.8) to convert between kW and kVA3. |
| Running Requirements | For primary power, size for 70-80% capacity; leave 20-30% safety margin3. |
| Site Access | Consider delivery and installation constraints when sizing3. |
| Home Square Footage | Rule of thumb: 1000 watts per 100 square feet of space4. |
| Sensitive Electronics | Consider inverter generators for powering modern electronics4. |
| Professional Consultation | Consult with a certified electrician or generator specialist for accurate sizing34. |
This table provides a comprehensive overview of the factors to consider when determining the appropriate size for an electric generator. It covers various aspects from power needs assessment to environmental considerations, ensuring you have all the necessary information to make an informed decision about generator sizing.
