When it comes to ensuring uninterrupted power supply in a 1,200 square foot home, selecting the right generator size is crucial. The right generator not only keeps your household running smoothly during outages but also safeguards your appliances and electronic devices. This article provides a detailed guide on determining the appropriate generator size for your home, the types of generators available, and the factors influencing your decision.
Understanding Power Needs
Identifying Essential Appliances
Before choosing a generator, it’s essential to identify which appliances and systems in your home require backup power. Common household items include:
Refrigerators: To keep food from spoiling.
Heating and Cooling Systems: HVAC systems require substantial power.
Lighting: Essential for safety and security.
Electronics: TVs, computers, and Wi-Fi routers.
Water Pumps: Important if you have a well or sump pump.
Calculating Total Wattage
Once you have identified your essential appliances, the next step is to calculate the total wattage required. Each appliance has a wattage rating, usually found on its label or in the user manual. To calculate the total wattage:
List all essential appliances.
Note their running watts and starting watts (some appliances require more power to start).
Use the formula:
Total Wattage=Sum of Running Watts+Sum of Starting Watts

Starting vs. Running Watts
Understanding the difference between starting and running watts is crucial:
Running Watts: The continuous power required to keep an appliance operating.
Starting Watts: The extra power needed to start an appliance, which may be two to three times higher than the running wattage.
When calculating your generator size, always consider the starting wattage, especially for motors (like refrigerators and air conditioners).
Types of Generators
Portable Generators
Portable generators are versatile and typically less expensive than standby generators. They can power essential appliances and are ideal for temporary outages. However, they require manual setup and fuel management.
Standby Generators
Standby generators are permanently installed outside your home. They automatically activate during a power outage, providing seamless backup power. These generators are typically powered by natural gas or propane and offer higher wattage capacity, suitable for powering multiple appliances simultaneously.
Inverter Generators
Inverter generators produce clean, stable energy and are quieter than traditional generators. They are excellent for sensitive electronics but usually provide less power than standby generators. Inverter generators can be portable or fixed, depending on your needs.
Factors Influencing Generator Size
Peak Load Requirements
Understanding peak load requirements is essential in determining the right generator size. If you plan to run multiple appliances simultaneously, ensure that your generator can handle the total wattage.
Duration of Power Outages
Consider how long you typically experience power outages. If outages last for extended periods, investing in a larger generator may be necessary to keep all essential systems running.
Fuel Type Considerations
The type of fuel used can affect the generator’s overall efficiency and operational cost. Common fuel types include:
Gasoline: Readily available but not as efficient for long-term use.
Propane: Offers longer shelf life and cleaner burn.
Natural Gas: Convenient for standby generators but may require additional installation considerations.
Selecting the Right Size Generator
General Sizing Guidelines
A good rule of thumb for residential generators is to allow for a buffer above your total calculated wattage. Generally, you should add 20% more wattage to account for unexpected loads.
Recommended Generator Sizes for a 1,200 Sq Ft Home
For a 1,200 sq ft house, the following generator sizes are recommended based on common household needs:
Small Appliances Only: For basic needs (lights, refrigerator, and one or two small appliances) — 3,000 to 5,000 watts.
Moderate Needs: For medium power needs (heating/cooling systems, multiple appliances) — 5,000 to 7,500 watts.
Full Home Backup: For full backup (all appliances, HVAC systems) — 7,500 to 10,000 watts.
Consider your specific requirements when choosing the generator size.
Installation and Maintenance Tips
Professional vs. DIY Installation
For standby generators, professional installation is recommended. This ensures that the generator is correctly connected to your home’s electrical system and complies with local codes.
Regular Maintenance Practices
To ensure optimal performance and longevity, follow these maintenance tips:
Regularly change the oil and air filters.
Inspect fuel lines and connections for leaks.
Run the generator periodically to keep it in good working condition.
Conclusion
Selecting the right generator for your 1,200 square foot home involves careful consideration of your power needs, the types of generators available, and specific factors that influence size. Whether you opt for a portable, standby, or inverter generator, understanding your wattage requirements and installation options is key to ensuring a reliable power supply during outages. By following the guidelines outlined in this article, you can confidently choose a generator that meets your household needs and keeps your home running smoothly.
