- Diesel: Efficient and lasts a long time, but can be noisy and makes more pollution. Diesel generators are often chosen because they’re tough and use less fuel, making them good for long-term or frequent use.
Power Output and Sizing Considerations
When it comes to generator size, bigger isn’t always better. Choosing the right size generator makes sure it works well and doesn’t waste fuel. It’s important to balance your power needs with the generator’s size to avoid overloading or using too little of its power.
Here’s a simple guide for home generator sizing:
- 5,000-7,500 watts: Good for powering main appliances in a small to medium-sized home. This size can run a fridge, some lights, a sump pump, and a few small appliances.
- 7,500-10,000 watts: Good for a medium to large home with normal power needs. This size can handle most household appliances, including a well pump or central air conditioning.
- 10,000-15,000 watts: Can handle most large homes with several big appliances. This size is good for homes with electric heating or those needing to run several major appliances at once.
- 15,000+ watts: Best for very large homes or those with special power needs. This size works for homes with big electrical systems, multiple HVAC units, or special equipment.
Remember to think about both running watts and starting watts when sizing your generator. It’s also a good idea to add about 20% to what you think you need for future growth. This extra power allows for adding new appliances or using more power over time without needing to upgrade your generator right away.
Installation and Safety Considerations
Proper installation and safety measures are very important when setting up a home generator. Making sure it’s installed correctly not only helps the generator work better but also keeps your home and family safe from possible dangers. Here are some key things to remember:
