Quick Answer
A suitable generator size for a tiny house typically ranges from 1,000 to 3,000 watts, depending on the household's energy needs, appliances, and desired power redundancy.
Generator Sizing Considerations
When selecting a generator for a tiny house, it’s essential to consider the appliance loads, battery bank capacity, and overall system efficiency. A general rule of thumb is to size the generator 1.5 to 2 times the total appliance load. For example, if the tiny house has a refrigerator (200W), lights (100W), and a laptop (65W), the total appliance load would be 365W. In this case, a 1,000W to 1,500W generator would be a suitable choice.
Portable Generator Sizing Guidelines
Portable generators come in various sizes, typically ranging from 1,000W to 10,000W. For a tiny house, a generator in the 1,000W to 3,000W range is usually sufficient. However, if you plan to run multiple high-power appliances simultaneously, a larger generator may be required. For instance, if you want to run a 1,500W air conditioner, a 3,000W to 5,000W generator would be a better choice.
Important Considerations
When selecting a generator, consider not only the size but also the type of fuel it uses, the noise level, and the weight. A gas-powered generator is generally more powerful and affordable than a propane or battery-powered generator. However, it also produces more noise and emissions. When choosing a generator, make sure to consider your specific needs and the local regulations regarding generator usage.
