Quick Answer
A 2-3 kW diesel generator is ideal for tiny homes, as it provides sufficient power for essential appliances and lighting while minimizing fuel consumption and noise pollution.
Choosing the Right Generator Size
When selecting a diesel generator for a tiny home, it’s essential to consider the total power requirements of the appliances and devices that will be running simultaneously. A general rule of thumb is to add up the wattage of each appliance and multiply by a factor of 1.5 to 2 to account for startup surges and other inefficiencies. For a typical tiny home, this translates to a generator size of 2-3 kW.
Calculating Power Requirements
To calculate the power requirements of your tiny home, make a list of the appliances and devices that will be running simultaneously, along with their respective wattage ratings. For example:
- Refrigerator: 150 watts
- Lighting (4 LED bulbs): 60 watts
- Laptop and phone charging: 60 watts
- Small water pump: 100 watts
Total power requirement: 370 watts
Multiply by a factor of 1.5 to account for startup surges and inefficiencies: 370 x 1.5 = 555 watts. Since generators are often rated in kilowatts (kW), convert the total power requirement to kW: 555 watts / 1000 = 0.555 kW or 0.55 kW. Round up to the nearest whole number, as generators are typically sold in whole kW increments.
Selecting a Suitable Generator
Based on the calculated power requirement, a 2-3 kW diesel generator would be suitable for a tiny home. However, it’s essential to consider other factors such as fuel efficiency, noise level, and maintenance requirements when selecting a generator. Look for a generator with a high fuel efficiency rating and a low noise level to minimize disruptions and save on fuel costs. Additionally, consider the size and weight of the generator, as well as its compatibility with your tiny home’s electrical system.
