Quick Answer
To determine the right generator size for doubling output, divide the total power required by two, then add 10-20% for safety and efficiency. This ensures both generators can handle the load without overloading. Consider the type of appliances and their power requirements.
Understanding Generator Sizing
When sizing generators for parallel operation, it’s essential to consider the total power required to meet the load. A common mistake is to simply double the size of the individual generators. However, this can lead to overloading and reduced efficiency. A more accurate approach is to calculate the total power required and divide it by two, then add 10-20% to account for safety and efficiency.
Calculating Generator Size
For example, if you need to power a 2,000-watt refrigerator, a 2,000-watt air conditioner, and a few lights, the total power required would be approximately 3,500 watts. To double the output, divide 3,500 watts by two, which equals 1,750 watts. Add 10-20% for safety and efficiency, resulting in a generator size of 1,925-2,100 watts.
Selecting a Generator Parallel Kit
When selecting a generator parallel kit, look for a kit that can handle the total power required. A common parallel kit configuration is a pair of generators with a combined output of 2,400-4,800 watts. Ensure the kit includes all necessary components, such as a control panel, transfer switch, and wiring harness. Also, consider the type of generators and their compatibility with the parallel kit. Some generators may require specific adapters or modifications to operate in parallel. Always consult the manufacturer’s instructions and recommendations for parallel operation.
