Cold start performance: How do brands compare for propane generators?

Generator Ratings and Cold Start Performance

When it comes to propane generators, cold start performance is crucial for reliable operation in cold weather. The American Society for Testing and Materials (ASTM) has a standard testing procedure for cold start performance, which involves starting the generator at -20°F (-29°C). Generator manufacturers often publish their cold start performance data, which can be a useful guide when shopping for a new propane generator.

Brands and Cold Start Performance

Brands such as Generac and Cummins Onan are known for their high-performance propane generators that can start and run reliably in cold conditions. For example, the Generac GP15000i can start and run at -22°F (-30°C), while the Cummins Onan MDKBT can start at -20°F (-29°C) and run at -10°F (-23°C). Other brands, such as Westinghouse and Champion, may not perform as well in extreme cold conditions, with some models struggling to start at temperatures below 0°F (-18°C).

Key Features for Cold Start Performance

There are several key features that contribute to a propane generator’s cold start performance, including the type and quality of the engine, the propane valve and regulator, and the ignition system. Generators with high-quality engines and advanced ignition systems tend to perform better in cold conditions. Additionally, generators with features such as automatic cold start and remote start can make it easier to start the generator in cold weather.
