Best Home Standby Generators for Hot Climates
Liquid cooled generators operate more efficiently in hot weather. Their cooling system is similar to that found in cars and trucks. The engine pumps a liquid coolant through the engine to absorb heat and returns it to a radiator. The engine fan blows air through the radiator to cool the liquid inside. Even in hot temperatures of 120 o Fahrenheit and beyond, the system efficiently removes heat from the engine allowing it to run for hours or days as required.
Generators de-rate their power above a certain temperature and altitude. This means a 20-kilowatt standby generator loses 1000 watts of power when temperatures rise above 110 degrees. Altitude causes even more power loss. Standby generators without liquid cooling that run on natural gas usually have a lower power capacity than propane.
An air cooled generator uses a fan to blow air directly over the engine to remove heat. It is a simpler design and efficient in moderate climates, but overheat in hot weather.
A liquid cooled generator provides the same power on natural gas or propane. High altitude, high ambient temperatures, or combinations of those factors can mean a significant power decrease for air cooled units. A higher rated liquid cooled generator won’t lose as much power and can operate just as efficiently on natural gas.
Air-Cooled vs Liquid Cooled Generator—Why it Makes a Difference
Generac Power Systems manufactures their line of Protector and Commercial series liquid-cooled generators. Most homes and small businesses will find plenty of power in the Protector Series with standby generators from 15 to 60 kilowatts. Larger power needs should consider the Commercial Series with units from 70 to 150 kilowatts.
