Auxiliary Power Units For Greenhouse Operations

Y. Zhang, J. A. Watson, R. A. Bucklin, and R. W. Henley

Greenhouses require energy to thrive. Most greenhouses require fans, water pumps, heating equipment for operation. A backup generator will keep a greenhouse operational with uninterruptible power supply. When selecting a generator, it is crucial to know how much power the backup generator needs to maintain the essential operations of the greenhouse. Besides, choosing a proper unit and installing and operating it correctly are critical for success. This article provides guidelines for generator s
