An unpredictable power outage can lead to production losses and damage to valuable greenhouse plant material. Successful operation of a greenhouse water well requires the availability of electricity at all times. In the winter, electrical power is needed to run heater fans and controls; in the summer, electricity is needed to operate ventilation fans and to keep double-layered, film-covered houses inflated. An auxiliary power unit can provide insurance against losses or brown outs. A standby power system consists of a generator, an engine or tractor to power the generator, and a transfer switch.
