Abstract
An energy management system for an elevator installation coupled to a source of alternative energy integrates various operational modes regarding optimization of energy usage. The energy management system selectively executes these modes depending on at least one predetermined parameter of a variety of parameters. The energy management system has a processor and a switch module coupled to the processor to receive a control signal from the processor. Upon processing of at least one of the parameters, the processor selects one of a plurality of operational modes of the elevator installation and generates the control signal as a function of the selected operational mode to cause via the switch module an energy flow from one of the inputs of the switch module to the output of the switch module.
