Lotfi, Electrolyzers cannot be turned on and off instantaneously. In order for them to produce sufficiently pure hydrogen, they either need to remain on standby (thus have some idling power provided to them at all times) or the power input to them needs to be ramped up slowly to the idling power level over the course of 10 minutes to half an hour. In the example, the Type100 power controller is set to always provide a 5kW idling power to the electrolyzer; thus the electrolyzer produces a small amount of hydrogen at all times. It is assumed that the idling power would come from a connection to the power grid. Kind regards, David Lotfi Ziani wrote:
