A processor-controlled contactor operating according to the user-selected program. It is designed to launch certain electric appliances that can wait for excess of electricity made by the alternative electric power station. Once they are launched, their whole operation cycle must finish. For example, it may be the dishwasher or the washing machine. As stated above, if the contactor connects, and the total production of the alternative electric power station lowers, or other appliances are switched on, the connector stays connected until the work cycle of the connected appliance is finished, in spite of possible passive energy balance of the power take-off.
