Abstract

A method for supplying internal consumers in a domestic appliance from a low voltage supply network, for example a photovoltaic power station or wind power station, includes classifying the internal consumers commensurate with a stored energy requirement of each internal consumer and supplying the internal consumers with energy commensurate with the classification. This protects against low voltage and excessive electric loads and against partial interruption of a treatment program for items when the low voltage supply is interrupted due to a temporary overload. The energy supply of the internal consumers is switched off in stages depending on their energy requirement and on their classification, when the energy available from the low voltage supply network is insufficient for supplying all internal consumers, and is switched back on again in stages, when the energy available from the low voltage supply network is once again sufficient for supplying all internal consumers.
