The case (100) has a reversible converter (C20) connected to a battery (B10) and directly interconnected with a power bus (M100), where a photovoltaic generator (V), a wind generator (E), an electric generator (G) and a water turbine (R) are connected to the power bus through converters (C30, C40). The power bus, the electric generators and the reversible converter form a local micro network for supplying electric energy to domestic consumers. A voltage level and frequency of the power bus are set by the reversible converter by using an electric unit. |
