By the recent trends the households have a lot of intelligent, programmable electricity consumer devices and some generation units as PV too. The new network structure of the residential inhouse power systems suits to the requirement of the security, autonomy, renewable generation and economy. This suppose a parallel DC network that get directly the PV generation, stores that, supplies the LED lighting and DC drives of the heating-cooling. In normal state the loads are supplied from the utility power system or the PV generation feeds back to the utility. Some critical loads require uninterruptable supply, e.g. heating system's circulating pumps, security devices, communication and emergency lighting. In case of outage of main grid the house turns into island operation mode, where the generation, storage and loads must be managed to keep the equilibrium. A balance manager electronic has been planned that controls the load situation and the state of the storage device, makes decision about the island operation and the derogated functionality. The paper gives the structure of the electronic and simulation about its operation. This local device can contribute to the intelligent operation of the whole network, to the smarter grid.
