Claim:
1. A gateway module for an electrical installation, the gateway module configured to receive, from an electrical module, a power signal through a phase line and a neutral line, the power signal including a modulated component for conveying information from the electrical module producing electricity, and configured to process the power signal to provide a compatible signal to an electrical power grid, the gateway module comprising: a main unit comprising a control circuit controlling interface means to manage information from the modulated component of the power signal and a first filtering circuit for filtering the modulated component and making the power signal compatible with the grid; at least one secondary unit including a second filtering circuit for filtering the power signal provided by the phase line and the neutral line of an additional electrical module and configured so that the interface means manages information from the modulated component of the power signal provided by the additional electrical module, the at least one secondary unit being controlled by the control circuit of the main unit, wherein the interface means includes passive coupling elements for forming connection between the control circuit and at least the phase line and the neutral line of the electrical module connected to the main unit or to the secondary unit, and wherein the interface means includes a plurality of inductive coupling elements each including a primary coil coupled by induction to a first secondary coil electrically connected to the phase line and to the neutral line of an electrical module, and to a second secondary coil, the primary coil being connected to the second primary coil of the main unit or of a preceding secondary unit whereas the second secondary coil is connected to the primary coil of the following secondary unit, the inductive coupling element configured so that the primary coil is connected to the control circuit.
