For example, the light indicator is in an “on” state when no problem is observed on the electrical network, and in an “off” state when a problem is observed on the electrical network, or vice versa. The indicator The indicator light can also be configured to display different colors depending on the status of the power grid. As in the previous example, each indicator light indicates, for example, the operating status of one phase of the three-phase power supply.

[0119] According to one embodiment, at least one visual indicator 300 is arranged on an external wall of the electrical room 1000. Electrical room switches

[0120] The electrical room 1000 comprises a plurality of switches Ai, ..., Ax. Each switch is capable of being actuated by a user independently of the other switches to move from a first state to a second state, or vice versa. The first state is for example an open state of the switch and the second state is for example a closed state of the switch, or vice versa.

[0121] The plurality of switches Ai, ..., Ax comprises a first switch Ab. The first switch Ai is capable of being in two states: - A first state in which it connects the direct current electrical circuit 101 to the DC / AC converter 105. - A second state in which it isolates the direct current electrical circuit 101 to the DC / AC converter 105.

[0122] The switch Ai has several advantages. A first advantage is that the possibility of isolating the DC / AC converter 105 from the direct current electrical circuit 101 allows the implementation of secure maintenance operations on equipment in the direct current electrical circuit, for example on one or more solar panels. Another advantage is that these maintenance operations can be implemented without interrupting the electrical power supply to the first electrical equipment 220 of the building 200.Indeed, in the case where the electrical equipment of the electrical room 1000 is isolated from the direct current electrical circuit 101, the first electrical equipment 220 of the building 200 is powered either directly by the electrical network, or totally or partially by the electrical energy resulting from the production of one or more solar panels stored in one or more electrical energy accumulators 103 and circulating in the alternating current electrical circuit.

[0123] Another advantage of the switch Ai is that it makes it possible to isolate the direct current circuit 101 from the second electrical equipment 120 without switching off the DC / DC charger regulator.

[0124] The electrical room 1000 comprises a second switch A2. The second switch A2 is capable of being in two states: - A first state in which it electrically connects the first set of electrical equipment 220 of the building 200 to the live electrical circuit alternative 102. - A second state in which it electrically isolates the first set of electrical equipment 220 of the building 200 from the alternating current electrical circuit 102.

[0125] An advantage of the second switch A2 is that, when it is in the second state, it is possible to intervene on one or more first electrical equipment 220 of the building 200 without facing an electrical risk. Another advantage is that, when the second switch A2 is in the second open state, it is still possible to produce electricity from one or more solar panels 104, and to store it in one or more electrical energy accumulators 103. Thus, maintenance operations can be carried out while continuing to produce and store electricity.

[0126] The third switch A3 is capable of being in two states: - a first state in which it electrically connects the first set of electrical equipment 220 of the building 200 to the DC / AC converter 105 and to an external electrical network via the alternating current electrical circuit 102; - a second state in which it electrically connects the first set of electrical equipment 220 of the building 200 only to the external electrical network via the alternating current electrical circuit 102.

[0127] Thus, the third switch A3, when it is in its first state, allows the supply of electric current to the first electrical equipment 220 of the building 200 directly from the current stored in the electrical energy accumulator 103, and also allows this supply to be supplemented by a supply of electric current from the electrical network.

[0128] When the third switch A3 is in its second state, it allows the supply of electrical current to the first electrical equipment 220 of the building 200 only from the electrical network. In other words, in this configuration, the electrical room 1000 “is removed from the network”, and the alternating current resulting from the conversion of the direct current from the solar panels is not used to supply the first equipment 220 of the building 200.

[0129] One advantage is to allow the implementation of a maintenance mode on the electrical room 1000 while ensuring continuity in the power supply of the first electrical equipment 220 of the building 200.

[0130] According to one embodiment, the electrical room 1000 comprises a fourth switch A4 capable of being in a first closed state in which it electrically connects the first set of electrical equipment 220 of the building 200 to the alternating current electrical circuit 102, and capable of being in a second open state in which it electrically isolates the first set of electrical equipment 220 of the building 200 from the alternating current electrical circuit 102. In other words, an activation of the fourth switch A4 to switch it from a first state to a second state allows an emergency shutdown of the electricity supply to the first electrical equipment 220 of the building 200 and the electrical energy accumulator 103 of the electrical room 1000 jointly.

[0131] Optionally, the electrical room 1000 comprises a plurality of first switches Ai, and / or a plurality of second switches A2> and / or a plurality of third switches A3, and / or a plurality of fourth switches A4. For example, the electrical room 1000 may comprise a plurality of switches each capable of switching from a first state to a second state to connect / disconnect one or more solar panels 104 of a plurality of solar panels from the direct current electrical circuit 101. An advantage is to be able to intervene on a solar panel or a group of solar panels independently of the other panels, to allow targeted maintenance without interrupting the entire solar production.

[0132] Optionally, the electrical room 1000 comprises at least one switch arranged on an external surface of said room 1000, for example an external face of the cladding 150, or in its vicinity. This is for example a “punch” stop. An advantage is to allow a cut-off of at least a portion of an electrical circuit or an emergency stop of the entire electrical system 100 without having to enter the room. This allows a faster intervention, for example if the room has means for locking access to its interior zone, and / or a more secure intervention if access to the interior zone presents a human risk, for example an electrical risk or a risk resulting from the start of a fire.
