Solerm Self-supply

Presentation:

The Solerm Self-Consumption system is a photovoltaic solution designed for residential, commercial, or industrial installations. Its main objective is to reduce dependence on the electrical grid by producing renewable energy locally, close to where it is needed.

Its architecture is based on micro-inverters installed behind each photovoltaic panel, which improves flexibility, individual panel optimization, and overall performance.

The system includes:

• Photovoltaic panels that generate electricity from sunlight
• Micro-inverters that convert direct current (DC) into alternating current (AC) with individual optimization
• Specific cables and connectors for system connections
• A protection enclosure and an electrical distribution board
• A communication gateway that enables data collection and monitoring
• An online supervision center for performance tracking

This system makes it possible to optimize electricity consumption, reduce dependence on the grid, sell surplus energy produced, and improve self-consumption through battery storage.

Technical solutions :

Direct and alternating current (grid-tied Enphase microinverter, 230V, 360W)
Photovoltaic power generation: 750W (2×375W) or 1500W (4×375W), depending on the version
Communication and monitoring via the cloud (Enphase Envoy gateway)
Safety of photovoltaic systems (surge protection, etc.)

Training activities:

The Solerm Self-Consumption system is supplied with supporting documentation including 7 educational scenarios in Cpro format, with detailed instructions and answer keys.

Scenario 1: Discovery of the “PV Self-Consumption” system.
The student follows a tutorial that guides them through discovering the components of the self-consumption photovoltaic system, its operation, and its technological and environmental developments.

Scenario 2: Installation and connection of PV modules with micro-inverters and the UTE 15-712-1 protection box.
The student becomes aware of the differences between types of current (direct or alternating), understands the influence of module orientation and tilt, and follows a connection guide while performing post-installation checks.

Scenario 3: Installation and wiring of the “UTE 15-100” distribution board and the “UTE 15-712-3” storage battery.
The student installs and wires the storage and regulation unit, connects it to the main electrical distribution board, and performs post-installation checks.

Scenario 4: Installation and wiring of the ENPHASE ENVOY gateway and network connection.
The student installs and connects the ENPHASE ENVOY gateway and configures the network connection in order to collect data on the Enphase Energy cloud platform.

Scenario 5: Technological choices and installation study of a PV generator.
Performance is analyzed and monitored according to the choice of PV cells and environmental conditions. The student selects the type of silicon, chooses the structural components, and determines the installation conditions of the PV generator according to site constraints (environment, sunlight exposure, orientation, tilt, shading, wind, lightning, etc.), in compliance with the specifications to achieve maximum efficiency.

Scenario 6: Commissioning and installation of a photovoltaic generator.
The student performs self-checks on the PV self-consumption installation in compliance with standards NF C 15-712-1, NF C 15-712-3, and NF C 15-100. The student also learns about the administrative procedures required for connection requests, then completes the certificate of conformity and the mandatory ENEDIS agreements.

Scenario 7: Delivery of a self-consumption photovoltaic installation.
The student performs self-checks on the PV installation in compliance with standards NF C 15-712-1, NF C 15-712-3, and NF C 15-100. The student carries out dynamic system checks and online operation monitoring, presents the system to the client, and completes the intervention report.

Key points:

• Educational activities provided in the form of CPRO Bac Pro MELEC scenarios with answer keys
• System delivered assembled and ready to use, easily movable and simple to operate; adapts to all situations and users
• Hybrid system: can be used for both “self-consumption” and “full grid feed-in” (selling all electricity to the utility provider)
• Smart system: with a measurement and communication gateway, the installation is continuously monitored 24/7, with data recorded in the cloud, allowing visualization and analysis of production and system efficiency depending on sunlight exposure
• Scalable system: designed to accept additional photovoltaic panels and centralized Enphase energy storage batteries
