Switching and Protection Solutions for Self-Consumption Solar Installations

What is solar self-consumption?

A solar self-consumption installation is a system designed to generate electricity from solar energy, aiming to meet the electrical consumption needs of a residential, commercial, or industrial facility. Photovoltaic self-consumption has become an efficient and sustainable alternative for energy supply.

What protection components are needed in a self-consumption installation?

The increasing adoption of solar self-consumption systems has highlighted the need to implement proper sectioning and electrical protection solutions. These measures not only ensure system safety but also optimize its performance and extend its lifespan.

• Photovoltaic Inverter: A key component in photovoltaic self-consumption installations. Its main function is to convert the direct current (DC) generated by solar panels into alternating current (AC) for domestic consumption.

• Battery Storage Systems: : Batteries are a fundamental component of solar self-consumption installations, especially for those aiming to maximize energy usage. They allow energy storage during the day for use when solar production is low. These batteries must be protected with gBat curve fuses.

• Rapid Shutdown Switch (DC): : Enables quick disconnection in case of emergency, protecting both users and equipment in case of fire. It should be installed as close as possible to the solar panels.

• AC and DC Disconnectors: : Ensure safe disconnection of the direct current (DC) circuit between the panels and the inverter or the alternating current (AC) circuit between the home and the inverter, maximizing safety in case of emergency or maintenance.

• Solar Protection Panels (DC): : Incorporate a load break switch, surge arresters, and gPV curve fuses, providing comprehensive protection for the photovoltaic system. Protection panels are key elements in any electrical installation, and in self-consumption solar systems, their role is even more critical.

Proper integration of protection panels, disconnect switches, inverters, and batteries is crucial to ensure the efficient and safe operation of the solar self-consumption system. It is recommended to work with professionals for system installation and design, ensuring that all components comply with established regulations and are properly sized for the specific needs of each installation.
