What does the Electrical Material collection include?

The Electrical Material collection groups together the components that ensure conduction, connection, conversion, and protection of energy in a PV system: halogen-free cabling, MC4 and power connectors, DC-DC converters, enclosures and panels, and coordinated protections in DC and AC.

Advantages and limitations

• Technical consistency: selection oriented towards photovoltaics and low voltage.
• Safety and standards: products with suitable IP/IK ratings and common certifications.
• Availability of formats for residential, agricultural, and light industrial use.
• Limitations: predetermined electrical values; check the specific voltages/currents for your project.

Applications

• Grid-connected self-consumption (residential and SMEs).
• Off-grid systems 12/24/48V and high voltage (HV).
• Solar pumping and pool purification.

How to choose

• Define voltage and current per string and per AC branch.
• Select cables by cross-section, material, and fire reaction class.
• Use connectors/terminals compatible with the conductor and equipment.
• Integrate DC protections and AC protections with suitable coordination and breaking capacity.
• Centralize in panels and boxes to facilitate maintenance.

Typical specifications

Best practices

• Respect bending radii, tightening torque, and terminations.
• Separate DC/AC runs and protect against abrasion and UV.
• Clear labeling and diagrams in the electrical panel.
