What is the Sofamel collection and what does it offer?
The Sofamel collection brings together professional electrical connection solutions: insulated hollow ferrules, tubular compression terminals, metric eyelets (M6–M12), splices, and small accessories designed for panels and wiring in solar installations. Its value lies in ensuring uniform, traceable, and standard-compliant crimping, improving the reliability of the photovoltaic system.
Advantages and limitations
- Wide variety by conductor cross-section (e.g., 0.5–95 mm²) and by screw diameter (M6, M8, M10, M12).
- Tinned finish for lower contact resistance and better corrosion resistance.
- Quality insulation with color coding (easy identification during assembly and maintenance).
- Limitation: require a suitable crimping tool and correct tightening torque to guarantee certification of the assembly.
Applications
- PV string and connections in connection and terminals inside combiner boxes.
- AC/DC electrical panels and busbars for DC protection.
- Interconnection of solar cable with inverters, charge controllers, and batteries.
- Machinery, marine, industrial vehicles, and low voltage automation.
How to choose correctly
- Cable cross-section (mm²): must match the ferrule/terminal to avoid looseness.
- Type of terminal: hollow ferrule for flexible wires; tubular/eyelet for screw (M6–M12) in terminals and batteries.
- Barrel length and insulation: according to terminal depth and required protection level.
- Material and finish: tinned electrolytic copper for lower resistance and better protection.
- Environment: use in panel or outdoors inside enclosures (suitable IP rating for electrical panels).

Good installation practices
- Use the correct crimping die for each cross-section.
- Remove just the right amount of insulation and avoid loose strands before crimping.
- Apply tightening torque according to the screw/terminal and record the torque in critical assemblies.
- Identify by color and label circuits to facilitate O&M.
