Company typePhotovoltaic protection and connectivity brand

Proauto Solar is presented as the division of Proauto Electric dedicated to protecting photovoltaic systems. Its portfolio brings together connectivity, surge protection, fuses, switches, panels and string boxes.

The SC4 family covers straight pairs, panel connectors, Y branches and fused or diode versions. Visual similarity to other connectors on the market does not create certified compatibility.

Focus and technology

Proauto focuses on SC4 connectors, protection, disconnection and string boxes.

  • A broad line of photovoltaic connectors and accessories
  • Integration with the brand's protection devices and string boxes
  • Public technical catalogs for the SC4 family

What to check before buying

Use the housing, metal contact, tool, torque and cable allowed by the same documentation. Do not mate SC4 with another manufacturer's MC4 just because it fits; a mixed pair can overheat and void certifications.

Buying Proauto equipment in Brazil

Confirm voltage, current, IP rating, cable cross-section, tool and warranty of the SC4 code. For fused or diode connectors, validate polarity, current, heat dissipation and the exact application.
