Crimping tool Knipex 97 33 03 MultiCrimp for PV connectors MC4 and MC4 EVO2

The Knipex 97 33 03 MultiCrimp for PV connectors MC4 and MC4 EVO2 is a specialist crimping tool engineered for reliable termination of photovoltaic (PV) cables. Designed by Knipex for electricians and photovoltaic installers, the tool creates consistent mechanical and electrical crimps on MC4 and MC4 EVO2 connectors used in solar panel systems. Its construction supports repeated field and workshop use, delivering secure, low-resistance connections required for safe energy transfer in PV installations.

Advantages

The MultiCrimp combines a robust mechanical design with precision crimping geometry to ensure reproducible contact formation and minimal contact resistance. It is built for durability with materials and joint design that resist wear in frequent use. Ergonomic handles reduce operator fatigue during repetitive crimping tasks, while the tool’s alignment and die shape simplify correct connector positioning, lowering the likelihood of faulty crimps.

Suitable for

• Crimping MC4 photovoltaic connectors in residential and commercial solar installations
• On-site PV system installation and maintenance work
• Workshop preparation of PV cable assemblies and replacement of connector terminations

Key specifications

• Connector compatibility: MC4 and MC4 EVO2 PV connector types
• Operation type: manual crimping tool with precision die
• Intended conductors: PV cable conductors used with MC4 systems
• Ergonomics: insulated, shaped handles for repeated use
• Application environment: suitable for field and workshop use

How to use

Inspect the connector and stripped conductor for correct dimensions and cleanliness before crimping. Insert the conductor into the MC4 or MC4 EVO2 contact according to the connector manufacturer’s instructions, position the contact fully into the crimping die, and close the tool handles evenly until the crimping cycle completes. After crimping, visually and mechanically inspect the crimped joint to confirm the conductor is secure and that the crimp profile matches the expected geometry for MC4 contacts.

Recommendations

Use with compatible MC4 and MC4 EVO2 contacts and PV cable sizes only. Follow connector manufacturer torque and assembly specifications for the mating parts and any insulation sealing steps. Periodically check the tool dies for wear and keep the tool clean and lightly lubricated at the pivot to maintain consistent crimp quality.
