Connect PV (DC cable)

Observe the Information on cable requirements and minimum bending radii for inverter, meter and battery.

The scope of delivery includes Stäubli MC4 Evo 2A PV connectors, which are compatible with the Stäubli PV connection sockets on the inverter. Stäubli PV plugs are compatible with other types of Stäubli MC4 plugs.

  • Strip the DC cable to a length of 6.0 - 7.5 mm
    Make sure that no individual wires are damaged!
  • Crimp the DC cable to the PV connectors
    Ensure correct polarity when assigning the PV pin contacts!

Strip PV cable
  • insert the crimped contacts into the contact bodies of the plugs until they click into place
    When the contacts are fully inserted, you will hear a 'click' sound.
  • carefully pull the cable to check that the pin contact is correctly engaged
Introduce crimped contact
  • Pre-tension the cable gland using the PV-MS-PLS tool
  • Tighten the cable gland with the PV-WZ torque set (see table for torque in Nm) and support the connector front using the PV-MS-PLS tool
Tighten the cable gland
