Connecting the PV Modules to the Inverters

Requirements:

  • The PV modules must be correctly mounted in accordance with the manufacturer specifications.
  • Each inverter must be connected to no more than one PV module.
  • The thresholds for the input voltage and the input current of the inverter must be adhered to.
  • The positive connection cable (DC+) of the PV module must be fitted with a positive DC connector suitable for the DC connector of the inverter.
  • The negative connection cable (DC−) of the PV module must be fitted with a negative DC connector suitable for the DC connector of the inverter.

Procedure:

  1. DANGER

    Danger to life due to electric shock

    Do not disconnect the AC connector under load.

    1. Ensure that the circuit breaker is switched off and that it cannot be reconnected.
    2. Ensure that the PV module is covered.
  2. Check the PV module for ground faults ( > Checking the PV System for Ground Faults).
  3. Check the DC connectors of the PV module for correct polarity and connect to the DC connectors of the supplied DC plug. Tip: for correct assignment, the DC plug is marked with + and ‒.
  4. The DC connectors snap into place.
  5. Make sure that the DC connectors are securely in place.
