Connecting PV modules to the inverter

The DC cables of the solar modules must not be connected to the inverter under load.

DANGER

danger

Risk of death due to electrical shock and discharge!

Switch off the inverter on both the AC and DC sides.

  1. Unlock the AC connection of the inverter by switching off the line circuit breaker.
  3. Turn the DC switch on the inverter to “OFF”.
  4. Measure the DC cables of the PV modules before connecting them to the inverter with the correct polarity. PV modules connected with the wrong polarity may cause thermal damage to the inverter.
    Exceeding the maximum input current per string may result in damage to the inverter. Therefore, the maximum input current per string for the inverter as stated in the technical data must not be exceeded.

INFO

Info

Observe national regulations! In France, in particular, the inverter and the supply lines must be labelled, for example.

The installer is responsible for obtaining and affixing the prescribed markings.

  1. Remove protective caps from input terminals.

  2. INFO

    Info

    Keep the protective caps of the PV connections for future use.

  3. Fit plug connectors of the individual PV strings into the DC inputs PV+ and PV- in pairs until they engage tangibly and audibly.
  2. The PV modules are connected.
