Mounting the WLAN Antenna

If the Wi-Fi range is insufficient, the signal can be enhanced with a Wi-Fi antenna.

Additionally required material:

  • 1 passive Wi-Fi antenna with cable and SMB socket

  • 1 conduit (trade size: 19.05 mm (0.75 in) or smaller with suitable reducer bush)

  • Sealing compound for sealing the join between the conduit and inverter if a weep hole has been added to the conduit

  • 1 rain-tight conduit fitting or conduit fitting for wet locations complying with UL 514B (trade size: 19.05 mm (0.75 in) or smaller with suitable reducing bush)

Procedure:

  1. Disconnect the inverter from all voltage sources ( > Disconnecting the Inverter from Voltage Sources).
  2. Remove the filler plug from the middle enclosure opening.

  3. Insert a conduit fitting in the center enclosure opening and tighten with the counter nut from the inside.
  4. Plug the SMB socket of the Wi-Fi antenna into the connector for the Wi-Fi antenna of the inverter.
  5. Attach the conduit to the conduit fitting.
  6. Ensure that the cable is secure by gently pulling on it.
  7. If a weep hole has been added to the conduit, seal the conduit with sealing compound.
  8. Install the antenna as far away as possible from the inverter in order to achieve a wide Wi-Fi range. Do not attach the antenna to the enclosure of the inverter.
  9. Information: The appropriate Wi-Fi antenna is automatically selected depending on the connection quality. The currently active antenna is displayed via the instantaneous value WiFi antenna type.
