Temporary discontinuation of the Wi-Fi function: successful commissioning via Ethernet interface

Global demand for electronic components and semiconductors in particular is at a consistently high level. This is due to the ongoing COVID-19 pandemic. This leads to a shortage and, as a result, bottlenecks in production at numerous manufacturers. This situation also increasingly affects the inverter sector.

In order to safeguard its ability to deliver, SMA established comprehensive supply chain risk management at a very early stage to ensure stable delivery capability under volatile market conditions. This includes a market-appropriate stocking and sourcing strategy as well as comprehensive and transparent supplier management. Together with its suppliers, SMA has developed solutions that allow it to make full use of all options for securing agreed deliveries.

However, in the current circumstances, it is unfortunately no longer possible to rule out delays in production and delivery of some products.

There are bottlenecks in the supply of the Wi-Fi modules that SMA uses in products from its HOME and BUSINESS portfolio.

The following products are affected:

MoW:

  • SB3.0-6.0-1AV-41
  • STP3.0-6.0-3AV-40
  • STP8.0-10.0-3AV-40
  • STP50-41
  • SBS3.7-6.0-10
  • EDMM-10.A
  • EDMM-10

US:

  • SB3.0-7.7-1SP-US-41
  • STP33US-41, STP50US-41, STP62US-41
  • EDMM-US-10

To ensure that deliveries of all products can continue, SMA has decided to temporarily deliver affected products without the Wi-Fi function.

As things stand today, SMA expects that the first products with Wi-Fi reinstated will be delivered from the beginning of Q4.

Successful commissioning with Ethernet communication interface

Due to the missing Wi-Fi function, the Ethernet communication interface included by default must be used for the aforementioned products for commissioning, configuration and integration of the products into a network according to the operating manual. Commissioning using the SMA 360° app is not possible. There are no further functional restrictions of the products beyond their commissioning. If it is necessary to integrate a product into a Wi-Fi network, this can be easily done using a commercially available Wi-Fi repeater that is connected to the product directly with a cable via Ethernet, for example.

Frequently Asked Questions

No, it is only the Wi-Fi function that is no longer supported.

No, unfortunately it will not be possible to retrofit this function.

We have already informed wholesalers and distributors regarding timing. Please contact your specialist dealer concerning the availability of the products concerned.

A note stating “Without integrated WLAN” will be affixed to the shipping label on the product packaging.

An additional sticker on the device reading “No WLAN integrated” will indicate this. This will be affixed near the type label (depending on the device). In addition, a note stating “Without integrated WLAN” will be affixed to the shipping label on the product packaging.

Yes, it is our clear goal to begin equipping inverters with Wi-Fi again from the beginning of Q4 2022 at the latest. We are currently unable to provide any details about the exact scheduling.

Market research on the SMA Data Manager M has revealed that it is still used predominantly with wired communication. As a result, this product will not be equipped with Wi-Fi again until the successor version is released.

Yes, the datasheets identify Wi-Fi as a feature that is “subject to availability”.

Our guide, which can be accessed above, provides you with all the information you need to integrate the product into a Wi-Fi network using a commercially available Wi-Fi repeater.

No, because the Wi-Fi in the SMA Data Manager is not used for communication with the individual inverters, but rather just with the installer’s PC or laptop during commissioning or servicing. Communication with the individual inverters / SMA components takes place via a cable using Ethernet (LAN cable).

The integrated web UI is still used for commissioning, configuring and integrating the product into a network. It can continue to be used via the Ethernet (LAN) communication interface included by default according to the the operating manual.

The integrated web UI is still used for commissioning, configuring and integrating the product into a network. It can continue to be used via the Ethernet (LAN) communication interface included by default according to the the operating manual.

Yes, you can still use the app. Only commissioning via the app is not available. This will not affect any other app functions.

The order confirmations will refer to the possibility of individual products being delivered without a Wi-Fi function. The exact number will subsequently be stated on the delivery note.
