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
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, we expect that the first products with Wi-Fi reinstated will be delivered in the course of the 4th quarter.

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

Are there any other limits in the functions of the affected products?

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

Will it be possible to add this function at a later date?

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

What is the schedule for the changeover? When will customers and wholesalers be informed?

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

How can a distributor / specialist dealer see that the device does not have Wi-Fi?

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

How can an installer see that the device does not have Wi-Fi?

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.

Can I exchange the device with no Wi-Fi for one with Wi-Fi at a later date?

Unfortunately, that is not possible.

Will the devices be equipped with Wi-Fi again in the future?

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.

Does this also affect the SMA Data Manager M?

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.

Are the datasheets being amended?

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

Is there an alternative solution for wireless integration into a network?

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.

If the SMA Data Manager is not equipped with Wi-Fi, does this mean my system’s inverters will not be recognized?

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).

How can commissioning be carried out without Wi-Fi?

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.

How can integration into a local network (home network) be achieved?

Is it still possible to use the SMA 360° app?

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

Will there be a new item number?

No.

Will there be a new type designation?

No.

Will it be obvious on the order confirmation how many / which products will be delivered with/without Wi-Fi?

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.
