SMA now offers the SMA Com Gateway for PV system monitoring and control. The name of the device says it all \u2013 as a gateway, it provides PV systems featuring RS485 data communication with access to state-of-the-art SMA Speedwire communication. Below, we\u2019ve summarized seven important questions and answers on the new communication device. <\/strong><\/p>\n

<\/p>\n

 <\/p>\n

1. As a PV system operator, when should I purchase the Com Gateway? <\/strong><\/p>\n

The SMA Com Gateway<\/a> is an attractive option if you want to modernize the functional performance of your system without replacing all of the communication wiring. The gateway enables existing systems to be upgraded with SMA Speedwire devices, for example to allow direct marketing of PV power. For instance, if an RS485 data logger such as the Sunny WebBox fails, you could install an SMA Cluster Controller<\/a> in combination with the Com Gateway or, in the future, even an SMA Home Manager.<\/p>\n

 <\/p>\n

2. Can I keep my old WebBox? When should I replace it?<\/strong><\/p>\n

As the RS485 bus is a single master bus, it is not possible to operate Sunny WebBox and SMA Com Gateway at the same time. In larger systems, however, a mixed system solution that combines SMA Com Gateway + SMA Cluster Controller and Sunny WebBox + Power Reducer Box is also possible if, for example, one of several installed Sunny WebBoxes fails. This involves the installation of either a WebBox or a Com Gateway in an RS485 bus.<\/p>\n

 <\/p>\n

3. What does the future of RS485 communication for PV systems look like? Will this standard soon be a thing of the past?<\/strong><\/p>\n

No. In the future you will, of course, still be able to use the SMA Com Gateway to build new PV systems with RS485 and integrate them into cutting-edge control and monitoring solutions. However, not all functions will be possible with devices in the RS485 bus, particularly if rapid open-loop and closed-loop control is required. SMA therefore recommends always using SMA Speedwire technology for data communication in new PV systems.<\/p>\n

 <\/p>\n

4. Is it now possible to integrate old Sunny Tripower inverters into Sunny Portal again using the Com Gateway?<\/strong><\/p>\n

Most SMA inverters featuring an RS485 interface can be integrated into Sunny Portal using the combination of SMA Com Gateway + SMA Cluster Controller. The specific inverters in question are described in a technical information sheet, which can be found in the download area<\/a>\u00a0as soon as it will be available.<\/p>\n

 <\/p>\n

5. When will I be able to integrate systems via the Home Manager? <\/strong><\/p>\n

The SMA Com Gateway is already designed to be integrated, in conjunction with the Home Manager, into the SMA Smart Home. Plans for necessary adjustments to the Home Manager are still in progress.<\/p>\n

 <\/p>\n

6. In which countries can I already obtain the SMA Com Gateway and use it?<\/strong><\/p>\n

The product is designed for global use and is certified to CE and FCC standards. The SMA Com Gateway including documentation in the corresponding national language is available for Germany, the U.S., Canada, France, Spain, Greece, the Netherlands, Belgium, Portugal and the Czech Republic. For other countries in which the product can be used, it is recommended that you inquire about any additional certifications that may be required.<\/p>\n

 <\/p>\n

7. How is the device installed?<\/strong><\/p>\n

The SMA Com Gateway is designed as a top-hat rail or wall-mounted device and is therefore easy to install. Simply connect the device in line with the Cluster Controller (daisy chain) via SMA Speedwire using both the Ethernet and SMA Speedwire connections. In combination with the Cluster Controller, it is possible to supply both devices with one power supply unit. This makes for a convenient solution taking up less room in the switch cabinet. Both of the LEDs on the front of the Com Gateway give you an overview of the current status of the device. This is important when entering the devices into the RS485 bus during commissioning, for instance. You can also conveniently view all of the device functions via the SMA Cluster Controller as well as parameterize and initiate RS485 device detection.<\/p>\n

 <\/p>\n

The SMA Com Gateway is available for order now with delivery starting the middle to end of December.<\/em><\/p>\n
