The good news for all owners of PV systems with RS485 data communication is that with the SMA Com Gateway, even existing systems can benefit from all options of the modern SMA Speedwire data communication.
Whether it’s a system upgrade or expansion, the SMA Com Gateway allows the use of the SMA Cluster Controller and thus integration of current and future system monitoring and system control solutions, such as commercial energy management. The PV system’s investment security is therefore guaranteed.
A list of all devices can be found in the Technical Information “SMA COM GATEWAY - Compatibility and Application Options” (see Here).
An SMA Com Gateway can support up to 50 devices. For larger systems, several SMA Com Gateway devices can be used in parallel with one or more SMA Cluster Controller.
Yes. With the SMA Cluster Controller and the SMA Com Gateway, hybrid systems of R S485- and Speedwire-wired devices are possible.
The SMA Com Gateway is a media and protocol gateway that allows communication devices, such as the SMA Cluster Controller, to access devices in the RS 485 bus and to visualize, parameterize and control them. Individual Sunny WebBox functions, such as the RPC interface, Sunny Matrix and Flashview, are no longer supported. These applications can be implemented in various ways by using SMA Cluster Controller functions (e.g., via Modbus interface).
From version 1.03.31.R
Yes, the version 1.07.29.R of Sunny Explorer devices in the RS485 bus can now be accessed via the SMA Com Gateway.
