Easy integration of RS485 systems into the high-performance SMA Speedwire data communication
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 Data Manager or 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.
- Expands existing RS485 systems without expensive rewiring.
- Allows the use of the SMA Data Manager or the SMA Cluster Controller.
- Realizes modern system monitoring and control solutions, e.g. commercial energy management.
- Enables direct marketing of PV power.
- Allows the use of latest grid management functions thanks to the SMA Data Manager and the SMA Cluster Controller.
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.
The SMA Cluster Controller supports up to 75 devices (74 inverters and one SMA COM Gateway). The SMA Cluster Controller S supports up to 25 devices (24 inverters and one Gateway).
The SMA Data Manager M currently supports up to 50 devices (49 inverters and one gateway). Support of several Data Manager devices in one system is planned.
Yes. With the SMA Data Manager or 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 Data Manager or 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 Data Manager or 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.
The firmware version 1.00.31.R corrects general stability issues and includes some improvements (version 1.00.22.R is required to complete the update).
- Specific problems with DateTime parameters fixed
- Correction of parameter setting "Operating time for time-controlled generator op" on a SI6048U
- Correction of problems concerning update of the COMGW
- Correction of further bugs and general stability issues
Version 1.00.28.R includes a myriad of improvements. It is thus highly recommended that you update to this version (version 1.00.22.R is required to complete the update).
- Problems with internal Ethernet-Switch function have been resolved
- Interaction of control functions in connection with SMA DATA MANAGER M has been improved
- Detection and communication of missing DC currents and voltages have been corrected
- Event messages regarding the SMA DATA MANAGER M have been fixed
- Display of measured values in connection with Sunny Island inverters (and SMA DATA MANAGER M) has been improved
- Problems in displaying status values have been resolved
