2.1 Intended Use
The SMA I/O Module is a module with 6 digital inputs and 1 digital output operating as a
multifunction relay. The SMA I/O Module enables the implementation of grid management services
for up to 12 SMA inverters in a network with the same system password. The SMA I/O Module
must be installed in one SMA inverter. For the implementation of grid management services, the
SMA I/O Module receives the specifications of the grid operator via a ripple control receiver. The
SMA I/O Module transmits the specifications of the grid operator via Speedwire network to a
maximum of 11 further SMA inverters. The multifunction relay can be configured for various
operating modes. The multifunction relay can, for example, be used for switching fault indicators on
and off.
The product must only be installed in the following SMA inverters:
• STP 50-40 (Sunny Tripower CORE1)
• STP 50-41 (Sunny Tripower CORE1)
• STP 50-JP-40 (Sunny Tripower CORE1-JP)
• STPS30-20 (Sunny Tripower Storage X 30)
• STPS50-20 (Sunny Tripower Storage X 50)
• SI30-20 (Sunny Island X 30)
• SI50-20 (Sunny Island X 30)
The inverter still complies with the standard after the product has been installed.
All components must remain within their permitted operating ranges and their installation
requirements at all times.
The product must only be used in countries for which it is approved or released by SMA Solar
Technology AG and the grid operator.
Use SMA products only in accordance with the information provided in the enclosed
documentation and with the locally applicable laws, regulations, standards and directives. Any
other application may cause personal injury or property damage.
Alterations to the SMA products, e.g., changes or modifications, are only permitted with the express
written permission of SMA Solar Technology AG. Unauthorized alterations as well as failure to
observe the documentation will void guarantee and warranty claims and in most cases terminate
the operating license. SMA Solar Technology AG shall not be held liable for any damage caused
by such changes.
