I/O interface as retrofit kit for STP 50-40 (Sunny Tripower CORE1)
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.
