4 Product Description
4.1 SMA Power Control Module
The SMA Power Control Module is a multifunction interface which enables grid management services
to be implemented for one inverter. In addition, the module is equipped with a multifunction relay.
For the implementation of grid management services, the module receives the specifications of the grid
operator via a ripple control receiver. In total, there are 16 setting possibilities or entry combinations.
The module can implement the following grid management services:
• Active power limitation in staged intervals of 0%, 30%, 60% and 100% of the agreed
connected active power
• For systems with a maximum power output of 6 kW and only in conjunction with inverters of
type SB xx00TL-21, SB xx00TLST-21, SB xx00SE-10:
– Remote shutdown within 50 ms
– Narrowing of the frequency limits to between 49.5 Hz and 50.5 Hz
The multifunction relay can be used for the following functions, for example:
• as fault indicator or operation signaling contact
• to control an external load or charge batteries
• to report the switching status of the grid relay (report start of grid feed-in to grid operator)
