SMA Power Limiter

On January 14, 2020, the Federal Court of Justice (Germany) ruled on the need to remotely control PV systems. According to §6 German Renewable Energy ACT 2012 (now §9 Renewable Energy Act 2017), systems must be provided with a technical device that enables the PV system to be fed into the power grid. The Federal Court unequivocally interpreted “reduction” in such a way that simply switching the PV system on and off does not meet the requirements of the law.

The SMA Power Limiter is the SMA solution for fulfilling the prescribed gradual reduction of the feed-in power according to §6 Renewable Energy Act 2012 and §9 Renewable Energy Act 2017 as well as for quick shutdown according to EN 50549-1.
