for PV plants larger than 30 kVA the use of an external power dis-
connection device (Netz- und Anlagenschutz) with clutch switch.
(2) Alternatively, VDE-AR-N 4105, section 6.4.1 allows the use
of an inverter with an internal clutch switch if the internal clutch
switch disconnects the inverter from the AC grid within less than
100 ms.
This inverter fulls (2) when the following rmware versions are
installed: DSP ≥ 1.30 / RED ≥ 1.20 / COMM ≥ 1.10. For inverters
with these rmware versions, an external power disconnection
device is not needed.
Beside the parts delivered with the inverter (see “4.1 Scope of
delivery”, p. 10), you may need the following additional parts
