Protection against type 2 surge arrester and a combined type 1 + 2 (DC OVP types 1 + 2) for the direct or indirect lightning strikes are particularly suitable for use with inverters Fronius Symo 10,0 - 20,0 kW and Fronius Eco. For Fronius Symo customers can choose between two options for each variation depending on the application, one embodiment of MPPT, if connected, both MPP-tracker, or a variant with multiple MPPT, if both MPP-tracker used separately.
