STP T2 forty PV is the sequence of gadgets that grant superior overvoltage safety to photovoltaic structures via utilising Mersen’s optimized dynamic thermal disconnection system, which does no longer require extra overcurrent safety (back-up fuse) due to its excessive short-circuit stand up to rating. These surge defensive units are appropriate for all PV applications: large-scale, rooftop and self-consumption (off-grid) DC installations. The collection consists of unique multipole merchandise for more than one MPPT (Maximum energy factor tracker) inverters.
