Fronius Reserva InlineFuse 50A MC4-Evo stor DC Fuse 42,0411,0546,IK
DC inline fuse for multi-tower installations of the Fronius Reserva
The Fronius Reserva InlineFuse 50A is a DC inline fuse for Stäubli MC4-Evo stor connectors, used in multi-tower installations of the Fronius Reserva whenever the maximum permissible DC cable length between the inverter and the last battery tower is exceeded. The fuses are integrated directly into the DC cables between the inverter and battery as well as between the battery towers, reliably protecting the system against overcurrent and potential damage.
Note for older Fronius Reserva battery storage systems: All Fronius Reserva battery storage systems whose BMS was produced and packaged before 11 July 2025 require their own connector and are compatible with the Amphenol H4 Plus connector – available directly from Fronius.
