There is a decent product that acts a a rapid disconnect and fusing, look up the mersen fuse disconnec t. There is quite a range of them for different amperages needed.
DC Fuses are integrated in Battery Energy Storage systems to protect the battery bank from overcurrent and short circuits, ensuring the safety of the system. Safety considerations for DC Fuses in Battery Energy Storage include using Class T fuses for LFP batteries and proper wiring to ensure safety and performance.

The integration of in battery energy storage systems (BESS) is a critical aspect of ensuring the safety and longevity of the system. DC fuses serve as a protective barrier against overcurrents that can arise from faults or abnormal operating conditions.
The types of DC Fuses used in Solar PV systems include ANL fuses, MRBF fuses, MEGA fuses, and inline MC4 fuses for parallel wiring connectors. DC Fuses are integrated in Battery Energy Storage systems to protect the battery bank from overcurrent and short circuits, ensuring the safety of the system.
Proper fusing of the battery bank is critical to prevent short circuits and potential fires. A battery fuse should be placed as close as possible to the positive terminal to ensure prompt disconnection in the event of a fault.
