Yet another example.
A couple of years ago people were buying 100 amp shunts.
100 shunt amps * .66 = 66 service amps
66 service amps / .8 fuse headroom = 82.5 amps
That means 6 awg and a 100 amp fuse.

Hello all - trying to figure out fuse size for the Victron Lynx Shunt VE.Can. Have a Multplus II 3000/48v unit, and 3 trophy batteries as backup for the house. Running 2/0 cable from Multi to Lynx Distributor, and 2/0 from the Lynx Power In to the batteries. A Victron MPPT and the Cerbo are in play as well - but the MPPT will only be used in a grid down situation and then will put out ground mount panels if needed. The batteries are (1) 48V220E-1 and (2) 48V100E-1 units, but would expect to expand more in time. The Lynx Shunt that sits between the Power-In and the Distributor uses a CNN/ANN fuse. What should the proper size of fuse be for the Victron Lynx Shunt be in this config - and what is the math behind it? Thanks in advance!
