My set up is a 200ah 24V battery made with 16 Frey (Fortune) 100ah cells). Between the battery box and the rest of the power system is a 32 in long chee fridge/freezer. Everything will be mounted fairly close together with room for air to circulate on a plywood sheet. The DC-DC charger will have a fan.
I have a Blue Sea 100 amp fuse box. Should I fuse it at 100 amps or 100 x 1.25 = 125A if the wire can handle it. I have a 100A attery protect between the distribution and DC fuse box. Should there be a fuse there too?
Is a 350 amp fuse too big for a 2/0 battery cable? The battery cable length should be about 9 ft. roundtrip but definitely under 10.5 ft. Blue Sea Wizard says 2/0 is good for 330A at up to 28 feet but 331A 1 ft. circut needs 3/0. It doesn't say if that's for voltage drop or safety. My victron Multiplus calls for 1/0 wire and a 300 amp fuse. According to that same calculator a 1 ft. length circuit with 1/0 can't carry more then 285 amps, and at 28 ft the limit is 261 amps yet the circuit needs a 300 amp fuse to be safe. The inverter and DC panel will be within 2 feet of the Lynx distributor. Most DC loads will be less then 5 feet if the DC panel. The exception being diesel heater pump and a water pump with a max amps of 2.4 amps (24V).
So confused. Please help.
