After a little research I would like to go with one of those nifty Blue Sea battery terminal fuses.
Aside: except the one I have picked out here seems to be a slightly different model than the ones I have seen posted before.
After a little more research on fuse sizing I'm back to the forum with a question.
From a previous thread [BB I believe]:
Typically, the maximum expected current * 1.25 (or 1/0.80) for rated fuse/wiring/breakers. For example a 1,200 watt inverter running on a 12 volt battery bank (100 amps "nominal" becomes):
•1,200 watts * 1/0.85 inverter eff * 1/10.5 volts minimum battery voltage * 1.25 NEC factor = 168 amp fusing/breakers/wiring
And round up to next standard fuse/wire (175-200 amp in this example).
OK, Before I start, my Flexpower 1-6 (48v, 230VAC panel) comes with a "175ADC breaker" and a "80 amp charge controller breaker" (dont know if that helps) and a "VFX3048E" inverter.
What will be my maximum expected current. No idea really (pretty economical fridge, freezer, lights, blender)...lets go with 3000 watts (I think around the inverter max).
3000w*1/.85*1/42V (battery cutoff for a 48v bank)*1.25= 105 amps minimum circuit.
I'd then go for a 150 amp fuse.
I just need one battery fuse, right? My bank is one string of eight 6volters. This fuse should be screwed on to the battery + terminal that leads to the inverter....?
Am I on the right track my friends, or just still con-fuzed?
