Why are NH fuses not popular in USA?
I'm building a simple, 48v MB31 battery band and will be purchasing Victron MultiPlus II 5000w inverter.
By my calculations 5000W/48v*125%=130amp
So I'm looking for 150-160amp fuse that's rated for 48-60v
In my research, I can go with either a Class T Fuse or NH fuse.
While mega fuses in 58v are available the ICC is only 2,000a, so not quite the 10x safety factor I'm looking for.
Also, it's my understanding that Class-T and NH fuses are the only ones filled with sand to help put out arc during short circuit event.
Most of people here are doing off grid houses with 10k, 18k, 22k and larger systems. What do you use for main battery fuses?
