I saw a youtube video recently where the guy suggested that a battery bank should have what I think is a disconnector or a breaker placed on I think the negative pole of the battery bank. In other words, there should be a switch I can throw to cut the current to the whole thing so that I can monkey around with things without having to remove the outgoing wire from the negative terminal manually (and perhaps risk sparks? I'm not clear on this, he showed sparks but I'm not clear what situations create sparks and when that's dangerous).
In terms of placement I think it would go like this: Battery Bank --> BMS --> Disconnector or Breaker --> Shunt-Based Battery Monitor --> Fuse Boxes (I'll have 24 V and 12 V fuse boxes because the system is 24 V but a few small things will run 12 V) & inverter/charger. Right?
So obviously I'm a bit wobbly on all this would love some feedback on pretty much anything I just mentioned.
But also I'm wondering whether there's a reason I'd get a disconnector and a fuse vs getting a 300 A breaker (which I understand basically encompasses both the "disconnection" and "fuse" functions...I think). And I see some automotive breakers at that size selling for $20 or so.
