Why do you think Will decided to use both, he must have a good reason
maintenance. you cant turn off a fuse.Why do you think Will decided to use both, he must have a good reason
What 5awg cable can handle 180A without catching fire?
Ah right so I need a 120 Amp circuit breaker or thicker wire. So the inverter came with 5 AWG wire to connect it to a battery as it uses around 125 Amps absolute max, but running more DC loads through that would set it ablaze.What 5awg cable can handle 180A without catching fire?
Yea this is why I want to use the circuit breaker for everything instead of the fuse - so I won't have to replace a fuse but mainly so that when I disconnect/reconnect battery I don't get a spark charging up inverter capacitorsmaintenance. you cant turn off a fuse.
you dont have to do anything really. but whichever safety measures you choose not to implement increase your risk for hazard ~ like welding a wrench to your system and incinerating personal property.
It's actually 16mm squared which is actually a bit under 5AWG as well. It does get a bit warm after using anything high-draw, but never too hot to holdIsn't 5AWG a bit small for a 1500W inverter at 12V too?

Is it safe enough to use two, three 5AWG cables in parallel instead of one large 1 or 2AWG? $160 AUD for 25 feet of 1AWG!Yeah, we're in the metric world so I converted to 16mm2. Bangkok Cable puts their 16mm2 at 95A in free air.
It's not going to explode everywhere but if you are running constantly anywhere near 90A I'd be looking at bigger cable.

The connectors and internal wiring of the controller are designed for 40 amps. An internal fault would flow current only limited by a fuse or breaker in the path between controler and battery.What is the reasoning behind a 50 Amp for a 40A MPPT?
Alright so you go about 10 Amps over what's rated for that equipment so that if something goes wrong, it will only go around 10 amps over and not more? If I had a 80A MPPT for example I would get a 90A circuit breaker/fuse? Assuming it's not safe to trust the device itself as Will has included this in his systemsThe connectors and internal wiring of the controller are designed for 40 amps.

Your 180 or 120 breaker may alow a fire within the faulty controller.
Overcurrent protection is need for the cable rating and whatever current rated device is on the end of that cable.
You have a similar issue with the fuse box, it will have a maximum current rating.
