I hope your relays are rated for high current DC switching. Are they magnetic blow out? With high current DC you need something to break the arc, Mangetic blow out relays use a high powered magnet to blow the arc away from the contacts thus breaking it. Normal relays will weld shut or catch fire if the arc is big enough. Nice to see a new video, about to get 7.5kAh battery set up, along with 20 nice panels on the roof. So with luck i'll be generating all i need to power my part of the internet soon.
We assume PK is a trained electrician and he should be well aware that dc high current LV systems are a world of their own, not understood by mere amateur dabblers who fancy a bit of solar. Its really quite difficult to source legitmate fuse links , breakers (there are no proper rated mcbs btw for thisd duty). You need an AIC amps interrupt current of 20kA - yes 20,000 Amps. Think of a stickwelder arc flash x 1000.
