Growatt 5000ES 240v wiring question

[Averageaviator]

I'm not entirely sure how to go about the AC input wiring from my panel. My plan was to use this 30a dual pole from my main panel that I was using originally as a gen input with a lockout kit. Eventually I will do a sub panel with basically everything from the main panel minus the dryer and A/C unit. The instruction manual must be designed for EU wiring colors because it refers to a blue neutral and a brown line ?? Obviously in my panel the ground and neutral are tied to the same bar and my grounding/bonding screw is used also in the panel. Help a guy out, probably a simple answer for most on this forum, but I still have a lot to learn. thanks all

BTW, I understand the manual states a 50a breaker on 8ga wire......this is temporary just to power the unit for the purpose of charging my GYLL batts
