Hello everyone,
am trying to design my solar system as a DIY project,
after lots of research, this is how it turned out. I hope i can get feedback on whether i have made any mistakes.
I am particularly concerned because some fuses and circuit breaker calculations are different than what is suggested in the EasySolar GX II manual.
Almost exactly what I'm running, and it's working well. Your 60A output breaker seems a bit high. Can you really add them, I wasn't aware? Would 25A be better suited for a max of 5500W rated? I'd also suggest 1 x RCBO per downstream circuit (if you're planning multiple). You could also combine your battery fuse and battery iso with a breaker. Nice drawing too, what are you using?
I also say that the 60A breaker is to big.
The 3kVA Multi has 2,4kW continuous power at 25°C that is around 10A.
As long as the grid is connected the Multi will not use it's peak power (or only rarely).
Also a breaker can handle more than it's rated amps for a short time.
So 32A+10A = 43A for the breaker.
The breaker at AC OUT 2 should be 32A or less because the relay that switches AC OUT 2 ON/OFF is only rated for 32A.
I would not recommend to use lead batteries now-days.
