I’m getting ready to move all my breakers to a subpanel, to properly have grid power go to my Growatt 12000t and then to the subpanel.
I’m going to use a 100A breaker from the main panel and 2awg wire to the inverter, and then 2awg wire from the inverter to the subpanel. The inverter has a 80A breaker for input and a 63A breaker for output, and calculating full charge current plus full bypass load is ~75A, anyways I plan on putting a 100A transfer switch to bypass the inverter for maintenance too, so 2awg for the possible 100A is proper anyways.
The largest wire the inverter accepts is 6awg and I wanted to minimize losses, plus it is breakered for 80A which I believe is above the 6awg max anyways.
