HI Dave and Chris, Good points, however.
I’ve had radian board failures which shut it all down. You are correct if a power module goes down then it will still continue working. This project doesn’t need telecomm redundancy but close. And if the inverter shuts down then the AGS won’t start. So yea maybe a bit overkill but its a long long ways to go for a site visit. And again, 50 amps max ( 30 really) and would be good to have built in mechanical bypass.
